Installing Oracle JDK on Xubuntu64 11.10 crashes

[sejens]

Hi!

I'm trying to install the Java JDK with Netbeans on XUbuntu64 11.10.

I've got the file jdk-7u2-nb-7_1-linux-ml.sh from http://www.oracle.com/technetwork/java/javase/downloads/jdk-7-netbeans-download-432126.html (http://www.oracle.com/technetwork/java/javase/downloads/jdk-7-netbeans-download-432126.html)and I try to install it like this:



jens@acer13:~/Hämtningar$ ls jdk*
jdk-7u1-nb-7_0_1-linux-ml.sh jdk-7u2-nb-7_1-linux-ml.sh
jens@acer13:~/Hämtningar$ sudo ./jdk-7u2-nb-7_1-linux-ml.sh
[sudo] password for jens:
Configuring the installer...
Searching for JVM on the system...
Preparing bundled JVM ...
Extracting installation data...
Running the installer wizard...

Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "main"
jens@acer13:~/Hämtningar$ ^C
jens@acer13:~/Hämtningar$
This worked when I ran XUbuntu32 11.10. However in order to be able to use the OPA programming (http://opalang.org/faq.xmlt) language I needed to switch to 64 bit. However, I still want to be able to program in Java...

Any ideas why the installation of the JRE crashes?

Thanks
Jens

You can install the open JDK straight from the Ubuntu repos, by typing the following into a terminal:


sudo apt-get install openjdk-7-jdk

That's assuming that you want Java 7, if not replace the 7 with a 6 in the command. Similarly, Netbeans is also available from the repos, and you can find it in the software centre

Thanks.

Will that give me Netbeans too? And what's the difference between open JDK and Oracle JDK?

I'm very tempted by this bundle since I worked in that environment before (Oracle JDK + NetBeans).

Yeah netbeans is easily available too... to install it all in one lump, type the following into a terminal:


sudo apt-get install openjdk-7-jdk netbeans

The Open JDK differs from the Oracle one by the fact it is open-source (the source code is freely available). I believe that Oracle are moving toward the openJDK anyway (someone correct me if I'm wrong), check out this wikipedia page (http://en.wikipedia.org/wiki/OpenJDK) for more info if you're interested.
