Good Evening Joseph-
what is the specific error you are getting?
which version of which AppServer are you deploying to?
if you are using EJB 2 (the default) we will need to see ejb-jar.xml Any or all
Java Sources (just attach every java source file that extends EJBHome) how are
you building the ear (assume either build.xml or pom.xml?) GlassFish has a ear
builder and deployer in $GLASSFISH_HOME/GlassFish/Sun/AppServer/common-ant.xml
that looks something like this:
<property name="jarDD" value="ejb-jar.xml,sun-ejb-jar.xml"/>
<!-- ======================================================= -->
<!-- Assemble EJB JAR module. OLD WAY -->
<!-- ======================================================= -->
<target name="create_ejbjar_common_old" depends="clean_ejbjar_common">
<mkdir dir="${assemble.ejbjar}"/>
<jar destfile="${assemble.ejbjar}/${ejbjar}">
<zipfileset dir="${build.classesdir}/${jar.pkg}/" includes="**/*.class"
excludes="**/servlet/, **/client/" prefix="${jar.pkg}"/>
<metainf dir="${jarDD.dir}" includes="${jarDD}"/>
</jar>
<!-- AEM NEEDED?copy file="${assemble.ejbjar}/${ejbjar}"

<property name="ejbjar.done" value="true"/>
</target>
<!-- ======================================================= -->
<!-- Assemble CLIENT JAR module. OLD WAY -->

<target name="clientjar_common" depends="clean_clientjar_common">
