Re: [jetty-users] Problems precompiling with Jasper2 in Jetty8

Hi Joakim,

I am a colleague of Wayne's helping him with his problem.  I've attached a simple ant build script and source to reproduce the problem we're having.  The build script is from your stackoverflow entry that Wayne linked to.  Note there is a circular dependency in that ant script as the "jspc" target depends on the "compile" target and compile is supposed to compile the servlet generated by the "jspc" target.  I'm no ant expert, but that doesn't seem to be related to the problem that Wayne is having.

Thanks and any help is much appreciated!

Thanks for the reply.


I don't have anything in the WEB-INF/lib directory. 


I do have both javax.servlet.jsp.jstl-1.2.0.v201105211821.jar and org.apache.taglibs.standard.glassfish-1.2.0.v201112081803.jar on the classpath.  This is correct, right?

Make sure you don't have any conflicting jars between what is in your WEB-INF/lib and what is in ${jetty.home}/lib/jsp


Keep in mind that Jetty itself, and even the maven plugin, isolates these differences for you with a webapp classloader.

But with ANT you have no such safety net, so you have to be extra careful to not have duplicate classes in both places.


A common scenario for that error is having 2 different (jstl) standard taglib jars.

I am migrating a webapp from Jetty6 (stop laughing, it's worked well for years) to Jetty8 and I'm getting the following error:

org.apache.jasper.JasperException: file:D:/dev/HEAD/eadev/clients/java/cfgmgr/jsp/displayAttribute.jsp(7,62) PWC6188: The absolute uri: cannot be resolved in either web.xml or the jar files deployed with this application

This compile use to work in Jetty 6 but now fails.  I see this in quite a few places in a Google search, but most appear in reference to this error when loading the webapp, not when precompiling it.

I tried changing the Ant task to follow joakime suggested task at but to no avail.

I am using 8.1.7.v20120910, but I get the same error with 7.6.7.v20120910.

The webapp is precompiled using an Ant task with the following target:
  <target name="jspc" depends="init, version_compile, mqservlets">

    <path id="jasper2.classpath">
      <fileset dir="${env.JETTY_HOME}">
            <include name="lib/servlet-api-*.jar" />
            <include name="lib/jsp/*.jar" />

    <pathconvert property="jasper2.classpath" refid="jasper2.classpath" />
    <echo message="jasper2.classpath=${jasper2.classpath}" />

    <mkdir dir="${webcfgmgr}/jsp/servlets"/>
    <taskdef classname="org.apache.jasper.JspC" name="jasper2" classpathref="jasper2.classpath"/>


The classpath output is:
     [echo] jasper2.classpath=D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\com.sun.el-2.2.0.v201108011116.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\javax.el-2.2.0.v201108011116.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\javax.servlet.jsp-2.2.0.v201112011158.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\javax.servlet.jsp.jstl-1.2.0.v201105211821.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\org.apache.jasper.glassfish-2.2.2.v201112011158.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\org.apache.taglibs.standard.glassfish-1.2.0.v201112081803.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\jsp\org.eclipse.jdt.core-3.7.1.jar;D:\dev\jetty-distribution-8.1.7.v20120910\lib\servlet-api-3.0.jar

The source line this barfs on is:
<%@ taglib prefix="c" uri="" %>

Anyone have any suggestions?  Thanks for any help you can give me.
