InfoCenter Home > 3.3.3.1: Updating JSP .91 files for use with Version 3.5If using JSP .91 files or servlets that you have not already been using with Version 3.0x, and the JSP .91 files or servlets cast to either of these methods:
Additionally, if migrating JSP .91 files last used with IBM WebSphere Application Server Version 1.x, you need to eliminate <REPEATGROUP> tags. See below for details. Option 1: Modify deprecated callsThe tables summarize calls to the deprecated HttpServiceRequest and HttpServiceResponse classes, and provide replacement code.
A code example is provided to show how to migrate to RequestDispatcher:
Option 2: Recompile filesAs an alternative to replacing the deprecated calls to HttpServiceRequest and HttpServiceResponse, recompile your JSP .91 files or servlets developed for Application Server Version 2.0x before using them with Application Server Version 3.5. Recompiling is necessary because starting with Version 3.0x, HttpServiceRequest and HttpServiceResponse are provided as interfaces (instead of classes) that are implemented by the WebSphere servlet engine. If you do not recompile the servlets or JSP files, the Java Virtual Machine (JVM) will crash on Windows NT systems due to a suspected bug in the JDK. It is possible that you already recompiled the files for use with Version 3.0x. In such a case, it is not necessary to compile them again for Version 3.5. Migrating JSP .91 files from IBM WebSphere Application Server Version 1.xThe Application Server Version 1.x supported an additional tag, <REPEATGROUP> for repeating a block of HTML tagging for data that is already logically grouped in the database. Because this release does not support the <REPEATGROUP> tag, remove that tag from any JSP files that you want to use on the Application Server Version 3.5.
