Hi Ashley,
I think there is no version of log4j in the classpath :-) Eclipse
manages the classpath for each project, which means you can have
log4j-1.X for one project and log4j-2.X for another project.
Nevertheless you have to include the lib in the classpath. Here is a
short how to:
Create a folder 'lib' in your HelloWorld project.
Copy the log4j_1.X into it.
Right click on the project in Eclipse and select refresh.
Again choose from the project context menu the item properties.
Navigate to JavaBuildPath.
Under the 'library' tab click add jar and choose log4j.
Close the properties window.
Open the build.xml file.
Locate the line:
<lib dir=".">
<include name="Add .jar's that should be copied in the woa."/>
<exclude name="**/*.woa/**"/>
</lib>
And change it to:
<lib dir=".">
<include name="lib/*.jar"/>
<exclude name="**/*.woa/**"/>
</lib>
The change in the build.xml makes sure that the lib gets in the woa and
the app classpath. Which means you can deploy the app without coping
any jars. This stuff is also available in the WOLips help. :-)
