Hello....

I have had not trouble with Java in Firefox previously. I had been
using Sun's Java versions 1.4.2 through the latest one 1.4.2_05
without problems. When 1.5 came out, I used the same procedure
that I always do and got rid of the old version, and installed the new
Java 5 (1.5) in the usual manor with the sym link in the plugin's folder.
Works perfectly for the FIRST time, but subsequently will lock up
Firefox (once a cache is created and a profile created). I have
done this repeatedly in two different computers and confirmed that it
just doesn't work correctly for me. Going back to the 1.4.2_05 version
is fine again. Just so you know, I have also tried things such as NOT
caching applets and changing all kinds of settings in the Java Control
Panel. I am using Firefox 1.0PR.

My question is twofold: What is the problems (has anyone else had trouble
with this new version...which by the way, works great in Windows and also
is WAY quicker in Linux, it seems)....

And second, what would be the advantage of going to the Blackdown
version (always a couple of versions behind) in place of the Sun
version (they are very closely related)?

Thanks in advance for any insight into this situation!

I am sorry that I cannot offer any help, but I have had exactly the same problem. I am using Ubuntu Linux with Firefox 1.0PR, and have gone back to java 1.4.2_05.

Same issue here with j2sdk-1_5_0, using Slackware current, Firefox 1.0.
Re-installed j2sdk-1.4.2_04 from Slackware 10 packages and all's well again...

But this IS a big help! This is the first confirmation that I have had that I'm not
the only one, so even though we don't have a solution yet, I thank you for a report.
I have been trying to find someone with the same problems for a week now.

Thank-you thank-you thank-you.

I will assume that others have had this problem as well. NOW, I feel confident to
go to either Mozilla.org and/or Sun with the problem and see if they have a fix...

I thought I was going crazy...

Thanks again

I'm glad it is helpful to you to know that others have had the same problem, I was also relieved to see that I was not the only one!

Found my mistake...
symlink in firefox plugins needs to point to /jdk1.5.0/jre/plugin/i386/ns7/libjavaplugin_oji.so , not /jdk1.5.0/jre/plugin/i386/ns7-gcc29/libjavaplugin_oji.so . I should pay more attention to upgrades, I guess...

Not my problem....Yes THAT would be a problem. Just for fun, I pointed to THAT one too, but
of course, it won't work at ALL. But MY problem is even when my sym link is pointing to the
CORRECT plugin file. See, it WILL WORK, but only for a while....if you close Firefox, and then
go BACK to the SAME PAGE, or another Java page, it will lock up, like it's always downloading.
Can't even close the program until IT decides that it's locked or you kill the process with a kill signal.

Hmmm....

I am using the JRE version, NOT the SDK version, but the virtual machine part is exactly the same....

Don't need the SDK for anything and it's awful top-heavy with stuff...
