Ant script to load and compile .java files

Hi,

I have a File uploading utility that loads WTDocuments to Windchill.

I want to load this package onto Windchill and compile it using ant script.

So far, I have managed to copy the package (which is a bunch of .java files) onto the src folder using the following ant script:

<target name="taskUnzip">
          <unzip src="${packagestructure}/myuploadutility.zip" dest="${wc_src}"/>
</target>

I use the following task to compile it:

<target name="compile">
  <javac srcdir="${wc_src}" destdir="${wc_codebase}"/>
  </target>

But this throws several errors similar to :

\myuploadutility.java:5: error: cannot find symbol

    [javac] import com.ptc.netmarkets.model.NmOid;

    [javac]                                ^

    [javac]   symbol:   class NmOid

    [javac]   location: package com.ptc.netmarkets.model

So I think I am writing the tasks the wrong way. So, how to load the package, compile it, so that the .class files get stored in codebase?

Please help.

Thanks in advance.

Note: I know it's possible to make a jar file of all the .class files directly and put them into codebase. However, requirement specifies a .zip file containing .java files only.
