Tuscany allows you to publish Web resources using SCA components declared with an <implementation.resource> component implementation type and made available to HTTP clients using a <binding.http> binding.
Here is the SCA composite that publishes this page:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
targetNamespace="http://web"
name="WebResource">
<component name="myWeb">
<implementation.resource location="myContent"/>
<service name="Resource">
<binding.http/>
</service>
</component>
</composite>
