Diff between JAXM & JAX-RPC

what's the difference between JAXM & JAX-RPC ? How to choose between the two ?

hi,
You can simulate the request-reply type call in JAXM also.
So if I have to ans it again I will say JAX-RPC uses JAXM to execute the rpc call.
Also through JXM alone you can simulate the RPC call Through SoapConnection. I dont know if it can be done through ProviderConnection . I have yet to explore it.
Still I am confused why JAX-RPC is considered as a separate API.

JAX-RPC with JAXM?

I have already created a synchronous messaging client using JAX-RPC. I now find the need to also have a asychronous messaging client as well. I was not able to find much as far as information or examples of asynchronous messaging. The only information I was able to find just says that I should use JAXM. The question I have is can I combine the JAX-RPC and the JAXM together (I'm using tomcat). Also does anyone know of a good asynchronous messaging example using either JAXM or JAX-RPC?

JAX-RPC or JAXM or AXIS/GLUE

Hello,
I am starting with webservices and am confused with all the APIs out there. Should I start with JAX-RPC or JAXM to develop/consume webservices? Do I need SOAP implementations like AXIS or GLUE?
Please Help !!!
-ss

Yes, it's pretty overwhelming when you're first starting out. My suggestion is to start with JAX-RPC because:
1. it's easy to understand
2. most existing web services are RPC-based
3. there are many nice tools to help you create JAX-RPC based services
Now you can decide which JAX-RPC implementation to use. Both JWSDP and Axis have JAX-RPC implementations. JWSDP is nice everything-rolled-into-one installation, so it's a good platform for learning (the tutorial version 1.2 isn't available yet but most of the 1.1 tutorial applies to JWSDP 1.2). Just download the JWSDP 1.2 installation package and the tutorial and you're ready to go (Tomcat is bundled with the JWSDP).
However, I believe that many more commercial web service implementations are based on Axis than JWSDP. If you plan on deploying web services yourself, you may want familiarize yourself with Axis. Just download and install Tomcat, then download and install Axis. The axis-user mailing list at http://ws.apache.org/axis/mail.html is very helpful.
And don't worry too much about which package is better. Any services you develop with either platform can be ported unchanged to the other.
Good luck,
Mike

JAX-RPC, JAXM, JAXR supported in WLS6.1?

Does wls6.1 support JAX API's? If not, when will they be supported? Thanks much.
Siming

Hi Siming,
The JAX Pack (i.e. JAX-RPC, JAXM, JAXB, JAXR, etc.) are still merely JSRs, with
no "real" consensus on whether they will ever be otherwise. This being the case,
it is unlikely that you will see support for them in WebLogic Server, in the near
future (3 to 6 months). You can always run the Sun RIs (Reference Implementations)
under WebLogic Server (I have done this with both JAXB and JAXM), if you would
like to experiment with these technologies.

Mike Wooten

Apache axis, JAX-RPC, JAXR, JAXM, JAX-WS, JAXB, and Metro

Are all of the following the different APIs for creating web service applicaton?
Apache axis,
JAX-RPC,
JAXR,
JAXM,
JAX-WS,
JAXB, and
Metro
--If so, which one(s) are most widely used?
--If not, what are the differences among them?
Thanks
Scott

I think your are looking for a full web services framework.
Apache axis --> Is a WS framework. implements jax-rpc. Provides some features on its own
JAX-RPC --> Is a WS framework specification. Your application servers/axis implement this.
JAXR --> not an web-service api, rather a web-service registry access api
JAXM --> Is an api for xml messaging. Your framework provider may use this.
JAX-WS --> Is jax-rpc 2.0. Your application server provider will give implementation for this. Otherwise you can use xfire/metro as the implementation. Chose this over jax-rpc.
JAXB, --> Is used for xml-java binding. Jax-ws uses this. But not specific to jax-ws..
Metro --> Reference implementation for jax-ws.
All in all jax-rpc, jax-ws and axis2 are three options. go for jax-ws if you do not have any other constraints.As for selcting implementation of jax-ws, if you are working on an app-server (and not on a simple servlet container or without a server), server vendor will provide that. Otherwise look for xfire or metro.

What is the difference between RMI and JAX-RPC?

