Chapter 5: Fixing Java and ANT
Removing default Java
The default java installed for Fedora Core 4 MUST be removed. It will not work with the Globus toolkit and it is easier and less troublesome to remove it entirely.
First see if the default java is installed:
[root@nodeB ~]# which java
/usr/bin/java
That file is usually a symlink:
[root@nodeB ~]# ls -alh /usr/bin/java
lrwxrwxrwx 1 root root 22 Oct 7 16:06 /usr/bin/java -> /etc/alternatives/java
That link is actually a link to the actual binary:
[root@nodeB ~]# ls -alh /etc/alternatives/java
lrwxrwxrwx 1 root root 35 Oct 7 16:06 /etc/alternatives/java -> /usr/lib/jvm/jre-1.4.2-gcj/bin/java
You can use 'rpm' to query and see which package actually owns the binary:
[root@nodeA ~]# rpm -qf /usr/lib/jvm/jre-1.4.2-gcj/bin/java
java-1.4.2-gcj-compat-1.4.2.0-40jpp_31rh.FC4.2
With the name of the binary package known, use yum to remove it:
Note that the yum remove command should be the entire file name WITH extension. In some cases this may end with a reference to FC4, but not always.
[root@nodeB ~]# yum remove java-1.4.2-gcj-compat-1.4.2.0-40jpp_31rh
Note that this will remove a fair number of packages, but that is ok (and desired). You might see output that looks like the following:

Complete!
Now check to make sure that the default java is gone:
[root@nodeB ~]# which java
Note: The following code appears on multiple lines, but it is 'one' line of code
/usr/bin/which: no java in(/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/
local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin)
[root@nodeB ~]# ls -l /usr/bin/java
ls: /usr/bin/java: No such file or directory
