  • James Server connection failure exception

    - by John
    Hi, I'm trying to connect Javamail application to James server, but I'm getting javax.mail.MessagingException: Could not connect to SMTP host:localhost, port:4555; nested exception is: java.net.SocketException: Invalid arguent: connect Here's the code, which is creating a little problem for me: import java.security.Security; import java.io.IOException; import java.io.PrintWriter; import java.util.Properties; import javax.mail.*; import javax.mail.internet.*; public class mail { public static void main(String[] argts) { Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); String mailHost = "your.smtp.server"; String to = "blue@localhost"; String from = "red@localhost"; String subject = "jdk"; String body = "Down to wind"; if ((from != null) && (to != null) && (subject != null) && (body != null)) // we have mail to send { try { //Get system properties Properties props = System.getProperties(); props.put("mail.smtp.user", "red"); props.put("mail.smtp.host", "localhost"); props.put("mail.debug", "true"); props.put("mail.smtp.port", 4555); props.put("mail.smtp.socketFactory.port", 4555); props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.socketFactory.fallback", "false"); Session session = Session.getInstance(props,null); Message message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); message.setRecipients(Message.RecipientType.TO, new InternetAddress[] { new InternetAddress(to) }); message.setSubject(subject); message.setContent(body, "text/plain"); message.setText(body); Transport.send(message); System.out.println("<b>Thank you.

  • JLabel animation in JPanel

    - by Trizicus
    After scratching around I found that it's best to implement a custom image component by extending a JLabel. So far that has worked great as I can add multiple "images" (jlabels without the layout breaking. I just have a question that I hope someone can answer for me. I noticed that in order to animate JLabels across the screen I need to setlayout(null); and setbounds of the component and then to animate eventually setlocation(x,y);. Is this a best practice or a terrible way to animate a component? I plan on eventually making an animation class but I don't want to do so and end up having to chuck it. I have included relevant code for a quick review check. import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JPanel; import javax.swing.Timer; public class GraphicsPanel extends JPanel { private Timer timer; private long startTime = 0; private int numFrames = 0; private float fps = 0.0f; private int x = 0; GraphicsPanel() { final Entity ent1 = new Entity(); ent1.setBounds(x, 0, ent1.getWidth(), ent1.getHeight()); add(ent1); //ESSENTIAL setLayout(null); //GAMELOOP timer = new Timer(30, new ActionListener() { public void actionPerformed(ActionEvent e) { getFPS(); incX(); ent1.setLocation(x, 0); repaint(); } }); timer.start(); } public void incX() { x++; } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2 = (Graphics2D) g.create(); g2.setClip(0, 0, getWidth(), getHeight()); g2.setColor(Color.BLACK); g2.drawString("FPS: " + fps, 1, 15); } public void getFPS() { ++numFrames; if (startTime == 0) { startTime = System.currentTimeMillis(); } else { long currentTime = System.currentTimeMillis(); long delta = (currentTime - startTime); if (delta > 1000) { fps = (numFrames * 1000) / delta; numFrames = 0; startTime = currentTime; } } } } Thank you!

  • How do you get Matlab to write the BOM (byte order markers) for UTF-16 text files?

    - by Richard Povinelli
    I am creating UTF16 text files with Matlab, which I am later reading in using Java. In Matlab, I open a file called fileName and write to it as follows: fid = fopen(fileName, 'w','n','UTF16-LE'); fprintf(fid,"Some stuff."); In Java, I can read the text file using the following code: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16LE"); String s = scanner.nextLine(); Here is the hex output: Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 00000000 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 s.o.m.e. .s.t.u.f.f. The above approach works fine. But, I want to be able to write out the file using UTF16 with a BOM to give me more flexibility so that I don't have to worry about big or little endian. In Matlab, I've coded: fid = fopen(fileName, 'w','n','UTF16'); fprintf(fid,"Some stuff."); In Java, I change the code to: FileInputStream fileInputStream = new FileInputStream(fileName); Scanner scanner = new Scanner(fileInputStream, "UTF-16"); String s = scanner.nextLine(); In this case, the string s is garbled, because Matlab is not writing the BOM. I can get the Java code to work just fine if I add the BOM manually. With the added BOM, the following file works fine. Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 00000000 FF FE 73 00 6F 00 6D 00 65 00 20 00 73 00 74 00 75 00 66 00 66 00 ÿþs.o.m.e. .s.t.u.f.f. How can I get Matlab to write out the BOM? I know I could write the BOM out separately, but I'd rather have Matlab do it automatically. Addendum I selected the answer below from Amro because it exactly solves the question I posed. One key discovery for me was the difference between the Unicode Standard and a UTF (Unicode transformation format) (see http://unicode.org/faq/utf_bom.html). The Unicode Standard provides unique identifiers (code points) for characters. UTFs provide mappings of every code point "to a unique byte sequence." Since all but a handful of the characters I am using are in the first 128 code points, I'm going to switch to using UTF-8 as Romeo suggests. UTF-8 is supported by Matlab (The warning shown below won't need to be suppressed.) and Java, and for my application will generate smaller text files. I suppress the Matlab warning Warning: The encoding 'UTF-16LE' is not supported. with warning off MATLAB:iofun:UnsupportedEncoding;

