I'm trying to transfer to 64 bit Ubuntu 12.04 from 32 bit Ubuntu 12.04.

ADT for eclipse and the Android SDK requires 32bit Java but I would like to keep the 64 bit Java that I just got installed to run with NetBeans. Is there any way to install the two side by side using apt-get or will I have to manually install the 32 bit JDK?

this is the script i am trying to use to set the path to the 32 bit JDK:


#Set version JDK 32


this is the result of running it:

enter image description here

so i manually entered each command from the script then started eclipse and got this error:

JVM terminated. Exit code=13
-jar /usr/lib/eclipse//plugins/org.eclipse.equinox.launcher_1.2.0.dist.jar
-os linux
-ws gtk
-arch x86_64
-launcher /usr/lib/eclipse/eclipse
-name Eclipse
--launcher.library             /usr/lib/eclipse//plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.dist/

-vm /opt/jdk1.7.0_25-i586/bin/java
-jar /usr/lib/eclipse//plugins/org.eclipse.equinox.launcher_1.2.0.dist.jar

In your case, I would recommend using the the JDK tar.gz packages (x86 and x64) from OTN and extract it to a preferred directory, using a quick shell script to switch JDK versions, e.g.

#Set JDK versions

Another popular way to install JDK (kind of automated but a bit time consuming)

The most popular way NOW is:

NOTE: it builds .deb from OTN binaries and set up a local repository, install from there.

You can run update-alternatives --config java and see installed JDK/JRE and configure.

To be able to use 32-bit JDK on 64-bit Linux

You need to install the 32-bit shared libs (now Ubuntu uses something called Multi-arch).

If you don't have ia32-libs installed, you'll get File NOT FOUND error when running 32-bit java.

terry@tux:/opt/jdk1.7.0_25-i586/bin$ file java
java: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, BuildID[sha1]=0xb4f81805640a786538c721d745f97f3485d03e3c, not stripped
terry@tux:/opt/jdk1.7.0_25-i586/bin$ ./java
bash: ./java: No such file or directory

That's probably why the shell script didn't work.

NOTE: the script did do its job, see which output

terry@tux:/opt$ source 
terry@tux:/opt$ which java

so i would have two scripts and run one or the other depending on which jdk i want to use? –  John Jul 29 '13 at 1:46
You don't have to. You can set the preferred JDK, .e.g. 64-bit in your ~/.profile or ~/.bashrc and the other using a script. –  Terry Wang Jul 29 '13 at 21:13
thank you, testing it now –  John Jul 29 '13 at 21:20
still getting the same error in eclipse –  John Jul 29 '13 at 22:46
how can i tell if the path is set correctly after the script –  John Jul 29 '13 at 22:46
