Bug while posting message with BB code

[Migrated From Jforum.net]

Hi all !

I'm using JForum 2.1.4 with Tomcat 5 (on Linux Fedora Core 4) and PostgreSQL 8 database.

I've an error when I try to post (or preview) a message containing some BB code

(like [b] [/b])

for example.

The error is :

Looks like a weird problem:

The error message seems to indicate a problem with the regular expression used to detect "code" blocks, which happens suspiciously to be the first regular expression in the list.

I came to this from:...

Caused by: java.util.regex.PatternSyntaxException: A l'index 1 dans le mod̬le d'expression r̩guli̬re:
 quantifieur (?*+{}) sans ̩l̩ment pr̩c̩dent
         (?s)\[code\](.*?)\[/code\]
          ^

However, the expression is correct and it can be compiled and used with java.util.regex package using JDK1.4, at least on my machine...

��What is your JDK version?

In your post above, is the forum system (here) processing your "code" tags? It's hard to tell what you're having a problem with.

For example, is your problem happening when you try to process "code" segments with other bbcode segments contained within?

Maybe you could give us a detailed verbal description. I haven't had such issues myself, but perhaps I haven't "triggered" it yet.

I've installed the sun-jdk-1.5 and all seems to work perfectly now !!!

Thanks for your help !

Good to hear. It might be it was a classpath conflict problem, so if you have time, you might want to check if you have old JDK installations lying around, just in case ;).
