IE9 RC fixed the “Internet Explorer cannot display the webpage” error when running an ASP.NET application in Visual Studio

- by Jon Galloway

One of the obstacles ASP.NET developers faced in using the Internet Explorer 9 Beta was the dreaded “Internet Explorer cannot display the webpage” error when running an ASP.NET application in Visual Studio. In the bug information on Connect (issue 601047), Eric Lawrence said that the problem was due to “caused by failure to failover from IPv6 to IPv4 when the connection is local.” Robert MacLean gives some more information as what was going wrong: “The problem is Windows, especially since it assumes IPv6 is better than IPv4. Note […] that when you ping localhost you get an IPv6 address. So what appears to be happening is when IE9 tries to go to localhost it uses IPv6, and the ASP.NET Development Server is IPv4 only and so nothing loads and we get the error.” The Simple Fix - Install IE 9 RC Internet Explorer 9 RC fixes this bug, so if you had tried IE 9 Beta and stopped using it due to problems with ASP.NET development, install the RC. The Workaround in IE 9 Beta If you're stuck on IE 9 Beta for some reason, you can follow Robert's workaround, which involves a one character edit to your hosts file. I've been using it for months, and it works great. Open notepad (running as administrator) and edit the hosts file (found in %systemroot%\system32\drivers\etc) Remove the # comment character before the line starting with 127.0.0.1 Save the file - if you have problems saving, it's probably because you weren't running as administrator When you're done, your hosts file will end with the following lines (assuming you were using a default hosts file setup beforehand): # localhost name resolution is handled within DNS itself. 127.0.0.1 localhost # ::1 localhost Note: more information on editing your hosts file here. This causes Windows to default to IPv4 when resolving localhost, which will point to 127.0.0.1, which is right where Cassini - I mean the ASP.NET Web Development Server - is waiting for it.

Socket(TCPIP) Unstable

- by Lee Kwan Wee

I have a setup of a SCPI server in a Win7 PC and have 2 other programs talking to it locally(127.0.0.1) over TCPIP socket 5025 and 5029. This worked well and stable in a fresh PC, but when we moved it into our production lines and the IT dept added their policies and stuff, it became unstable. The PC is connected to the production floor server but both of the programs are running locally in the PC. The connection tends to be disconnected when there is an idle period. And it takes 5-6times to refreshing the connection to get it back. I'm not a programmer myself, so I'm hoping to see if anyone here can help with some answers. Thank you very much!! Regards, KwanWee.

Howto WCF Service HTTPS Binding and Endpoint Configuration in IIS with Load Balancer?

- by Mike G

We have a WCF service that is being hosted on a set of 12 machines. There is a load balancer that is a gateway to these machines. Now the site is setup as SSL; as in a user accesses it through using an URL with https. I know this much, the URL that addresses the site is https, but none of the servers has a https binding or is setup to require SSL. This leads me to believe that the load balancer handles the https and the connection from the balancer to the servers are unencrypted (this takes place behind the firewall so no biggie there). The problem we're having is that when a Silverlight client tries to access a WCF service it is getting a "Not Found" error. I've set up a test site along with our developer machines and have made sure that the bindings and endpoints in the web.config work with the client. It seems to be the case in the production environment that we get this error. Is there anything wrong with the following web.config? Should we be setting up how https is handled in a different manner? We're at a loss on this currently since I've tried every programmatic solution with endpoints and bindings. None of the solutions I have found deal with a load balancer in the manner we're dealing. Web.config service model info: <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="TradePMR.OMS.Framework.Services.CRM.CRMServiceBehavior"> <serviceMetadata httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> <behavior name="TradePMR.OMS.Framework.Services.AccountAggregation.AccountAggregationBehavior"> <serviceMetadata httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="SecureCRMCustomBinding"> <binaryMessageEncoding /> <httpsTransport /> </binding> <binding name="SecureAACustomBinding"> <binaryMessageEncoding /> <httpsTransport /> </binding> </customBinding> <mexHttpsBinding> <binding name="SecureMex" /> </mexHttpsBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />  <services> <service behaviorConfiguration="TradePMR.OMS.Framework.Services.CRM.CRMServiceBehavior" name="TradePMR.OMS.Framework.Services.CRM.CRMService"> <endpoint address="" binding="customBinding" bindingConfiguration="SecureCRMCustomBinding" contract="TradePMR.OMS.Framework.Services.CRM.CRMService" name="SecureCRMEndpoint" />  <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> <service behaviorConfiguration="TradePMR.OMS.Framework.Services.AccountAggregation.AccountAggregationBehavior" name="TradePMR.OMS.Framework.Services.AccountAggregation.AccountAggregation"> <endpoint address="" binding="customBinding" bindingConfiguration="SecureAACustomBinding" contract="TradePMR.OMS.Framework.Services.AccountAggregation.AccountAggregation" name="SecureAAEndpoint" />  <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> </configuration> The ServiceReferences.ClientConfig looks like this: <configuration> <system.serviceModel> <bindings> <customBinding> <binding name="StandardAAEndpoint"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> <binding name="SecureAAEndpoint"> <binaryMessageEncoding /> <httpsTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> <binding name="StandardCRMEndpoint"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> <binding name="SecureCRMEndpoint"> <binaryMessageEncoding /> <httpsTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> </customBinding> </bindings> <client> <endpoint address="https://Service2.svc" binding="customBinding" bindingConfiguration="SecureAAEndpoint" contract="AccountAggregationService.AccountAggregation" name="SecureAAEndpoint" /> <endpoint address="https://Service1.svc" binding="customBinding" bindingConfiguration="SecureCRMEndpoint" contract="CRMService.CRMService" name="SecureCRMEndpoint" /> </client> </system.serviceModel> </configuration> (The addresses are of no consequence since those are dynamically built so that they will point to a dev's machine or to the production server)

