I had that problem with the j2ee plugins, I've solved using netbeans win
sun java :D (and we even had no icedtea then)

But seriously, you could install a different copy of the eclipse ide if
it is what you need, as well as the jdk. I think that the latest icedtea
are quite complete to run almost any java program. In all these cases,
it's as easy as a

* yum update --enablerepo=development icedtea*
or
* download jdk6u4 rpm and the jpackage java-1.6.0-sun-compat and rpm
-Uvh them
or
* tar xvfj the eclipse bundle you need into /opt

But it has the added value that it's easier to setup the server side of
things, the various classpath, etc... compare it with a windows
environment, that is such an hostile platform for development...

Also, consider submitting bug reports for your specific problems.

You can choose what is the system default with the Java Toolset
application (or using the alternatives system). I'm using the system
defaults mainly, but using the command line tool it's just a matter of
firing:

/usr/sbin/alternatives --config javac
/usr/sbin/alternatives --config java

Hope this help,
Mario
