[Laszlo-dev] Packaging/deploying OpenLaszlo apps, generating the LPS folder for the app?

[Raju Bitter]

And based on the build.xml, the classpath I'm using.

  <!-- CLASSPATH for Laszlo compiler lzc -->
  <path id="laszlo.compiler.classpath">
    <pathelement location="${LPS_HOME}/WEB-INF/lps/server/build"/>
    <pathelement location="${LPS_HOME}/WEB-INF/classes"/>
    <pathelement location="${servlet.jar}"/>
    <fileset dir="${LPS_HOME}/WEB-INF/lib" includes="**/*.jar"/>
  </path>

I attached a ZIP file generated by this build file. But you can take
any LZX file, run "ant all" and you can see the effect as well.
$LPS_HOME must be set, and have to set the properties in the
build.properties accordingly.

Thanks,
Raju
