Re: [Xdoclet-user] ReplaceCopy task fails

[Erik Hatcher]

I've never used ReplaceCopy, so can't help with this particular 
problem, but I recommend having a look at VPP <http://vpp.sf.net> and 
perhaps using it instead.  The VPPFilter is pretty darn slick!

I'm using the ReplaceCopy task defined as:

    <taskdef
      classpathref="class.path"
      name="replacecopy"
      classname="xdoclet.ant.ReplaceCopy"
      />
where the class.path ref contains all the jar files within the xdoclet
1.2 lib dir as well as j2ee.jar (j2sdkee) and tools.jar (j2sdk).
One of the targets is (it's used in lot's of places - this is just the
simplest):
  <target name="appxml" depends="init">
    <replacecopy
      file="${meta.path}/application.xml"
      todir="${build.meta.path}"
      />
  </target>
Where application.xml contains:

<!DOCTYPE application
  PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN"
  "http://java.sun.com/dtd/application_1_3.dtd";>
<application>
  <display-name><XDtAnt:property 
name="app.display.name"/></display-name>
  <description><XDtAnt:property name="app.description"/></description>
  <module>
    <ejb><XDtAnt:property name="project.name"/>.jar</ejb>
  </module>

  <module>
    <java><XDtAnt:property name="project.name"/>.util.jar</java>
  </module>
  <module>
    <web>
      <web-uri><XDtAnt:property name="project.name"/>.war</web-uri>
      <context-root><XDtAnt:property 
name="project.name"/></context-root>
    </web>
  </module>
</application>

With the 1.2b2 xdoclet and ant 1.5.3-1 it worked fine. When I upgraded
to xdoclet release 1.2 it started giving NullPointerException:
appxml:

Any hints what I'm doing wrong?
