How do I find the path to the 32bit version of java on 64bit Linux?

Question

I've installed a 32 bit version of java on my 64bit system to get Juniper VPN to work. What command line command will allow me to find the path to the 32 bit version of java?

Answer 1

You should be able to see all available java executables using the update-alternatives tool. For example, on my system:

$ update-alternatives --list java
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
/usr/lib/jvm/jdk-7-oracle-x64/jre/bin/java

Alternatively, you could also just search through /usr/lib for executable files called java:

$ find /usr/lib -name java -type f -executable
/usr/lib/jvm/jdk-7-oracle-x64/bin/java
/usr/lib/jvm/jdk-7-oracle-x64/jre/bin/java
/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
