Hi, I have in my JSP | <!% | @EJB | Library lib; | %> | It works fine when I deploy/redeploy the application. But when I just change the JSP page and reload it in the browser, I got the exception | java.lang.IllegalArgumentException: failed to set value Proxy to jboss.j2ee:ear=books-ear.ear,jar=books-ejb.jar,name=LibraryBean,service=EJB3 implementing [interface cz.root.jboss.library.Library] on field cz.root.jboss.library.Library org.apache.jsp.search_jsp.lib; Reason: ClassLoaders of value and target are not equal | org.jboss.injection.lang.reflect.FieldBeanProperty.set(FieldBeanProperty.java:100) | org.jboss.injection.JndiPropertyInjector.inject(JndiPropertyInjector.java:119) | org.jboss.web.tomcat.service.TomcatInjectionContainer.processInjectors(TomcatInjectionContainer.java:366) | org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:271) | org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:265) | org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:145) | org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) | org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:322) | org.apache.jasper.servlet.JspServlet.service(JspServlet.java:249) | javax.servlet.http.HttpServlet.service(HttpServlet.java:717) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | | My application EAR with EJB JAR and WAR: | books-ear | +-- books-ejb.jar | +-- books-war.war | +-- META-INF | JSP pages are in books-war.war and all EJBs with interfaces are in books-ejb.jar. The WAR has no Java class or any JAR. Do I miss something, e.g. do I have to set classloader? Thanks Andy View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4245769#...
