SCA WCF Integration
I have a question regarding WCF and SCA integration which I am hoping someone in this list can give clarity to. As far as I see it currently a WCF Web service is not part of the SCADomain. If a composed component had a dependency on a WCF component could an explicit reference be set to that WCF web service in the SCDL file? Or is this an internal matter and how we connect and invoke the WCF component should be encapsulated in our SCA component?

Re: SCA WCF Integration
You are correct that in Tuscany currently we don't have any way to make a WCF Web service part of the SCA domain. I think there are (at least) two options for how you could do this. 1. Use binding.ws on a SCDL reference to connect from the SCA domain to the WCF Web service. The reference is part of the SCA domain but the WCF Web service that it invokes is not part of the SCA domain. 2. Create an SCA service that encapsulates the WCF service, and wire to this SCA service in the usual way. The encapsulating SCA service is part of the SCA domain. It would be possible to create a new component implementation type implementation.wcf to specify this encapsulation and perform the necessary WCF invocations. This is a great topic to discuss and I'm sure others will have other alternatives and opinions on the pros and cons of various approaches.

RE: SCA WCF Integration
Our client is also very interested in this topic, be very interested in seeing how it performed tighter integration, such as being able to declare an intent on a wcf service method and use the Tuscany or other SCA policy framework to satisfy the intent at runtime. Just one of many examples, I don't know a lot about W.CF but it does seem that the approach is very similar to SCA, so in theory, a binding shouldn't necessarily be Uber difficult. Is anybody else interested in tighter integration up there?

Please nominate the bug fixes for Tuscany SCA Java 1.0.1 release
Hi, As it was originally proposed, we'll do a SCA Java 1.0.1 release using the 1.0 branch as the base line. The 1.0.1 is intended to be a bug fix release and it should contain only non-disruptive changes. The approach we take is to pull post-1.0 commits of incremental bug fixes from the trunk and merge them into the 1.0.1 branch. Please start to nominate what fixes should be pulled into this release as soon as you can. I created a wiki page at http://cwiki.apache.org/confluence/display/TUSCANYWIKI/Desired+bug+fixes+for+SCA+Java+1.0.1+release. I would appreciate if you can fill in your desired items there. We probably need to coordinate the merges once we have the list built by the community. Thanks, Raymond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi Susanta, you mentioned I'm writing a meshup sample using SCA. Here I'm using one composite written in Ruby which requires rubygem. would you like to contribute your sample to Tuscany?

Re: Interceptors between services
Hi,
You need to add an extension to Tuscany and then you can add interceptors as
follows:
1) Implement the org.apache.tuscany.sca.invocation.Interceptor interface for
your interceptor
2) Implement org.apache.tuscany.sca.runtime.RuntimeWireProcessor interface
public void process(RuntimeWire wire) {
ListInvocationChain chains = wire.getInvocationChains();
for (InvocationChain chain : chains) {
chain.addInterceptor(...); // Add your interceptor here per
operation
}
}
3) Implement org.apache.tuscany.sca.core.ModuleActivator interface and
register your impl class with
org.apache.tuscany.sca.runtime.RuntimeWireProcessorExtensionPoint in the
module activator.
public class YourModuleActivator implements ModuleActivator {
public void start(ExtensionPointRegistry registry) {
RuntimeWireProcessorExtensionPoint wireProcessorExtensionPoint =
registry.getExtensionPoint(RuntimeWireProcessorExtensionPoint.class);
if (wireProcessorExtensionPoint != null) {
wireProcessorExtensionPoint.addWireProcessor(new
YourRuntimeWireProcessor(mediator, dataBindings));
}
}
public void stop(ExtensionPointRegistry registry) {
}
}
4) Register your module activator in a file named
META-INF/services/org.apache.tuscany.sca.core.ModuleActivator. The content
of the file will be the implementation class of your module activator.
The steps are a bit involved. We could simplify the RuntimeWireProcessor
extensions by allowing registration using
META-INF/services/org.apache.tuscany.sca.runtime.RuntimeWireProcessor.
This will be a TODO for our future releases.
Thanks,
Raymond

Re: Handling authentication for non-web services?
Hi Jason, Here are some thoughts for your queries on the policies and enabling authentication to leverage from an LDAP registry. - Our Axis2 based WS Binding uses the Apache Rampart module for enabling security around the web services hosted by our SCA Runtime. If you look at the sample helloworld-ws-service-secure and helloworld-ws-reference-secure it uses simple user id and password based authentication. There is a password call back handler in the sample that actually deals with looking up a userId and password and verifying if it matches. This handler is probably the place from where you might need to connect to your LDAP registry to authenticate. I am not aware of Rampart handlers that can directly go over to a specified LDAP registry and do this check, hence avoiding the code you may now have to write in the handler. On your other issue with sockets, it seems to me that you are wanting to do that for supporting rich clients. Though I am not sure if it would fit your requirement maybe you could take a look at our binding-dwr (binding based on direct web remoting) and the chat sample that uses this. - Venkat On 10/20/07, Jason Clark [EMAIL PROTECTED] wrote: -Jason # This electronic mail transmission contains confidential information intended only for the person(s) named.

On 10/19/07, Jason Clark [EMAIL PROTECTED] wrote: That's a lot of text to scroll through, so I'll just add my comments at the top. In regards to how the service is selected, this is based on information within the message. Authentication simply determines if the message is allowed to pass on. In regards to the protocol between tomcat and the service, once authentication is accepted, the message is simply forwarded to the service. The service itself handles the entire message parsing. There seem to be some alternatives here then. Convert the current services to SCA Components and maintain the servlet routing component. This would be my first suggestion to get you up and running and give you a feel for what Tuscany can do. The servlet of course needs to talk to the services. This can be done either locally or remotely using a binding of your choice. So the servlet would need to be modified to hold references to services in the SCA domain. You can see examples of Tuscany running in a web app, for example, calculator-webapp. These webapp samples don't run as part of the distributed domain yet but I'm looking at that at the moment. I don't want to give the impression that I think everything must live inside of SCA but just thinking aloud about some other things that could be done... Based on what you have said already I'm assuming that you can't change your clients and that they currently provide the XML message as part of an HTTP POST. Construct a gateway component (in place of the servlet) that accepts the XML over an HTTP binding. The function of the component would be to route the message to wired components based on the contents of the XML. To make this work we'd have to fix up binding.http to accept POSTed data. On the OSOA page, there is a section on bindings that covers ws and jms, but I have been unable to find documentation on the http, rss, and atom bindings. Is there any documentation that outlines the schema for the various bindings available? I've seen discussions recently about hosting web applications in SCA as well as the other way round. So in the future the solution maybe that you just take the servlet you have and deploy that as a component. There's no support yet though. Construct a set of policies to handle the LDAP based authentication activity for binding.http . I've seen the WS policies sample, but I'm still trying to figure the policies system out. If it's not a bother, can you give me a quick example on how I would deal with LDAP based authentication for the http binding given that user name and pw have been passed in the message? If you can change your clients then there are of bindings that could be used while keeping the same XML message structure. The service interface extends our own general MessageService interface which has methods for receiving text messages it will have to parse as well as a
