Package org.apache.jasper

Class JspC

  • All Implemented Interfaces:
    java.lang.Cloneable, Options
    public class JspC
extends org.apache.tools.ant.Task
implements Options
    Shell for the jspc compiler. Handles all options associated with the command line and creates compilation contexts which it then compiles according to the specified options. This version can process files from a _single_ webapp at once, i.e. a single docbase can be specified. It can be used as an Ant task using: 
       <taskdef classname="org.apache.jasper.JspC" name="jasper" >
      <classpath>
          <pathelement location="${java.home}/../lib/tools.jar"/>
          <fileset dir="${ENV.CATALINA_HOME}/lib">
              <include name="*.jar"/>
          </fileset>
          <path refid="myjars"/>
       </classpath>
  </taskdef>
