I.e. each service binding, during the activation phase, determines what its endpoint will be based on the various bits of information we discussed previously [1]. The domain doesn't actually run anything but just builds the model. Each node builds the runtime model of its composite separately as it has to link in with the local host environment. The domain doesn't provide the hosts that the nodes do. We could maybe come up with some pretend host that applies the url generation rules when the domain is building it's model based on which node is running the composite being processed but that's not what happens at the moment. 2. The endpoint information is changed by changes in the domain, for example, a wire is added or removed. If we can't find a reference binding and update it and we were to rely on the domain calculating all of the endpoints then each affected node would have to be restarted whenever such a change is made. The code that finds and updates binding information is coming together in updateComposite in nodeImpl(). It looks across all references and compares the bindings against the new composite being provided. As per the subject of this mail the hard part is working out which binding is which. Currently it only updates the binding URI which is not enough in some cases but I'm just trying this out at the moment. Simon [1] http://www.mail-archive.com/tuscany-dev@ws.apache.org/msg26102.html
Re: How to set a specific data binding to be used by a binding?

Re: [DAS] DAS as web service
Looks like you are starting to face some of the same issues I had in the past... I can see two issues here : Passing Data Graphs and Change Summary, and ensuring the client (e.g a web 2.0 application) would be SDO Enabled to handle this data representation and maintain it. Maybe a better alternative would be to leverage SCA to expose Data Service CRUD + Query interface utilizing SCA bindigns. We could leverage some of the work we have been doing on implementation.data for this and define a interface for SDO or for regular Pojos and use that interface as the main interface for the Data components.This would also give us some more flexibility in terms of what communication protocols would be supported (e.g ws, rmi, jsonrpc, etc) Well, these are only some initial thoughts, and I'd appreciate input from others on the community.

Re: I wish Tuscany would bind TM to JNDI

In this other post [1], it's mentioned a Hibernate scenario : For example, users who used much of Hibernate. Hibernate is easy to config to use XA Datasource from JNDI and TM as well. (But tuscany could not host any implementation of Hibernate). Does this mean users should have to abandon Hibernate? I'm sure this is not the initiation of Tuscany. If I understood correct what Mike proposed, this scenario is still valid, the difference is that, it would be responsibility of the runtime (based on some configuration) to properly retrieve the TM using JNDI or not, and would make it available to other Tuscany modules such as implementation types, etc. This is similar to what we do today with BPEL, except that we are not using JNDI (yet ?)

SCA is trying to move away from this kind of plumbing in the application to a model where the programmer simply asks for what is needed and it is up to the runtime to provide the facilities in whatever way it chooses. That is the intent/policySet model.

I guessed the above as you said you were flowing base64 encoded bytes,
and I didn't know what your WorkerManager interface looked like so
assumed it was like your WorkerService.
Or something else?
Hi,
I don't know how it's my WSDL, because it's automatically generated by
Tuscany Runtime whereas I use binding-sca-axis2 module, but the
WorkerService and the WorkerManager have different interfaces. By now
jobs are sent by my custom binding which uses xstream, so a lot of xml
serialization, but it's going to change due performance problems
inherent to xml. The WorkerManager has the task to control a group of
worker components in a node. So its business intefaces looks like that:
import org.apache.tuscany.sca.core.context.CallableReferenceImpl ;
import org.osoa.sca.annotations.Remotable;
@Remotable
public interface WorkerManager {
CallableReferenceImplWorkerService addWorker();
boolean removeWorker(String workerName);
boolean removeWorkers(int k);
boolean removeAllWorkers();
double getNodeLoad();
int activeWorkers();
void start();
}
You can add one or more components at runtime with the composite updater
ad then give away to the WorkpoolManager its CallableReference (i use
CallableReferenceImpl because my Tuscany runtime is not current patched
svn, but an old one). I'll show you a common use case:
Use case 1: The WorkpoolManager's polls different WorkerManagers in a
SCA domain, then it collects all nodes load with getNodeLoad(), if these
loads break some rule in the WorkpoolManager's engine. For example if
the system is run down, then the WorkpoolManager could add a new
worker by selecting a node, invoking its WorkerManager and adding a new
Worker Component at runtime on that node. After that, the
WorkpoolManager receives from that node's WorkerManager, a
CallableReference and it sends that reference to the WorkpoolService
which has the following interface:
@Remotable
public interface WorkpoolService {
@OneWay
void submit(Job i);
double getServiceTime();
@OneWay

}
In this case it uses a PostWorkerReference. In this interface you also
notice handleResult and PostWorkerName, this are my two hacks because i
wasn't able to inject dynamically a new component reference throught the
WorkpoolManager, so I use PostWorkerReference instead of the
PostWorkerName and handleResult instead of standard Tuscany Callbacks.
That's all hope it helps.
Cheers,
Giorgio.

