Now to create the new (corrected) alternatives file for java type the following commands as root (modify for jdk as needed);
usr-sbin-alternatives --installusr-bin-java javausr-lib-jvm-jre-1.4.2-gcj-bin-java 1
usr-sbin-alternatives --installusr-bin-java javausr-java-j2re1.5.006-bin-java 2

usr-sbin-alternatives --config java
You should now see for example:
There are 2 programs which provide 'java'.
Selection Command ----------------------------------------------- 1 usr-lib-jvm-jre-1.4.2-gcj-bin-java *+ 2 usr-java-j2re1.5.006-bin-java
Enter to keep the current selection+, or type selection number:
In the example above java is already configured correctly *+ 2 to use Sun's Java, no changes are needed, just press the Enter key here. If you have been following the instructions then you should have the same results (version numbers may be sightly different).
Now type;usr-sbin-alternatives --display java
You should see for example;
java - status is manual. link currently points tousr-java-j2re1.5.006-bin-javausr-lib-jvm-jre-1.4.2-gcj-bin-java - priority 1usr-java-j2re1.5.006-bin-java - priority 2 Current `best' version isusr-java-j2re1.5.006-bin-java.
Next you might want to create (or edit)etc-profile.d-java.sh file, example below;
export JAVAHOME="-usr-java-jre1.5.006-bin" export JAVAPATH="$JAVAHOME"
When done creating or editing the file type;
sourceetc-profile.d-java.sh
Now any user root or other wise should be able to use the command;
which java
and the results should read something like;
usr-java-jre1.5.006-bin-java
Also any user root or other wize should be able to use the command;
