## org.apache.jasper
Class JspC

    java.lang.Object
      org.apache.jasper.JspC

All Implemented Interfaces:
  Options

public class JspC
extends java.lang.Object
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 a Ant task using:

         <taskdef classname="org.apache.jasper.JspC" name="jasper2" >
            <classpath>
                <pathelement location="${java.home}/../lib/tools.jar"/>
                <fileset dir="${ENV.CATALINA_HOME}/server/lib">
                    <include name="*.jar"/>
                </fileset>
                <fileset dir="${ENV.CATALINA_HOME}/common/lib">
                    <include name="*.jar"/>
                </fileset>
                <path refid="myjars"/>
             </classpath>
        </taskdef>

        <jasper2 verbose="0"
                 package="my.package"
                 uriroot="${webapps.dir}/${webapp.name}"
                 webXmlFragment="${build.dir}/generated_web.xml"
                 outputDir="${webapp.dir}/${webapp.name}/WEB-INF/src/my/package" />
