Keeps referencing wrong version of java

[buzzterrier]

I installed the latest rpm from sun

lrwxrwxrwx.  1 root root   16 Mar 13 11:58 default -> /usr/java/latest

drwxr-xr-x   9 root root 4096 May 15 08:44 jdk1.6.0_25                                                                                                                                                                         
lrwxrwxrwx   1 root root   21 May 15 08:44 latest -> /usr/java/jdk1.6.0_25

I have my .bashrc JAVA_HOME pointing to /usr/java/latest

But when I do a java -version I get:

java version "1.5.0"
gij (GNU libgcj) version 4.5.1 20100924 (Red Hat 4.5.1-4)

The other odd thing is that in package manager, openjdk 5 does not exist, and openjdk 6 is not installed. So I am baffled as to how it is using this version of java. Any ideas??

[buzzterrier]

looks like 1.5.0 was installed by default and is being managed by alternatives. So even though I had simlinks pointing to my jdk it was still using alternatives to manage the active java version. I installed my jdk to alternatives and made it active and it worked. Wish they would just automate this.

So, when you execute the command "ls -l /usr/bin/java" where is the link pointing to? My guess is that as buzzterrier says, it will be pointing to /etc/alternatives/java instead of /usr/java/default/bin/java.

[buzzterrier]

correct, it is pointing /etc/alternatives/java

Slowly getting the hang of this linux thing!

Hi,
You may try to uninstall the java machine, clean up all java things from the computer (the components of the integrated software environment I mean) and reinstall it back again.
I personally would prefer to work with the java package that is listed in the repository list of the linux distro (1.6 as far as I can see), rather than downloading from the net packages with unknown risk.
Actually the error may be insignificant and if you try to connect to the java guys from sun they may be able to fix it 'as it is at the moment'.
The good news is that you have options and the bad news is that you have to decide to choose one (at your own discretion).

Try putting the path to java 1.6 in the front of the path statement.

PATH=/usr/java/jdk1.6.0_25/bin:$PATH
export PATH

Hi,

Check up what you have on your computer.
$ rpm -qa|grep java
$ rpm -qa|grep jdk

These commands list the compiled packages of java and jdk respectively.

Then check up which of the packages are installed and connected to the system:

$ rpm -q java
$ rpm -q jdk

If it lists one and the same package as 1.5 and 1.6, erase the 1.5 version:
$ rpm -e java-1.5

If it lists 1.6 but it is not installed, erase 1.5 (if any) and install the 1.6.

If this gives a message 'Package java-*/jdk-* is not installed' - install the 1.6 if available, and if not - the 1.5 one.

Maybe the system is not able to install the 1.6 for you have compatibility layers to CJI on 1.5.

You may also try to Navigate to Add/Remove Software from the Desktop menu and in the search box to write: java
... and after that: jdk

to see which of the packages are installed and which are not, which is 1.5 and which 1.6.
In my repo some of the java packages are 1.5 and some are 1.6.

If you come to a 'Dead End Street' ask the guys from Sun or the developers of your linux distro how to proceed.
