What Tuscany Object do you have as the starting point? If you bootstrap Tuscany using SCANodeFactory, you can look into http://svn.apache.org/repos/asf/tuscany/branches/sca-java-1.5.1/modules/node-impl/src/main/java/org/apache/tuscany/sca/node/impl/NodeImpl.java.
There are two methods related: getServiceReference() getComposite() If you use Tuscany web application, take a look at http://svn.apache.org/repos/asf/tuscany/branches/sca-java-1.5.1/modules/host-webapp/src/main/java/org/apache/tuscany/sca/host/webapp/WebAppServletHost.java. There is an attribute set into the ServeletContext for the SCADomain object.

What I want to do is that use a servlet or jsp to automatically list all components in that composite and then allow user to invoke some service through web. I don't know what is the best way to do it? I checked all the class provided, just cannot find some classes serving this kind of functions. please help.

If you are using 2.x, how do you bootstrap Tuscany? Are you using NodeFactory.newInstance().createNode(...)? org.apache.tuscany.sca.node.impl.NodeImpl.getDomainComposite() can give you the information. But this method is not available on org.apache.tuscany.sca.node.Node interface. Node.getService() or org.oasisopen.sca.client.SCAClient.getService() allows you to get service proxies using <componentName>/<serviceName>, but you cannot list all the services. If you can give us more details about your scenario, we can probably work out a solution without hacking the current code.

I checked some doc, it seems CurrentCompositeContect class should serve this function. but it seems not exist any more. Do you know what java classes I can use for this purpose? Many Thanks , Malujo