light.exe : error LGHT0217: Error executing ICE action ‘ICE*’ with BizTalk Deployment Framework & TFS 2010 Build.

- by Vishal

Hi there, Recently I was working with BizTalk Deployment Framework v5.0 for my BizTalk Sever 2009 projects and TFS 2010 Builds. I had followed all the steps mentioned in the BTDF documentation to create the build definition and also followed the steps to setup the Build Server with BTDF. After few hiccups I was stuck at this light.exe validation error. The detailed error is as below: light.exe : error LGHT0217: Error executing ICE action 'ICE06'. The most common cause of this kind of ICE failure is an incorrectly registered scripting engine. See http://wix.sourceforge.net/faq.html#Error217 for details and how to solve this problem. The following string format was not expected by the external UI message logger: "The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance." I found few blog posts and forum answers out there which had steps to resolve the error but all of them mentioned different things. Like: Some mentioned that disable the validation itself so that the VBScript would not be called. (I didn’t want to disable the validation.) Another said to put NT AUTHORITY\NETWORK SERVICE in the local Administrators group but this is not recommended as it opens up network security holes. But what actually worked for me was: TFS Build Service Account was part of the Administrator group on the Build Server which is OK. But somehow it was also part of the IIS_IUSR Group. I removed the TFS Build Service Account from the IIS_IUSR group. Queued up my TFS Build but same error. Again after some digging, I found that I had not restarted the Visual Studio Team Build Service. In a Nutshell: Remove TFS Build Service Account from IIS_IUSR Group. Restart the Visual Studio Team Build Service, either from Services or TFS Console. Hope this resolves the issue for someone and not waste bunch of hours. Thanks, Vishal Mody

How to install a Canon iRunner 210s

- by Ssvarc

A client has a Canon iRunner210S and is complaining about slow print speeds. I've searched for a install manual online but came up empty. A call to Canon technical referred me to their dealer network for service, as as informing me that there isn't a manual available on their website. Anyone know how to install these and/or have a link to a manual? The current setup has the printers on a LAN Manager printer port instead of on straight IP ports. Is this normal for this printer? And what exactly are Lan Manager ports (based on my research, they appear to be a way to authenticate a connection)?

Bash on Snow Leopard doesn't obey terminal colours

- by karbassi

With the new version of Snow Leopard, OSX upgraded the bash version to GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0).

