Subject Re: Precompiling JSPs
Date Thu, 19 Jun 2003 11:19:16 GMT
Here's my problem with JspC task:

"does not factor in class or taglib dependencies, or <jsp:include>
references. "

Quote from the page mentioned below!!

I need these things factored in or else you cannot run javac on these *.java
files.

Thanks,

Andoni.
