  • Problem with Apache Commons Id UUID Version 1 generation

    - by Pekka Mattila
    My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

    - by Pure.Krome
    Hi folks, i have a simple aspx page. Here's the top of it:- <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Foo.aspx.cs" Inherits="Foo" %> <%@ OutputCache Duration="3600" VaryByParam="none" Location="Any" %> Now, every time I hit the page in FireFox (either hit F5 or hit enter in the url bar) I keep getting a 200 OK response.

  • java OutofMemoryError

    - by dqm
    I am running the following command on unix box. java -Xms3800m -Xmx3800m org.apache.xalan.xslt.Process -out Cust.txt -in test13l.xml -xsl CustDetails.xsl It is a java command, which calls Xalan processor to parse through the xml file (test131.xml) using the xsl stylesheet (CustDetails.xsl) and returns Cust.txt. The command works fine and the output is generated. It takes 12 minutes to process an xml file size of 1.1 GB. It takes 22 minutes to process a file size of 1.44 GB. However, when I try to process a file size of 1.66 GB, it errors out with the following message: (Location of error unknown)XSLT Error (java.lang.OutOfMemoryError): null I have increased the java heap size to 3800 not sure what I can do more. Many thanks for your help.

  • Getting the executed output of an aspx page after a short delay

    - by Ankur
    Hi all, I have an aspx page which has some javascript code like <script> setTimeout("document.write('" + place.address + "');",1); </script> As it is clear from the code it will going to write something on the page after a very short delay of 1 ms. I have created an another page to get the page executed by some query string and get its output. The problem is I can not avoid the delay as simply writing document.write(place.address); will not print anything as it takes a little time to get values so if i set it in setTimeout for delayed output of 1 ms it always return me a value If I request the output from another page using System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd(); I get the source code of the document instead of the desired output can anyone help me out for either avoiding that delay or else delayed the client request ouput so that i get a desired value not the source code The js on default.aspx is <script type="text/javascript"> var geocoder; var address; function initialize() { geocoder = new GClientGeocoder(); var qs=new Querystring(); if(qs.get("lat") && qs.get("lng")) { geocoder.getLocations(new GLatLng(qs.get("lat"),qs.get("lng")),showAddress); } else { document.write("Invalid Access Or Not valid lat long is provided."); } } function getAddress(overlay, latlng) { if (latlng != null) { address = latlng; geocoder.getLocations(latlng, showAddress); } } function showAddress(r) { place = r.Placemark[0]; setTimeout("document.write('" + place.address + "');",1); //document.write(place.address); } </script> and the code on requestClient.aspx is as System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd();

  • WCF web service Data Members defaulting to null

    - by James
    I am new to WCF and created a simple REST service to accept an order object (series of strings from XML file), insert that data into a database, and then return an order object that contains the results. To test the service I created a small web project and send over a stream created from an xml doc. The problem is that even though all of the items in the xml doc get placed into the stream, the service is nullifying some of them when it receives the data. For example lineItemId will have a value but shipment status will show null. I step through the xml creation and verify that all the values are being sent. However, if I clear the datamembers and change the names around, it can work. Any help would be appreciated. This is the interface code [ServiceContract] public interface IShipping { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "/Orders/UpdateOrderStatus/", BodyStyle=WebMessageBodyStyle.Bare)] ReturnOrder UpdateOrderStatus(Order order); } [DataContract] public class Order { [DataMember] public string lineItemId { get; set; } [DataMember] public string shipmentStatus { get; set; } [DataMember] public string trackingNumber { get; set; } [DataMember] public string shipmentDate { get; set; } [DataMember] public string delvryMethod { get; set; } [DataMember] public string shipmentCarrier { get; set; } } [DataContract] public class ReturnOrder { [DataMember(Name = "Result")] public string Result { get; set; } } This is what I'm using to send over an Order object: string lineId = txtLineItem.Text.Trim(); string status = txtDeliveryStatus.Text.Trim(); string TrackingNumber = "1x22-z4r32"; string theMethod = "Ground"; string carrier = "UPS"; string ShipmentDate = "04/27/2010"; XNamespace nsOrders = "http://tempuri.org/order"; XElement myDoc = new XElement(nsOrders + "Order", new XElement(nsOrders + "lineItemId", lineId), new XElement(nsOrders + "shipmentStatus", status), new XElement(nsOrders + "trackingNumber", TrackingNumber), new XElement(nsOrders + "delvryMethod", theMethod), new XElement(nsOrders + "shipmentCarrier", carrier), new XElement(nsOrders + "shipmentDate", ShipmentDate) ); HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:3587/Deposco.svc/wms/Orders/UpdateOrderStatus/"); request.Method = "POST"; request.ContentType = "application/xml"; try { request.ContentLength = myDoc.ToString().Length; StreamWriter sw = new StreamWriter(request.GetRequestStream()); sw.Write(myDoc); sw.Close(); using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { StreamReader reader = new StreamReader(response.GetResponseStream()); string responseString = reader.ReadToEnd(); XDocument.Parse(responseString).Save(@"c:\DeposcoSvcWCF.xml"); } } catch (WebException wEx) { Stream errorStream = ((HttpWebResponse)wEx.Response).GetResponseStream(); string errorMsg = new StreamReader(errorStream).ReadToEnd(); }

