How do I include a jar file into a lib folder of an ear file using ant?

Question

I have the following folder structure:

project.ear
        lib folder
            ProjectEJBClient.jar
        META-INF folder
        projectEJB.jar

My build.xml contains the following lines to create EAR package

<ear destfile="${build.dir}/myapp.ear" appxml="${src.dir}/metadata/application.xml">
      <fileset dir="${build.dir}" includes="ProjectEJBClient.jar"/>
      <fileset dir="${build.dir}" includes="projectEJB.jar"/>
</ear>

The above code can't create an EAR package with lib folder which includes the ProjectEJBClient.jar file

I want to create a lib folder and copy ProjectEJBClient.jar into that lib folder.

After this process I want to make an EAR project with this lib folder.

I don't know how to create lib folder and copy ProjectEJBClient.jar into that folder and include this folder into project.ear.

Answer 1

Use a zipfileset:

  <ear destfile="${build.dir}/myapp.ear" appxml="${src.dir}/metadata/application.xml">
    <zipfileset dir="." prefix="lib">
      <include name="ProjectEJBClient.jar"/>
    </zipfileset>
    <fileset dir="${build.dir}" includes="projectEJB.jar"/>
  </ear>

The prefix="lib" will make sure, that the jar will be under /lib in your ear.