  • Injecting generics with Guice

    - by paradigmatic
    I am trying to migrate a small project, replacing some factories with Guice (it is my first Guice trial). However, I am stuck when trying to inject generics. I managed to extract a small toy example with two classes and a module: import com.google.inject.Inject; public class Console<T> { private final StringOutput<T> out; @Inject public Console(StringOutput<T> out) { this.out = out; } public void print(T t) { System.out.println(out.converter(t)); } } public class StringOutput<T> { public String converter(T t) { return t.toString(); } } import com.google.inject.AbstractModule; import com.google.inject.Guice; import com.google.inject.Injector; import com.google.inject.TypeLiteral; public class MyModule extends AbstractModule { @Override protected void configure() { bind(StringOutput.class); bind(Console.class); } public static void main(String[] args) { Injector injector = Guice.createInjector( new MyModule() ); StringOutput<Integer> out = injector.getInstance(StringOutput.class); System.out.println( out.converter(12) ); Console<Double> cons = injector.getInstance(Console.class); cons.print(123.0); } } When I run this example, all I got is: Exception in thread "main" com.google.inject.CreationException: Guice creation errors: 1) playground.StringOutput<T> cannot be used as a key; It is not fully specified. at playground.MyModule.configure(MyModule.java:15) 1 error at com.google.inject.internal.Errors.throwCreationExceptionIfErrorsExist(Errors.java:354) at com.google.inject.InjectorBuilder.initializeStatically(InjectorBuilder.java:152) at com.google.inject.InjectorBuilder.build(InjectorBuilder.java:105) at com.google.inject.Guice.createInjector(Guice.java:92) I tried looking for the error message, but without finding any useful hints. Further on the Guice FAQ I stumble upon a question about how to inject generics. I tried to add the following binding in the configure method: bind(new TypeLiteral<StringOutput<Double>>() {}).toInstance(new StringOutput<Double>()); But without success (same error message). Can someone explain me the error message and provide me some tips ? Thanks.

  • JVM throws OutOfMemory during gc though there are plenty memory left...

    - by Shu L.
    I have my java application configured to use 5G memory. I got an OutOfMemory out of blue. I inspected the gc log and found plenty of memory left: young generation occupies 4% allocated space, tenure generation occupancy is 5% and perm generation is 43%. I am puzzled why JVM throws an OutOfMemory at the gc time. Does anyone know why this is happening? Your help is greatly appreciated.

  • How to actually use Swing Application Framework?

    - by Joonas Pulakka
    Hello, I'd like to learn how to effectively use Swing Application Framework. Most of the the examples I've found are blog entries that just explain how to great it is to extend SingleFrameApplication and override its startup method, but that's about it. Sun's article is almost two years old, as is the project's own introduction, and there has apparently been some evolution since then. Are there any recent and thorough tutorials/HOWTOs available anywhere? There is JavaDoc of course, but it's hard to get the big picture from there. Any pointers are appreciated. Update: I realized that there's a mailing list archive at the project's site. While somewhat clumsy (compared to StackOverflow ;) it seems to be quite active. Still it's a pity that there are no real tutorials anywhere. The information is scattered here and there. Update 2: Let me clarify - I'm not having trouble using Swing (the widget toolkit) itself, I'm talking about its Application Framework, which is supposed to ease things like application lifecycle (startup, exit and whatever happens between them), action management etc. - that is, things that most Swing applications will need. It's cool to get such framework to be standard part of Java. The only problem is to learn how it's intended to be used. Update 3: For the interested, there was just some discussion at the project's forum regarding the current state and future of JSR 296. Shortly: the current version 1.03 is considered to be quite usable, but the API is not stable and it will change to the final version in Java 7. The package name will also change so Java 7 will not break current applications made on SAF. Update 4: Karsten Lentzsch stated at the above mentioned forum: "I doubt that it can be included in Java 7; and I'll vote against it.". I would rather not question the sincerity of this great guru, and it's certainly wise not to let anything flawed to slip into the core JDK, but frankly it's a strange situation - he is the author of JGoodies Swing Suite which is partly a commercial competitor of JSR 296, and he is sitting in the committee that will decide whether this JSR will be included to standard Java. It was the same thing with JSR 295 Beans Binding which I wrote about earlier. Given the current state of SAF, I think the best solution is to wrap the current implementation into a "homebrew" framework, which can then accommodate possible changes to the existing API.

