MY FINDINGS :
i found https://issues.jboss.org/browse/SOLDER-311 where they asked to add following filter:
{code}<filter>
<filter-name>Seam 3.1 Servlet Filter</filter-name>
<filter-class>org.jboss.solder.servlet.event.ServletEventBridgeFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Seam 3.1 Servlet Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>{code}
but after adding this I'm gettig NullPointerException , which is mentioned in the thread itself and you can find it there.
I'm not able to find any solution for this.
Even I'm Not clear about the root cause of the Exception.
I'm able to call other methods of some other class but not from this class.
any help will be great !!!
plz help ...
Thanks
