When creating the Publication, one of the parameters required is the context. Right now, this is hard coded. I have yet to figure out a way to get this. Obviously, hard coding is not the solution - still working on this. Thinking about putting the context in a properties files somewhere. Most of this code was taken from the action `org.apache.lenya.cms.cocoon.acting.UploadAction.java` and modified to work with Fred. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
