Java SE (Java Platform, Standard Edition)

Hello All,

I'm rather a newbie when installing Java on a (Suse) Linux system. I downloaded both the
jdk-1_5_0_05-linux-i586.bin
and
jdk-1_5_0_05-linux-i586-rpm.bin
files and installed them.

The first one had no noticable effect. In the end I copied he rpm to my /usr/lib/jvm directory and installed the rpm.

The result is that I have the following contents in the /usr/lib/jvm directory:
rwxr-xr-x 6 root root 424 2005-10-02 11:03 .
drwxr-xr-x 108 root root 34168 2005-10-02 11:03 ..
lrwxrwxrwx 1 root root 26 2005-10-02 11:03 java -> /etc/alternatives/java_sdk
lrwxrwxrwx 1 root root 32 2005-10-02 11:03 java-1.4.2 -> /etc/alternatives/java_sdk_1.4.2
lrwxrwxrwx 1 root root 23 2005-10-02 11:03 java-1.4.2-sun -> java-1.4.2-sun-1.4.2.05
drwxr-xr-x 6 root root 144 2005-10-02 11:03 java-1.4.2-sun-1.4.2.05
drwxr-xr-x 3 root root 72 2005-06-24 13:04 java-1.4.2-sun-1.4.2.06
drwxr-xr-x 3 root root 72 2005-10-02 10:46 java-1.4.2-sun-1.4.2.08
lrwxrwxrwx 1 root root 30 2005-10-02 11:03 java-sun -> /etc/alternatives/java_sdk_sun
drwxr-xr-x 9 root root 376 2005-08-27 03:34 jdk1.5.0_05
lrwxrwxrwx 1 root root 21 2005-10-02 11:01 jre -> /etc/alternatives/jre
lrwxrwxrwx 1 root root 27 2005-10-02 11:01 jre-1.4.2 -> /etc/alternatives/jre_1.4.2
lrwxrwxrwx 1 root root 27 2005-10-02 11:01 jre-1.4.2-sun -> java-1.4.2-sun-1.4.2.05/jre
lrwxrwxrwx 1 root root 25 2005-10-02 11:01 jre-sun -> /etc/alternatives/jre_sun

The JDK 1.5 is installed, but the links are not changed. Even the java from the bin directory is linked to the java of the 1.4 jre:
~> ls -la /usr/lib/jvm/jdk1.5.0_05/bin/java
lrwxrwxrwx 1 root root 22 2005-10-02 11:10 /usr/lib/jvm/jdk1.5.0_05/bin/java -> /etc/alternatives/java
~> ls -la /etc/alternatives/java
lrwxrwxrwx 1 root root 35 2005-10-02 11:01 /etc/alternatives/java -> /usr/lib/jvm/jre-1.4.2-sun/bin/java

What do I need to do to change the links? What do I need to do to change all (probably hidden) links all over my system?

Tia,
Michel