Windows Azure AppFabric: ServiceBus Queue WPF Sample

- by xamlnotes

The latest version of the AppFabric ServiceBus now has support for queues and topics. Today I will show you a bit about using queues and also talk about some of the best practices in using them. If you are just getting started, you can check out this site for more info on Windows Azure. One of the 1st things I thought if when Azure was announced back when was how we handle fault tolerance. Web sites hosted in Azure are no much of an issue unless they are using SQL Azure and then you must account for potential fault or latency issues. Today I want to talk a bit about ServiceBus and how to handle fault tolerance. And theres stuff like connecting to the servicebus and so on you have to take care of. To demonstrate some of the things you can do, let me walk through this sample WPF app that I am posting for you to download. To start off, the application is going to need things like the servicenamespace, issuer details and so forth to make everything work. To facilitate this I created settings in the wpf app for all of these items. Then I mapped a static class to them and set the values when the program loads like so: StaticElements.ServiceNamespace = Convert.ToString(Properties.Settings.Default["ServiceNamespace"]); StaticElements.IssuerName = Convert.ToString(Properties.Settings.Default["IssuerName"]); StaticElements.IssuerKey = Convert.ToString(Properties.Settings.Default["IssuerKey"]); StaticElements.QueueName = Convert.ToString(Properties.Settings.Default["QueueName"]); Now I can get to each of these elements plus some other common values or instances directly from the StaticElements class. Now, lets look at the application. The application looks like this when it starts: The blue graphic represents the queue we are going to use. The next figure shows the form after items were added and the queue stats were updated . You can see how the queue has grown: To add an item to the queue, click the Add Order button which displays the following dialog: After you fill in the form and press OK, the order is published to the ServiceBus queue and the form closes. The application also allows you to read the queued items by clicking the Process Orders button. As you can see below, the form shows the queued items in a list and the queue has disappeared as its now empty. In real practice we normally would use a Windows Service or some other automated process to subscribe to the queue and pull items from it. I created a class named ServiceBusQueueHelper that has the core queue features we need. There are three public methods: * GetOrCreateQueue – Gets an instance of the queue description if the queue exists. if not, it creates the queue and returns a description instance. * SendMessageToQueue = This method takes an order instance and sends it to the queue. The call to the queue is wrapped in the ExecuteAction method from the Transient Fault Tolerance Framework and handles all the retry logic for the queue send process. * GetOrderFromQueue – Grabs an order from the queue and returns a typed order from the queue. It also marks the message complete so the queue can remove it. Now lets turn to the WPF window code (MainWindow.xaml.cs). The constructor contains the 4 lines shown about to setup the static variables and to perform other initialization tasks. The next few lines setup certain features we need for the ServiceBus: TokenProvider credentials = TokenProvider.CreateSharedSecretTokenProvider(StaticElements.IssuerName, StaticElements.IssuerKey); Uri serviceUri = ServiceBusEnvironment.CreateServiceUri("sb", StaticElements.ServiceNamespace, string.Empty); StaticElements.CurrentNamespaceManager = new NamespaceManager(serviceUri, credentials); StaticElements.CurrentMessagingFactory = MessagingFactory.Create(serviceUri, credentials); The next two lines update the queue name label and also set the timer to 20 seconds. QueueNameLabel.Content = StaticElements.QueueName; _timer.Interval = TimeSpan.FromSeconds(20); Next I call the UpdateQueueStats to initialize the UI for the queue: UpdateQueueStats(); _timer.Tick += new EventHandler(delegate(object s, EventArgs a) { UpdateQueueStats(); }); _timer.Start(); } The UpdateQueueStats method shown below. You can see that it uses the GetOrCreateQueue method mentioned earlier to grab the queue description, then it can get the MessageCount property. private void UpdateQueueStats() { _queueDescription = _serviceBusQueueHelper.GetOrCreateQueue(); QueueCountLabel.Content = "(" + _queueDescription.MessageCount + ")"; long count = _queueDescription.MessageCount; long queueWidth = count * 20; QueueRectangle.Width = queueWidth; QueueTickCount += 1; TickCountlabel.Content = QueueTickCount.ToString(); } The ReadQueueItemsButton_Click event handler calls the GetOrderFromQueue method and adds the order to the listbox. If you look at the SendQueueMessageController, you can see the SendMessage method that