Configuring Tomcat

Create the OpenWGA Configuration Directory

Create a directory where wga will store it's configuration and designs. In this example it is D:\wga

Disable tag Pooling (only necessary for OpenWGA 5.0 to 5.2)

If you are using Sun/Oracle Java you should also force Tomcat to use the Server VM:


In the final configuration step you need to add a Java Option to configure the OpenWGA configuration directory.
