How to upgrade jre selectively on linux mint

view story
linux-howto

http://stackoverflow.com – I have newly started using linux mint (linux at all). I have installed two jre versions on it. One openjdk and another oracle jdk. Here is how my update-alternatives --config java output says - There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode 1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode * 2 /usr/lib (HowTos)

I'm using a shared server.

Problem with java3d 31 weeks 2 days ago

I want to play this java simulation: http://www.compadre.org/OSP/items/detail.cfm?ID=9640 in java 3d mode on a linux (ubuntu) system. But it doesn't work.

If I switch to java 3d-mode it complains that java 3d is not installed. sudo aptitude install libjava3d-java didn't help.

Then I did a right click in this java app and selected Diagnostics-> About Java 3D.

I've got java-6-openjdk and java-7-openjdk running on Natty (11.04) on one machine and successfully toggle between them using update-alternatives --config java (or javac).

For some reason this doesn't seem to work on a second machine of identical spec.

Hello, the default java installation is openJDK.

/usr/bin/java -> /etc/alternatives/java /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

I want to install JDK 1.6, and executed this command:

Code: alternatives --install /usr/bin/java java /usr/lib/java/jdk1.6.0_45/bin/java 20000 But the symbolic link does change at all. What might be wrong?

I just installed Fedora 17. I'm setting up the Android Build Environment and need Java.

I downloaded and installed jdk-6u32-linux-amd64.rpm I ran

java -version

and it spit out the correct version.

Well a day or two later i tried my first compile in Fedora 17 and it complained about java and failed.

So I downloaded the latest version of Java from Oracle so I could get a 64bit JVM on Ubuntu Server 10.10. After extracting the file and updating the alternatives I went to check my installation by running java -version and I get this error: -bash: /usr/bin/java: cannot execute binary file

I'm at a loss for what to do here.

I searched askubuntu and tried the suggestions but failed .I try this question:How to completely uninstall/reinstall Java

1.I run sudo apt-cache search openjdk get the following:

openjdk-6-dbg - Java runtime based on OpenJDK (debugging symbols) openjdk-6-demo - Java runtime based on OpenJDK (demos and examples) openjdk-6-doc - OpenJDK Development Kit (JDK) documentation openjdk-6-jdk - OpenJDK D

Due to the new Java license, Oracle JDK was removed from Ubuntu repository and it doesn’t be hosted in the PPA. If you want to use Oracle Java instead of OpenJDK Java Runtime in Ubuntu.
