133637 - Class nodefined error

Status: RESOLVED WORKSFORME

(Core Graveyard :: Java: OJI, defect)

Description

[Steve Wardell]

This seems to be a platform parity error. Using the above URL on Windows will
load the applet (in 0.9.9 and current builds). However, on Linux the 0.9.9
release will not load this applet giving a class not defined error.

What do you mean?

Applet loads for me (no exceptions are raised in java console)
Then i see popup window with "your session is expired".
Is it the same for you?

I am using recent trunk build with Sun's jre 1.3.1.
What is yours java plugin version?

This is on Moz 2002031416 on Linux. The behavior you experience is what I have
happen on Windows platforms. Java Console information below:

Try to set trace level to 5 and reproduce the problem.
Please post java console output here.

Well, this seems to work on 20020328 build on Linux. Unfortunately, next Redhat
will ship with 0.9.9 so this is bad. Anyone have an idea what bug might have
fixed this problem between 0.9.9 and now?

Comment 6

[Igor Nekrestyanov]

Sorry, I have no idea what was the reason of this problem.
If you really want to isolate the fix and apply it to RedHat's mozilla  
then i suggest to check builds of mozilla between 0.9.9 and now 
to isolate the time when problem was solved. 
However, it could be resolved by fixing several other bugs.

Mozilla 1.0 will be available soon - so i do not think 
backport of patch to 0.9.9 worth it.

Anyway, because this bug is fixed in trunk i am gonna to close it.
Please, reopen if problem is reproducible with recent trunk builds.

Comment 7

[Christopher Blizzard (:blizzard)]

This is still present in 1.0.1.

Comment 8

[Steve Wardell]

Blizzard: This downloads an applet from our company's servers and things had
changed since. I've updated the test page, so please re-test.

[Kenneth Herron]

I'm using linux nightly 2002111904 with sun's java 1.4.1. I'm getting the same
behavior described in comment #1. My java console contains the following:

------------------------
Trace level set to 5: basic, net, security, ext, liveconnect ... completed.

------------------------

I gather this is the intended behavior. Steve, can you try to reproduce this
with a current copy of mozilla?

[Steve Wardell]

Works for me on 20021017 build of 1.2 beta on Redhat 7.3. Looks like it got
fixed in the last 7 month sometime.
