[jira] Created: (JS2-254) NullPointerException in PortletSession.getPortletContext()
NullPointerException in PortletSession.getPortletContext()
----------------------------------------------------------
Key: JS2-254
URL: http://issues.apache.org/jira/browse/JS2-254
Project: Jetspeed 2
Type: Bug
Components: Container
Versions: 2.0-dev/cvs
Environment: WindowsXP SP2, JBoss 4.0.1SP1, HSQL
Reporter: David Pankros
>From a JSR168 portlet's render method, calling:
request.getPortletSession().getPortletContext();
generates the following exception:
java.lang.NullPointerException
at org.apache.pluto.core.impl.PortletSessionImpl.getInternalPortletContext(PortletSessionImpl.java:242)
at org.apache.pluto.core.impl.PortletSessionImpl.getPortletContext(PortletSessionImpl.java:199)
... portlet code ...
at javax.portlet.GenericPortlet.render(GenericPortlet.java:175)
at org.apache.jetspeed.factory.JetspeedPortletInstance.render(JetspeedPortletInstance.java:96)
at org.apache.jetspeed.container.JetspeedContainerServlet.doGet(JetspeedContainerServlet.java:224)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
This was confirmed by Ate Douma on the jetspeed-users list. His explanation is:
...[I] already have traced down the cause.
The bad news:
This isn't something new but a missing implementation of a Pluto object model interface, namely:
PortletEntity.getPortletApplicationEntity() (which returns null in Jetspeed).
After scanning the Pluto container sources, this is the *only* place this method is invoked at all (in the container that is) and we must have simply overlooked it.
What Pluto actually does (in PortletSessionImpl.getInternalPortletContext) is trying to get to the current PortletApplicationDefinition:
portletEntity.getPortletApplicationEntity().getPortletApplicationDefinition()
This could just as well have been written as:
portletEntity.getPortletDefinition().getPortletApplicationDefinition()
which *is* implemented in Jetspeed.
