  • Sanitizing incoming XML via WCF

    - by Clark
    I am consuming a Java webservice from .net using WCF. I am getting an error on deserialization of a response from the Java service The byte 0x00 is not valid at this location. Line 1, position 725. I know from some research that this is an incorrectly encoded null, but I am unlikely to get the provider to change it, so I would like to sanitize the null out before WCF deserializes the return message. Any Ideas? I am using c#, but answers in any CLR language will do.

  • Create a string with the result of an expression and the expression that originated the value. Is it

    - by Oscar Reyes
    Like String r = SomeThing.toExecString("new Object().toString()"); And when executed the value of r would be: "new Object().toString() = java.lang.Object@c5e3974" Is this even possible at all? Would it need a bunch of reflection? A built in compiler maybe? AFAIK, this is not possible with regular Java. The closest thing I could get is IDE support like in IDEA with the "macro" soutv+tab that prints: Hit taband type the expression The IDE types the rest for you. But that's quite another completely thing.

  • Set up router to vpn into proxy server

    - by NKimber
    I have a small network with a single LinkSys router connected to broadband in US via Comcast. I have a VPN proxy server account that I can use with a standard Windows connection, allowing me to have a geographic IP fingerprint in Europe, this is useful for a number of purposes. I want to setup a 2nd router that automatically connects via VPN to this proxy service, so any hardware that is connected to router 2 looks as though it is originating network requests in Europe, and any hardware connected to my main router has normal Comcast traffic (all requests are originating from USA). My 2nd router is a LinkSys WRT54G2, I'm having trouble getting this configured. Question, is what I'm trying to do even feasible? Should the WRT54G2 be able to do this with native functionality? Would flashing it with DD-WRT allow me to achieve my objectives? Any help/suggestions much appreciated. Neil

  • JSF : able to do mass update but unable to update a single row in a datatable

    - by nash
    I have a simple data object: Car. I am showing the properties of Car objects in a JSF datatable. If i display the properties using inputText tags, i am able to get the modified values in the managed bean. However i just want a single row editable. So have placed a edit button in a separate column and inputText and outputText for every property of Car. the edit button just toggles the rendering of inputText and outputText. Plus i placed a update button in a separate column which is used to save the updated values. However on clicking the update button, i still get the old values instead of the modified values. Here is the complete code: public class Car { int id; String brand; String color; public Car(int id, String brand, String color) { this.id = id; this.brand = brand; this.color = color; } //getters and setters of id, brand, color } Here is the managed bean: import java.util.ArrayList; import java.util.List; import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped; import javax.faces.component.UIData; @ManagedBean(name = "CarTree") @RequestScoped public class CarTree { int editableRowId; List<Car> carList; private UIData myTable; public CarTree() { carList = new ArrayList<Car>(); carList.add(new Car(1, "jaguar", "grey")); carList.add(new Car(2, "ferari", "red")); carList.add(new Car(3, "camri", "steel")); } public String update() { System.out.println("updating..."); //below statments print old values, was expecting modified values System.out.println("new car brand is:" + ((Car) myTable.getRowData()).brand); System.out.println("new car color is:" + ((Car) myTable.getRowData()).color); //how to get modified row values in this method?? return null; } public int getEditableRowId() { return editableRowId; } public void setEditableRowId(int editableRowId) { this.editableRowId = editableRowId; } public UIData getMyTable() { return myTable; } public void setMyTable(UIData myTable) { this.myTable = myTable; } public List<Car> getCars() { return carList; } public void setCars(List<Car> carList) { this.carList = carList; } } here is the JSF 2 page: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form id="carForm" prependId="false"> <h:dataTable id="dt" binding="#{CarTree.myTable}" value="#{CarTree.cars}" var="car" > <h:column> <h:outputText value="#{car.id}" /> </h:column> <h:column> <h:outputText value="#{car.brand}" rendered="#{CarTree.editableRowId != car.id}"/> <h:inputText value="#{car.brand}" rendered="#{CarTree.editableRowId == car.id}"/> </h:column> <h:column> <h:outputText value="#{car.color}" rendered="#{CarTree.editableRowId != car.id}"/> <h:inputText value="#{car.color}" rendered="#{CarTree.editableRowId == car.id}"/> </h:column> <h:column> <h:commandButton value="edit"> <f:setPropertyActionListener target="#{CarTree.editableRowId}" value="#{car.id}" /> </h:commandButton> </h:column> <h:column> <h:commandButton value="update" action="#{CarTree.update}"/> </h:column> </h:dataTable> </h:form> </h:body> </html> However if i just keep the inputText tags and remove the rendered attributes, i get the modified values in the update method. How can i get the modified values for the single row edit?