  • Save File to Sharepoint Server using JAX-WS

    - by Evan Porter
    I'm trying to save a file to a Sharepoint server using JAX-WS. The web service call is reporting a success, but the file doesn't show up. I used this command (from a WinXP) to generate the Java code to make the JAX-WS call: wsimport -keep -extension -Xnocompile http://hostname/sites/teamname/_vti_bin/Copy.asmx?WSDL I get a handle on the web service which I called port using the following: CopySoap port = null; if (userName != null && password != null) { Copy service = new Copy(); port = service.getCopySoap(); ((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, userName); ((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password); } else { throw new Exception("Holy Frijolé! Null userName and/or password!"); } I called the web service using the following: port.copyIntoItems(sourceUrl, destUrlCollection, fields , "Contents of the file".getBytes(), copyIntoItemsResult, copyResultCollection) The sourceUrl and the only url in destUrlCollection equals "hostname/sites/teamname/Tech Docs/Sub Folder". The FieldInformationCollection object named fields contains only one FieldInformation. The FieldInformation object has "HelloWorld.txt" as the value for displayName, internalName and value. The type property is set to FieldType.FILE. The id property is set to (java.util.UUID.randomUUID()).toString(). The call to copyIntoItems returns successfuly; copyIntoItemsResult contains a value of 0 and the only CopyResult object set in copyResultCollection has an error code of "SUCCESS" with a null error message. When I look into the "Tech Docs" library on Sharepoint, in the "Sub Folder" there's no file there. Why wouldn't it tell me what I did wrong? Did I just miss a step? Update (Feb 26th, 2011) I've changed my FieldInformation object's displayName and internalName properties to be "Title" as suggested. Still no joy, but a step in the right direction. After playing around with the urls for a bit, I got these results: With both the sourceUrl and the only destination URL equivalent, with no protocol, I get the SUCCESS response but no actual document appears in the document library. With both of the URLs equivalent but with an "http://" protocol specified, I get an UNKNOWN error with "Object reference not set to an instance of an object." as the message. With the source URL an empty string or null, I get an UNKNOWN error with " Value does not fall within the expected range." as the error message.

  • BindException/Too many file open while using HttpClient under load

    - by Langali
    I have got 1000 dedicated Java threads where each thread polls a corresponding url every one second. public class Poller { public static Node poll(Node node) { GetMethod method = null; try { HttpClient client = new HttpClient(new SimpleHttpConnectionManager(true)); ...... } catch (IOException ex) { ex.printStackTrace(); } finally { method.releaseConnection(); } } } The threads are run every one second: for (int i=0; i <1000; i++) { MyThread thread = threads.get(i) // threads is a static field if(thread.isAlive()) { // If the previous thread is still running, let it run. } else { thread.start(); } } The problem is if I run the job every one second I get random exceptions like these: java.net.BindException: Address already in use INFO httpclient.HttpMethodDirector: I/O exception (java.net.BindException) caught when processing request: Address already in use INFO httpclient.HttpMethodDirector: Retrying request But if I run the job every 2 seconds or more, everything runs fine. I even tried shutting down the instance of SimpleHttpConnectionManager() using shutDown() with no effect. If I do netstat, I see thousands of TCP connections in TIME_WAIT state, which means they are have been closed and are clearing up. So to limit the no of connections, I tried using a single instance of HttpClient and use it like this: public class MyHttpClientFactory { private static MyHttpClientFactory instance = new HttpClientFactory(); private MultiThreadedHttpConnectionManager connectionManager; private HttpClient client; private HttpClientFactory() { init(); } public static HttpClientFactory getInstance() { return instance; } public void init() { connectionManager = new MultiThreadedHttpConnectionManager(); HttpConnectionManagerParams managerParams = new HttpConnectionManagerParams(); managerParams.setMaxTotalConnections(1000); connectionManager.setParams(managerParams); client = new HttpClient(connectionManager); } public HttpClient getHttpClient() { if (client != null) { return client; } else { init(); return client; } } } However after running for exactly 2 hours, it starts throwing 'too many open files' and eventually cannot do anything at all. ERROR java.net.SocketException: Too many open files INFO httpclient.HttpMethodDirector: I/O exception (java.net.SocketException) caught when processing request: Too many open files INFO httpclient.HttpMethodDirector: Retrying request I should be able to increase the no of connections allowed and make it work, but I would just be prolonging the evil. Any idea what is the best practise to use HttpClient in a situation like above? Btw, I am still on HttpClient3.1.

