public class JspC
extends MatchingTask

Runs a JSP compiler.

This task takes the given jsp files and compiles them into java files. It is then up to the user to compile the java files into classes.

The task requires the srcdir and destdir attributes to be set. This Task is a MatchingTask, so the files to be compiled can be specified using includes/excludes attributes or nested include/exclude elements. Optional attributes are verbose (set the verbosity level passed to jasper), package (name of the destination package for generated java classes and classpath (the classpath to use when running the jsp compiler).

This task supports the nested elements classpath (a Path) and classpathref (a Reference) which can be used in preference to the attribute classpath, if the jsp compiler is not already in the ant classpath.

Usage

 <jspc srcdir="${basedir}/src/war"
       destdir="${basedir}/gensrc"
       package="com.i3sp.jsp"
       verbose="9">
   <include name="**\/*.jsp" />
 </jspc>
