Download Description
PQ82970 resolves the following problem:

ERROR DESCRIPTION:
A servlet or JSP that sets the content-language header twice causes a NullPointerException unless an expiration header is set.

PROBLEM SUMMARY:
If a servlet or JSP calls addHeader twice and NO expiration header, a NullPointerException is thrown. If the servlet or JSP calls addHeader twice and DOES set an expiration header, all works fine. If setHeader is used, no exception is thrown.

USERS AFFECTED:
WebSphere Application Server V4.0.7 servlet or JSP users.

PROBLEM DESCRIPTION:
A servlet or jsp that calls removeHeader will leave a hole (null) in the header list. This also causes a NullPointerException.

RECOMMENDATION:

Apply interim fix PQ82970.
