Hi,
I need help running a dynamic web project using a j2ee preview server. When I run a test page it displays HTTP ERROR: 200 and I get the following error in the console:

Hi MrMiagi, I've seen your trace and I believe the error is caused by this message: (Caused by java.lang.NoClassDefFoundError: org/apache/log4j/Category).

That's means the server doesn't find de class org.apache.log4j.Category. Do you have the log4j.jar included in your project??

[MrMiagi]

Yes, I have already added it to my application's WEB-INF/lib folder and my JSF Library.

[netverde]

First of all, I don't speak english fine. I hope you understand me.

Please, review log4j.jar and find the class org.apache.log4j.Category. The log4j.jar depends of the commons-logging.jar. Maybe the two jars aren't compatible because they have differents versions.

[MrMiagi]

well, I'm using commons-logging.jar - version 1.0.4 and log4j.jar - version 1.2.8. I looked but I'm not sure what versions are compatible.

[netverde]

Hello, I've visited the commons-logging and log4j web page and the version are compatibles. If you want, you can probe a version more recent: for example, commons-logging 1.1.1 and log4j 1.2.15.

As I told you in last post, review log4j.jar. Find the class org.apache.log4j.Category. I'm sure that this class is not present in the jar file. You can extract all files as a zip file, using winrar or winzip (in windows OS, of course). Then find the class Category.class in the path org/apache/log4j.

Commons Logging - Overview

Apache log4j 1.2 -

[MrMiagi]

Checked my log4j.jar and it does have the Category class.
