error when posting

[Migrated From Jforum.net]

I get this error when trying to post.
Previsualisation does the same.

One user reports having the same when trying to modify his profile (but seems to have successfully post)

Restarting the context doesn't help

java.lang.reflect.InvocationTargetException: org/htmlparser/lexer/InputStreamSource (Local variable name has bad constant type)

any Idea ?

It happens when posting anything in any place. But it only happens with specifics users (which were able to post before).

Its like something might be corrupted in the database.

It happens also when I try to modify password throw the profile even with admin user.

the forum is at www.woltar.com/forum I'm not sure you will be able to reproduce the problem since it is user specific.

me again

It seems that the bug is user-connected. I tried posting anonymous and created a new user, it worked fine.

Hi,

this error occurs with any input? I mean, it seems that is something wrong with the charset manipulation, or something like that. Is the forum available to the Internet, or in some place I can test it?

Which Java version? I compiled JForum with jdk 1.4.x ( .1 or .2, I don't remeber right now ).. This error often occurs when the classloader finds some "incompatibilities" in the .class file.

Thanks.

Damn, I just can't understand a single word of French

Well, I'll try to find some way to reproduce the error. If you could get some info about the users whose are getting this error, it would help a lot ( information like "signature", for example.. maybe the error is associated to some character set or "special char".. )

I really don't think so. I'm own user has this problem, I didn't change my profile from the moment I was able to post and the moment I wasn't anymore.

I just tried something else: go to my profile page, don't change anything, click validate... same error.

If you copy past, beware of trailing spaces.
Or could it be a charset/UTF8 problem?


Anyway you can create your own account and test changing your profile.

OK, I manage to log in :P

The reason why I couldn't log in just now is because I tried the username/password at JForum ops:
I should have read the earlier posts

any guess on what the cause might be? It seems to propagate to more and more users.

I even tried to switch back the site to english in case of..

FYI, I upgraded from RC4 applying the upgrade to the database
RC4-to-RC5 then RC5-to-2.0
Yet the site worked well just after the upgrade.

I had also a few crash of the jvm, maybe it left the database in a corrupted situation....
speaking of that, I'll look repairing the database with mysql tools, who knows.

That's because the htmlparser was introduced in 2.0 .

hm, I don't think it is related to the database, but to the htmlparser library.. It looks corrupted. Can you get it from http://htmlparser.sourceforge.net/ and override the jforum's one? Or, better, try first to get it from the jforum-2.0.2.zip file and replace with the current version at WEB-INF/lib .. Then, if it not work, you can get it from htmlparser.sf.net and compile it from strach and see if it works then.

Is there a possibility to to this?

ok I try all that

Well, hum, that'weird

Before doing what you suggested, I check the lib form the very zip
I took it from Jforum-2.0.1.zip and the one which was in production.

They were not the same!! (using unix diff)

size date were the same although.

I just copied the original one to replaced the corrupted one, now it seems to solve the problem.

Weird thing is when why how it got corrupted. Since the forum worked quite fine for a few days after the upgrade to 2.0.

Anyhow, probably more an OS/Hardware question.
