Csaba K [https://community.jboss.org/people/chabee] created the discussion "Adding library to the console-server (can not resolve java.util.Random)" To view the discussion, visit: https://community.jboss.org/message/806352#806352 -------------------------------------------------------------- Hello! I created a bpmn2 flow and it runs fine in eclipse. As I commit it to the Guvnor Server, I build it, and I try to run it from jbpm-console it fails. I use in the flow a Random generator (java.util.Random) and this is the problem. So I think the console-server does not contain a jar file, which contains java.util.Random class. My question is: How can I add lib files to the console server? The error message in the server.log: javax.ws.rs.WebApplicationException: org.jbpm.workflow.instance.WorkflowRuntimeException: [hu.bme.mit.businessprocess.bpmn.business:12 - VariableSet:4] -- unable to execute Action: [Error: could not resolve class: Random from [Module "deployment.jbpm-gwt-console-server.war:main" from Service Module Loader]] [Near : {... dom generator = new Random(); ....}]                                  ^ [Line: 1, Column: 34]     at org.jboss.bpm.console.server.ProcessMgmtFacade.newInstance(ProcessMgmtFacade.java:214) [classes:]     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [:1.6.0_24]     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) [:1.6.0_24]     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [:1.6.0_24]     at java.lang.reflect.Method.invoke(Method.java:616) [:1.6.0_24]     at org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:140) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.ResourceMethod.invokeOnTarget(ResourceMethod.java:255) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:220) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:209) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.SynchronousDispatcher.getResponse(SynchronousDispatcher.java:519) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:496) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:119) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:208) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55) [resteasy-jaxrs-2.2.1.GA.jar:]     at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50) [resteasy-jaxrs-2.2.1.GA.jar:]     at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) [jboss-servlet-api_3.0_spec-1.0.0.Final.jar:1.0.0.Final]     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:329) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.jboss.bpm.console.server.util.GWTJsonFilter.doFilter(GWTJsonFilter.java:59) [classes:]     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:280) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:275) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:161) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:139) [jboss-as-web-7.0.2.Final.jar:7.0.2.Final]     at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:480) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.jboss.as.web.NamingValve.invoke(NamingValve.java:57) [jboss-as-web-7.0.2.Final.jar:7.0.2.Final]     at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:154) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:362) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:667) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:952) [jbossweb-7.0.1.Final.jar:7.0.2.Final]     at java.lang.Thread.run(Thread.java:679) [:1.6.0_24] Thank you for your help!
