![]() APAR status Closed as program error. Error description During the WebSphere 5.0 Beta we opened PMR 9398 to track the change in filter invocation by WebSphere. WebSphere had been invoking servlet filters on all jsps when the url-pattern in web.xml is *.jsp and changed to only invoke the filter for the top level jsp, not included jsps. Although the filter invocation change is permanent we discovered that WebSphere was wrapping the request/response of included jsps. The original request/response objects are then no longer visible to the application. We were told this was a known problem and an e-fix would be available after GM. The target was the first week of December. I believe the internal WebSphere defect was 15464.Local fix N/AProblem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server developers * * using servlet 2.3 filtering of * * requests and response feature. * **************************************************************** * PROBLEM DESCRIPTION: WebSphere is incorrectly wrappering * * the response and request objects * * for each dispatch to a resource. * **************************************************************** * RECOMMENDATION: * **************************************************************** According to the Servlet 2.2 Specification, Servlet Filtering should be done only on the original request and response objects. WebSphere is filtering external and internal servlet dispatches resulting in multiple filters per request and response.Problem conclusion Removed additional wrappering done inside of the webcontainer and streamlined the Filtering process.Temporary fix ZE FIX ERROR PQ72070 02/03/25Comments
