![]() APAR status Closed as program error. Error description Customer has servlets which want to access to CICS EJB. To do that, the servlet needs to have access to CICS ORB instead of J2EE ORB. At WAS V3.5, the customer could control which ORB to be used by a servlet and things went fine. But after migrating to V4.01(or V4.0) WebSphere/390 PlugIn automatically looks up J2EE Server thus there is no way to control which ORB to be used by customer application. This disrupts them to run. To solve this problem, we would like to have an ability to disable the WAS/390 V4.01(V4.0)'s "automatic J2EE Server Lookup".Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of the WebSphere Application * * Server Version V4.0.1 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: There is no capability to disable * * automatic J2EE Server Lookup for the * * WebSphere Application Server Version * * V4.0.1 for z/OS and OS/390. * **************************************************************** * RECOMMENDATION: * **************************************************************** Version V3.5 users of the product could control which ORB was accessed by a servlet. For example, customers had servlets which accessed the CICS EJB, using the CICS ORB. With Version V4.0 and V4.0.1 this capability was removed. The WebSphere Application Server plug-in automatically looks up the J2EE Server, and there is no way to control which ORB is used by a servlet. The ability for users to disable automatic J2EE Server Lookup is required.Problem conclusion The capability to specify a new parameter for the existing property appserver.java.extraparm in the was.conf file was added. Users may now specify appserver.java.extraparm=-DDisable.J2EE=true/false. If the value TRUE is specified for the parameter, the lookup for the J2EE ORB is disabled. This gives the customer the ability to disable J2EE Server Lookup. The default for this parameter is FALSE. When the value FALSE is specified or the default is taken, the J2EE Server lookup is performed. Documentation Changes: The following information will be added to Appendix C "Using the Alternate Configuration Option" of "WebSphere Application Server V4.0.1 for z/OS and OS/390: Assembling Java 2 Platform, Enterprise Edition (J2EE ) Applications" under "Rules" 2. If you are not hosting any of your Web applications in a Web container and want to use a non-WebSphere for z/OS ORB in conjunction with the V3.5 runtime, such as the CICS ORB, set the value of the appserver.java.extraparm=-DDisable.J2EE property in the V4.0.1 was.conf file to TRUE. However, be aware that changing the setting of this property removes your connection to the J2EE server environment from the V3.5 runtime. When you are ready to start hosting Web applications in a Web container, you MUST change the value on this property back to FALSE before attempting to access Web applications hosted in the Web container from the V3.5 runtime. Note: When the appserver.java.extraparm=-DDisable.J2EE parameter is set to TRUE, you may still deploy Web applications into the V3.5 plug-in runtime. In addition, you may bring up a J2EE server and use the HTTP Transport to dispatch HTTP requests directly to the J2EE server.
