Not able to build osb jar using osb 10.3

Question

Hi All,
I am working on developing an osb jar from workspace(osb 10.3) using ant scripts.When i am trying to invoke an ant with target "export" it show an error "Java returned :13".I went through the entire post sent by respected people over the forum but i am not able to solve it.
Script which i am using :
<project name="ConfigExport">
<property file="./build.properties"/>
<property name="eclipse.home"
value="${bea.home}/tools/eclipse_pkgs/2.0/eclipse_3.3.2/eclipse"/>
<property name="weblogic.home" value= "${bea.home}/wlserver_10.3"/>
<property name="metadata.dir" value="${workspace.dir}/.metadata"/>
<target name="export">
<available file="${metadata.dir}" type="dir"
property="metadata.dir.exists"/>
<java dir="${eclipse.home}"
jar="${eclipse.home}/plugins/org.eclipse.equinox.launcher_1.0.1.R33x_v20080118.jar"
fork="true"
failonerror="true"
maxmemory="768m">
<arg line="-data ${workspace.dir}"/>
<arg line="-application com.bea.alsb.core.ConfigExport"/>
<arg line="-configProject ${config.project}"/>
<arg line="-configJar ${config.jar}"/>
<sysproperty key="weblogic.home" value="${weblogic.home}"/>
</java>
          <antcall target="deleteMetadata"/>
</target>
     <target name="deleteMetadata" unless="metadata.dir.exists">
<delete failonerror="false" includeemptydirs="true"
dir="${metadata.dir}"/>
     </target>
</project>
It seems that on debugging the error in eclipse log say for ex: C:\bea\tools\eclipse_pkgs\2.0\eclipse_3.3.2\eclipse\configuration\
show me an error saying : "java.lang.RuntimeException: Application "com.bea.alsb.core.ConfigExport" could not be found in the registry."
It seems that com.bea.alsb.core.ConfigExport not able to find the class which is used to export an osb jar.Moreover in the thread posted basically talks about osb 11 so i am not able to find many folders like middleware,oracle,osb.home.
Please let me know what is the possible solutions for this in osb 10.3.

Answer 1

see here Export from OEPE not working for an answer, that I copy/paste here:
You have to verify if your OEPE instalation has the following file in the directory dropins (e.g C:\Oracle\middleware\oepe11.1.1.3\dropins)
filename:
oracle.osb.ide.link
content:
path=C:/Oracle/Middleware/Oracle_OSB1
Under the Oracle_OSB1 you have an eclipse directory with needed plugins:
e.g. C:/Oracle/Middleware/Oracle_OSB1/eclipse is not empty
This is only a sample directory naming from Windows installation, I had a problem on RHEL 5.3 where installer did not put such files.
Then I took the files from Windows installation.
I suspect the files are installed "automatically" but I am not sure when.