  • Eclipse IDE's Hello World Cheatsheet seems to have a mistake

    - by Sean
    Hey guys, Just a warning: I'm completely new to Java and am trying to teach myself Android programming. I installed the Eclipse IDE today and tried to walk through the first Java Hello World "cheat sheet," and it didn't work! I was really quite surprised. When it asked me to select the checkbox to create the main() method, there wasn't anything on-screen that looked like a checkbox with "main()" or "method" next to it, so I guessed that maybe what they meant was the "Modifiers" radio button. So I left that checked for "public." It didn't compile and I got red X's next to every folder in my Package Explorer. Has anybody else had this problem? Thanks!

  • IIS7 - Web Deployment Tool - SetParam/SetParamFile to set http and https bindings + Cert

    - by Andras Zoltan
    Hi, we're currently using the MS Web Deployment Tool to sync a live website and some WebServices from a staging box to two live servers. The staging box hosts the site on any IP on port 17000, whereas the two live servers are load-balanced and have a different IP for each of them. At present, I generate two separate packages for deployment - one for each machine - using the sync operation and specifying a DestinationBinding parameter as follows: msdeploy -verb:sync -source:WebServer,computerName=localhost -dest:package="machinename.zip" -setParam:type="DestinationBinding",scope="SiteName",value="ip_address:port:". (Split across multiple lines to make it easier to read!) I run this twice, with a different target filename and ip address for each of the two machines. When it comes to deployment, I simply do a sync from each package to its respective live site. I know, I know - I should be able to do it by generating one parameterised package and then perhaps using the SetParamFile switch for each of the two Servers - believe me I'd like to, but the documentation on doing this is frankly non-existent. Now I need to configure and deploy both HTTP and HTTPS binding for this site; including also the ssl cert that is to be used. I've added an SSL binding for the site on the staging box - which uses a development cert (which will need to be replaced - or should the staging box be using the live cert?), and now the above command line has the effect of replacing the target IP on both http and https entries. It appears that I cannot specify multiple bindings plus the cert information in the DestinationBinding value in the -setParam above, so anyone know how would I go about doing this? Any help greatly appreciated.

  • App engine datastore - query on Enum fields.

    - by Gopi
    I am using GAE(Java) with JDO for persistence. I have an entity with a Enum field which is marked as @Persistent and gets saved correctly into the datastore (As observed from the Datastore viewer in Development Console). But when I query these entities putting a filter based on the Enum value, it is always returning me all the entities whatever value I specify for the enum field. I know GAE java supports enums being persisted just like basic datatypes. But does it also allow retrieving/querying based on them? Google search could not point me to any such example code. Details: I have printed the Query just before being executed. So in two cases the query looks like - SELECT FROM com.xxx.yyy.User WHERE role == super ORDER BY key desc RANGE 0,50 SELECT FROM com.xxx.yyy.User WHERE role == admin ORDER BY key desc RANGE 0,50 Both above queries return me all the User entities from datastore in spite of datastore viewer showing some Users are of type 'admin' and some are of type 'super'.

  • Dividing a Video into Frames and Sending Frames to Streams

    - by Amit Kumar
    I have to implement a "demux" that divides up a video stream and sends each frame to one of multiple output streams in a round-robin fashion. I am trying to implement the demux as follows. The video stream contains one frame after another and is implemented via a java InputStream. Each frame has a frame header followed by the image data. The demux needs to read the frame header to know the size of the image data. The image data can then be redirected from the input video stream to one of the output streams (java OutputStream). My problem is about how to implement this redirection. That is, connect the InputStream to the OutputStream to send N bytes (here N is the size of the image data), and then disconnect and connect to another OutputStream. I have seen the interface of PipedInputStream etc but they do not seem to implement the disconnection.

  • Set default tab url in firefox 14

    - by sebster
    In the latest firefox update, new tabs show -instead of the previously default blank page- a window of recently viewed pages. Before this was available, I had installed an 'addon' to allow this (called 'fvd speed dial'). It worked fine however I have since delete.d this as it is no longer needed but still loads the page where the addon was housed:'chrome://fvd.speeddial/content/fvd_about_blank.html'. I have reinstalled firefox yet the same problem still occurs. On the 'about:config' page I have found the setting 'browser.newtab.url' but do not know the default url. Is there any way to remedy this? I will just add, I appologise if this is not the case with the new tab feature. It is all I have gathered from the firefox update page. Also, I do not want to, ideally, simply restore my settings as I have changed some of them (such as the search bar, that work fine. I am on windows-xp, home edition. Not sure of what service pack.