Dear All
First of all my understanding of RMI and JAX-RPC:
RMI is JAVA only version of RPC. It can't talk to any other language.
JAX-RPC is a part of JWSDP and if you implement your client and server with JAX-RPC, client written in any language can talk with JAX-RPC implementation.
What else makes them different and am I right with my understanding?
Finally, I would like to develop clients which will have a java class, say httpserver.java, which will act like a http server, listens to a http port. Now, Two such client will run in two different PC and I want to call a module from one client to another which should be accessible via my httpserver.java. For that which should be my choice RMI or JAX-RPC? Can I achive it with http get-post method, as I am expecting to read some value of variables from one client to the another.
Say class A has variable a, aa, aaa and clas B has variable b, bb, bbb. Now I want to read the value of b, bb, bbb from class A. How do I do that when class B is listening to a http port with my httpserver.java class.
Lastly, say B is listening to a http port and I want to send a file to B from A. How can I do that? Remember, B didn�t ask for that. How can A send a file to B when B is listening to a http port with my httpserver.java.

simply put, RMI allows you to (semi) transparently treat remote objects as if they were local, and your distributed application can be written (more or less) like a "normal" java app. Sockets just give you a "raw" connection to work with, and you get to build up your application from that.
I hope that helped

Intercepting SOAP XML message in JAX-RPC Handler and calling a diff method

Is it possible to intercept the SOAP XML message in the JAX-RPC handler and avoid the serialization and deserialization (OR avoid XML data binding)
Here is a more detail question
My web service has two methods
1. One Method which accepts Java Object (this object is mapped with a Schema
Complex Type Element in my WSDL file)
2. Second method which accept simple String type.
I want my web service client to send java object (using the first method), so that the Input gets validate in the WSDL itself (before it hits the actual web service) but once the request gets validated i want to pass that converted SOAP XML String (on the Server side using JAX-RPC handler) to the Second method.

The answer to this is that the WSDL had
elementFormDefault="qualified"
in the schema.
Changing to unqualified resulted in the desired output.
Note: The service was changed to handle both cases.

XML Comments in SOAP message - jax-rpc

I ran across an issue with comments in my soap messages with regards to the serialization.
My solution was to strip all the comments inbound and outbound.
Are xml comments supported by JAX-RPC? I am currently scouring the internet for more information, but the closest I have come is a reference in the IBM implementation which doesn't really help me out.
Any thoughts are appreciated.

I'm trying to figure this out myself. I am using JAXM to access a web service but it wants the xml version...

JAX-RPC And Non-Java Web Service

Hi,
This is a total shot in the dark. I'm attempting to consume an RPC web service developed in Delphi. I've created a JAX-RPC client in NetBeans from the published WSDL, attached below. I've created calls to several of the procedures available. What's bizarre, at least to me, is that half of them work fine and half of them don't. In all cases where they don't I'm getting a returns SOAP envelope indicated an access violation, attached below. There are no errors in any of the server logs and the developer assures me that the procedures do, in fact, work from his client (also developed conveniently enough in Delphi).
I'm willing to take him at face value for the moment and assume that the problem is in my client implementation, although I have no idea where it would lie. The only difference I've been able to gather between the features which work and those that don't is the size of the return package...it would most likely be much larger than the ones that don't work.
The service is an ISAPI dll running under IIS on Windows Server 2003. Any clues or guidance anyone would be willing to provide would be most welcome. On to the files:
There wasn't enough room to post the entire thing so I've included one working (CheckStock) and non-working (GetLibTrace) function.

One project with two different web services styles (JAX-RPC and JAX-WS)

Hi theres,
how come the same project doesn't support two different web services styles?
First time I create a web service proxy using the wizard, the second step is to choose between JAX-RPC and JAX-WS. After that, this step is removed from the wizard and all subsquent web services are assumed to be the same style as the first one.
Can someone explain me why?
thanks in advance,
Manuel Leiria

Hi,
yes, I think to remember that there is support for a single style only. If you need another one too then you create a new project.

JAX-RPC and Parameter Interfaces

I am designing the Web Service interface for our project using JAX-RPC, and have enjoyed the ease with which I can create Web Service deployments and WSDL documents.
However, some of the developers on my team have chosen to create their Data Transfer Objects as a pair of Interface and Implementation classes. This works okay in scenario where the WS caller is "pulling" data from my service. However, it doesn't work in the scenario where the caller is "pushing" data to the service because JAX-RPC can't make the connection between the interface and implementation classes used in my service interface.
For example, suppose there are four classes in the project: MyService, MyServiceImpl, Foo, and FooImpl. The MyService class uses Foo in it's method signatures. How does JAX-RPC know to instantiate an instance of FooImpl for incoming requests?
public class MyServiceImpl implements MyService {
// not ok
public void doStuff (Foo arg) { ... }
// ok
public Foo giveMeStuff () { ... }
It would be nice if JAX-RPC provided annotations that facilitated making connections between interfaces and implementation classes used in service inputs and outputs. For example:
@WebServiceInterface {
Implementation=FooImpl
public Foo {
Any thoughts? Thanks,
Scott Kidder

Asynchronous JAX-RPC Web services

In our application we would like to make a non-blocking call
to a single web service ( so we don't need to use BPEL).
Do you have a pointer to the document about creating Asynchronous JAX-RPC Web services and writing client code?
Thanks!
-- Qun

Yes interoperability is the biggest advantage you get with JAX-RPC services.
JAX-RPC spec (JSR 101) defines a standard way in which a web service should be written so that it interoperates between different application servers. It does away with the vendor specific api's and implementation of web services.

