Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Class loading errors may occur * * when an application includes and uses * * Apache HTTP Components * **************************************************************** * RECOMMENDATION: * **************************************************************** The Open Source Software framework, Apache HTTP Components, included with WebSphere Application Server (WSAS) is not intended for direct application use. Class loading errors and unexpected behaviors may occur whenever a Java Platform, Enterprise Edition (Java EE) application also includes and uses Apache HTTP Components. As an additional means to resolve this problem the Application Server now accepts the system property "- Dcom.ibm.ws.classloader.server.alwaysProtectedPackages=org.apa che.http.", a control introduced by the feature "always-protected packages". This property setting enables the server to isolate the packages of Apache HTTP Components included with WSAS from all artifacts deployed on the application server. Usage intructions specific to isolating deployed artifacts from Apache HTTP Components are provided by IBM Technote "Isolating deployed artifacts from Apache HTTP Components provided by WebSphere Application Server", which is published at http://www.ibm.com/support/docview.wss?uid=swg21902432. General instructions for using always-protected packages are published in the WSAS Knowledge Center in section "Configuring always-protected (isolated) packages" of topic http://www- 01.ibm.com/support/knowledgecenter/?lang=en#!/SSAW57_ 8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/welc6tech_openso urce_isolate.html.
Problem conclusion
APAR PI43251 enables the user to hide the packages of Apache HTTP Components and other Open Source Software packages from all Java EE artifacts deployed on an Application Server. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.7. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
