error while precompiling JSP with ant file

[bouml]

Hi !
 
I want to precompile my JSP files with a ant file.
 
after starting the ant file i get this error:
 
java.lang.NoClassDefFoundError: org/apache/jasper/jspc
Exception in Thread "main".
 
I'm working with tomcat 3.3. 
I searched in all jar files but didnt find anything. 
After searching in all jat files of a tomcat 4.x i found
"jasper-compiler.jar" , which I also add to my clsspath.
but i have still the same error.
 
What did i do wrong ?
 
thanks.
