Which Java version is my WebSphere Application Server V8.5 using?

Body

In one of Vish's blogs, he explains how to install the optional Java 7.x on WebSphere Application Sever 8.5:

Once it is installed, however how can you tell which version of Java is actually being used?  You can look at the SystemOut.log header, but the output may be a little bit confusing.  Here are some examples to help clarify what the output means:

SystemOut.log:

1)  Using Java 6 with no Java 7 package installed (default)

************ Start Display Current Environment ************
WebSphere Platform 8.5.5.0 [ND 8.5.5.0 gm1319.01] running with process name
Host Operating System is Windows 7, version 6.1
Java version = 1.6.0, Java Compiler = j9jit26, Java VM name = IBM J9 VM
was.install.root = C:\Program Files\IBM\WASND85
user.install.root = C:\Program Files\IBM\WASND85\profiles\AppSrv01
Java Home = C:\Program Files\IBM\WASND85\java\jre
ws.ext.dirs = C:\Program Files\IBM\WASND85/java/lib;C:\Program Files\IBM\WAS
Classpath = C:\Program Files\IBM\WASND85\profiles\AppSrv01/properties;C:\Pro
Java Library path = C:\Program Files\IBM\WASND85/lib/native/win/x86_64/;C:\P
Orb Version = IBM Java ORB build orb626-20130112.01
************* End Display Current Environment *************
 

<Next Step: Install Java7 package via Installation Manager>

2) Using Java 6 with the optional Java 7 package installed but not yet enabled

************ Start Display Current Environment ************
WebSphere [IBMJAVA7 7.0.4.1 gm1318.03]Platform 8.5.5.0 [ND 8.5.5.0 gm1319.01] running with process name
Host Operating System is Windows 7, version 6.1
Java version = 1.6.0, Java Compiler = j9jit26, Java VM name = IBM J9 VM
was.install.root = C:\Program Files\IBM\WASND85
user.install.root = C:\Program Files\IBM\WASND85\profiles\AppSrv01
Java Home = C:\Program Files\IBM\WASND85\java\jre
ws.ext.dirs = C:\Program Files\IBM\WASND85/java/lib;C:\Program Files\IBM\WASND85\profiles\AppSrv01/class
Classpath = C:\Program Files\IBM\WASND85\profiles\AppSrv01/properties;C:\Program Files\IBM\WASND85/prope
Java Library path = C:\Program Files\IBM\WASND85/lib/native/win/x86_64/;C:\Program Files\IBM\WASND85\jav
Orb Version = IBM Java ORB build orb626-20130112.01
************* End Display Current Environment *************

<Next Step:  Use "managesdk.bat" to change to Java7>

Steps to switch over to the use of Java 7:

C:\Program Files\IBM\WASND85\profiles\AppSrv01\bin>managesdk.bat -listAvailable
CWSDK1003I: Available SDKs :
CWSDK1005I: SDK name: 1.6_64
CWSDK1005I: SDK name: 1.7_64
CWSDK1001I: Successfully performed the requested managesdk task.

C:\Program Files\IBM\WASND85\profiles\AppSrv01\bin>managesdk.bat -enableProfileAll -sdkname 1.7_64 -enableServers
CWSDK1017I: Profile AppSrv01 now enabled to use SDK 1.7_64.
CWSDK1001I: Successfully performed the requested managesdk task.

3) Using Java 7
