    <p>Your use case is actually very hard to implement with JAX-WS (and maybe even impossible). But do not worry, you are not the first one with this requirement.</p> <p>Imagine a big company with several legacy systems that need to be integrated. Then they spent a lot of money and time implementing an SOA architecture based on SOAP web services. These services are combined (orchestred) to create business process.</p> <p><strong>Example:</strong> The business process 'Create a contract' needs the execution of the web services A, B and C. </p> <p>But what happen if changing the business process needs some code source changes??? The company needs to have a development team keeping those process up-to-day.</p> <p>To solve this, <strong>BPEL's dynamic binding</strong> was created. This technology allows you to compose a new service at runtime based on the parameters of the requested service! </p> <p>In a few words, what you need to do if define several 'base web services' and then configure a BPEL server to dynamically combined those services at runtime!</p> <p>Please read <a href="http://www.oracle.com/technetwork/articles/carey-090553.html" rel="nofollow">this article</a> from Oracle to get an idea ...</p> <p>And check here the <a href="http://docs.redhat.com/docs/en-US/JBoss_Developer_Studio/4.0/html-single/JBoss_BPEL_User_Guide/index.html" rel="nofollow">JBoss BPEL user guide</a>.</p> <p><strong>What you should do to use BPEL in your case</strong></p> <ul> <li>Create SOAP a web service for each of your non-soap services (lets call this 'base webservices').</li> <li>Configure a BPEL engine to orchestrate the composition/combination of the 'base web services'.</li> <li>Create clients capable to composes/combines the 'base web services' at runtime (per each request if needed) using the BPEL endpoint. <em>NOTE: this do not need changes in the BPEL engine configuration</em></li> </ul> <p>With this, you will have a very powerful platform to do orchestration that you can extend for more complex use cases in the future.</p> <p>Hope it helps ...</p>

    1. COAs I understand it, BPEL is indeed an orchestration engine used to create a business flow using webservices. However the business flows already exist in the services, I merely need to expose the "root" services of said business processes through SOAP so they can be triggered externally. Additionally the creation and management of said webservices must be fully programmatic.

    2. COBPEL can have pre-fixed workflows (as you described) or dynamic workflows based on dynamic bindings. This last one allows change the workflow based on the request. Now, *Change the workflow* means combine different 'base' web services at runtime (this is what you need right?). For the client of a BPEL service it will call a single 'root' SOAP web service (actually, the client will not know that is executing a BPEL workflow).

    3. COThe only thing that BPEL doesn't offer you is the 'fully programatic' root web service. But I do not get why you need that: there is nothing that you can do with JAX-WS that you cannot do with the XML descriptor of a BPEL workflow (regarding your use case). I strongly recommend you to read more about BPEL (and test it!) before trying to re-invent a BPEL engine by yourself, because satisfying your requirement is why BPEL was created for ...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