  • Can't set up IIS Web Server on Server 2008 x64 correctly

    - by balexandre
    Using a VM I installed Windows 2008 Server x64 and as the image below shows, added the IIS Role full image and assigned all role features of IIS full image But if I have an ASP.NET (aspx) page that does (C#) Session["test-session"] = "A"; and read in other page I always get nothing! NOTE: I do have an entire ASP.NET web application, the example above is to be succinct and explicit on what is the problem I'm facing. Can anyone know what do I have to do to the Server, so I can use the Session variables? All help is greatly appreciated, Thank you

  • Inverse Logistic Function / Reverse Sigmoid Function

    - by Chanq
    I am currently coding up a fuzzy logic library in java. I have found the equations for all the standard functions - Grade, inverseGrade, Triangle, Trapezoid, Gaussian. However, I can't find the inverse of the sigmoid/ logistic function. The way I have written the logistic function is java is : //f(x) = 1/(1+e(-x)) public double logistic(double x){ return (1/(1+(Math.exp(-x))); } But I can't work out or find the inverse anywhere. My algebraic/calculus abilities are fairly limited, hence why I haven't been able to work out the inverse of the function. Any hints or pointers would be a big help. Thanks

  • Cannot connect to *.dbf file through JDBC drivers

    - by leodali
    i'm trying to connect to *.dbf (dBase III) file on my Java application, running on a Windows Server 2003 system. I'm encountering this error and I cannot really understand the meaning (sources for OdbcJdbc.java seems to be unavailable): [Microsoft][ODBC dBase driver] '(unknown)' is not a valid path error Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); String database = "jdbc:odbc:DRIVER={Microsoft dBase Driver(*.dbf)};DBQ=D:\\dbNeri\\CARISTAT;"; Connection conn = DriverManager.getConnection(database); Statement s = conn.createStatement(); String selTable = "SELECT * FROM CARISTAT"; Does it exists a JDBC driver able to connect to dBase files or do I have to import external libraries to do the magic? Thanks in advance for your help!

    - by michael
    Hi, In w3c dom interface, there is DOMTreeWalker to traverse the DOM. I find this example which uses DOMTreeWalker: http://www.java-tips.org/java-se-tips/org.w3c.dom/how-to-traverse-the-dom-tree-using-treewalker-2.html But my question is How can I use the DOMTreeWalk to dump the dom structure and value to a file? i.e. I need to know when a parent start and a parent end so that I can do when I dump the dom to a file (i need to insert after each parent dumps its children: <parent> <child a1="1" a2="2"/> <child a3="1" a4="3"/> <child a5="1" a6="5"/> </parent>

  • What's the easiest way to get the result of an HTTP GET request in using URL in JRuby

    - by sipwiz
    I'm attempting to build a Tropo Ruby application and I need to retrieve the result of an HTTPS GET. The Tropo platform doesn't have the httpclient Ruby gem so I can't use that. The Ruby engine used is JRuby so a suggestion has been to make use of the Java URL class to do the request. I've played around with it a little bit and I seem to be able to create the URL object ok but am now struggling with how to get the results of executing the request. How do I do it? javaURL = java.net.URL.new svcURL transferResult = javaURL.getContent()

  • how to push data from BlazeDS without recieve message from Flex client?

    - by Teerasej
    Hi, everyone I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer, so I think you can help me. In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want? How to configure the message-config.xml to get the result like I describe above?

  • After using modern languages, can C NOT be painful?

    - by Alexandre
    I started my computer engineering course recently and we've been using C for a couple of things. Before starting university, I was doing a lot of web development. I've written a lot of PHP code (yuck!) and for the last year or so Ruby exclusively. aside: I love Ruby, love it! So after a year of heavy Ruby development, is it wrong to think that C should be avoided at all costs unless absolutely necessary? Right now it seems to me I should try to a) get it to run in Ruby b) if it's too slow, try Java c) if it's too slow, use C Is there anyone who jumps straight to C if a VM (Ruby, Java, Python, etc) can be used on the machine and speed is not an issue? In other words, can C NOT be painful?

  • Programming an Event listener for files in a directory on Linux

    - by Epitaph
    On Ubuntu linux, when you watch a flash video, it gets saved temporarily in the /tmp as flv files while the video buffers. I use vlc to directly play these files. Currently, I have scripted a shortcut that directly scans and opens the latest file in /tmp with vlc, when clicked. But, I want to program a Java application that will continually monitor this /tmp directory for any new flv files, and open it in vlc automatically. I know I can use Runtime.exec() to open the VLC application with the flv files. But, I DO NOT want to run a while(true) loop (with sleep) to scan for files. How can I make use of Event Handling (Java or any other language) on Linux to complete this task?
