Get the [latest executable jar from Maven Central](http://central.maven.org/maven2/org/ow2/authzforce/authzforce-ce-core-pdp-cli/) with groupId/artifactId = `org.ow2.authzforce`/`authzforce-ce-core-pdp-cli` and make sure you are allowed to run it (it is a fully executable JAR), e.g. with command:
```
$ chmod a+x authzforce-ce-core-pdp-cli-16.0.0.jar
$ chmod a+x authzforce-ce-core-pdp-cli-14.0.0.jar
```
To give you an example on how to test a XACML Policy (or PolicySet) and Request, you may copy the content of [that folder](pdp-cli/src/test/resources/conformance/xacml-3.0-core/mandatory) to the same directory as the executable, and run the executable as follows:
*`pdp.xml`: PDP configuration file, that defines the location(s) of XACML policy(ies), among other PDP engine parameters; the content of this file is a XML document compliant with the PDP configuration [XML schema](pdp-engine/src/main/resources/pdp.xsd), so you can read the documentation of every configuration parameter in that schema file; **Feel free to change the policy location to point to your own for testing.**