sends an order to the queue. Its pretty simple as it just creates a new CustomerOrderEntity instance,fills it and then passes it to the SendMessageToQueue. As you can see, all of our interaction with the queue is done through the helper class (ServiceBusQueueHelper). Now lets dig into the helper class. First, before you create anything like this, download the Transient Fault Handling Framework. Microsoft provides this free and they also provide the C# source. Theres a great article that shows how to use this framework with ServiceBus. I included the entire ServiceBusQueueHelper class in List 1. Notice the using statements for TransientFaultHandling: using Microsoft.AzureCAT.Samples.TransientFaultHandling; using Microsoft.AzureCAT.Samples.TransientFaultHandling.ServiceBus; The SendMessageToQueue in Listing 1 shows how to use the async send features of ServiceBus with them wrapped in the Transient Fault Handling Framework. It is not much different than plain old ServiceBus calls but it sure makes it easy to have the fault tolerance added almost for free. The GetOrderFromQueue uses the standard synchronous methods to access the queue. The best practices article walks through using the async approach for a receive operation also. Notice that this method makes a call to Receive to get the message then makes a call to GetBody to get a new strongly typed instance of CustomerOrderEntity to return. Listing 1 using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.AzureCAT.Samples.TransientFaultHandling; using Microsoft.AzureCAT.Samples.TransientFaultHandling.ServiceBus; using Microsoft.ServiceBus; using Microsoft.ServiceBus.Messaging; using System.Xml.Serialization; using System.Diagnostics; namespace WPFServicebusPublishSubscribeSample { class ServiceBusQueueHelper { RetryPolicy currentPolicy = new RetryPolicy<ServiceBusTransientErrorDetectionStrategy>(RetryPolicy.DefaultClientRetryCount); QueueClient currentQueueClient; public QueueDescription GetOrCreateQueue() { QueueDescription queue = null; bool createNew = false; try { // First, let's see if a queue with the specified name already exists. queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.GetQueue(StaticElements.QueueName); }); createNew = (queue == null); } catch (MessagingEntityNotFoundException) { // Looks like the queue does not exist. We should create a new one. createNew = true; } // If a queue with the specified name doesn't exist, it will be auto-created. if (createNew) { try { var newqueue = new QueueDescription(StaticElements.QueueName); queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.CreateQueue(newqueue); }); } catch (MessagingEntityAlreadyExistsException) { // A queue under the same name was already created by someone else, // perhaps by another instance. Let's just use it. queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.GetQueue(StaticElements.QueueName); }); } } currentQueueClient = StaticElements.CurrentMessagingFactory.CreateQueueClient(StaticElements.QueueName); return queue; } public void SendMessageToQueue(CustomerOrderEntity Order) { BrokeredMessage msg = null; GetOrCreateQueue(); // Use a retry policy to execute the Send action in an asynchronous and reliable fashion. currentPolicy.ExecuteAction ( (cb) => { // A new BrokeredMessage instance must be created each time we send it. Reusing the original BrokeredMessage instance may not // work as the state of its BodyStream cannot be guaranteed to be readable from the beginning. msg = new BrokeredMessage(Order); // Send the event asynchronously. currentQueueClient.BeginSend(msg, cb, null); }, (ar) => { try { // Complete the asynchronous operation. // This may throw an exception that will be handled internally by the retry policy. currentQueueClient.EndSend(ar); } finally { // Ensure that any resources allocated by a BrokeredMessage instance are released. if (msg != null) { msg.Dispose(); msg = null; } } }, (ex) => { // Always dispose the BrokeredMessage instance even if the send // operation has completed unsuccessfully. if (msg != null) { msg.Dispose(); msg = null; } // Always log exceptions. Trace.TraceError(ex.Message); } ); } public CustomerOrderEntity GetOrderFromQueue() { CustomerOrderEntity Order = new CustomerOrderEntity(); QueueClient myQueueClient = StaticElements.CurrentMessagingFactory.CreateQueueClient(StaticElements.QueueName, ReceiveMode.PeekLock); BrokeredMessage message; ServiceBusQueueHelper serviceBusQueueHelper = new ServiceBusQueueHelper(); QueueDescription queueDescription; queueDescription = serviceBusQueueHelper.GetOrCreateQueue(); if (queueDescription.MessageCount > 0) { message = myQueueClient.Receive(TimeSpan.FromSeconds(90)); if (message != null) { try { Order = message.GetBody<CustomerOrderEntity>(); message.Complete(); } catch (Exception ex) { throw ex; } } else { throw new Exception("Did not receive the messages"); } } return Order; } } } I will post a link to the download demo in a separate post soon.

