AS5 for JDK5, JDK6 - How to tell the difference

[rnicholson10]

If I unzip either "jboss-5.0.1.GA.zip" or "jboss-5.0.1.GA-jdk6.zip", they both unzip to the same directory name: "jboss-5.0.1.GA".

So how do I tell which version, JDK5 vs JDK6, an installation is after the unzip.

It might be an idea to force the JDK6 version to unzip to "jboss-5.0.1.GA-jdk6" to avoid confusion.

Cheers,

Ross

Good point. You can find out with twiddle:

JBOSS_HOME\bin>twiddle get "jboss.system:type=Server" BuildDate BuildJVM BuildOS
BuildDate=March 7 2009
BuildJVM=1.5.0_16-b02(Sun Microsystems Inc.)
BuildOS=Windows XP(x86,5.1)

Two ways I can think of.

1) Visual inspection: the jdk6 variant has jbossws*.jar files in lib/endorsed.

2) Via the log file: the jdk6 variant reports the version as:

12:55:56,005 INFO [ServerImpl] Release ID: JBoss [Morpheus] 5.0.0.GA (build: SVNTag=JBoss_5_0_0_GA date=200812042120)

while the jdk5 variant reports the version as:

15:33:59,995 INFO [ServerImpl] Release ID: JBoss [Morpheus] 5.0.0.GA (build: SVNTag=JBoss_5_0_0_GA date=200812041714)

Note the slightly different build dates.

I like to have both variants handy, so after I unpack them I rename the base directory to add the jdk version, Examples: jboss-5.0.0.GA-jdk5 and jboss-5.0.0.GA-jdk6.

Running twiddle on a Java 6 build is reported like this:

BuildDate=February 23 2009
BuildJVM=11.0-b16(Sun Microsystems Inc.)
BuildOS=Linux(i386,2.6.9-67.0.1.ELsmp)

Java 11!!!! That must be the best version of Java ever!

Kidding, there would appear to be discrepancy between the java versions returned by running "java -version".

Java 5:

java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing)

Java 6:

java version "1.6.0_12"
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)

You'll note that the build number for the client VM differs between 5 and 6. On 5 in infers the java versions and on 6 it does not. This behaviour occurs on both windows and linux.

Maybe we need a "BuildRuntime" variable as well???
