PK67022; 6.1.0.17: Duplicate mapping error message includes a call stack

Download Description

PK67022 resolves the following problem:

ERROR DESCRIPTION:
When there is a mapping of /servlet/* in an application, it clashes with the reserved mapping for when serveServletsByClassname is enabled. As a result an error message is printed which includes a complete exception stack. The message should not include the exception stack.

LOCAL FIX:
The exception stack may be ignored.

PROBLEM SUMMARY

USERS AFFECTED:
IBM® WebSphere® Application Server Version 6.1 users of serveServletsByClassname.

PROBLEM DESCRIPTION:
Starting from V6.1.0.15, an exception appears in the SystemOut.log file during application start if
serveServletsByClassname is enabled and a problem is found with the application servlet mappings. For example, this will occur if the application specifies a mapping of "/servlet/*".

RECOMMENDATION:
None

As a result of PK57136, an exception stack was added to a message which is output during application start if serveServletsByClassname is enabled and a problem is found with the application servlet mappings. For example:

[4/21/08 6:59:09:250 EDT] 00000014 WebApp E Error while adding servlet mapping. java.lang.Exception: Mapping clash for

PROBLEM CONCLUSION:
The WebContainer has been modified to suppress the exception stack included with the error while adding servlet mapping" message. Note that in the event of this error, an ffdc record which includes the stack information will continue to be created.

The fix for this APAR is currently targeted for inclusion in Fix Pack 6.1.0.19.
