Description

Hello,
I have to use struts2 + tiles in jdk1.4.2.
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);

why container is null?
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
