    That is expected. WOLips does not add these automatically. Or, at
    least, I am not aware of how to do this.

    Yes, they need to be there or in a "special" directory like:

    What I have done in the past is to edit the build.xml for the
    woframework or woapplication target and add a section like this:

                                <lib dir=".">
                                    <include name="mail.jar"/>
                                    <include name="activation.jar"/>
                                    <include name="JavaMailDocs.zip" />
                                    <exclude name="**/*.framework/**"/>
                            </lib>

    There might be a better way to do this in more modern versions of
    WLips, but I have not looked for it.
