FraSCAti Velocity for Light Proxy

[JGuillemotte]

Evaluate FraSCAti Velocity for light proxy.

Modify the ligth proxy to use FraSCAti Velocity, to do during the refactoring of esper-frascati-poc project.

Goal is to make a dynamic WSDL to HTML transformation proxy by using a XSLT transformation file.

Evaluation is OK.

I have made an example using FraSCAti Velocity. In the composite file, need to add this block : `

<service name="Velocity">
  <binding.http xmlns="http://tuscany.apache.org/xmlns/sca/1.0" uri="/pages"/>
</service>

`

Result is to publish on localhost:8090 the page index.html that contains directly the velocity code. Request parameters are accessed simply as a standard VTL variable. By adding a reference tag in the Velocity component, we have acces in the index.html page to the reference implementation.

Also wrote unit test of velocity-scripted call using a dynamically generated form (from the wsdl) : org.openwide.easysoa.test.FormGeneratorTester .

What will be addressed from now on :

• 59 Scaling up FraSCAti proxies, including making proxy call proxied services in a more FraSCAti-like way (outgoing binding.http)

• Further scaffolding features, such a handling complex service types, including prospective FraSCAti and Nuxeo features : see #58 EasySOA Light - Further scaffolding features

Velocity more fully used in new, object-model based scaffoldingProxy, see https://github.com/easysoa/EasySOA/issues/43
