I've switched from Windows to Linux as my primary client; I now have no Windows machines at home.

... and I have a minor problem.

OS - Kubuntu, 64 bit, 9.10 Karmic Koala.
Installed - svn, ant and java - using...
sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
... which also seems to have installed sun-java6-bin as well.

On trying to run the ant, however, it is complaining that it can't find the javac compiler. JAVA_HOME is pointing to "/usr/lib/jvm/java-6-openjdk/jre" and there are files in there, but obviously not what I need.

Can anyone help please?

Michelle.

you cant compile with jre, get jdk

[msknight]

OK, I installed the JDK with...

sudo apt-get install sun-java6-jdk

... but the ant still fails with the same message.

An LS of /usr/lib/jvm gives...

hi michelle, point JAVA_HOME to the jdk directory java-6-sun-1.6.0.15. (the jdk directory has to have a bin directory in it).

[msknight]

Superb, Janiii, that did the trick. I did the following...

Code: Select all

$ JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.15$ export JAVA_HOME

...and that did the trick. Many thanks!

[janiii]

nice to see you here around Michelle!
