-------------------------------
I have meet the same issue.
I must use struts2 + tiles in jdk1.4.2.(struts2.0.14 + tiles2.0.6)
But tiles can't work.
struts2-tiles-plugin and tiles jars were transfered for jdk1.4 by using
RetroTranslator.
Below is my exception:
[11/28/08 14:45:40:546 CST] 4c844c84 WebGroup E SRVE0026E: [Servlet
Error]-[]: java.lang.NullPointerException

efaultWorkflowInterceptor.java:221)
Below is org.apache.struts2.views.tiles.TilesResult.doExecute java code:
public void doExecute(String location, ActionInvocation invocation) throws
Exception {
setLocation(location);
ServletContext servletContext =
ServletActionContext.getServletContext();
TilesContainer container = TilesAccess.getContainer(servletContext);
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
container.render(location, request, response);
}
I debugged and fund that "container" is null, a exception will be thrown when
launch this code:
container.render(location, request, response);
I found that "org.apache.struts2.tiles.StrutsTilesListener" is not run when web
application start!
My application can run smoothly in jdk1.5, but tiles can't work in jdk1.4.2
I promise it's a bug.

> Key: WW-2897
> URL: https://issues.apache.org/struts/browse/WW-2897
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Tiles
> Affects Versions: 2.0.11.2
> Environment: websphere6.0 (jdk1.42),all the referenced jar is in the
> struts-2.0.11.2-all.zip downloaded from the official site.
> Reporter: careprad
> Priority: Blocker
>
> first of all,the reason is the exception on ServletDispatcherResult.doExecute:
> setLocation(location);
> javax.servlet.ServletContext servletContext =
> ServletActionContext.getServletContext();
> TilesContainer container =
> TilesAccess.getContainer(servletContext); //here get null
> container
> javax.servlet.http.HttpServletRequest request =
> ServletActionContext.getRequest();
> javax.servlet.http.HttpServletResponse response =
> ServletActionContext.getResponse();
> container.render(location, new Object[] {request, response});
> //here will throw the null pointer exception
> I traced the exception in the StrutsTilesListener ,it do not work at all,I
> suppose it is the static initialize method work in error:
> INIT.put(
> "org.apache.tiles.factory.TilesContainerFactory",
>
> (class$org$apache$struts2$tiles$StrutsTilesContainerFactory == null
> &&
> (class$org$apache$struts2$tiles$StrutsTilesContainerFactory =
> (new
> StrutsTilesContainerFactory[0]).getClass().getComponentType())
> == null
> ?
> class$org$apache$struts2$tiles$StrutsTilesContainerFactory
> :
> class$org$apache$struts2$tiles$StrutsTilesContainerFactory)
> .getName());
> this code is what I can't understand!and How can I get the source code of the
> pluggin?
