resource bundles and null pointer exception
New Member Posts: 8 Join Date: 6/20/07 Recent Posts
I have a Liferay 4.2.2 professional installation running on tomcat 5.5.23. I have written my own portlet and deployed it successfully by adding it under WEB-INF/classes/com/myorg/ and editing WEB-INF/portlet-ext.xml, WEB-INF/liferay-portlet-ext.xml and WEB-INF/liferay-display.xml.

My problem happens when I try to modfiy the code from using the StrutsResourceBundle to using my own. I did the following:

1) created a MyResources.properties file and placed it under WEB-INF/classes/com/myorg.
2) Edited the portal-ext definition file so that the resource-bundle element is:
<resource-bundle>com.myorg.MyResources</resource-bundle>

After these changes running liferay causes a NullPointerexception with the following stack-trace:

As I said, defining the resource bundle to be com.liferay.portlet.StrutsResourceBundle works just fine, my change doesn't.

I would appreciate any pointers as to what I am doing wrong.

I never found or got an answer to this issue, so I ended up just adding my stuff to the StrutsResoruceBundle.

This involved:
  • In the portlet-ext.xml configuration for the portlet, declare it to use the com.liferay.portlet. StrutsResourceBundle
  • Added a Language-ext.properties file to WEB-INF/classes/content with the property javax.portlet.title.XXX (where XXX is my portlet name) set to the desired value, for example, "javax.portlet.title.E01=My Title"


Didn't solve the original problem, but was the only way I could get the title I wanted to show up.