Hi Giorgio. As you know I think we should get this checked in as an
sca/demo (is that the right place?). Are you happy that 1907 and 1863 are in
a suitable state to do that. We don't have to include it in the build
necessarily but it would be good if we can check out the code and look at
it.
It would be interesting (to me at least ;-) to see how the domain could
handle some of the issues of deploying the new components for you. I'm
wondering if you could split the function of the WorkManager in two
1/ A component that you use that to determine information about the load of
the node. In fact we could reuse the WorkManager component/service as part
of the set of node management services.
2/ When you need a new Worker component on a node use the domain services to
start a new composite there containing the component. The composite could be
created on the fly. We need two

Re: Policy Handlers ?
Hi, I've tried to add JAAS based 'authentication' to the security policies. I apologize for making this mail very long. Here is a overview of what I did... - JAAS depends on something called LoginModule and LoginConfiguration. I have assumed that this will be taken care of by the applications. - Our SCA runtime's role comes in where we perform the authentication function. The authentication must interface with the JAAS infrastructure and us the JAAS APIs such as the LoginContext.login(). I encapsulated this logic into a PolcyHandler which I have created in out policy-security. - I have then mapped this handler to a policyset name and this mapping is put in the services file of the java-runtime module - I then went up to the impl-policies sample, added a jaasAuthentication and jaasPolicySet to the definitions.xml. Then I specified 'jaasAuthentication' as a requirement for the AddServiceComponent's implementation. I am continuing to use the RuntimeWireProcessor to add the PolicyHandling Interceptor for handling polices along the invocation chain. Here are some observations... - The services file that maps policyhandlers to policysets must move out of the java-runtime and be defined in the individual policy domain modules.. such as policy-security or policy-transaction. Sebastien and Raymond has already suggested this. - The policyhanders need to be mapped to 'policy types' and not policysets. i.e. every policy handler has two things - 1) the policies (or policy structure) that it can make sense out of and 2) the QoS infrastructure with which it can interface. For now I could say that 'policytypes' are determined by the classnames that capture those policy models. But then, assume there is WS-Policy that we may be able to use for security and reliability and assume we have a policy handler that can deal with WS-Policy models, passing a WS-Policy object to the handler will not suffice. We also need to say if this the policy is for security or reliability. I hope that the policy handlers can decipher a bit of this by studying the model passed. - there seems to be a need to order the policy-handlers for their invocation and also make some conditions around their execution such as... should a hander continue to execute if the prev. one has failed and so on. In the sample I used, I had the logger and the jaasAuth policies and the logger handler continued to execute even when the authenticaion handler had failed. Maybe its fine for the logger since the failed ends up getting logged, but wonder if this would be ok if we had transaction along with authentication. - finally the user identity, in this just about the user name and password need to flow along. Right now I am using a callback handler that returns these to the JaasLoginModule. But in a real scenario I'd expect that the invocation chains bring along this information. Or alternatively the client dumps this sort of info somewhere and the server picks that up. Even there the client might have to pass some key to that info. I'll check this in after making changes to the policyhanlders services file.

The interceptor interacts with the transaction manager to make sure a global transaction is demarcated before the control hits the component implementation. The interceptor can be independent of the implementation types. In case 3 4, an transaction interceptor can be added to the invocation to suspend the current transaction before delegating to the next invoker and resume the transaction after the control is returned. In case 5, the binding.ws provider will have to deal with WS-AtomicTransaction to make sure the transaction context can be propagated over the SOAP protocol. In case 6, if there is an incoming transaction from the WS-AT, the binding.ws provider will need to import the transaction. It seems that the logic that enforces the intents could be a joint effort of a policy interceptor
Re: How to set a specific data binding to be used by a binding?
Hi, Are you trying to handle the case below? 1) The reference has a java interface and the source component calls a method such as String op(String str, int i); 2) And you try create a XML text as oparg0Str/arg0arg110/arg1/op and use it as the body for the JMSMessage. The JMS binding is special since it doesn't define the structure of the message for application data. The binding provider needs to decide the wire format. Let's assume we use the wrapper-style XML for now. If you want to have the databinding transformer to handle the wrapping, then you probably need to generate a WSDL from the java interface and use the WSDL as the binding interface contract. This way, the interceptor will take care of the data transformation and wrapping. The JMS binding code will receive the wrapper. Anthoer way you could do is to set the databinding to DOM or AXIOM. The databinding interceptor will pass you an array of elements corresponding to the java arguments. You can then create the wrapper from the child args when it reaches the JMS binding code.

Venkata Krishnan wrote: Hi, Heres what I am intending to do for the secure-bigbank into which I have copied over the exiting calculator, stockquote and account demos into secure-bigbank... - The Calculator and StockQuote services need to exchange data that cannot be tampered with since the AccountService heavily 'relies' on their results. So interaction with these two services should have 'integrity'. I don't think there is a need for authentication or confidentiality for the interactions with these services. - The AccountData service is right now accessed only by the AccountService. I'd like to open this out and put in the following security constraints :- - just keep authentication when accessed from the AccoutService locally say over binding.sca - enforce authentication, confidentiality and integrity when accessed from outside say over binding.ws - Finally the AccountService should enforce authentication, confidentiality and integrity. Does this sound ok ? After an iteration with interaction policies, I'll start working on some implementation policies. For example having 'authorization' enforced on the AccountDataService's operations. Thanks - Venkat I took a look at secure-bigbank. It's a good start which helps understand how to use the policy framework, and triggers some questions: - The accountDataService reference is bound to 8084, while the AccountDataService is bound to 8085? aren't they supposed to be wired together? - Why did you need two authentication and wsAuthentication intents? is it because you needed different policy sets on the client and service side? - Did you have to change the WS binding code to support your new user defined wsAuthentication intent? - Is there a way to not repeat the core intents defined by the spec in all contributions? - Where are the bindingType definitions listing the intents provided by the bindings? - What are the security callback handlers responsible for?

Just try to document the status of our incremental build plugin, there is one known issue to deal with pom projects (type=pom). 1) We need to find a way to detect if the pom.xml has been changed. There is no archive produced by this type of project. We may have to check if the pom in local maven repo is newer or not. 2) The maven invoker doesn't support non-recursive mode yet (mvn -N). As a result, we cannot simply run the mvn install command on the pom project. We can either request the maven invoker to support the non-recursive flag or we can try to call the maven installer directly.