  • ActiveMQ 5.2.0 + REST + HTTP POST = java.lang.OutOfMemoryError

    - by Bruce Loth
    First off, I am a newbie when it comes to JMS & ActiveMQ. I have been looking into a messaging solution to serve as middleware for a message producer that will insert XML messages into a queue via HTTP POST. The producer is an existing system written in C++ that cannot be modified (so Java and the C++ API are out). Using the "demo" examples and some trial and error, I have cobbled together a working example of what I want to do (on a windows box). The web.xml I configured in a test directory under "webapps" specifies that the HTTP POST messages received from the producer are to be handled by the MessageServlet. I added a line for the text app in "activemq.xml" ('ow' is the test app dir): I created a test script to "insert" messages into the queue which works well. The problem I am running into is that it as I continue to insert messages via REST/HTTP POST, the memory consumption and thread count used by ActiveMQ continues to rise (It happens when I have timely consumers as well as slow or non-existent consumers). When memory consumption gets around 250MB's and the thread count exceeds 5000 (as shown in windows task manager), ActiveMQ crashes and I see this in the log: Exception in thread "ActiveMQ Transport Initiator: vm://localhost#3564" java.lang.OutOfMemoryError: unable to create new native thread It is as if Jetty is spawning a new thread to handle each HTTP POST and the thread never dies. I did look at this page: http://activemq.apache.org/javalangoutofmemory.html and tried but that didn't fix the problem (although I didn't fully understand the implications of the change either). Does anyone have any ideas? Thanks! Bruce Loth PS - I included the "test message producer" python script below for what it is worth. I created batches of 100 messages and continued to run the script manually from the command line while watching the memory consumption and thread count of ActiveMQ in task manager. def foo(): import httplib, urllib body = "<?xml version='1.0' encoding='UTF-8'?>\n \ <ROOT>\n \ [snip: xml deleted to save space] </ROOT>" headers = {"content-type": "text/xml", "content-length": str(len(body))} conn = httplib.HTTPConnection("127.0.0.1:8161") conn.request("POST", "/ow/message/RDRCP_Inbox?type=queue", body, headers) response = conn.getresponse() print response.status, response.reason data = response.read() conn.close() ## end method definition ## Begin test code count = 0; while(count < 100): # Test with batches of 100 msgs count += 1 foo()

  • Microcontroller to Microcontroller SPI communication

    - by onaclov2000
    Hello again, I was doing some reading and have even gotten a "master" SPI working on my microcontroller. Here is my question, basically if the master wants to initialize a write to the slave we write to the SSPBUF, how do we control what the slave responds with? The datasheet doesn't seem really clear to me the order of events in that case. I.E. Master puts a char into the SSPBUF, this initiates the SPI module to send data to the slave, during the shift, the slave returns a byte. In the slave side, is there something that tells you you have incoming data, and you can write to your SSPBUF first, THEN accept the data? OR Do you have to write to the SSPBUF the first "return value" you want sent back before the master can have an opportunity to initiate a transfer?

  • Unicode in fpc doesn't work

    Hi I'm Romanian and I can't write Unicode in Free Pascal Compiler. I try to write ?,î,â,a,? and it doesn't work. I tried with dos windows changed fonts, tried chcp. I even made a batch file which would do chcp 65001 and start the app. By default when I tried to write these letter I got "?" but when I started it with the batch file it just didn't write anything. I tried AnsiString, UnicodeString, UTF8String and all didn't work. And I think the problem is in the compiler. Does anyone know a solution?

  • WCF - Dynamically Change WebResponseFormat

    - by Brandon
    Is there a way to dynamically change the WebResponseFormat on a method given a parameter passed by the client? I default my WebResponseFormat to XML, but I want to give the client the opportunity to specify a format as JSON or XML and if none is specified, default to XML. Currently I am doing the following: [WebGet(UriTemplate = "objects", BodyStyle = WebMessageBodyStyle.Bare)] [OperationContract] List<SampleObject> GetObjects(); The user can call it via: http://localhost/rest/myservice/objects They then can specify a format by doing: http://localhost/rest/myservice/objects?format=json The problem is that when I try to set the response content type via: WebOperationContext.Current.OutgoingResponse.ContentType = "application/json"; That just returns the XML but the browser attempts to process it like a JSON object instead of serializing the response as JSON. Is this even possible with .NET 3.5 outside of using a Stream as the return value and serializing the response myself? If not, is there a better solution?

