52°North WPS Skeleton Project

You can use this project skeleton to develop WPS extension processes (algorithms), parsers for process inputs and generators of process outputs using Java.

More information is available at the 52°North Geoprocessing Community.

Adding a Java Algorithm to your WPS instance

There are two steps which you need to fulfill

1. Copy the resulting jar to (WPS-deployment-directory)/WEB-INF/lib
2. Add your new Algorithms to the WPS config (in (WPS-deployment-directory)/config/wps_config.xml)

The second step could look like:

...
<Repository name="LocalAlgorithmRepository"
	className="org.n52.wps.server.LocalAlgorithmRepository" active="true">
	<Property name="Algorithm" active="true">org.n52.wps.extension.ExtensionAlgorithm</Property>
	<Property name="Algorithm" active="true">org.n52.wps.extension.AnnotatedExtensionAlgorithm</Property>
	<Property name="Algorithm" active="true">org.n52.wps.server.algorithm.SimpleBufferAlgorithm</Property>
  ...
</Repository>
...

Only if you are using WPS 3.2.0 and later

If you add the fully qualified name of you algorithm to the file:

/META-INF/services/org.n52.wps.server.IAlgorithm

and drop the jar to (WPS-deployment-directory)/WEB-INF/lib, your algorithm will be added to the WPS automatically.
