Getting a Stateless component from a servlet does not work anymore under Seam 2.1.0.CR1

[jkronegg]

Hi guys,

Under Seam 2.1.0 snapshot #306 (2008.09.12), I was accessing a Stateless Seam component from a servlet:

...
import org.jboss.seam.Component;
...
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
     ContentLocal contentAction = (ContentLocal) Component.getInstance("contentAction");
          
     String result = contentAction.getResult(request.getParameter("id"));
     ...
}

ContentLocal is defined as such:

@Local
public interface ContentLocal {
     public String getResult(String id);
}

@Stateless
@Name("contentAction")
public class ContentAction implements ContentLocal {
     @Logger
     private Log log;

     @PersistenceContext
     EntityManager em;
     
     public String getResult(String id) {
          return em.find(MyObject.class, id).toString(); // null checks removed for simplicity; MyObject is a persistent object
     }
}

Under Seam 2.1.0.CR1 (migration done by copying jboss-seam*.jar to my project lib dir), the Component.getInstance(String) method call raises the following exception:

java.lang.IllegalStateException: No active application scope
        at org.jboss.seam.core.Init.instance(Init.java:110)
        at org.jboss.seam.contexts.BusinessProcessContext.getTaskInstance(BusinessProcessContext.java:224)

        at org.jboss.seam.Component.getInstance(Component.java:1872)
        at my.package.MyServlet.doGet(MyServlet.java:xxx)

Has some configuration or code style changed from #306 to CR1, or is there a bug in CR1?

Thanks for your help.

Do you have the context filter applied to your servlet?

[jkronegg]

The only filter defined is the Seam Filter. But I have a servlet definition. There is a snippet of my web.xml:

<filter>
  <filter-name>Seam Filter</filter-name>
  <filter-class>org.jboss.seam.servlet.SeamFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>Seam Filter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
...
<servlet>
  <servlet-name>Content Servlet</servlet-name>
  <servlet-class>my.package.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>Content Servlet</servlet-name>
  <url-pattern>/content/*</url-pattern>
</servlet-mapping>

I'm accessing the content using a GET on

http://localhost:8080/webAppName/content/getResult?id\=123

Try applying the ContextFilter to your servlet, or wrap your work in a ContextualHttpServletRequest

[jkronegg]

I wrapped my work in a ContextualHttpServletRequest:

public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException{
  final HttpServletRequest frequest
  new ContextualHttpServletRequest(frequest) {
    @Override
    public void process() throws Exception {
      ContentLocal contentAction = (ContentLocal) Component.getInstance("contentAction");
      String result = contentAction.getResult(frequest.getParameter("id"));
      ...
    }
  }.run();
}

and got another exception (notice that application scope changed for event context) :

java.lang.IllegalStateException: No active event context

From what I understand, Seam is not able to get the Context and/or Conversation when we use a simple servlet without ContextFilter (the ContextFilter will attach the current context to the servlet or the like). Is it correct?

What has changed from snapshot #306 to CR1 so that my previous code does not work anymore (after all, there is only one month between the two version)?

[danielc.roth]

Read this
29.1.4.8. Context management for custom servlets

Do you have the conversationId in the get request?

[jkronegg]

My components.xml contains:

<core:manager concurrent-request-timeout="500" conversation-timeout="120000" conversation-id-parameter="cid"/>
...
<web:context-filter url-pattern="/content/*"/>

Thus, my conversation id is cid and I have a ContextFilter configured.

I modified the servlet code just display which conversation id is configured:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  System.out.println("ContentServlet.doGet(): starting... *************************************************** ");
  System.out.println("guessed conversation id: cid="+request.getParameter("cid")+", conversationId="+request.getParameter("conversationId"));
  try {
    System.out.println("servlet received Manager conversation id parameter: "+Manager.instance().getConversationIdParameter()+"="+request.getParameter(Manager.instance().getConversationIdParameter()));
  } catch (RuntimeException e) {
    e.printStackTrace();
  }
  System.out.println("ContentServlet.doGet(): end. ********************************************************** ");
}//end doGet

By calling the servlet with (or without) the conversation id, I got:

These are the differences I can see in #330:

• Servlet re-initialisation


• destroying org.jboss.seam.core.events

What has change from #306 to CR1 or #330?

Help,

I am getting this same issue, I just upgraded from 2.0.2.SP1 to 2.1.0.CR1,  (Everything is configured and working for servlets in 2.0.2).

Thanks,
Sean.

Please file an issue in JIRA for this.

The JIRA issue is here: JBSEAM-3577

The JBSEAM-3577 issue is corrected in nightly build.

By the way, you also will get the java.lang.IllegalStateException: No active event context exception if your servlet is context-filtered in components.xml AND you use the ContextualHttpServletRequest in that servlet.
Of course, you should not have this setup configured, but who knows...
