JSFSpy can be extended using WARlets. A WARlet is a WAR plug-in that adds UI and code to a Servlet 3/JSF 2 application.
To extend JSFSpy with WARlets you will need:
- The WARlet container jar.
- One or more WARlets, each packaged in its own jar.
To install WARlet functionality, just put the WARlet container jar into WEB-INF/lib along with the JSFSpy jar.
There is currently one WARlet available called EL_Evaluator. This provides an interactive UI that evaluates an EL expression against your application. If you add the EL_Evaluator jar to WEB-INF/lib then a new button will appear in JSFSpy that launches the EL_Evaluator WARlet and makes it part of the JSFSpy applicatioin.