DD-WRT with native IPv6

- by Matt

My ISP provides native IPv6 support (ie. I can plug in my computer straight into the WAN and get an IPv6 address). However I can not get this working on DD-WRT. When I enable IPv6 and radvd in DD-WRT, the router gets in IPv6 address, but the devices on my LAN do not. I tried looking at the DD-WRT wiki, but this only displayed instructions for tunneling or other methods where native support isn't available. I found a small amount of sites thorough searching, but none of the methods these sites described gave my computers each a global IPv6 address. In addition, SSHing into the router using ping6 on sites such as ipv6.google.com causes "host unreachable" errors. Has anyone using DD-WRT configured a successful setup with native IPv6? I am using a Netgear WNDR3700 v2, with DD-WRT build 17201

Wireless Repeating with Netgear N750 (WNDR4300)

- by jomo1911

I have a Netgear N750 as my main router, which connects to the internet via a modem. I have a second Netgear N750 which I want to use to repeat the wireless signal of the main router. I logged in to routerlogin of my main router (192.168.1.1) and set up the "Wireless Repeating Function". I set it as the "Wireless Base Station" and filled in the MAC adress of my second Netgear N750. Then I logged in to routerlogn of my second router and set it up as the "Wireless Repeater", I gave it the IP 192.168.1.11 and filled in the MAC adress of the base station. During the setup of the second router (Repeater) I had to disable all security functions. If I connect to the repeaters' WLAN signal, I get no internet connection. Maybe you can help me, thanks

DD-WRT Router acting as a Switch and Wi-Fi AP

- by dotnetchris

Recently I upgraded to Comcast Business and their modem has a built-in router so I took off my DD-WRT router and moved to a location in my home where I needed more ports and Wi-Fi (preferably without running new Ethernet cables since it's 50-100 foot run through floor and ceilings). I have my network cable from my Comcast modem going into Port 1 of my DD-WRT router with Port 2 and 3 being networked PCs. I have DD-WRT setup as a DHCP forwarder with the firewall disabled. This lets my all of my devices access the network fine. Is the correct the way to do this? Or is this a less optimal solution and it should be done in a slightly different way?

Trying to configure DNS on a Godaddy Virtual Dedicated host, Mediatemple Domain Registration

- by dclowd9901

A client of mine purchased VD hosting with Godaddy and a domain name with Mediatemple. I've never configured DNS from scratch, and I'm finding it very difficult to find any sort of explanation on how to go about it. As of right now, Mediatemple is pointing to the Godaddy's ns1.domaincontrol.com and ns2.domaincontrol.com nameservers. The VD hosting on Godaddy (via their Simple Control Panel) has options to "Add a new domain", which brings you through a wizard of sorts that asks you if the domain has already been registered (yes), what it is (dclowd9901.com for this example), create a system username and password for it (with checkboxes for SSH and FTP access), which level of user can administer it, and whether a mail account should be setup. When complete, it also creates a zone file. In this zone file, the Primary nameserver is ns1.dclowd9901.com; the records are as follow (where 12.23.12.34 is the presumed host): @ A 12.23.12.34 @ NS ns1 @ NS ns2 ns1 A 12.23.12.34 ns2 A 12.23.12.34 @ MX mail www A 12.23.12.34 ftp A 12.23.12.34 ssh A 12.23.12.34 mail A 12.23.12.34 If anyone can shed any light on this for me, explain to me the interactions between the registrar and the host and so on, I'd be very grateful. Thanks in advance for the help.

Setting up Lan within a Lan

- by nageeb

How unreasonable would it be to setup a small LAN within an existing LAN? I'm setting up a series of video surveillance servers and a number of IP cameras in a client's location and cannot have my equipment on the same network as their local machines. My network is essentially self-contained and the only device that anyone needs to access is a web-app on one of the machines. Basically I'm thinking of installing a SOHO router which would uplink to their LAN, and then set up some NAT rules on both their router and my router, to allow outside access to the webserver. Is there anything fundamental that i'm missing which would prevent this from working?

