Download the J2SE SDK (not the JRE) and install it on your system, if you have not already done so.
The J2SE SDK can be downloaded from http://java.sun.com/j2se.
Completely stop the Application Server.
You can use the following command line:
as-install/bin/asadmin stop-domain |
Alternatively, you can use the Administration Console GUI:
Edit the install_dir/config/asenv.conf file (asenv.bat on Windows), changing the value for AS_JAVA to point to the new J2SE home directory.
Edit the as-install/samples/common.properties file, changing the line beginning com.sun.aas.javaRoot... to reference the new J2SE home directory.
Restart the Application Server.
as-install/bin/asadmin start-domain |
If you are upgrading from a JDK version earlier than the bundled version (JDK 1.4.2_06), then you cannot upgrade to J2SE 5.0 or later using just the steps above. Specifically, in addition to the above steps, you must delete any existing domains and recreate them.
