Upgrading WebSphere Application Server To Java 7

Due to migrating from JSF Beans to CDI Beans I needed to upgrade IBM WebSphere Application Server 8.5.5.9 to run the Java 7 SDK. First you have to download IBM Rational Application Developer for WebSphere Software V9.0 Multiplatform Multilingual - IBM WebSphere SDK Java (TM) Technology Edition V7.0 for WebSphere Application Server V8.5.5 Evaluation. Next extract the files and for your installation convenience move the disk folders to WAS855JDK7.

Next open IBM Installation Manager, go to File->Preferences, and add a respository which should point to the diskTag.inf in your disk1 folder. Back in the Installation Manager main menu, click Install, check IBM WebSphere SDK Java Technology Edition (Optional), click Next. In the next screen be sure to select the package group WAS is installed in, then click Next, and Install.

Next open Rational Software Architect Designer, go to Window->Preferences, go to Server->Runtime Environments, select your WAS, click Edit, change your runtime to JRE 1.7, 64 bit. and click Finish.

Also if you have a pre-existing profile on your server, use these instructions http://www-01.ibm.com/support/docview.wss?uid=swg21671938 to migrate it from 6 to 7.