Using Fiddler with BizTalk's HTTP Adapter

- by Christopher House

I'm working on an orchestration that's retrieving some data from a Java servlet. The servlet takes a parameter string via HTTP post and returns POX (plain old XML, no SOAP here). I was having trouble getting a valid response from the servlet when I was sending some test messages and wanted to see what my messages were looking like as they went across the wire. Normally I was using WCF, I'd setup message logging, but since that's obviously not an option with the HTTP adapter, my thoughts turned to Fiddler. A quick Google search turned up some promising results. The posts I read all referred to using Fiddler with the SOAP adapter, but I thoght I could apply the same ideas to the HTTP adapter. This led me to try setting the following context properties: HttpRequestMessage(HTTP.UseProxy) = true; HttpRequestMessage(HTTP.ProxyName) = "127.0.0.1"; HttpRequestMessage(HTTP.ProxyPort) = 8888; I rebuilt my orch, gac'd it, bounced my host and tried submitting a test message. Fiddler was running but I didn't see any traffic show up. I tried fully undeploying/redeploying my application and still, no traffic in Fiddler. I was starting to think that BizTalk was ignoring the proxy settings. To confirm this, I closed Fiddler and submitted a test message. Sure enough, the orch ran to completion, proving that BizTalk was ignoring the proxy settings. I went back to my orch to see if there could be any other context proprties I needed to set. I saw one that looked promising: HTTP.UseHandlerProxySettings. I set this to false, rebuilt my orch and this time when I submitted, I got an error message, which made sense, I didn't have Fiddler running. I started up Fiddler, submitted another message and there it was, my HTTP traffic, just as I hoped. And, I was quickly able to figure out what the problem was...I had forgotten to set HTTP.ContentType to application/x-www-form-urlencoded.

ISA Proxy - HTTPS Traffic

- by x100

We have an ISA 2006 setup for our organisations proxy. It's been working well for the last few months just blocking everything except a few allowed web site and web applications. We need to allow some people to access a web application hosted off site via HTTPS. I've tried and tried, wasted 3 days on it and have given in. Can someone please tell me how on earth this is achieved? Looking at the Monitor, it looks like it passes one rule, then is blocked by the default rule. I just don't unterstand it well enough to take it on further.

