Velocity-1.6.2.jar + Struts2: Unable to instantiate VelocityEngine! Please help!
Hi,
We are using velocity-1.6.2.jar and velocity-tools-2.0-beta4.jar with
Struts2 as view templates.
However, we get the following errors if we define result type to
"velocity". Any help would be greatly appreciated!!! --Renee

You need to comment the corresponding line in velocity.properties, or to
create an empty macro file and give it a correct path, like:
velocimacro.library = /WEB-INF/VM_global_library.vm
