> The [Oozie 2.3 documentation|http://yahoo.github.com/oozie/releases/2.3.0/WorkflowFunctionalSpec.html#a3.2.7_Java_Action] has this to say about capturing the output of a Java action:
> {quote}
> The capture-output element can be used to propagate values back into Oozie context, which can then be accessed via EL-functions. This needs to be written out as a java properties format file. The filename is obtained via a System property specified by the constant JavaMainMapper.OOZIE_JAVA_MAIN_CAPTURE_OUTPUT_FILE
> {quote}
> That last sentence is wrong for the latest releases. The Java action should write out the properties to a file whose name is given by the system property {{oozie.action.output.properties}}. These properties can then be accessed in a subsequent action using an EL expression like ${wf:actionData('foo')['bar']}, where {{foo}} is the name of the Java action and {{bar}} is the key for the desired property.
