Overview:
---------
The Imperius binding for Java (JavaSPL) processor currently operates in 
an embedded mode only. Which means you need to write the wrapper code 
that interacts with the processor.
JavaSPL ships with a sample wrapper under 
org/apache/imperius/samples/simplepolicies/RunSamples.java 

The runsamples script simple invokes this wrapper.

The /policies folder contains some simple JavaSPL policies that showcase
the various features of the language.


Prerequisites:
--------------
1. ANTLR 2.7.7 : Can be downloaded from http://www.antlr2.org. Make sure to set 
		 the ANTLR_HOME environment variable
2. JDK 142 : The java executable must be on the PATH

Running the Samples:
--------------------

Open a command prompt and execute the runsamples script

This script will execute all the policies one by one. It will first try to delete
the policy, then create it and finally run it.
Note: If the policy does not exist an exception will be thrown ignore the exception

To run a single policy invoke the script as follows:

runsamples <policyname>


The Policies:
--------------

1. Basic Policy: 

A simple policy that demonstrates:

-Importing multiple classes with multiple instances.
-Invoking methods of imported instances
-Returning values as part of decision

2. MacroSample:

-Demonstrates how to define and use a Macro within a policy

3. MultiplePolicySample:

-Demonstrates how to define multiple sub-policies

4. ComplexPolicy:

-Demonstrates the use of several built-in operators including
String, Numeric, DateTime and Collection

5. DateTime

-Demonstrates several datetime operators

6. InvokeMethodSample

-Demonstrates how to invoke a method on the imported instance
as part of the decision

7. SimplePolicy

-A very simple poliy
