Ant build script for WebLogic Portal 10.3 projects

Question

Hi Friends,
I am going thru this document http://download.oracle.com/docs/cd/E12840_01/wlw/docs103/guide/ideuserguide/build/conUseCustomAntBuild.html#metadata about building ant script for my portal project. The document does not state few things clearly. Can you please help me to understand.
It says:
To Build an EAR File Using the Ant Script:
1. Generate the Ant script for each project in the EAR.
2. Generate the Ant script for the EAR project.
3. Configure the execution environment of your shell by executing wl.home/common/bin/commEnv.sh
4. Change to the Eclipse directory for the EAR project.
5. Execute the desired target in the EAR project's Ant script as follows:
ant build archive -Dworkspace=workspacepath
A) When I generate ant script, workshop generates build.xml file in each project directory and that includes EAR project as well. Then, point 2 is not clear, how do I generate another ant script (build.xml) for the EAR project?
B) I do not understand, "change to the eclipse directory for the EAR project". Does it mean, change to the directory of EAR project folder which has build.xml?
C) in step-5, execute the desired target, when I execute it, how it will know where are other build.xml files for other projects?

JT

Hi Greg,
I moved little bit but then got stuck with new kind of error.
a. First of all, my application has a 'data' project (.usr) file. When I try to generate ant scripts (build.xml), it says that 'data' project is not compatible with Workshop ant scripts. However, Workshop inbuilt EXPORT->EAR is able to build the projects without any error.
b. So, I thought, let's put a dummy build.xml file under 'data' project directory. This let ant build to proceed further. However, now it fails with error that <web project>/build.xml (line no. 122). Which is nothing but memory declaration (memoryMaximumSize="1024m"). The error says, 'unable to launch apt compiler', I am not able to understand what is it? The other projects' (ejb, controls etc.) build.xml has this declaration but they did not give this error, they built fine.
<web project>/build.xml
<target name="build" depends="init" description="compiles the source files; does not package the results">
<if>
<isreference refid="apt.factory.path"/>
<then>
<mkdir dir="${apt.src.output.dir}"/>
<for-each-java-src-path>
<if>
<available file="${.java.src.dir}"/>
<then>
<mkdir dir="${.java.src.output}"/>
<apt
sourcepath="${java.sourcepath}"
srcdir="${.java.src.dir}"
includes="${.java.src.include}"
excludes="${.java.src.exclude}"
destdir="${.java.src.output}"
preprocessdir="${apt.src.output.dir}"
classpathref="java.classpath"
factorypathref="apt.factory.path"
options="${apt.options}"
compile="false"
memoryMaximumSize="1024m"/>
</then>
</if>
</for-each-java-src-path>
</then>
</if>
Regards,
JT