SOA Suite Integration: Part 2: A basic BPEL process

- by Anthony Shorten

This is the next in the series about SOA Suite integration with Oracle Utilities Application Framework. One of the first scenarios I am going to illustrate in this series is building a basic BPEL process using Web Service calls to the Oracle Utilities Application Framework. The scenario is this. I will pass in the userid and the BPEL process will call our the AS-User Web Service we created in Part 1. This is just a basic test and illustrate how to import the Web Service into SOA Suite. To use this scenario, you will need access to Oracle SOA Suite, access to a copy of any Oracle Utilities Application Framework based product and Oracle JDeveloper (to build the process). First of all you need to start Oracle JDeveloper and create a new SOA Project to house the BPEL process in. For the purposes of this example I will call the project simpleBPEL and verify that SOA is part of the project. I will select "Composite with BPEL" to denote it as a BPEL process. I can also the same process to create a Mediator or OSB project (refer to the JDeveloper documentation on these technologies). For this example I will use BPEL 1.1 as my specification standard (BPEL 2.0 can also be used if desired). I give the individual BPEL process as simpleBPEL (you can use a different name but I wanted to keep the project and process the same for this example). I will also build a Synchronous BPEL Process as I want a response from the Web Service. I will leave the defaults to save time. I have no have a blank canvas to build my BPEL process against. Note: for simplicity I am going to use as much defaulting as possible. In fact I am not going to specify an input schema for the incoming call as I will use the basic single field used by BPEL as default. The first step is to import the AS-User Web Service into my BPEL project. To do this I use the standard Web Service BPEL component from the Component Palette to import the WSDL into the BPEL project. Now the tricky part (a joke), you drag and drop the component from the Palette onto the right side of the canvas in the Partner Links swim lane. This swim lane is reserved for Partner Links that have a Partner Role (i.e. being called rather than calling). When you drop the Web Service onto the canvas the Create Web Service wizard is invoked to ask for details of the Web Service. At this point you give the BPEL node a name. I have used the name RetrieveUser as a name. I placed the WSDL URL from the XAI Inbound Service screen in the WSDL URL. Once you specify the URL you can press the Find existing WSDL's button to load the information into BPEL from the call. You will notice the Port Type is prefilled with the port from the WSDL. I also suggest that you check copy wsdl and it's dependent artifacts into the project if you intending to work on the BPEL process offline. If you do not check this your target application must be accessible when you work on the BPEL process (that is not always convenient). Note: For the perceptive of you will notice that the URL specified in this example is different to the URL in the last post. The reason is for the demonstrations I shifted to a new server and did not redo all of the past screen captures. If you copy the WSDL into the project you will get an information screen about Localize Files. It is just a confirmation screen. The last confirmation screen is a summary of the partner link (the main tab is locked for editing at this stage). At this stage you have successfully imported the Web Service. To complete the setup of the Web Service you need to set the credentials for the Web Service to use. Refer to the past post on how to do that. Now to use the Web Service. To call the Web Service (as it is just imported not connected to the BPEL process yet), you must add an Invoke action to your BPEL Process. To do this, select Invoke action from the BPEL Constructs zone on the Component Palette and drop it on the edit nodes between the receiveInput and replyOutput nodes This will create an empty Invoke action. You will notice some connectors on the Invoke node. Grab the node closest to your Web Service and drag it to connect the Invoke to your Web Service. This instructs BPEL to use the Invoke to call the Web Service. Once the Invoke action is connected to the Web Service an Edit Invoke edit dialog is displayed. At this point I suggest you name the Invoke node. It is important to name the nodes straightaway and name them appropriately for you to trace the logic. I used InvokeUser as the name in this example. To complete the node configuration you must create Variables to hold the input and output for the call. To do this clock on Automatically Create Input Variable on the Edit Invoke dialog. You will be presented with a default variable name. It uses the node name (that is why it is important to name the node before hitting this button) as a prefix. You can name the variable anything but I usually take the default. Repeat the same for the output variable. You now have a completed node for invoking the service. You have a very basic BPEL process which contains an input, invoke and output node. It is not complete yet though. You need to tell the BPEL process how to pass data from the input to the invoke step and how to take the output from the service call and pass it back to the service. You need to now add an Assign node to assign the input to the Web Service. To do this select Assign activity from BPEL Constructs zone in the Component Palette. Drag and drop the Assign activity between the receiveInput and InvokeUser nodes as you want to pass data between these two nodes. You have now added a new Assign node to your BPEL process Double clicking the node allows you to specify the name of the node. I use AssignUser to describe that I am assigning user data. On the Copy Rules tab you can specify the mapping between the input variable InputVariable/payload/process/input string and the input variable for the Web Service call. We are passing data from the input to BPEL to the relevant input variable on the Web Service. This is simply drag and drop between the two data structures. In the example, I am using the input to pass to the user element in my Web Service as the user is the primary key for the object. The fields become linked (which means data from source will be copied to target). Almost there. You now need to process the output from the Web Service call to the outputVariable of the client call. I have decided to pass back one piece of data, the name associated with the user by concatenating the firstName and lastName elements from the Web Service call. To do this I will use a Transform as it is not just a matter of an Assign action. It is a concatenation operation. This also illustrates how you can use BPEL functionality to transform data from a Web Service call. As with the other components you drag and drop the Transform component to the appropriate place in the BPEL process. In this case we want to transform the output from the Web Service call so we want it after the InvokeUser action and the replyOutput action. The Transform component is actually part of the Oracle Extensions to the BPEL specification. Double clicking the Transform node will allow you to name the node. In this example I used TransformName. To complete the transform I need to tell the product the source of the transformation and the target of the transform. In the example this is the InvokeUser output variable. I also named the mapper file to TransformName. By clicking the + or pencil icon next to the map I can create the map. The mapping screen is shows the source and target schemas for me to map across. As with the assign I can map the relevant elements. In my example, I first map the firstName from the Web Service to the result element. As I want to concatenate the names, I drop the concat function on the call line. I now attach the last name to the function to indicate the concatenation of the field. By default the names will be concatenated with no space. To make the name legible I add a space between the field by clicking the function and adding a space in the call. I now have a completed mapping. I can now save the whole project as my BPEL process is now complete. As you can see the following happens: We accept input from the client (the userid for the call) in the receiveInput step. We assign that value to the input parameters for the Web Service call in the AssignUser step. We invoke the Web Service call to retrieve the data from the product in the InvokeUser step. We take the output from the InvokeUser step and concatenate the names in the TransformName step. We pass back the data in the replyOutput step. At this point we can deploy the BPEL process to the SOA Suite server. I will not cover this aspect as it really all SOA Suite specific (it is all done via Oracle JDeveloper). Now we need to test the service in SOA Suite. We will use the Fusion Middleware Control test facility. I will assume that credentials have also been setup as per our previous post (else you will get a 401 error). You navigate to the deployed BPEL process within Fusion Middleware Control and select the Test Service option. Specify some test data on the payload at the bottom of the Test Service screen. In my case I am returning my own userid information. On the response tab you will see the result. It works. You can verify the steps using the Audit trace facility on individual calls. As you can see this is a basic BPEL but you get the idea of importing the Web Service is pretty straightforward. You can create more sophisticated BPEL processes using the full facilities in Oracle SOA Suite. I just showed you the basic principals.

