What is the equivalent of the following jdk path in Ubuntu 8.04?

I got to setup the following two variables:

export LD_LIBRARY_PATH=/usr/java/jdk1.6.0/jre/lib/i386/:/usr/java/jdk1.6.0/jre/lib/i386/client/:./
export JAVA_HOME=/usr/java/jdk1.6.0/

Since, the above is for the version of JDK installed via SunJDK, what could be the equivalent path for the openjdk-6-jdk package?

My OpenJDK is installed at:

/usr/lib/jvm/java-6-openjdk

I couldn't find the folder i386/, though. To which path should I point?

Solution

  • The open-jdk package itself does is not distributed with any shared objects/libraries (.so files) on Hardy, although open-jre does.

    Normally you need not set LD_LIBRARY_PATH manually, as the java binaries should automatically seek any standard open-jre libraries at their well-known locations. If, however, you are encountering issues with library dependencies (see how to use the ldd command to identify such unmet dependencies, below), you may need to point LD_LIBRARY_PATH to either /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/ (IIRC Slicehost's architecture is AMD 64bit) or /usr/lib/jvm/java-6-openjdk/jre/lib/i386/.

    Also export JAVA_HOME as /usr/lib/jvm/java-6-openjdk

    You may confirm that java satisfies all shared objects/libraries dependencies by running:

    ldd $JAVA_HOME/bin/java

    For a complete list of the files distributed as part of open-jdk and open-jre, see the open-jdk (amd64) file list and the open-jre (amd64) file list, or run:

    dpkg -L openjdk-6-jdk
dpkg -L openjdk-6-jre

    ...on your system.
