How to compile sources from an Ant script

I was given a script to compile sources and deploy them to Tomcat webserver.

If i compile the sources in Eclipse, they compile just fine.

But with the script I get the following output:

Buildfile: C:\Dev\workworkspace\myapp\build.xml
     [echo] website root dir is C:/Dev/ServerXamp/tomcat/myapp/myapp line sepa
rator is

clean-build:

compile:
    [mkdir] Created dir: C:\Dev\workworkspace\myapp\build\classes

This is because while compiling the CLASSPATH is incorrect. You can mitigate this by doing the following:

Add a property like this

<path id="compile.classpath">
    <fileset dir="WEB-INF/lib">
        <include name="*.jar" />
    </fileset>
</path>

Assuming that the libraries you need to compile the code lives under WEB-INF/lib ... if it resides somewhere else ... enter the path to that directory relative to your build.xml file

Now when compiling do the following:

<target name="compile" depends="copyfiles">
    <javac destdir="WEB-INF/classes" debug="true" srcdir="WEB-INF/src" includeantruntime="false">
        <classpath refid="compile.classpath" />
    </javac>
</target>

which is saying ... compile the java code in WEB-INF/src and put the class files in WEB-INF/classes ... and add the WEB-INF/lib (references by compile.classpath) to the CLASSPATH

you can use multiple tags to specify multiple classpaths
