Using Ant to pre compile jsp's

Hello,

I'm trying to compile my jsp's at build time using Ant. I'm familiar with how to do this with both weblogic and websphere but I cannot find any information on how to do this with the SAP j2ee engine. I know there is a way to have the server compile pages at startup but I want to be able to simply supply an ear with all of the compiled jsp's.

Thanks,

Chris
