Upgrading to Struts 2.3.32. Getting null pointer exception with getBaseTilesDefinitionURLs

I am upgrading an existing App to Struts 2.3.32 and when I add the App to a WebSphere 7.0 server I get the following error.

The jar files I have added (or updated) to the app are:

New or replacement Jars

All of the jar files in the lib of the WEB-INF folder are:

Solution

  • Per my understanding of Aleksandr M's comment I removed the following lines from my web.xml file.

    <context-param>
    <param-name> org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
    <param-value>/WEB-INF/tiles/tiles.xml,/WEB-INF/tiles/gis-tiles.xml </param-value> 
</context-param>

    I no longer get the null pointer exception. I have other issues which I am working through but this appears to have fixed the issue I originally asked about.

    EDIT: Based on the link provided by Aleksandr in the comment on this answer, I figured out the issue was the file WEB-INF/tiles/gis-tiles.xml did not exist so I removed it from the <param-value> element.
