Where is sun's jdk?

Question

i installed sun's jdk and i can't locate it.
In:

/usr/lib/jvm/java-6-sun/

is only jre, where is jdk?

Answer 1

Install sun-java6-sdk and it'll install the SDK. The SDK and the JRE are separate packages.

Answer 2

From a terminal, Confirm if the package is installed using.

sudo dpkg -l|grep -i sun-java6-jdk

List all the files installed by the package using

sudo dpkg -L  sun-java6-jdk

The listing of all files will help you to locate where directories/files installed by Ubuntu.

Answer 3

If you want to find out what is the default on your system you could do it like this.

ls -ltr /etc/alternatives/javac

It will list a symbolic link pointing to the default jdk of your system.

On my system the default is located at '/usr/lib/jvm/java-6-openjdk'. There is also an alternative jdk installed at '/usr/lib/jvm/java-6-sun'.

If there aren't any you will need to install the package 'sun-java6-jdk' as pointed out in some other post.

Answer 4

Mine in in /usr/lib/jvm/java-6-sun/

You can check yours via synaptic, select sun-java6-jdk, Properties

Answer 5

Try this command

update-alternatives --display java

This will list all java packages installed in your system.

Sample output:

java - auto mode
  link currently points to /usr/lib/jvm/java-6-sun/jre/bin/java
/usr/lib/jvm/java-6-sun/jre/bin/java - priority 63
  slave java.1.gz: /usr/lib/jvm/java-6-sun/jre/man/man1/java.1.gz
Current 'best' version is '/usr/lib/jvm/java-6-sun/jre/bin/java'.

Hope this helps.
