The keywords to your problem are "Weblogic" and "restart". Here's documentation for the RedeployableActionServlet:
>> WebLogic (at least v6 and v7) attempts to serialize the >> TilesRequestProcessor when re-deploying the Webapp in development mode. The TilesRequestProcessor is not serializable, and loses the Tiles definitions. This results in NullPointerException and/or NotSerializableException when using the app after automatic redeploy.... The attached class extends the Struts Action servlet and fixes the problem by reloading the Tiles definitions when they have disappeared. http://struts.apache.org/struts-doc-1.2.4/api/org/apache/struts/actions/RedeployableActionServlet.html This class appeared in Struts 1.2.1. You can: (1) upgrade to Struts 1.2.4 (first 1.2 GA) (2) extract the binary and try to use it in 1.1. Paul --- "King, Matt" <[EMAIL PROTECTED]> wrote: > I was wondering if you could help me out.
