List<NameValuePair> formparams = new ArrayList<NameValuePair>(); formparams.add(new BasicNameValuePair("employee", "thomas")); formparams.add(new BasicNameValuePair("reason", "test")); HttpPost httpPost = new HttpPost(" http:// http://"; + "localhost:8888" + "/gwt-console-server/rs/form/process/" + "com.sample.evaluation" + "/complete"); InputStreamReader inputStreamReader = null; BufferedReader bufferedReader = null; try { UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "UTF-8");// UrlEncodedFormEntity(formparams, // "multipart/form-data"); httpPost.setEntity(entity); HttpResponse response = httpClient.execute(httpPost); InputStream inputStream = response.getEntity().getContent(); inputStreamReader = new InputStreamReader(inputStream); bufferedReader = new BufferedReader(inputStreamReader); StringBuilder stringBuilder = new StringBuilder(); String line = bufferedReader.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReader.readLine(); } responseString = stringBuilder.toString(); } catch (Exception e) { throw new RuntimeException(e); } finally { if (inputStreamReader != null) { try { inputStreamReader.close(); } catch (Exception e) { throw new RuntimeException(e); } } if (bufferedReader != null) { try { bufferedReader.close(); } catch (Exception e) { throw new RuntimeException(e); } } } return responseString; } and I got this error <html><head><title>JBoss Web/7.0.1.Final - Error report</title><style><!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}--></style> </head><body><h1>HTTP Status 500 - </h1><HR size="1" noshade="noshade"><p><b>type</b> Exception report</p><p><b>message</b> <u></u></p><p><b>description</b> <u>The server encountered an internal error () that prevented it from fulfilling this request.</u></p><p><b>exception</b> <pre>org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Timeout : unable to retrieve Task org.jboss.resteasy.core.SynchronousDispatcher.unwrapException(SynchronousDispatcher.java:345) org.jboss.resteasy.core.SynchronousDispatcher.handleApplicationException(SynchronousDispatcher.java:321) org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:214) org.jboss.resteasy.core.SynchronousDispatcher.handleInvokerException(SynchronousDispatcher.java:190) org.jboss.resteasy.core.SynchronousDispatcher.getResponse(SynchronousDispatcher.java:534) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:496) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:119) org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:208) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50) javax.servlet.http.HttpServlet.service(HttpServlet.java:847) org.jboss.bpm.console.server.util.GWTJsonFilter.doFilter(GWTJsonFilter.java:59)</pre></p><p><b>root cause</b> <pre>java.lang.RuntimeException: Timeout : unable to retrieve Task org.jbpm.task.service.responsehandlers.BlockingGetTaskResponseHandler.getTask(BlockingGetTaskResponseHandler.java:41) org.jbpm.task.service.SyncTaskServiceWrapper.getTask(SyncTaskServiceWrapper.java:369) org.jbpm.integration.console.forms.TaskFormDispatcher.provideForm(TaskFormDispatcher.java:64) org.jbpm.integration.console.forms.FormDispatcherComposite.provideForm(FormDispatcherComposite.java:50) org.jboss.bpm.console.server.FormProcessingFacade.provideForm(FormProcessingFacade.java:205) org.jboss.bpm.console.server.FormProcessingFacade.renderTaskUI(FormProcessingFacade.java:127) sun.reflect.GeneratedMethodAccessor101.invoke(Unknown Source) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:597) org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:140) org.jboss.resteasy.core.ResourceMethod.invokeOnTarget(ResourceMethod.java:255) org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:220) org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:209) org.jboss.resteasy.core.SynchronousDispatcher.getResponse(SynchronousDispatcher.java:519) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:496) org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:119) org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:208) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55) org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50) javax.servlet.http.HttpServlet.service(HttpServlet.java:847) org.jboss.bpm.console.server.util.GWTJsonFilter.doFilter(GWTJsonFilter.java:59)</pre></p><p><b>note</b> <u>The full stack trace of the root cause is available in the JBoss Web/7.0.1.Final logs.</u></p><HR size="1" noshade="noshade"><h3>JBoss Web/7.0.1.Final</h3></body></html> -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/752796#752796] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
