Does one needs gcc java in fc4

[Vikram Goyal]

Hi,

I am running a java application which expects the sun jre to sucessfully
execute itself. I have these rpms from default installation:

1} java-1.4.2-gcj-compat-src-1.4.2.0-40jpp_31rh.FC4.1
2} java-1.4.2-gcj-compat-devel-1.4.2.0-40jpp_31rh.FC4.1
3} gcc-java-4.0.1-4.fc4

Do I need these and how do I circumvent these.

I have sun's jre version jre-1.5.0_05-fcs installed

Thanks!

I assume that jre-1.5.0_05-fcs is not a rpm. What we do is install it
somewhere on the /usr/local tree and then make the directory with the
executables available by putting it ahead of /usr/bin in the PATH
search order.

Try this:

Download the Sun JRE 1.5 (preferably J2SDK 1.5 if you're a
developer) and install it, i.e., in /opt. You may want to download
the `.bin` rather than the `.rpm` to have more control as to
where you want to move it after you `sh` it.

Then set your JAVA_HOME variable (either in /etc/profile [global] or in
~/.bash_profile [user]) to point it to the directory where you
installed/moved it. Modify your PATH variable, in such a way that
JAVA_HOME comes first before everything, to override java-gcc
path.

JAVA_HOME=<install_dir>
PATH=$JAVA_HOME/bin:$PATH:<etc>

HTH.

I found a more elegant solution from the list. See..

Using alternatives to setup the system to use the Sun version is better
than removing all the Java packages. See
http://fedoraproject.org/wiki/JavaFAQ

Is the more general concept of alternatives documented somewhere?

In its man page.
