Bridge Interceptor

[sven.schulz]

I wonder how to activate the bridge interceptor in org.jboss.portal.bridge. I think I have to add a line to jboss-container.xml. Is this true? Is there any meaning associated with the order of the interceptor elements therein?

[julien1]

you can download the example uing struts and look at the configuration.

the struts mail demo is what interest you on this page : http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossPortalSamples

Hi Julien,

I am trying to integrate my own bridge for Oracle ADF Faces. Even with your hint I am not able to figure out how to get the bridge interceptor working. When I invoke

<JBossServletContextProvider>.getServletContext(null)

an IllegalStateException is thrown, indicating that no bridge is set. I think this results from the fact, that the interceptor is not in position. If I modify the jboss-container-xml of the portal to include an entry for the interceptor a NullPointerException is thrown, that originates from the BridgeInterceptor accessing an object that is not available.

Any idea?

[julien1]

it is because you need to change the invocation stack on your portlet and activate the one specific to bridged configuration :

in jboss-portal.xml add the line <config-name>Struts</config-name> like :

<portlet-app>
 <portlet>
 <portlet-name>StrutsPortletDemo</portlet-name>
 <!-- Use the specific struts container configuration -->
 <config-name>StrutsPortlet</config-name>
 </portlet>
</portlet-app>

then the ServletContextProvider should work and give you what you expect.

I am trying to use the bridge to create a portlet around an existing application (JPivot). I have got the portlet WAR set up, and it deploys without errors.

The init method on my portlet is called. It sets up a ServletContextProvider like the StrutsPortlet does.

I have no security set up.

On login, the portlet appears on the Page menu with a URL of http://localhost:8080/portal/auth/index.html?ctrl:id=page.default.JPivotDemo.

When I select it, I get a screen back that just has the nodesk look and feel without any content. In the log, I have:

The doView method of my portlet is not being called.

 <instance-ref>JPivotDemo.JPivotPortlet.JPivotPortletDemoInstance</instance-ref>
 <region>center</region>
 <height>0</height>
 </window>
 </page>
</pages>

Any pointers?

Thanks in advance,

Ahhh, I see the following when the portlet deploys:

ERROR [org.jboss.portal.core.deployment.jboss.PortletAppDeployment] No config for the name JPivotPortlet will use the default configuration

After some digging around in the code, this is caused by a reference to the config-name element in jboss-portlet.xml.

In org.jboss.portal.portlet.deployment.jboss.PortletAppDeployment.buildComponentConfiguration(String portletName), the value of the config-element is being looked for in the configurations variable.

Th configurations variable is set up in create(). The data is loaded from /standardjboss-portlet.xml in the portal-core.sar.

The StrutsPortlet configuration in standardjboss-portlet.xml does not have anything specific to Struts in it. The only difference from the default one is the inclusion of the BridgeInterceptor, which sets up the ServletContextProvider. Maybe this configuration should be called BridgedPortlet?

So I put the line

<config-name>StrutsPortlet</config-name>

into jboss-portlet.xml. Now there is no error like above in the log when I deploy.

But I am still getting the same behavior when I access the portlet: a theme only screen and the doView method on my portlet class is not called. I put some logging in to see what invocations were happening

The behavior above where my portlet was not being called indicated that no page was found in *-pages.xml. Should this throw an exception?

After much comparison of my config files to helloworld, and looking at the Reference Guide, I realized that my instance-ref in *-pages.xml was wrong. It needs to be:

[<app-name> from jboss-app.xml].[<portlet-name> from portlet.xml].[<instance-name> from portlet-instances.xml]

Note that the Reference Guide is wrong about the <app-name> in section 2.6. It is in jboss-app.xml, not jboss-portlet.xml.

THANKS! I wasn't aware of the jboss-app.xml, was just wondering why my own portlet suddenly did not show up any more with the portal sources from cvs head.

[kanthrao]

When I try to get the servletcontext (servletContextProvider.getServletContext(this)) I get a IllegalStateException

java.lang.IllegalStateException: No bridge set
at org.jboss.portal.bridge.JBossServletContextProvider.getServletContext(JBossServletContextProvider.java:53)

I have this in my portlet.xml and jboss-portlet.xml

<init-param>
 <name>ServletContextProvider</name>
 <value>org.jboss.portal.bridge.JBossServletContextProvider</value>
</init-param>

<portlet>
 <portlet-name>StrutsPortletDemo</portlet-name>
 <config-name>StrutsPortlet</config-name>
 </portlet>

The init method in my portlet sets up a ServletContextProvider like the StrutsPortlet does. Also struts-demo is running fine.
Any help would be much appreciated.
