AX2E is a brand new Java implementation of OASIS XACML 2.0 specification.

AX2E is going through a beta testing phase. You can take part in it, just send an e-mail to info@axescon.com. You'll get a beta tester license. If you agree with its terms, and reply with your acceptance e-mail, then you'll get URL to beta test package ZIP file.

We created a Google group for AX2E Beta Testers. You can join it too.

Hopefully, we'll be ready with final release by April 2006 or sooner.

Definitely, yes. Please, write an e-mail to info@axescon.com with a brief description of your needs and the project scope.

Yes. Obviously, we'd prefer to implement AX2E, but we can help with other vendor's products too. Please, write an e-mail to info@axescon.com with a brief description of your needs and the project scope.

AX2E stands for AXESCON XACML 2.0 Engine. We like this name because it also has a meaning of its own in stereochemistry. It's a formula for molecules of certain shape, for example SO₂. See, this page for more info.

JDK 1.4 and above.

• Apache Ant 1.6.x is required to compile and run samples. However, Ant can be replaced with any similar tool such as make or simple shell scripts.
• Java Mail API is required for RFC822Name attribute type support. We plan to remove this dependency in future
• Apache Xerce Java Parser.
• Apache XMLBeans project is optional, and used to manipulate XML files of XACML 2.0 Context and Policy schema documents. If XML representations of these objects are not used, then XMLBeans is not required.
• Saxon XQuery processor is optional and used for XPATH support in XACML 2.0.
• Spring Application Framework is optional, it can be used to configure AX2E components.

axescon.xacml.api.PolicyEvaluator interface represents PDP from XACML 2.0 specification. axescon.xacml.engine.PolicyEvaluatorImpl Java class is an implementation of this interface.

axescon.xacml.model.ctx.XacmlCtx class and axescon.xacml.api.CtxHandler interface represent the context and the context handler from XACML 2.0 specification. You, probably, have to write custom implementations, in order to accomodate particularities of your environment. For example, your context object may have LDAP attributes, and your context handler may have means to retrieve missing attributes from LDAP or database. However, AX2E has two context handler implementations ready for use: axescon.xacml.engine.BaseCtxHandler and axescon.xacml.test.conformance2_0.CTCtxHandler. XacmlCtx class implements the simplest form of XACML context, where all Request attributes are embedded in Request object. So BaseCtxHandler class retrieves attributes from the request object. Look at CTCtxHandler for an example of a little more sophisticated context handler, which returns values for certain attributes even when they are missing in the Request object. You can write your own context handler, which can connect to a database and fetch missing attributes from tables.

PEP (policy enforcement point) is out of the scope of AX2E implementation. PEP's role is to enforce authorization in the application. Chances are that your system already have some kind of PEP. You'll have to modify it, so that it will use AX2E to make authorization decisions.