  • In-Proc SxS opens for shell extension in managed code?

    - by Jens Granlund
    The recommendation used to be "Do not write in-process shell extensions in managed code." But with .NET Framework 4 and In-Process Side-by-Side the main reason not to write shell extensions in managed code should be resolved. With that said, I have three questions. Is it now okay to write shell extensions in managed code? Which problems, if any might there be with writing shell extensions in managed code? What reasons might there be to write shell extensions in unmanaged code?

  • Rails ActiveResource Associations

    - by brad
    I have some ARes models (see below) that I'm trying to use associations with (which seems to be wholly undocumented and maybe not possible but I thought I'd give it a try) So on my service side, my ActiveRecord object will render something like render :xml => @group.to_xml(:include => :customers) (see generated xml below) The models Group and Customers are HABTM On my ARes side, I'm hoping that it can see the <customers> xml attribute and automatically populate the .customers attribute of that Group object , but the has_many etc methods aren't supported (at least as far as I can tell) So I'm wondering how ARes does it's reflection on the XML to set the attributes of an object. In AR for instance I could create a def customers=(customer_array) and set it myself, but this doesn't seem to work in ARes. One suggestion I found for an "association" is the just have a method def customers Customer.find(:all, :conditions => {:group_id => self.id}) end But this has the disadvantage that it makes a second service call to look up those customers... not cool I'd like my ActiveResource model to see that the customers attribute in the XML and automatically populate my model. Anyone have any experience with this?? # My Services class Customer < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :customer end # My ActiveResource accessors class Customer < ActiveResource::Base; end class Group < ActiveResource::Base; end # XML from /groups/:id?customers=true <group> <domain>some.domain.com</domain> <id type="integer">266</id> <name>Some Name</name> <customers type="array"> <customer> <active type="boolean">true</active> <id type="integer">1</id> <name>Some Name</name> </customer> <customer> <active type="boolean" nil="true"></active> <id type="integer">306</id> <name>Some Other Name</name> </customer> </customers> </group>

  • Creating a child process on Unix systems?

    - by Hakan Svensson
    I'm trying to create a child process in another process. I am writing both the programs in C language. First I write a dummy process which will be the child process. What it is doing is only to write a string on the screen. It works well on its own. Then I write another program which will be the parent process. However, I can't make it happen. I'm trying to use fork and execl functions together, but I fail. I also want the child process does not terminate until the parent process terminates. How should I write the parent process? Thanks.

  • Why a "private static" is not seen in a method?

    - by Roman
    I have a class with the following declaration of the fields: public class Game { private static String outputFileName; .... } I set the value of the outputFileName in the main method of the class. I also have a write method in the class which use the outputFileName. I always call write after main sets value for outputFileName. But write still does not see the value of the outputFileName. It say that it's equal to null. Could anybody, pleas, tell me what I am doing wrong? ADDED As it is requested I post more code: In the main: String outputFileName = userName + "_" + year + "_" + month + "_" + day + "_" + hour + "_" + minute + "_" + second + "_" + millis + ".txt"; f=new File(outputFileName); if(!f.exists()){ try { f.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } System.out.println("IN THE MAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); System.out.println("------>" + outputFileName + "<------"); This line outputs me the name of the file. Than in the write I have: public static void write(String output) { // Open a file for appending. System.out.println("==========>" + outputFileName + "<============"); ...... } And it outputs null.

  • Why isn't the static constructor of the parent class called when invoking a method on a nested class

    - by Ryan Ische
    Given the following code, why isn't the static constructor of "Outer" called after the first line of "Main"? namespace StaticTester { class Program { static void Main( string[] args ) { Outer.Inner.Go(); Console.WriteLine(); Outer.Go(); Console.ReadLine(); } } public static partial class Outer { static Outer() { Console.Write( "In Outer's static constructor\n" ); } public static void Go() { Console.Write( "Outer Go\n" ); } public static class Inner { static Inner() { Console.Write( "In Inner's static constructor\n" ); } public static void Go() { Console.Write( "Inner Go\n" ); } } } }

  • Java + Eclipse: Synchronize stdout and stderr

    - by Martijn Courteaux
    Hi, I use Eclipse. When I have an application like this: write 20 times 'Hello World\n' to stdout write 'ERROR\n' to stderr write 5 times 'Hello World\n' to stdout The output looks many times like this: Hello World Hello World Hello World Hello World Hello World Hello World ... Hello World Hello World Hello World ERROR Is there a way to synchronize these two output streams? Of course without waiting a few milliseconds after the block of 20 times Hello World and waiting a few milliseconds after printing ERROR.