  • ServiceController.Stop() doesn't appear to be stopping anything

    - by peacedog
    My dev box is a Windows 7 (x64) machine. I've got some code (C#, .net 2.0) that in certain circumstances, checks to see if a service is running and then stops it. ServiceController matchedService = //My Service! //If statements and such matchedService.Stop(); matchedService.WaitForStatus(ServiceControllerStatus.Stopped); Now, I can verify MyService is in fact installed and running. I can tell you I am running Visual Studio 2008 as an administrator while debugging. I can also verify that after a couple of If statements, I wind up at the .Stop() and .WaitForStatus() portion of the programming. I do know that if step over the .Stop() call, the service itself just keeps running (looking at it in Services, though it occurs to me perhaps I should grab a better tool for this. I'm sure there's some sysinternals tool that might give me more information). As I step over the .WaitForStatus() call, I basically wind up waiting for the stopped status. . . forever. Well, I let it sit there for over 15 minutes yesterday (twice) and nothing happens. We never make it to the next line of code. It feels exactly like Bowie's Space Oddity (you know the part I am talking about). There's a lotta things about MyService you don't know anything about. Things you wouldn't understand. Things you couldn't. . . let me state this plainly. No services depend on MyService and MyService depends on no other services. Addendum MyOtherService and SonOfMyService both seem to behave correctly at this point in the code. All of these services share the same characteristics (they're our own services we hatched in a secret lab and have no dependencies). Is it possible there is something wrong with the MyService install or something? I do know that if I stop debugging at this point, MyService is still listed as running in Services (even after hitting refresh). If I try to restart it then (or run my application again and get to this point), I get a message about it not being able to accept control messages. After that, the service shows up as stopped and I can start it normally. Why isn't the service being stopped? Is this a quirk of win 7? A failing on my part to understand the ServiceController, or Win Services in general?

  • Two loops speeds drawing in a Jframe

    - by noahn567
    I have a program that requires two classes. The player-Names class, and the Player-Model class. I want the player-Names class to repaint every half second, and the Player-Model class to repaint 60 times per second because i want the movement to be smooth. The problem that i am having is that i want all of this to be done on one J-frame. How would i go about doing this? If you could lead me in the right direction or give me a little example that would be great! Thank you :). for some reason it wont let me post so i'm going to put in some random code import java.awt.Color; import java.awt.Font; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.RenderingHints; import javax.swing.JComponent; import javax.swing.JFrame; public class PlayerNames extends JFrame { static int connectionTimer = 0; static int connectionTimer2 = 0; static int reconnect = 0; static int reconnectValue = 1; static int x = 0; static int reconnectWait = connectionTimer + reconnectValue; private static final long serialVersionUID = 1L; public graph gg = new graph(); public graph g = new graph(); private static GameClient socketClient; private GameServer socketServer; public static void main(int width, int height) { PlayerNames tt = new PlayerNames(); // PlayerGraphics t = new PlayerGraphics(); tt.setSize(width, height); if (Game.ServerOwner == 1) { tt.setTitle("Server: " + Game.username); } else { tt.setTitle("Username: " + Game.username); } tt.setVisible(true); tt.getContentPane().add(tt.gg); tt.getContentPane().add(tt.g); tt.setDefaultCloseOperation(EXIT_ON_CLOSE); tt.setResizable(false); }

  • A case-insensitive related implementation problem

    - by Robert
    Hi All, I am going through a final refinement posted by the client, which needs me to do a case-insesitive query. I will basically walk through how this simple program works. First of all, in my Java class, I did a fairly simple webpage parsing: title=(String)results.get("title"); doc = docBuilder.parse("http://" + server + ":" + port + "/exist/rest/db/wb/xql/media_lookup.xql?" + "&title=" + title); This Java statement references an XQuery file "media_lookup.xql" which is stored on localhost, and the only parameter we are passing is the string "title". Secondly, let's take at look at that XQuery file: $title := request:get-parameter('title',""), $mediaNodes := doc('/db/wb/portfolio/media_data.xml'), $query := $mediaNodes//media[contains(title,$title)], Then it will evaluate that query. This XQuery will get the "title" parameter that are passes from our Java class, and query the "media_data" xml file stored in the database, which contains a bunch of media nodes with a 'title' element node. As you may expect, this simple query will just match those media nodes whose 'title' element contains a substring of what the value of string 'title' is. So if our 'title' is "Chi", it will return media nodes whose title may be "Chicago" or "Chicken". The refinment request posted by the client is that there should be NO case-sensitivity. The very intuitive way is to modify the XQuery statement by using a lower-case funtion in it, like: $query := $mediaNodes//media[contains(lower-case(title/text(),lower-case($title))], However, the question comes: this modified query will run my machine into memory overflow. Since my "media_data.xml" is quite huge and contains thouands of millions of media nodes, I assume the lower-case() function will run on each of the entries, thus causing the machine to crash. I've talked with some experienced XQuery programmer, and they think I should use an index to solve this problem, and I will definitely research into that. But before that, I am just posting this problem here to get other ideas or any suggestions, do you think any other way may help? for example, could I tweak the Java parse statement to realize the case-insensitivity? Since I think I saw some people did some string concatination by using "contains." in Java before passing it to the server. Any idea or help is welcomed, thanks in advance.

  • JPA - Can I create an Entity class, using an @DiscriminatorValue, that doesn't have its own table?

