I had the same issue on Ubuntu 10.04, and although the launch script is written differently -- the word "sun" does not appear in the 10.04 launch script -- the symptom was the same. Attempting to run jvisualvm caused: [[ $ jvisualvm Cannot find java. Please use the --jdkhome switch. ]]
The problem seems to be that jvisualvm is a symbolic link into the openjdk directory instead of the Sun JDK directory: [[ $ which jvisualvm /usr/bin/jvisualvm $ ls -l /usr/bin/jvisualvm lrwxrwxrwx 1 root root 39 2010-11-27 13:08 /usr/bin/jvisualvm -> ../lib/jvm/java-6-openjdk/bin/jvisualvm $ ls -l /usr/lib/jvm/java-6-openjdk/bin/jvisualvm -rwxr-xr-x 1 root root 2749 2010-05-03 04:31 /usr/lib/jvm/java-6-openjdk/bin/jvisualvm ]] However, I do have the Sun jdk properly installed: [[ $ which java /usr/bin/java $ ls -l /usr/bin/java lrwxrwxrwx 1 root root 22 2010-11-23 08:58 /usr/bin/java -> /etc/alternatives/java $ ls -l /etc/alternatives/java lrwxrwxrwx 1 root root 36 2010-11-23 08:58 /etc/alternatives/java -> /usr/lib/jvm/java-6-sun/jre/bin/java $ ls -l /usr/lib/jvm/java-6-sun/jre/bin/java -rwxr-xr-x 1 root root 47308 2010-09-15 04:41 /usr/lib/jvm/java-6-sun/jre/bin/java $ java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode) ]] My workaround was to explicitly use the --jdkhome option to explicitly specify the Sun JDK directory every time I run jvisualvm: $ jvisualvm --jdkhome /usr/lib/jvm/java-6-sun/ That made VisualVM work. -- visualvm fails to launch because it can't find jdk https://bugs.launchpad.net/bugs/657048 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
