Question

I have the following questions on WAS 8.5 installation:

1. Can Java 7 be installed outside {or}c:\IBM\Websphere\Appserver
2. Can the Java 7 name be other than Java1.7_64?

Also how to get the info. using any bat/sh file from IBM

Thanks in advance

Answer 1

No to both: there is no way to change the Java install directory.

To determine the configured JDK, source setupCmdLine and use the JAVA_HOME variable. For example, on UNIX:

. /path/to/profile/setupCmdLine.sh
echo $JAVA_HOME

…and on Windows:

C:\path\to\profile\bin\setupCmdLine.bat
echo %JAVA_HOME%

If you need to automate discovery, you might write a temporary batch file with the following contents, execute it (e.g., using ProcessBuilder), and then parse the resulting output:

@echo off
call "C:\path\to\profile\bin\setupCmdLine.bat"
echo JAVA_HOME=%JAVA_HOME%
