Ubuntu + Java 7

[Maneesh Godbole]

I just rigged up an Ubuntu 1010 VM. I plan to try out Java 7.
Anyone got Java 7 running on Ubuntu? Any feedbacks?

[Peter Johnson]

OK, so you piqued my interest. I installed JDK 7 on my Ubuntu 11.04 VM and used it to run a few things (Eclipse, Maven, Tomcat). Worked fine for me.

[Maneesh Godbole]

Is that Open or Sun JDK?

[Peter Johnson]

That was the Sun JDK.

I was hoping you would say that. Thanks
Now to get cracking on my installation.

Recently updated version of Java on a Windows PC to version 7 and JDownloader works great. Then update Java 7 on Ubuntu, but when you try running them JUpdate JDownloader or crashes. And is not executed. Shows a problem of lack of a file in the installation of Java. I run other Java applications and work perfectly. The funny thing is that in Windows works perfectly JDownloader. The version of Java 6 did not present that problem. I hope I can say it is. Not to return to Java 6. Thank you.

I tried installing the sun java 7 jdk rpm by following instructions for converting it to a deb and then installing. I then tried to set the alternative config to the java 7 installation. Java 7 did not appear on the list.

Now I'd like to follow sun's instructions. As a first step, it wants me to uninstall the other versions of java. I don't know how to do that. Can't even find them. (I guess I don't have to say that I'm relatively new to Linux now.)


By the end of this discussion, I'm hoping to have sun java 7 (jdk / jre) properly installed and operating as the default. - Thank you.
