Java

[joe74]

I've just installed java (my system up-to-date with kernel 3.3), but when I try to run a simple app, or do a simple "java" command, it returns:

Code: Select all

joe74@chilitower ~ $ java
* Home for VM 'sun-jdk-1.6' does not exist: /usr/lib/jvm/sun-jdk-1.6
* Invalid System VM: sun-jdk-1.6


Never used java before in SL, thus my question. I didn't find anything related in here.

I'm not a java user, not regular user, but needed to run this.

Thanks for the help.

Hi Joe74,

There was an issue with the default java-vm settings in some releases that may be resulting in this issue. We just need to reassign your java symlink to the correct version. Fortunately the eselect utility makes this very simple for us.

Code: Select all

$ su
# eselect java-vm list

You will receive a list of installed java virtual machines, You may also receive a couple errors at the top that there's no such file or directory. Chances are there's one that doesn't list an error at the top, on my system it's icedtea-7. Find the correlating number with that entry. Then:

Code: Select all

# eselect java-vm set <number>

If you also want to update your java plugin for your browser, you will need to do the same process with java-nsplugin (instead of java-vm).

What is wrong here?

Code: Select all

abayon-bb / # eselect java-vm list
Available Java Virtual Machines:
grep: /usr/share/java-config-2/vm/emul-linux-x86-java-1.6: No such file or directory
grep: /usr/share/java-config-2/vm/icedtea-6: No such file or directory
grep: /usr/share/java-config-2/vm/icedtea6-bin: No such file or directory
  [1]   emul-linux-x86-java-1.6
  [2]   icedtea-6
  [3]   icedtea6-bin
  [4]   icedtea-bin-7
  [5]   sun-jdk-1.6  system-vm

sabayon-bb / # eselect java-vm set 4
!!! Error: Usage [user|system] [vm]
exiting

Oops, looks like I missed a setting for user specific or system wide. Try:

Code: Select all

# eselect java-vm set system 4

Or possibly:

Code: Select all

# eselect java-vm set system icedtea-bin-7

Unfortunately, I'm not at my PC right now to verify which

Oops from me too
I always tried to replace "user|system" with something like "eselect java-vm set root system 4", but of course it is as simple as you wrote.

Thanks, camelinahat. It worked

Later for it to run the browser plugin:

Code: Select all

eselect java-nsplugin set 64bit icedtea-7

In case you have 64bits.
