The complex plug-in sample in the samples\correlator_plugin\java directory of your Apama installation is comparable to the corresponding C and C++ complex plug-in samples.

The Java code for the ComplexPlugin class contains the public static methods: test1, test2, test3, and test4. It also contains an object, ComplexChunk that represents a complex type.

The complex_plugin.xml file is the plug-in's deployment descriptor and contains the <plugin> stanza that specifies the name, class, and description for the plug-in.

The sample's ComplexPlugin.mon file contains the EPL code for the Apama application. It imports the plug-in and calls the various testx methods.
