Re: javac cannot find package even though it is present in theclasspath

[John Colgrave <co...@hursley.ibm.com>]

This is how I compile code against j2ee.jar:

<target name="classes" depends="prepare">
    <javac srcdir="${src}/Java"
           destdir="${build}/classes">
        <classpath>
            <pathelement location="D:/j2sdkee1.2.1/lib/j2ee.jar"/>
        </classpath>
    </javac>
</target>

I prefer to have explicit control over the classpath rather than relying on the
system classpath.  I usually have other things (other pathelements or other
paths) in the classpath also but this is all that you need for j2ee.jar.
