Download the latest "cweb-xpointer" release from SourceForge. This project uses Apache Maven and Java 1.4+, so you will need to install those as well. Normally you will also want to download one of the XPointer Framework integrations, such as the xpointer+dom4j or the xpointer+jdom package. These "integration packages" provide support for a specific XML Document model. The project dependencies are explicitly declared in the Maven POM. This means that Maven can automagically download the required releases of dependent JARs. There are several release artifacts. The "uberjar" release provides an executable command line utility and bundles all dependancies. If you want to integrate into an existing application, then you should use the cweb-xpointer JAR and also download copies of its dependencies. If you are using a Maven project, then this is all very, very easy.
