Hello,

I created a simple web application and added log4J's jar in my lib folder and it seems to work fine. Then i created a Ejb module and did the same thing of adding jar file in my classpath, but i am getting this error :-

I don't even have any other version of log4j in classpath. Any idea why is this error coming?

Actually first i created a Enterprise application and everything seemed to work fine. But then, i copied files from my enterprise application's ejb module to a separate module and since then these errors are coming. This is in my build-impl.xml :-

<target depends="compile" name="library-inclusion-in-archive">
        <copyfiles files="${libs.Log4J.classpath}" todir="${build.classes.dir}"/>
    </target>
    <target depends="compile" name="library-inclusion-in-manifest">
        <copyfiles files="${libs.Log4J.classpath}" todir="${dist.ear.dir}/lib"/>
        <manifest file="${build.ear.classes.dir}/META-INF/MANIFEST.MF" mode="update"/>
    </target>

Don't know why is this pointing to ear instead of jar. Is there any problem with the above statement? How do i resolve this? I am using Netbeans 6.8

Thanks in advance :)