    - by DaveyDaveDave
    Hi - this is potentially a bit complex, so I'll do my best to describe my situation - it's also my first post here, so please forgive formatting mistakes, etc! I'm using JPA with joined inheritance and a database structure that looks like: ACTION --------- ACTION_ID ACTION_MAPPING_ID ACTION_TYPE DELIVERY_CHANNEL_ACTION -------------------------- ACTION_ID CHANNEL_ID OVERRIDE_ADDRESS_ACTION -------------------------- ACTION_ID (various fields specific to this action type) So, in plain English, I have multiple different types of action, all share an ACTION_MAPPING, which is referenced from the 'parent' ACTION table. DELIVERY_CHANNEL_ACTION and OVERRIDE_ADDRESS_ACTION both have extra, supplementary data of their own, and are mapped to ACTION with a FK. Real-world, I also have a 'suppress' action, but this doesn't have any supplementary data of its own, so it doesn't have a corresponding table - all it needs is an ACTION_MAPPING, which is stored in the ACTION table. Hopefully you're with me so far... I'm creating a new project from scratch, so am pretty flexible in what I can do, but obviously would like to get it right from the outset! My current implementation, which works, has three entities loosely defined as follows: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) @DiscriminatorValue("SUPPRESS") public class Action @Entity @Table(name="DELIVERY_CHANNEL_ACTION") @DiscriminatorValue("DELIVERY_CHANNEL") public class DeliveryChannelAction extends Action @Entity @Table(name="OVERRIDE_ADDRESS_ACTION") @DiscriminatorValue("OVERRIDE_ADDRESS") public class OverrideAddressAction extends Action That is - I have a concrete base class, Action, with a Joined inheritance strategy. DeliveryChannelAction and OverrideAddressAction both extend Action. What feels wrong here though, is that my Action class is the base class for these two actions, but also forms the concrete implementation for the suppress action. For the time being this works, but at some point more actions are likely to be added, and there's every chance that some of them will, like SUPPRESS, have no supplementary data, which will start to get difficult! So... what I would like to do, in the object model world, is to have Action be abstract, and create a SuppressAction class, which is empty apart from having a @DiscriminatorValue("SUPPRESS"). I've tried doing exactly what is described above, so, changing Action to: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) public abstract class Action and creating: @DiscriminatorValue("SUPPRESS") public class SuppressAction extends Action but no luck - it seems to work fine for DeliveryChannelAction and OverrideAddressAction, but when I try to create a SuppressAction and persist it, I get: java.lang.IllegalArgumentException: Object: com.mypackage.SuppressAction[actionId=null] is not a known entity type. at org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.registerNewObjectForPersist(UnitOfWorkImpl.java:4147) at org.eclipse.persistence.internal.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:368) at com.mypackage.test.util.EntityTestUtil.createSuppressAction(EntityTestUtil.java:672) at com.mypackage.entities.ActionTest.testCRUDAction(ActionTest.java:27) which I assume is down to the fact that SuppressAction isn't registered as an entity, but I don't know how I can do that, given that it doesn't have an associated table. Any pointers, either complete answers or hints for things to Google (I'm out of ideas!), most welcome :) EDIT: to correct my stacktrace.

  • Painted JPanel won't show up in JFrame

    - by javawarrior
    When I run my code, I expect to see a JPanel in my JFrame, but nothing shows up. I had a button in the frame, and it shows up. But the JPanel doesn't show up, I even colored it in red. Here is the code for my JPanel: import java.awt.*; import javax.swing.JPanel; public class graphic extends JPanel { private static final long serialVersionUID = -3458717449092499931L; public Game game; public graphic(Game game){ this.game = game; this.setPreferredSize(new Dimension(400,400)); this.setBackground(Color.RED); } public void paintComponent(Graphics g){ for (Line l:game.mirrors){ g.setColor(Color.BLACK); g.drawLine(l.start.x, l.start.y, l.end.x, l.end.y); } } } And my JFrame code: import java.awt.Container; import java.awt.event.*; import java.util.Timer; import java.util.TimerTask; import javax.swing.*; public class Viewer implements ActionListener { public JFrame frame; public JButton drawShoot; public boolean draw; public Game game; public graphic graphic; public TimerTask timert; public Timer timer; public Viewer(){ draw = true; game = new Game(); } public static void main(String args[]){ Viewer v = new Viewer(); v.setup(); } public void setup(){ frame = new JFrame("Laser Stimulator"); drawShoot = new JButton("Edit Mode"); graphic = new graphic(game); graphic.repaint(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setBounds(300, 300, 600, 600); Container contentPane = frame.getContentPane(); SpringLayout layout = new SpringLayout(); contentPane.setLayout(layout); drawShoot.addActionListener(this); timert = new TimerTask() { @Override public void run() { } }; timer =new Timer(); timer.scheduleAtFixedRate(timert, 0, 1000/30); contentPane.add(graphic); layout.putConstraint(SpringLayout.NORTH, graphic, 0, SpringLayout.NORTH, contentPane); layout.putConstraint(SpringLayout.WEST, graphic, 0, SpringLayout.WEST, contentPane); frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { if (e.getSource()==drawShoot){ draw = !draw; drawShoot.setText((draw)?"Edit Mode":"Shoot Mode"); } } }

