3. WS Interface question    coderanch.com

Paul, Can you comment on a question we have about a Web Service interface, please? Perhaps your chapters 10-15 related to this? The question began with this: Originally posted by Pradeep Bhat: A service endpoint interface must not have constant declarations, such as public final static. Why is this so? My first answer was like "...interface is stateless, so there ...

4. WS for appliances    coderanch.com

Paul, One last question. I have seen commercial projects in which a traditional appliance (a toaster, a photocopier, a car) is being retrofitted for communication with the web. In these cases, it has been architected as a Web Service hosted at the vendor's (or representative's) site. Each appliance contains a newly added WS "client" with sensors and actuators. Simply speaking, the ...

13. RPC/literalor, Document/literal and WS-I Basic Profile    coderanch.com

That's mostly because the SOAP spec if fuzzy about encoding. So each implementation can have its own way to represent, code and decode data. This can lead to serious interoperability problems. Let's take a simple example : a String parameter. The SOAP spec allows different representations of a String object (both are correct): * SOAP-ENC:string * xsd:string So imagine you're consuming ...

Hello all, I have a Web Service deployed behind some security software (Actional) that performs WS-I validation on messages as they pass back and forth. We deployed a new method to an existing web service, and I started getting error message from the WS-I validator about that only HTTP 1.0 and 1.1 were supported by WS-I. I did some checking and ...

21. WS-I monitor?    coderanch.com

I'm not sure what you mean by "WS-I monitor". If you want to monitor SOAP messages flowing back and forth, then Axis has two for you: TCPMon is a standalone application, and SOAPMonitor is a JAX-RPC handler for the server. Both are mentioned (and described, to a degree) in the Axis user guide. The Web Services FAQ, which is linked in ...

22. Recommend WS Books?    coderanch.com

I've noticed that most of the Java Web Services books seem to take a lot of negative hits from the people who've posted reviews on Amazon. Plus, there don't seem to be any really new ones. Most of the reviews, for example, say the existing books are "obsolete". Based on what I've read here today, I'm going to install Axis on ...

35. Basic question about what a WS can return.    coderanch.com

If the object is a bean (i.e., there are appropriately named getters and setters for all the fields), you could use the java.bean.XMLEncoder and XMLDecoder to create an XML fragment that can be transferred over WS. Some SOAP engines (e.g. Axis) even have built-in serializers for beans, so you wouldn't have to do anything special in your code. Alternatively, at the ...

I've written a simple WS in Java that returns an array of objects. The finder method takes a specific object of type SiteSearch and returns an array of SiteInfo[]. What I was wondering is if a client connects via .NET will these objects translate into usable pieces? Or will the data be lost in translation? If so what is the best ...

38. WS Packaging    coderanch.com

I've written a basic WS that uses transfer objects and found that I could only package these objects in the base directory, com.ws. If I put the objects in their own dir, com.ws.model, the client which discovered the WS would put the classes in com.ws and the compilation would fail. Is it possible to package the transfer objects in their own ...

43. WS Vs SOA.    coderanch.com

Theoretically one could implement an SOA on top of services built using a different distributed technology (e.g., sockets, RMI or Corba), but that negates many of the architectural advantages that WS bring to the table. And, of course, WS are being implemented using other transports (Axis also has SMTP and JMS bindings), so the "W" in WS doesn't quite fit any ...

Many sources make it quite clear that the use of web services (WS) does not automatically lead to a Services Oriented Architecture (SOA) and that web services are merely an enabling technology for SOA.
