CMVC Defect: 546929 Byte size of APAR: 18419 Date: 2008-09-22 Abstract: When a service integration bus has security enabled applications using JMS may receive a CWSIC8002E runtime exception Description/symptom of problem: PK71766 resolves the following problem: ERROR DESCRIPTION:? When a service integration bus has security enabled, applications using JMS may receive an exception with the following message: com.ibm.websphere.sib.exception.SIErrorException: com.ibm.websphere.sib.exception.SIErrorException: CWSIC8002E: An internal error occurred. An unknown or unexpected exception was thrown by the core API: exception CWSIC8007E: An exception was caught from the remote server with Probe Id 3-004-0013. Exception: java.lang.NullPointerException.. This error may prevent applications from connecting, sending or receiving messages. LOCAL FIX:? PROBLEM SUMMARY:? USERS AFFECTED: Users of the default messaging provider for WebSphere Application Server V7.0 with bus security enabled PROBLEM DESCRIPTION: When a service integration bus has security enabled applications using JMS may receive a CWSIC8002E runtime exception RECOMMENDATION: None The following runtime exception may be thrown a JMS application: com.ibm.websphere.sib.exception.SIErrorException: com.ibm.websphere.sib.exception.SIErrorException: CWSIC8002E: An internal error occurred. An unknown or unexpected exception was thrown by the core API: exception CWSIC8007E: An exception was caught from the remote server with Probe Id 3-004-0013. Exception: java.lang.NullPointerException. If observed this prevents applications from connecting, sending or receiving messages. This occurred because the service integration bus code failed to fill in an internal field correctly (the bus name). This was required to authorize a user, so the NullPointerException was thrown and the user was unable to connect to the bus. PROBLEM CONCLUSION:? This APAR resolves the problem, allowing authorized users to connect to the bus. The fix for this APAR is currently targeted for inclusion in fixpack 7.0.0.1. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980 Install Fix to all WebSphere installations unless special instructions are included below. Special Instructions: None NOTE: The user must: * Logged in with the same authority level when unpacking a fix, fix pack or refresh pack. * Be at V7.0.0.0 or newer of the Update Installer. Certain iFixes may require a newer version of the Update Installer and the Update Installer will inform you during the installation process if a newer version is required. This can be checked by reviewing the level of the Update Installer in file /updateinstaller/version.txt. The Update Installer can be downloaded from the following link: http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg24020212 1) The fix is delivered as a single file with a .pak extension (such as 7.0.0.1-WS-WAS-IFPK12345.pak). Copy the .pak file directly to the maintenance directory, /maintenance. 2) Shutdown WebSphere 3) For IBM i users, use the update command to install and uninstall the interim fix. The IBM Information Center can provide additional details, if needed, on the use of this command. http://www14.software.ibm.com/webapp/wsbroker/redirect?version=compass&product=was-nd-iseries&topic=rins_update. For non-IBM i users, launch the Update Installer and click the Next button on the Welcome page. 4) Enter the directory path of the installation location of the WebSphere product you want to update, and click the Next button. 5) Select the "Install maintenance package" operation and click the Next button. 6) Enter the directory path of your maintenance directory where you have the maintenance packages (.pak files) and click the Next button. 7) The Available Maintenance Package to Install page should list all maintenance packages (.pak files) that it finds in the directory path provided in the previous step. The Update Installer will select the correct maintenance packages based on your system configuration and will not allow an invalid combination to be installed. Please keep the Update Installer recommendations and click the Next button and continue with the installation of the maintenance package. To determine why some maintenance packages have been identified as not applicable, see description in log found in /logs/tmp*/updatelogs.txt 8) For all platforms except Windows. In pre-install summary panel, use the "verify permission" feature to verify the user has permissions to apply updates to files associated with the selected maintenance. Correct any file permissions before clicking next to start the install. 9) Restart WebSphere Directions to remove fix: 1) Shutdown WebSphere 2) Start Update Installer 3) Enter the installation location of the WebSphere product you want to remove the fix. 4) Select "Uninstall maintenance package" operation. 5) Select name of the maintenance package to uninstall (PKxxxxx.pak). 6) UnInstall maintenance package. 7) Restart WebSphere Directions to re-apply fix: 1) Shutdown WebSphere. 2) Follow the Fix instructions to apply the fix. 3) Restart WebSphere.