Find which config file Apache uses to find virtual host

- by eje211

I have a rather complicated Apache setup: some config files have to be manually written and some have to be automatically generated. So far, I've had no problems. But now, I've just tried to set a site at: newsubdomain.mydomain.com and Apache directs it to the data for: www.someotherdomain.com I've looking into all the many config files and can't find anything wrong. All is pointing where it should and no definitions, as far as I can tell, overlap. So what I'm wondering is: is there a way to see which config files or config instructions Apache is using to match a URL to a directory? Tanks.

GnuPG PHP gnupg Folder & Files Permission

- by Michael Robinson

Situation: we plan on using PHP's GnuPG extension to encrypt/decrypt files. Currently we've setup some test cases, using keys generated with GPG. The generated files reside in: /Users/username/.gnupg/ I am able to get keyinfo for the key I want to use to encrypt/decrypt, but when I attempt to use addencryptkey, I get: (E_WARNING: 2): gnupg::addencryptkey() [gnupg.addencryptkey]: get_key failed I think this is due to the permissions on the ~/.gnupg folder & enclosed files. The files are owned by me - username, but apache runs as www. A few days ago I did have this working, but it seems each time I use GPG Keychain Access to import / export a key, the folder's permissions are changed. Question: What are the exact permissions required to allow PHP's GnuPG to add encrypt & decrypt keys?

Can't RDP Into Windows Server After Windows Server Establishes VPN Session

- by Jennifer Baker

Hi there. I've setup a Windows 2008 Server in a Cloud Environment. I am able to RDP to this Windows Server ("aka CloudServer") in the Cloud Environment. When I establish PPTP VPN connection from the CloudServer back to our Windows Server ("aka OfficeServer"), my RDP session is dropped and it won't let me RDP back in. The only way how I can RDP to the CloudServer is using the DHCP ip address issued from the OfficeServer. What do I need to change on the CloudServer? Thanks in advance for your help! Jennifer

Configuring RAID1 on HP Proliant Microserver N54L / Ubuntu 14.04.1 LTS [duplicate]

- by Chris Beach

This question already has an answer here: Cant find my harddrives in ubuntu installation? 2 answers I've bought a N54L and fitted two 3GB drives. Keen to get set up with RAID1. BIOS: SATA controller mode set to "RAID" RAID Option ROM utility: both physical drives set up as one logical drive When I came to install Ubuntu (14.04.1), both drives appeared during the setup process. I was only expecting to see the logical drive, although I'm a complete novice with RAID. I've read that the HP Proliant Microservers don't have "proper" RAID support, and require some kind of driver to be installed. I've tried a few HP utilities from the following apt repo: deb http://downloads.linux.hp.com/SDR/repo/mcp wheezy/current non-free On installation, most say "server not supported" Would appreciate your advice.

SFTP jail & Keeping file ownership the same / File owner per folder

- by Dragonshadow

I want to setup a jailed SFTP account for a subfolder of another user's home folder, but want the owner of everything in that subfolder to stay the same, including new files and folders uploaded and created by the sftp user, while still allowing access to the files and folders of that subfolder as if the SFTP user was the parent user. rawny bawb-sftp /home/rawny <- rawny owns this /home/rawny/sftp <- rawny owns this too, but bawb-sftp can upload to it, edit files, etc bawb-sftp uploads a file /home/rawny/sftp/lol.txt rawny should still own the file, as if he made it in the first place, even though bawb-sftp was the one that uploaded it. Basically I guess I'm asking for an sftp jail that acts as a highly limited passthrough/puppet for another user?