  • HTTP Bad Request error when requesting a WCF service contract

    - by Enrico Campidoglio
    I have a WCF service with the following configuration: <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="MetadataEnabled"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceMetadata httpGetEnabled="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="MetadataEnabled" name="MyNamespace.MyService"> <endpoint name="BasicHttp" address="" binding="basicHttpBinding" contract="MyNamespace.IMyServiceContract" /> <endpoint name="MetadataHttp" address="contract" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost/myservice" /> </baseAddresses> </host> </service> </services> </system.serviceModel> When hosting the service in the WcfSvcHost.exe process, if I browse to the URL: http://localhost/myservice/contract where the service metadata is available I get an HTTP 400 Bad Request error. By inspecting the WCF logs I found out that an System.Xml.XmlException exception is being thrown with the message: "The body of the message cannot be read because it is empty."Here is an extract of the log file: <Exception> <ExceptionType> System.ServiceModel.ProtocolException, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 </ExceptionType> <Message>There is a problem with the XML that was received from the network.

At this point, I can also remove the "MetadataHttp" metadata endpoint completely, and it wouldn't make any difference. I'm using .NET 3.5 SP1. Does anyone have an idea of what could be wrong here?

  • Calling a WCF service from Java

    - by Ian Kemp
    As the title says, I need to get some Java 1.5 code to call a WCF web service. I've downloaded and used Metro to generate Java proxy classes, but they aren't generating what I expect, and I believe this is because of the WSDL that the WCF service generates. My WCF classes look like this (full code omitted for brevity): public class TestService : IService { public TestResponse DoTest(TestRequest request) { TestResponse response = new TestResponse(); // actual testing code... response.Result = ResponseResult.Success; return response; } } public class TestResponse : ResponseMessage { public bool TestSucceeded { get; set; } } public class ResponseMessage { public ResponseResult Result { get; set; } public string ResponseDesc { get; set; } public Guid ErrorIdentifier { get; set; } } public enum ResponseResult { Success, Error, Empty, } and the resulting WSDL (when I browse to http://localhost/TestService?wsdl=wsdl0) looks like this: <xsd:element name="TestResponse"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="TestSucceeded" type="xsd:boolean" /> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name="ErrorIdentifier" type="q1:guid" xmlns:q1="http://schemas.microsoft.com/2003/10/Serialization/" /> <xsd:simpleType name="ResponseResult"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="Error" /> <xsd:enumeration value="Success" /> <xsd:enumeration value="EmptyResult" /> </xsd:restriction> </xsd:simpleType> <xsd:element name="ResponseResult" nillable="true" type="tns:ResponseResult" /> <xsd:element name="Result" type="tns:ResponseResult" /> <xsd:element name="ResultDesc" nillable="true" type="xsd:string" /> ... <xs:element name="guid" nillable="true" type="tns:guid" /> <xs:simpleType name="guid"> <xs:restriction base="xs:string"> <xs:pattern value="[\da-fA-F]{8}-[\da-fA-F]{4}-[\da-fA-F]{4}-[\da-fA-F]{4}-[\da-fA-F]{12}" /> </xs:restriction> </xs:simpleType> Immediately I see an issue with this WSDL: TestResponse does not contain the properties inherited from ResponseMessage. Since this service has always worked in Visual Studio I've never questioned this before, but maybe that could be causing my problem? Anyhow, when I run Metro's wsimport.bat on the service the following error message is generated: [WARNING] src-resolve.4.2: Error resolving component 'q1:guid' and the outputted Java version of TestResponse lacks any of the properties from ResponseMessage. I hacked the WSDL a bit and changed ErrorIdentifier to be typed as xsd:string, which makes the message about resolving the GUID type go away, but I still don't get any of ResponseMessage's properties. Finally, I altered the WSDL to include the 3 properties from ResponseMessage in TestResponse, and of course the end result is that the generated .java file contains them. However, when I actually call the WCF service from Java, those 3 properties are always null. Any advice, apart from writing the proxy classes myself?

