Using Jikes instead of JavaC with Tomcat/Jasper

[Yair Zadik <ya...@disappearing.com>]

I've been trying to get Tomcat to use Jikes instead of javac
as its Java compiler for JSP pages.  All the information I've
found says to edit the conf/web.xml file.  As far as I could
tell, this did nothing, so I poked around the sources.
According to 'WebXmlReader.java' (in 3.2.1):

	    // We may read a "default" web.xml from INSTALL/conf/web.xml -
	    // the code is commented out right now because we want to
	    // consolidate the config in server.xml ( or API calls ),
	    // we may put it back for 3.2 if needed.
	    // note that web.xml have to be cleaned up - only diff from
	    // default should be inside
	    // readDefaultWebXml( ctx );

so it appears that conf/web.xml is no longer read.  However,
adding 

  <servlet>
    <servlet-name>
      jsp
    </servlet-name>
    <servlet-class>
      org.apache.jasper.servlet.JspServlet
    </servlet-class>
    <init-param>
            <param-name>jspCompilerPlugin</param-name>
            <param-value>org.apache.jasper.orgpiler.JikesJavaCompiler</param-value>
    </init-param>
    <load-on-startup>
        -2147483646
    </load-on-startup>
  </servlet>

  <servlet-mapping>
      <servlet-name>
            jsp
      </servlet-name>
      <url-pattern>
            *.jsp
      </url-pattern>
  </servlet-mapping>

(basically, the jsp servlet definition and mapping from conf/web.xml) into
my webapp's 'web.xml' file seems to do the trick.

Is there a way of doing this now without altering my webapp?  I'd like to
make this mapping the default rather then the standard JavaC mapping.  Does
this require writing a WebXmlReader replacement?
