[ebxmlms-develop] Variable interpolation in configuration

[Jason v. Z. <ja...@ze...>]

Hi,

I've added variable interpolation in the XMLProperty.java file so that I
can more easily integrate Hermes into our application server. The
interpolation only works with system properties with the "ebxmlms"
prefix.

So I'm setting a system property in our application server with:

  <system-properties>
    <property name="ebxmlms.basedir" value="${plexus.work}/ebxmlms"/>
  </system-properties>

And then I can do something like the following in the
msh.properties.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Property>
  <MSH>
    <Log>
      <!-- "JDK" or "LOG4J" -->
      <UseLogger>LOG4J</UseLogger>
      <!-- empty path: user.home -->
      <LogPath>${ebxmlms.basedir}</LogPath>
      <LogFile>msh.log</LogFile>
      ...
    </Log>
  </MSH>
</Property>

This makes it very easy for integrators, like myself, to move the
application server around the filesystem and have things completely
self-contained.

So this means we can deploy Hermes and not have to deal with absolute
paths which is essential for our installation setup.

You can find the file here:

I'll send changes in whatever form you like. Do you prefer patches or
whole files?
