I need to change the designer context root to support multiple instances of guvnor and thereby designer on the same server. I did by changing the following files guvnor.war/WEB-INF/jboss-web.xml - Change context root guvnor.war/WEB-INF/beans.xml - Configure jcr repository location guvnor.war/classes/preferences.properties - Configure designer context root designer.war/WEB-INF/jboss-web.xml - Change context root designer.war/profiles/jbpm.xml - Configure guvnor context root The default one does come up fine, but the other fails to load the designer with the following exception. 12:27:36,369 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/designer01].[PluginServiceServlet]] (http--127.0.0.1-8 ervlet.service() for servlet PluginServiceServlet threw exception: java.lang.IllegalArgumentException: No plugin by the name of plugins at org.jbpm.designer.web.plugin.impl.PluginServiceServlet.retrievePluginContents(PluginServiceServlet.java:93) [classes:] at org.jbpm.designer.web.plugin.impl.PluginServiceServlet.doGet(PluginServiceServlet.java:71) [classes:] at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) [jboss-servlet-api_3.0_spec-1.0.0.Final.jar:1.0.0.Final] 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-7.0.13.Final.jar:] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.13.Final.jar:] at org.jbpm.designer.web.filter.impl.PluggableFilter.doFilter(PluggableFilter.java:70) [classes:] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:280) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:275) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:161) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:153) [jboss-as-web-7.1.1.Fina 1.1.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:155) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_30] -- View this message in context: http://drools.46999.n3.nabble.com/service-for-servlet-PluginServiceServle...
