HELP

[kennethadammiller]

For those that want to say that I ask to much rather than look things
up myself... well, sorry. I've researched really hard, but I feel
like the information is between the lines, and I need someone who
knows. It will be much harder to go research this without asking
somebody, costly in time that is. And besides that's what these groups
are for right?

Before my 9.10 install, which went well, I was using an old version of
eclipse that I had added from the add/remove to make some programs. I
needed Visual Editor to make some things and when I tried to install
it, it kept giving me some null pointer exception or pointer not found
exception. I had to go post an error log and get on ubuntu irc channel
to find out that I need to be using a different Virtual machine for
eclipse and that I needed to update eclipse. well I upgraded my distro
and found that when I added eclipse from the add/remove, it wouldn't
let me add the visual editor either. I removed it and then added it to
my system following these instructions-

So i left VE alone and started to import my old source files, and I
kept getting some error any time I tried to test run that I couldn't
find the main class. I tried copying everything from the workspace to
my desktop to back it up, so I could systematically delete the
projects and recreate them. This still kept coming up with errors.

Through all of this I am facing numerous related issues. I really need
advice.

Things I would like answered from curiousity...
Should I even still use eclipse?
why did the people who manage the add/remove not update the eclipse
thing to say something or have a recent edition? (and who manages the
add/remove in the first place?)
why is there more than one type of VM?
What is the difference between J2SE and J2EE? (i know what the letters
stand for...)

The most important part though is the issues:

I still need VE for eclipse. it won't add. I don't know why.
Sometimes when I click a button, in any dialog of eclipse (the actual
editor's dialog panes that is), the buttons go down, but do nothing.
this is causing a lot of problems
How do I install the VM that is compatible with eclipse? If I do this,
what will happen to the one that netbeans uses, if I should decide to
use netbeans?

Guys thanks a lot.

And anyone that wants to can check out my program when I'm finished.
it's going to be really cool :):)
I'm nearly done, as soon as I get these problems out of the way, I can
get back to work on it. Thanks in advance, and let me know if you're
interested.
