Install of JBuilderX interferes with execution of Java on internet.

When I install JBuilderX on my windows XP, it disables my ability to run Java programs at other internet sites.  For example, when I log into Capella's learning programs I get man internet errors and the pop-up Java menus no longer pop-up.
Also when I attempt to run applets using my internet explorer 6.0.2, the applet hangs and only a gray screen appears.
When I uninstall JBuilderX then the internet java programs work and I can run applets again outside of JBuilderX.
When I am using JBuilderX all of the features in JBuilderX work OK.
JBuilderX is adding some registry entries that get undone when I uninstall.  I am studying Java and I would like to be able to use JBuilderX and have my Java internet programs also work.  I have looked on Borland website and installed latest JBuilder patch 3, but this did not help.
Does anyone know of a solution to this problem?

It seems to be that JBuilderX interferes with the current java plugin you have. IS there a possibility (option while you install pluging) to change the default settings? Otherwise you might have to uninstall the current java plugin you have and install the one that comes with JBuilderX.

How do I change the java plugin to match JBuilderX?  How do I find out information about what java plugin is installed and look at default settings?

It depends on what browser you are using. On Opera I can open the java console and see info about the plugin I use (vendor, version etc).

You can always try to uninstall your current plugin and try to only use JBuilderX but that's a bit risky. Can you try installing JBuilderX on another computer (that does not have a plugin) and see if that works?

I'd try;

1) Uninstall plugin
2) install JBuilderX
3) Install plugin

that should work :-)  JBuilder uses the jdk inside the JBuilder folder, but you can specify any other 1.4 (and below) jdk to compile with instead..

That said, I have never had any problems installing JBuilder on my machines :-/

On my home computer running XP, I have Interent Explorer 6.03, and I have java console, java logging and JIT checked in the internet options.  I think I installed a java plugin from sun over a year ago.  My work computer is running windows 2000 and also has IE 6.02.  On the work computer, I have just JIT checked.  My work computer can run the Capella java software fine over the internet.
I will try unchecking the java console and java logging Internet options at home, then I will install JBuilderX and see if I can run the Capella software on the internet.   The only reason I installeld the java pluginn from sun was because I was concerned that the computer would not be able to run java code on the internet without it.  But this does not seem to be true.

I made some progress tonight.  I uninstalled Java 1.4.1 which I already had on my computer.  And I also uninstalled JBuilderX.
Then I reinstalled JBuilderX.  Now I can run programs over the internet at my work site and also at my school.  The problem with the programs not running right may have been due to my having two versions of java on my computer. I was told today that this can cause problems with Internet Explorer.  The JBuilderX comes with jdk 1.4.2_01 which is newer than what I had before.

One problem remains.  And that is that I can no longer run sample applets that are on my computer from my Internet Explorer.

I spent a lot of time trying to understand this problem doin research on Borland and Sun.
It turns out that the problem was a simple one to solve and the advice I have been getting here was good.
It turns out that two versions of JAva 1.4.1 and 1.4.2 were causing my IE to not work well.
When I uninstalled Sun 1.4 using standard Add/Remove and installed only Borland JBuilderX, then I had no more problems with IE (Internet Explorer).   But my applets that I had written would no longer work.  Then I decided to install Sun 1.4.2 (and this installed the 1.4.2 plugin).
This enabled my applets to work,  my Internet Explorer still works and Borland JBuilderX still works.
Thank you for your help.
