I have a Debian Unstable VM which I used to package a Java project before. Today, the javac was gone somehow, so I installed default-jdk again. But still, there is no javac.

What could I do?

javac is managed by the alternatives system. /usr/bin/javac is a symbolic link to /etc/alternatives/javac which is a symbolic link to one of the Java compilers you have installed. The default-jdk package depends on openjdk-6-jdk which provides /usr/lib/jvm/java-6-openjdk-i386/bin/javac (on i386). This file is what /etc/alternatives/javac should link to. If it doesn't, run

update-alternatives --config javac

to configure the target of /etc/alternatives/javac interactively, or update-alternatives --auto javac to reset it to its default value.

  • I tried running update-alternatives --config javac, but it gave me update-alternatives: error: no alternatives for javac.. I just created the symlink by hand. – Martin Ueding Nov 27 '11 at 13:11

Check your $PATH environment variable to check if it contains /usr/lib/java/bin or /usr/lib64/java/bin on x86_64 systems. This variable is usually when you log in set via a shell script that the jdk package installs; it may help to log out and back in again. Check the value of $JAVA_HOME.

If your PATH does contain the path I mentioned, and type javac still doesn't give you anything, then try typing locate bin/javac and see what that returns. You may have to run sudo updatedb or sudo locate -u beforehand, if you just installed the package, so that the slocate database is up do date.