  • jquery with ASP.NET MVC - calling ajax enabled web service

    - by dcp
    This is a bit of a continuation of a previous question. Now I'm trying to make a call to an AJAX enabled web service which I have defined within the ASP.NET MVC application (i.e. the MovieService.svc). But the service is never being called in my getMovies javascript function. This same technique of calling the AJAX web service works ok if I try it in a non ASP.NET MVC application, so it makes me wonder if maybe the ASP MVC routes are interfering with things somehow when it tries to make the AJAX web service call. Do you have any idea why my web service isn't getting called? Code below. <script src="<%= ResolveClientUrl("~/scripts/jquery-1.4.2.min.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/grid.locale-en.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/jquery-ui-1.8.1.custom.min.js") %>" type="text/javascript"></script> <script src="<%= ResolveClientUrl("~/scripts/jquery.jqGrid.min.js") %>" type="text/javascript"></script> <script type="text/javascript"> var lastsel2; function successFunction(jsondata) { debugger var thegrid = jQuery("#editgrid"); for (var i = 0; i < jsondata.d.length; i++) { thegrid.addRowData(i + 1, jsondata.d[i]); } } function getMovies() { debugger // ***** the MovieService#GetMovies method never gets called $.ajax({ url: 'MovieService.svc/GetMovies', data: "{}", // For empty input data use "{}", dataType: "json", type: "GET", contentType: "application/json; charset=utf-8", success: successFunction }); } jQuery(document).ready(function() { jQuery("#editgrid").jqGrid({ datatype: getMovies, colNames: ['id', 'Movie Name', 'Directed By', 'Release Date', 'IMDB Rating', 'Plot', 'ImageURL'], colModel: [ { name: 'id', index: 'Id', width: 55, sortable: false, hidden: true, editable: false, editoptions: { readonly: true, size: 10} }, { name: 'Movie Name', index: 'Name', width: 250, editable: true, editoptions: { size: 10} }, { name: 'Directed By', index: 'Director', width: 250, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Release Date', index: 'ReleaseDate', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'IMDB Rating', index: 'IMDBUserRating', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Plot', index: 'Plot', width: 150, hidden: false, editable: true, editoptions: { size: 30} }, { name: 'ImageURL', index: 'ImageURL', width: 55, hidden: true, editable: false, editoptions: { readonly: true, size: 10} } ], pager: jQuery('#pager'), rowNum: 5, rowList: [5, 10, 20], sortname: 'id', sortorder: "desc", height: '100%', width: '100%', viewrecords: true, imgpath: '/Content/jqGridCss/redmond/images', caption: 'Movies from 2008', editurl: '/Home/EditMovieData/', caption: 'Movie List' }); $("#bedata").click(function() { var gr = jQuery("#editgrid").jqGrid('getGridParam', 'selrow'); if (gr != null) jQuery("#editgrid").jqGrid('editGridRow', gr, { height: 280, reloadAfterSubmit: false }); else alert("Hey dork, please select a row"); }); }); </script> <h2> <%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website"> http://asp.net/mvc</a>. </p> <table id="editgrid"> </table> <div id="pager" style="text-align: center;"> </div> <input type="button" id="bedata" value="Edit Selected" /> Here's my RegisterRoutes code: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("*MovieService.svc*"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } Here's what my MovieService class looks like: namespace jQueryMVC { [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { // Add [WebGet] attribute to use HTTP GET [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json)] public IList<Movie> GetMovies() { return Persistence.GetMovies(); } } }

  • Using jQuery to call a web service

    - by Matt
    I have created a web service which takes a username and password as parameters and returns a list of children in JSON (the user is a Social Worker). The web service is hosted locally with IIS7. I am attempting to access the web service using javascript/jquery because it will eventually need to run as a mobile app. I'm not really experienced with web services, or javascript for that matter, but the following two links seemed to point me in the right direction: http://williamsportwebdeveloper.com/cgi/wp/?p=494 http://encosia.com/using-jquery-to-consume-aspnet-json-web-services/ This is my html page: <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="TestWebService.aspx.cs" Inherits="Sponsor_A_Child.TestWebService" %> <asp:Content ID="Content1" ContentPlaceHolderID="stylesPlaceHolder" runat="server"> <script type="text/javascript" src="Scripts/jquery-1.7.1.js"> $(document).ready(function () { }); function LoginClientClick() { $("#query_results").empty(); $("#query_results").append('<table id="ResultsTable" class="ChildrenTable"><tr><th>Child_ID</th><th>Child_Name</th><th>Child_Surname</th></tr>'); $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://localhost/PhoneWebServices/GetChildren.asmx/GetMyChildren", data: '{ "email" : "' + $("#EmailBox").val() + '", "password": "' + $("#PasswordBox").val() + '" }', dataType: "json", success: function (msg) { var c = eval(msg.d); alert("" + c); for (var i in c) { $("#ResultsTable tr:last").after("<tr><td>" + c[i][0] + "</td><td>" + c[i][1] + "</td><td>" + c[i][2] + "</td></tr>"); } } }); } </script> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="contentPlaceHolder" runat="server"> <div id="LoginDiv"> Email: <input id="EmailBox" type="text" /><br /> Password: <input id="PasswordBox" type="password" /><br /> <input id="LoginButton" type="button" value="Submit" onclick="LoginClientClick()" /> </div> <div id="query_results"> </div> </asp:Content> And this is my web service code: [WebMethod (Description="Returns the list of children for whom the social worker is responsible.")] public String GetMyChildren(String email,String password) { DataSet MyChildren=new DataSet(); int ID=SocialWorkerLogin(email, password); if (ID > 0) { MyChildren = FillChildrenTable(ID); } MyChildren.DataSetName = "My Children"; //To prevent 'DataTable name not set' error string[][] JaggedArray = new string[MyChildren.Tables[0].Rows.Count][]; int i = 0; foreach (DataRow rs in MyChildren.Tables[0].Rows) { JaggedArray[i] = new string[] { rs["Child_ID"].ToString(), rs["Child_Name"].ToString(), rs["Child_Surname"].ToString() }; i = i + 1; } // Return JSON data JavaScriptSerializer js = new JavaScriptSerializer(); string strJSON = js.Serialize(JaggedArray); return strJSON; } I followed the examples in the provided links, but when I press submit, only the table headers appear but not the list of children. When I test the web service on it's own though, it does return a JSON string so that part seems to be working. Any help is greatly appreciated :)