Observations/questions on JAX-RPC

I started developing Web Services on Oracle 9iAS (9.0.2.x). What impressed me is how easy it is to turn any old class into a Web Service; you can focus on and develop the API you want, in relative ignorance that the class is being exposed through SOAP. The whole SOAP layer, including [de]serializing parameters and return values, making the HTTP connection, etc. is provided by the container and the auto-generated client stubs.
Oracle 9iAS, and earlier versions of WebLogic (6.x) seem to pre-date JAX-RPC and don't have a standard API for client stubs. WebLogic 7 seems to have adopted JAX-RPC, though, and hopefully other vendors will follow suit; it will nice for all client stubs to have the same methods for setting the URL or a username/password.
I did notice some important differences between Oracle Web Services and JAX-RPC, though:
- Oracle and WebLogic both provide for the direct exposure of stateless session EJBs as SOAP services. The JAX-RPC reference impl (JWSDK) seems to only provide for the exposure of regular Java classes, and exposing an EJB requires an intermediary Java class to find and call the EJB in question. Is it the intent of the JAX-RPC standard to allow for vendors to directly expose EJBs, while just omitting this as a feature for the reference implementation?
- Oracle also does not require an explicit step to generate client stubs and WSDL. It can generate these dynamically at runtime inside the servlet engine, and makes these available for download from the service itself. Can this style of auto-generation play nicely with JAX-RPC?
I also have some questions about JAX-RPC:
- if java.util.Calendar objects are serialized and deserialized by JWSDK, does that imply that java.util.TimeZone objects are as well?
- can someone point me at where the standard for exception handling and transport is documented (what exception do services throw, and how are they translated to client-side exceptions)?
- when the client stub is generated, does that also create client-side skeletons for each user-defined datatype (bean) used as an argument/return type for the service? Can these skeletons be made to implement a particular interface? One of the annoying things about Oracle 9iAS Web Services is that you can't use a client skeleton and the actual (server) bean object interchangeably even if the same get/set method exists on both objects, because the skeleton objects don't implement any interfaces.
Thanks!

Hi,
I will share with you... what I understand and know ...
- Oracle and WebLogic both provide for the direct exposure of stateless session EJBs as SOAP services. The JAX-RPC reference impl (JWSDK) seems to only provide for the exposure of regular Java classes, and exposing an EJB requires an intermediary Java class to find and call the EJB in question. Is it the intent of the JAX-RPC standard to allow for vendors to directly expose EJBs, while just omitting this as a feature for the reference implementation?
Well jsr 109 opens up the possibility of having stateless
session beans as end points. Naturally to stay aligned with
this jsr 109, lot of application server vendors have started
to support this.
The JAX-RPC ri that you are looking at was releazed befor JSR
109 spec was solidified and the ri gets released.
- Oracle also does not require an explicit step to generate client stubs and WSDL. It can generate these dynamically at runtime inside
the servlet engine, and makes these available for download from the service itself. Can this style of auto-generation play nicely with
JAX-RPC?
You should check out the next version of j2ee ri.
Some of your questions might get address there,
- if java.util.Calendar objects are serialized and deserialized by JWSDK, does that imply that java.util.TimeZone objects are as well?
Have check out the jsr 101 Chapter 19 ? That should answer
your question. You can get it from www.jcp.org
- can someone point me at where the standard for exception handling and transport is documented (what exception do services throw, and how are they translated to client-side exceptions)?
http://java.sun.com/webservices/docs/1.0/api/index.html
Check out the javadocs at the above location of service specific exceptions.
Also check out 8.2.6 from the spec it might help a little.

Sun's jax-rpc V.S Apache XML-RPC

Anyone can enlighten me with the differences between these two? which one is better?

I too am interested in the opinions of this post. After doing the research I see that for ease of implementation, it looks like XML-RPC is easier/faster to implement, however generates overhead through the creation of the servers to run such. On the JAX-RPC side, I find it not quite as easy to implement, and instead of it's own server it generates a full-fledged web service.
After looking through these it appears to me that if you want to use one of these for standard RPCs than it would be best to stick to the more mature java.rmi implementations; and if you want to create webservices, jax-rpc definitely helps.
Am I correct in saying this or am I missing another side of things as well?
I would enjoy seeing other's opinions of such.
