Problems runing Java j2sdk under Knoppix 3.3

[nik03]

Hi All

I've using Knoppix 3.3 on Harddisk and I've installed java j2sdk1.4.2_05.
While invoking the compiler javac the folowing error message comes up:

Error Occured during Initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

invoke: javac test.java

I've already set the Path Variable:
/usr/java/j2sdk1.4.2_05/bin

The man pages are running correctly.

Would be nice if someone has a hint.


Thanx Norbert

Knoppix used to come with BlackDown 1.4.1. Make sure the JDK you installed appears first on your PATH, so it's that version of java that's invoked. Simply type "java -version"'

[nik03]

I've already set it at the beginning of the PATH Variable. Is there a dependencie of the Shell I use?

[baldyeti]

When are you seeing the error message: when compliling or when trying to execute your compiled test program?

Also have you defined the JAVA_HOME environment variable?

[nik03]

See this message usig the compiler and the same message when try to get the version (java -version)

My Configuration in the /etc/profile file:

JAVA_BINDIR=/usr/java/j2sdk1.4.2_05/bin
JAVA_HOME=/usr/java/j2sdk1.4.2_05
JDK_HOME=/usr/java/j2sdk1.4.2_05
PATH="/usr/java/j2sdk1.4.2_05/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin:/usr/games"
export JAVA_BINDIR
export JAVA_HOME
export JDK_HOME
export PATH

It all looks fine to me; what does "type java" report? And you did re-logon after editing /etc/profile, didn't you? Also, root might be overrinding the PATH setting for security reason. so try with another account.

[nik03]

type java gets the following:

java is /usr/java/j2sdk1.4.2_05/bin/java

I've tried with a normal User account, the same result

[baldyeti]

Javac might previously have been aliased to gcc (unless the Sun javac is 1st on your PATH, which seems to be the case...). Please confirm with "type javac"
Do you have CLASSPATH defined by any chance, which might interfere. Other than that, I am running out of ideas; sorry.

Hi Norbert:

I haven't been able to run the installed sdk in my knoppix 3.3, but I intalled the sun jre successfully.

You have to edit your /etc/profile and I think the most important change a sinbolic link in /usr/bin

   #cd /usr
   #ln -f -s usr/j2re1.4/bin/java java
   #java -version

After doing this I can run eclipse and other java aplications.

I tried now a different installmod (-localinstall) for the source *.bin file from sun.com

invoke:
./j2sdk-1_4_2_05-linux-i586.bin -localinstall

After installing this way I updated the profile and now it works.

At first I unziped the *. rpm file, converted to a *.deb file to installed it by alien

Thanx
Norbert
