Servers that only implement a J2EE Servlet/JSP runtime environment (e.g. Apache Tomcat) may need the additional libraries mail.jar, jta.jar and activation.jar (See installation instructions for the OpenWGA WAR-File Distribution) . These can be downloaded here.
Choose one archive file - both contain the same data - unpack the contained JAR files and add them to the"lib" folder of your Tomcat installation.
