Hello Everybody, I'm sorry to trouble the list with this question, but I haven't been able to find an answer via google or the archives, so I thought I'd email you guys. Basically, I'm trying to use the Embedded server for jUnit tests on my RESTEasy implementation. I was having trouble just getting a simple example to work, so I searched Google and came across the following post from Rob Williams: "http://www.jroller.com/robwilliams/entry/resteasy_oobe_a_10". In the comments section, Solomon Duskis makes a suggestion: > RESTEasy ClientRequest and EmbeddedServer make this kind of testing even easier. Unfortunately, they're not documented yet... the docs are in progress. > > An example can be found at: http://resteasy.svn.sourceforge.net/viewvc/resteasy/trunk/jaxrs/resteasy-jaxrs/src/test/java/org/jboss/resteasy/test/finegrain/client/ClientResponseTest.java?view=markup > Posted by Solomon Duskis on April 27, 2009 at 07:21 AM PDT # > So I followed his suggested approach. My unit tests run perfectly in my IDE (IntelliJ 10) with no apparent issues. However, when I evoke my test as part of a general maven 3 build, I run into the following problem: > Caused by: java.lang.NullPointerException > at javax.servlet.GenericServlet.log(GenericServlet.java:300) > at javax.servlet.GenericServlet.init(GenericServlet.java:257) > at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.init(HttpServletDispatcher.java:33) > at Acme.Serve.Serve.addServlet(Serve.java:509) > at Acme.Serve.Serve.addServlet(Serve.java:493) > at org.jboss.resteasy.plugins.server.tjws.TJWSServletServer.addServlet(TJWSServletServer.java:57) > at org.jboss.resteasy.plugins.server.tjws.TJWSEmbeddedJaxrsServer.start(TJWSEmbeddedJaxrsServer.java:42) > at org.jboss.resteasy.test.TJWSServletContainer.start(TJWSServletContainer.java:50) > at org.jboss.resteasy.test.TJWSServletContainer.start(TJWSServletContainer.java:40) > at org.jboss.resteasy.test.TJWSServletContainer.start(TJWSServletContainer.java:22) As I mentioned, it's not possible to debug this, as when I step through the downloaded source (man, I love maven), I see no NPE from the IDE perspective. Any ideas as to what could be going on? Am I missing some logging configuration data that IntelliJ somehow magically passes on? I should also mention, that I although my Unit Tests in IntelliJ all run, and come up green, I do see the following logged errors in the output stream: > [Thu Feb 10 11:19:40 CST 2011] MIME map can't be loaded:java.lang.NullPointerException > [Thu Feb 10 11:19:40 CST 2011] Servlet for path '/' already defined and no default will be used. > [Thu Feb 10 11:19:40 CST 2011] TJWS httpd 0.0.0.0 - SimpleAcceptor ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8081] is listening. > [Thu Feb 10 11:19:47 CST 2011] IO error: java.net.SocketException: Broken pipe in processing a request from /127.0.0.1:8081 / java.net.Socket > [Thu Feb 10 11:19:47 CST 2011] Unexpected problem running servlet > java.lang.IllegalStateException: Can not send an error, headers have been already written > at Acme.Serve.Serve$ServeConnection.realSendError(Serve.java:4205) > at Acme.Serve.Serve$ServeConnection.sendError(Serve.java:4183) > at org.jboss.resteasy.plugins.server.servlet.HttpServletResponseWrapper.sendError(HttpServletResponseWrapper.java:71) > at org.jboss.resteasy.core.SynchronousDispatcher.handleFailure(SynchronousDispatcher.java:246) > at org.jboss.resteasy.core.SynchronousDispatcher.handleWriterException(SynchronousDispatcher.java:363) > at org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:202) > at org.jboss.resteasy.core.SynchronousDispatcher.handleWriteResponseException(SynchronousDispatcher.java:187) > at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:488) > at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:119) > at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:207) > at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55) > at org.jboss.resteasy.plugins.server.tjws.TJWSServletDispatcher.service(TJWSServletDispatcher.java:40) > at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) > at Acme.Serve.Serve$ServeConnection.runServlet(Serve.java:2324) > at Acme.Serve.Serve$ServeConnection.parseRequest(Serve.java:2278) > at Acme.Serve.Serve$ServeConnection.run(Serve.java:2052) > at Acme.Utils$ThreadPool$PooledThread.run(Utils.java:1402) > at java.lang.Thread.run(Thread.java:680) I wonder if the null mime map is the issue I'm seeing in Maven? Should I do more to initialize TJWS then: > ResteasyDeployment deployment = EmbeddedContainer.start(); > dispatcher = deployment.getDispatcher(); > dispatcher.getRegistry().addPerRequestResource(PackageService.class); Here's my client connection code: > URL url = new URL(generateBaseUrl() + "/packages"); > connection = (HttpURLConnection)url.openConnection(); Really looking forward to your ideas and suggestions. best wishes, Andrew Waterman |
