Problem with openjdk

English Programming/Scripting
1

Hi everyone!
I have just performed a clean install of opensuse 13.2 (kde).
Now i need to use the java jdk.
If I use the command “java -version” I have this result:


antonio@linux-3apr:~> java -version
openjdk version "1.8.0_40"
OpenJDK Runtime Environment (build 1.8.0_40-b10)
OpenJDK 64-Bit Server VM (build 25.40-b14, mixed mode)

But when I try to use the command “javac -version” I have this result:


antonio@linux-3apr:~> javac -version
If 'javac' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf javac

And the output of “zypper se jdk” is:


antonio@linux-3apr:~> zypper se jdk

Now I don’t understand why I have both version 1.7.0 and 1.8.0, and why the command javac don’t work.
Please help me, I need java to work as soon as possible!

javac is included in the devel package; java-1_8_0-openjdk-devel

You can have both 1.7 and 1.8 installed at the same time and switch between them with **update-alternative --config java
**
There are use cases where you might need both.

Thank you Miuku for the answer :slight_smile:

So do you think it’s enough to install the 1.8.0 version or it’s better to install both 1.8.0 and 1.7.0?

4

If you have no specific need and your applications are fine with 1.8.0, just use the latest one.

Ok, I have just installed the devel package:


antonio@linux-3apr:~> javac -version
javac 1.8.0_40

Thank you very much for your help!

Ps: Opensuse rocks!!! :slight_smile:

No prob.

I made a typo there, it’s update-alternatives, not update-alternative. In case you need that someday in the future :slight_smile:
