Hessian4J Framework
Hessian is a replacement for XML when you need something fast and simple while direct access to the data (using a text editor) is less important. It is fast because it was designed that way, the Hessian format allows very fast parsers. It is simpler then XML, compact and complete implementations can be found for many languages.
Basically you can use it to stream any data to a file or over the network. Because Hessian is a very compact protocol most benefit will be gained in high load environments. In a RESTful environment you could use Hessian as the payload of your HTTP-POST request. Specifically for this purpose there is a separate draft proposal submitted to the IETF by Caucho. Examples where Hessian can be used:
- Persist data to a file.
- Use it to call a network service.
- Use it to post messages on an ESB.
A quick introduction to get started with the Hessian4J library can be downloaded here.
