Error during running JEMS Installer

[gorathek]

Hi!

When i try to use a jems installer version 1.2.0.GA on RH 4 update 4 ES with JDK 1.4.2._19 installed i got a error as show below:

[root@localhost tmp]# java -jar jems-installer-1.2.0.GA.jar
Warning: -jar not understood. Ignoring.
Exception in thread "main" java.lang.NoClassDefFoundError: jems-installer-1.2.0.GA.jar

at __libc_start_main (/lib/tls/libc-2.3.4.so)
at _Jv_RegisterClasses (/tmp/java.version=1.4.2)

Can someone tell me what does it means and how to solve it?

Regards

Please post the output of

java -version

Also, i would not recommend using the JEMS installer since there have been many issues reported in it. The easiest way to install JBossAS is to download the zip file and unzip it to a locaiton of your choice.

Hi !

Below is a output from java -version from my host:

[root@localhost ~]# java -version
java version "1.4.2"

You are using the gcj Java vendor. Please download Sun Java and set JAVA_HOME to point to the Sun Java JDK. That should fix the issue.

The strange thing is that i dowloaded it form SUN page :)
And you maybe know some way how to remove that installed thing?
And a correct link to JDK?

[jaikiran]

In that case, i guess your JAVA_HOME points to the incorrect JDK installation or even the PATH might be pointing to the incorrect JDK. Post the output of

echo $JAVA_HOME

and

echo $PATH

To set it correctly, here's what you can do (assuming your Sun JDK is installed at /opt/Java/jdk1.5.0_17/):

export JAVA_HOME=/opt/Java/jdk1.5.0_17/
export PATH=$JAVA_HOME/bin:$PATH

[gorathek]

[root@localhost j2sdk1.4.2_19]# echo $JAVA_HOME
/usr/java/j2sdk1.4.2_19/
[root@localhost j2sdk1.4.2_19]# echo $PATH
/usr/java/j2sdk1.4.2_19//bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:/usr/java/j2sdk1.4.2_19/bin
[root@localhost j2sdk1.4.2_19]#

[jaikiran]

[root@localhost j2sdk1.4.2_19]# echo $PATH
/usr/java/j2sdk1.4.2_19//bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:/usr/java/j2sdk1.4.2_19/bin

You have problem in the path. Note the double // in /usr/java/j2sdk1.4.2_19//bin? It should just be /usr/java/j2sdk1.4.2_19/bin.

And reading my earlier post again, i realize that i was the one who posted the incorrect commands :-)

So here's the corrected version:

export JAVA_HOME=/opt/Java/jdk1.5.0_17
export PATH=$JAVA_HOME/bin:$PATH

Thanks it helps :)
