PH26842 resolves the following problem:

ERROR DESCRIPTION:
When running WebSphere Application Server fixpack 9.0.5.4, if a URL is invoked that is protected by the SAML Web SSO TAI, during the processing of the request a classloader error occurs.

com.ibm.ws.security.web.TrustAssociationUtil
at com.ibm.ws.security.web.saml.util.SAMLTaiState.saveReqURL(SAMLTaiState.java:289)

...

USERS AFFECTED:
All users of IBM WebSphere Application Server 9.0.5.4 and SAML Web SSO

RECOMMENDATION:
Install a fix pack or interim fix that includes this APAR.

PROBLEM CONCLUSION:
The com.ibm.ws.security.web package is added to the imports list in the MANIFEST.MF file in the com.ibm.wsfp.main.jar file, preventing the ClassNotFoundException error for the com.ibm.ws.security.web.TrustAssociationUtil class.

The fix for this APAR is targeted for inclusion in fix pack 9.0.5.5.  For more information, see 'Recommended Updates for WebSphere Application Server':
