Re: [Resteasy-users] TJWS - 2.1.0.GA: NPE while using EmbeddedServer from Maven

Thanks for your help Michael. This looks to be a maven dependency configuration issue. I narrowed it down to what looks like a classpath conflict between TJWS and Jetty (another test in the project I've been working on uses Jetty). Once that is removed, TJWS tests can run. Also TJWS looks to need a declared version of the Servlet API to work properly. I'm still seeing the following issue, when I scope a versioned Servlet API to "provided", although the tests now run and pass: > 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:820) > 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) Are these known issues, I wonder? best wishes, Andrew On Feb 10, 2011, at 11:28 AM, awaterma wrote: > 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".

My unit tests run perfectly in my IDE (IntelliJ 10) with no apparent issues.
