The following topic explains how to create an Ant task that calls the command line tool wlwBuild.cmd. wlwBuild.cmd is used to create application-level EAR files or project-level JAR files for deployment to a production server.
To create an Ant build.xml file, you can either auto-generate a build.xml file or you can write the file by hand.
To auto-generate an Ant build.xml file for the application
Open the target application in WebLogic Workshop.
The generated Ant file contains two tasks by default: "build" and "clean". When calling the build file from the command line, use the -f flag to name the file exported_build.xml:
C:\bea\weblogic81\samples\workshop\SamplesApp>ant -f exported_build.xml build
To build selected projects with the application, modify the <build> element within the exported_build.xml file. By adding the attribute project="Schemas", only the Schemas project will be build:
<target name="build"> <!-- Builds the full application creating an ear at the specified location. The server classpath parameter is used, but may be omitted if the server home directory configured in Workshop is accessible. --> <wlwBuild work="${app.dir}/${work.file}" serverclasspath="${server.classpath}"> <build outputdir="${output.dir}" outputfilename="${output.file}" project="Schemas"/> </wlwBuild> </target>
See the documentation within the exported_build.xml file for more information about specifying output directories, output file names, etc.
You can also export an Ant build.xml file for building an individual project in much the same way as you do for the application.
To auto-generate an Ant build.xml file for a project
Open the target application in WebLogic Workshop.
You can call the wlwBuild.cmd command line tool from an Ant script by using the <EXEC> task. For more information see the the Apache Ant 1.5.4 Manual and the reference documentation for the wlwBuild Command.
