<P>
<p> 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. </p> <p> This bug report proposes a workaround for this problem, in the hope it will help others and maybe motivate an actual fix. </p> <p> The attached class extends the Struts Action servlet and fixes the problem by reloading the Tiles definitions when they have disappeared. </p> <p> For background discussion see http://issues.apache.org/bugzilla/show_bug.cgi?id=26322 </p>
