    Problems with contexts not being active

    Andrew Watters Newbie

      I'm trying to invoke a SSB from a servlet filter using Seam 1.2.1 deployed on JBoss 4.2.1.

      From the filter I'm calling the SSB using Component.getInstance("myService", true). At first this failed on calling Component.getInstance throwing a IllegalStateException with the message "No application context active". I 'discovered' org.jboss.seam.web.ContextFilter and added it to my web.xml. The SSB is now called without problems. However, when the request returns to the ContextFilter it fails with another IllegalStateException with the message "No active event context".

      java.lang.IllegalStateException: No active event context
      at org.jboss.seam.core.Manager.instance(Manager.java:267)
      at org.jboss.seam.web.ContextFilter.doFilter(ContextFilter.java:58)

      Help please!

            Sorry to steal the thread but I'm having the same issue so I'll post mine! :-)

            First a bit of background.. I did a quick app using the generate-entities and put a web service in front of some of the entityHome's. After some hair pulling it worked great. Now I moved the app to an integration machine. Same version of jboss and seam (4.2.0GA and 2.0.0GA) and now I'm getting the IllegalStateException regarding the lack of an active context when I call the webservice. Its really weird since I didn't change anything (I actually zipped up the deployed app from my desktop and unzipped on the server to make sure it was the same..) Anyways.. Here's my web.xml and component.xml... Any help would be greatly appreciated...

              I don't see how its the same problem, you aren't using the context filter.

                I have just the same problem with ContextFilter as akwatters. I use seam 2.0.GA and Jboss 4.2.2.

                I want to get access to seam component from my servlet (catalogDispatcher), so I add org.jboss.seam.web.ContextFilter before my servlet and call

                Component.getInstance("myComponentName");
                


                Everything works fine, but when my servlet ends doGet function execution - error appears:

                  Please attach a runnable example with steps to reproduce to a new jira issue.

                    I actually localize the problem. Error is show if I try to redirect from my servlet to seam page. If I do redirect to simple (not seam) JSP page - everything is ok.

                    request.getRequestDispatcher("/seam/index.xhtml").forward(request, httpServletResponse);
                    



                    I don`t know how to attach a file in this forum, so I`ll describe my steps to create a example application.

                    I took a seam example Blog application (it comes as example application with JBoss Seam sources) add my test servlet (TestServlet.java)

                    package actions;
                    
                    import javax.servlet.http.HttpServlet;
                    import javax.servlet.http.HttpServletRequest;
                    import javax.servlet.http.HttpServletResponse;
                    import javax.servlet.ServletException;
                    import java.io.IOException;
                    import org.jboss.seam.Component;
                    
                    public class TestServlet extends HttpServlet {
                     protected void doGet(HttpServletRequest request, HttpServletResponse httpServletResponse) throws ServletException, IOException {
                     TestAction testAction = (TestAction) Component.getInstance("testAction");
                    
                     request.getRequestDispatcher("/seam/index.xhtml").forward(request, httpServletResponse);
                     }
                    }
                    


                    add TestAction.java

                    package actions;
                    
                    import org.jboss.seam.ScopeType;
                    import org.jboss.seam.annotations.Factory;
                    import org.jboss.seam.annotations.In;
                    import org.jboss.seam.annotations.Name;
                    import org.jboss.seam.annotations.Scope;
                    
                    @Scope(ScopeType.EVENT)
                    @Name("testAction")
                    public class TestAction {
                     public String sayHi() {
                     return "hallo, dude";
                     }
                    }
                    


                    and modify web.xml file:
                     <servlet>
                     <servlet-name>TestServlet</servlet-name>
                     <servlet-class>actions.TestServlet</servlet-class>
                     </servlet>
                    
                     <servlet-mapping>
                     <servlet-name>TestServlet</servlet-name>
                     <url-pattern>/testservlet/*</url-pattern>
                     </servlet-mapping>
                    
                     <filter>
                     <filter-name>ContextFilter</filter-name>
                     <filter-class>org.jboss.seam.web.ContextFilter</filter-class>
                     </filter>
                    
                     <filter-mapping>
                     <filter-name>ContextFilter</filter-name>
                     <url-pattern>/testservlet/*</url-pattern>
                     </filter-mapping>

                      For next generations: in my case i found workaround - not use

                      Component.getInstance


                      but use JNDI lookup instead (in my case I create Stateless SB).
