So I followed the instructions on Sun's site and installed Java version
1.5. Installation appeared to succeed, but apparently Eclipse is still
looking at the old installation. How do I get it to look at the new Java
installation?
Thanks

Or rather, you might make sure the 1.5 Java is the default one.
Type
java -version
on the command line. It should say something like
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_03-b05, mixed mode)
Note that I already have java 1.6, which I would suggest you to take
too. No reason to use the old Java 5 anymore.
This means you will have to mess around with PATH and stuff. I supposed
you installed the new Java in /usr/local/, then it will suffice to put a
symbolic link to /usr/local/jdk<version>/bin/java in /usr/local/bin.
Alternatively, as root, type
update-alternatives -config java
on the command line and see whether it offers you your new version. If
not, you=E2=80=99ll have to add it somehow. I do not know how that works=
, though.
Even more possibilities: install it by your favorite package manager,
this should do all that stuff for you.

Better yet is to add that option to eclipse.ini, taking special care to
follow the correct format. There are many examples to be find via Google.
Hope this helps,