  • Web service client receiving generic FaultException rather than FaultException<T>

    - by Junto
    I am connecting to a Java Axis2 web service using a .NET web service client. The client itself targets the .NET 3.5 framework. The application that wraps the client DLL is 2.0. I'm not sure if that has any bearing. I have been given the WSDL and XSDs by email. From those I have built my proxy class using svcutil. Although I am able to successfully send messages, I am unable to pick up the correct faults when something goes wrong. In the example below, errors are always being picked up by the generic FaultException. catch (FaultException<InvoiceErrorType> fex) { OnLog(enLogLevel.ERROR, fex.Detail.ErrorDescription); } catch (FaultException gfex) { OnLog(enLogLevel.ERROR, gfex.Message); } The proxy client appears to have the appropriate attributes for the FaultContract: // CODEGEN: Generating message contract since the operation SendInvoiceProvider_Prod is neither RPC nor document wrapped. [OperationContractAttribute(Action = "https://private/SendInvoiceProvider", ReplyAction = "*")] [FaultContractAttribute(typeof(InvoiceErrorType), Action = "https://private/SendInvoiceProvider", Name = "InvoiceError", Namespace = "urn:company:schema:entities:base")] [XmlSerializerFormatAttribute(SupportFaults = true)] [ServiceKnownTypeAttribute(typeof(ItemDetail))] [ServiceKnownTypeAttribute(typeof(Supplier))] OutboundComponent.SendInvoiceProviderResponse SendInvoiceProvider_Prod(OutboundComponent.SendInvoiceProvider_Request request); I have enabled tracing and I can see the content of the fault coming back, but .NET is not recognizing it as an InvoiceError. The SOAP fault in full is: <soapenv:Fault> <faultcode xmlns="">soapenv:Client</faultcode> <faultstring xmlns="">Message found to be invalid</faultstring> <faultactor xmlns="">urn:SendInvoiceProvider</faultactor> <detail xmlns=""> <InvoiceError xmlns="urn:company:schema:entities:common:invoiceerror:v01"> <ErrorID>100040</ErrorID> <ErrorType>UNEXPECTED</ErrorType> <ErrorDescription>&lt;![CDATA[&lt;error xmlns="urn:company:schema:errordetail:v01"&gt;&lt;errorCode&gt;1000&lt;/errorCode&gt;&lt;highestSeverity&gt;8&lt;/highestSeverity&gt;&lt;errorDetails count="1"&gt;&lt;errorDetail&gt;&lt;errorType&gt;1&lt;/errorType&gt;&lt;errorSeverity&gt;8&lt;/errorSeverity&gt;&lt;errorDescription&gt;cvc-complex-type.2.4.a: Invalid content was found starting with element 'CompanyName'. One of '{"urn:company:schema:sendinvoice:rq:v01":RoleType}' is expected.&lt;/errorDescription&gt;&lt;errorNamespace&gt;urn:company:schema:sendinvoice:rq:v01&lt;/errorNamespace&gt;&lt;errorNode&gt;CompanyName&lt;/errorNode&gt;&lt;errorLine&gt;1&lt;/errorLine&gt;&lt;errorColumn&gt;2556&lt;/errorColumn&gt;&lt;errorXPath/&gt;&lt;errorSource/&gt;&lt;/errorDetail&gt;&lt;/errorDetails&gt;&lt;/error&gt;]]&gt;</ErrorDescription> <TimeStamp>2010-05-04T21:12:10Z</TimeStamp> </InvoiceError> </detail> </soapenv:Fault> I have noticed the namespace defined on the error: <InvoiceError xmlns="urn:company:schema:entities:common:invoiceerror:v01"> This is nowhere to be seen in the generated proxy class, nor in the WSDLs. The interface WSDL defines the error schema namespace as such: <xs:import namespace="urn:company:schema:entities:base" schemaLocation="InvoiceError.xsd"/> Could this be the reason why the .NET client is not able to parse the typed Fault Exception correctly? I have no control over the web service itself. I see no reason why .NET can't talk to a Java Axis2 web service. This user had a similar issue, but the reason for his problem cannot be the same as mine, since I can see the fault detail in the trace: http://stackoverflow.com/questions/864800/does-wcf-faultexceptiont-support-interop-with-a-java-web-service-fault Any help would be gratefully received.
