Question

I am trying to make an ant script for an EJB project. I am using Jboss for this.
I am new to both EJB and Ant and am having problems in getting the beans to compile from ant. It gives me number of errors of the kind
package javax.persistence does not exist
@MappedSuperclass – Cannot find symbol

I created it as an eclipse project initially, and added the jboss runtime through eclipse. Do I need to copy all the jars in a lib folder and include them in the classpath for the beans to compile or is there a better way to do this?

Try setting classpath in Ant appropriately. It ignores any system CLASSPATH or Eclipse setting that you have.

Here’s an Ant build.xml that you can start with:

<?xml version="1.0" encoding="UTF-8"?>
<project name="spring-finance" basedir="." default="package">

    <property name="version" value="1.6"/>
    <property name="haltonfailure" value="no"/>

    <property name="production.lib" value="src/main/webapp/WEB-INF/lib"/>
    <property name="production.resources" value="src/main/resources"/>
    <property name="production.classes" value="${out}/production/${ant.project.name}"/>
