Jar utility and log4j

[alexandros]

Hi, everyone.

I'm new to java and I have this utility java project in Netbeans to which I want to add log4j. The log4j jar is not getting packed inside the utility when this one gets built. Either way I wouln't know where to put it.
A

NoClassDefFoundError: org/apache/log4j/Logger

message is thrown every time I try to run the main class. I do have the log4j.xml inside the utility JAR, in a default package/folder.
I run the utlity with classic java -jar.

Any help would appreciated.

Thank you.

The log4j jar needs to be on the classpath when the program is executed. One way is to use the manifest file's Class-Path: entry with the log4j jar.

Hi, thank you for your response.

My MANIFEST.MF says:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 1.6.0_01-b06 (Sun Microsystems Inc.)
Main-Class: dc.decisor3Batch.util.BatchCopier
Class-Path: . lib/log4j-1.2.16.jar
X-COMMENT: Main-Class will be added automatically by build

And when I unzip the utility jar there are META-INF, dc, lib folders and log4j.xml

lib folder has the log4j jar

When you execute the command: java -jar THEJARFILE.jar
does the folder that holds the file: THEJARFILE.jar contain the lib folder that contains the log4j-1.2.16.jar file?
