      org.apache.shale.faces.ShaleVariableResolver

public class ShaleVariableResolver
extends javax.faces.el.VariableResolver

Shale-specific VariableResolver for evaluating JavaServer Faces value binding and method binding expressions. The following special variable names are recognized, and evaluated as indicated:

• jndi - Returns the JNDI context at name java:comp/env (relative to the initial context supplied by the container.

All other evaluations are delegated to the previous implementation that was passed to our constructor.

Since 1.0.1, if the optional shale-tiger.jar file (containing the Shale Tiger Extensions) is available to this web application, the extra variable resolver implementation found there will be interposed between this instance and the previous implementation instance passed to our constructor.
