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

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.

JAX-RPC with attachments

I have a service that needs to return an xml document and an attachment. The service is implemented as a stateless session bean. The xml document contains meta-information about the attachment. I cannot find a good example or explanation on how to return both of these forms in a single response.
Can someone point me to an example, or provide an explanation?
Thanks,
Steve Pruitt

Hi Steve!
Have you tried to return a Source object as an answer?

Batch operations with JAX-RPC

I have read a number of different tutorials about Web services and JAX-RPC, and have to come the conclusion that JAX-RPC is the correct approach to use for my project. Most of the examples I have seen involve invoking services which perform a 'one-shot' action e.g. get a Stock Quote.
My first question is that I am not sure for such 'one-shot' services, how much support there is in the API for sending/receiving arrays of data items. e.g. sending a user's data to a web service which includes an associated list of phone numbers.
Further if I wanted to send user's data which included an array of nested objects, would I have to implement a serializer/deserialiser plugin?
My main concern really is how best to handle a batch of requests to the service. My current thought is to use JAX-RPC with an xml document attachment - listing of a number of user's data and their parameters. A 'batch service' would return a response immediately then work through the document and invoke the existing 'single shot' service - which will be hosted on the same web server.
Is this approach which brings together a number of different ideas from the various JAX-RPC tutorials viable? Are they any better alternatives?
For example would it be better to implement a JAX-RPC for the single shot service requests and use JAXM for batch service requests? (On the server-side I would still be expecting the batch service to re-use the single-shot service). Can JAXM and JAX-RPC services co-exist on the same web server? I realise that there would be WSDL generated for the JAX-RPC service alone and so for a client developer there will be an inconsistency in terms of how the Web service is accessed.
Thanks in anticipation

Hello, I'll try and go through your questions one at a time:
My first question is that I am not sure for such 'one-shot' services, how much support there is in the API for
sending/receiving arrays of data items. e.g. sending a user's data to a web service which includes an
associated list of phone numbers.JAX-RPC has built in support for List type operations. There is no problem sending Arrays of information over the wire. If you were sending an Object of type User, for instance, there would be no problem with User having a List of PhoneNumber types objects as part of it's structure.
Further if I wanted to send user's data which included an array of nested objects, would I have to implement
a serializer/deserialiser plugin?Condintional No. If the nested objects contained only data structures that JAX-RPC knows how to deal with, your fine (things like java.lang.String or java.lang.Integer). However, if your nested objects contain types that JAX-RPC does not know how to deal with (i.e. java.sql.TimeStamp), you will have to write a custom serializer/deserializer just like you would if you were passing those objects without them being nested.
My main concern really is how best to handle a batch of requests to the service. My current thought is to
use JAX-RPC with an xml document attachment - listing of a number of user's data and their parameters.
A 'batch service' would return a response immediately then work through the document and invoke the
existing 'single shot' service - which will be hosted on the same web server.
Is this approach which brings together a number of different ideas from the various JAX-RPC tutorials
viable? Are they any better alternatives?As per above you shouldn't have to send an xml document attachment, but I guess you could. Also, for batch processing type tasks you probably want to look at the asychronous mode mentioned in the JAX-RPC part of the JWSDP tutorial.
For example would it be better to implement a JAX-RPC for the single shot service requests and use
JAXM for batch service requests? (On the server-side I would still be expecting the batch service to re-use
the single-shot service). Can JAXM and JAX-RPC services co-exist on the same web server? I realise
that there would be WSDL generated for the JAX-RPC service alone and so for a client developer there
will be an inconsistency in terms of how the Web service is accessed.Well, it really is up to you at this point. I assume that you want/need to use web services for access (as opposed to EJBs or any other method). So, I would look at an asychronous web service implementation.

Newbie to attachment with JAX-RPC

Hi,
I am new to Web Services. I am developing a web services using oracle technology. I use JDeveloper 10g to create my web services using stateless Java class. Everything are so simple with clicking here and there to generate my WSDL file, web service stub and so on. Oracle use their own servlet as shown below.
<servlet-name>MyWebService1</servlet-name>
<servlet-class>oracle.j2ee.ws.StatelessJavaRpcWebService</servlet-class>I had created my interface and implements (Hello.java & HelloImpl.java respectively). Having a method public String sayHello(String param).
Now, I want to send a attachment (or more than one) to the client using JAX-RPC. My problem now is don't-know-where-to-start. I have gone through a few example but most of the examples are so misleading. I understand that the endpoint of a web services is from servlet. Am I suppose to start my coding to attach the document(*.doc, *.pdf, and so on) to the SOAP object in my Hello.java or HelloImpl.java? Correct me if I am wrong.
Anyone out there has a sample code of how-to send attachment with JAX-RPC with step-by-step (especially using oracle jdeveloper 10g if exist) article, if any?
Please help, I am lost. Thanks in advance.

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.

Weblogic 10.3 - Arrays and JAX-RPC Web Services

We are currently looking at migrating from WL 8.1 to WL 10.3, and have an issue with some of our web services (JAX-RPC) with regards to returning String arrays.
We have a web service method that returns a response object. This response object has many properties that includes a property that is a String array. So the code looks something like this (this is a simplified version):
public class OurService
@RemoteMethod
@WebMethod
@WebResult(name = "result")
public ResponseObject lookup(String someParam)
// build the object and its properties here...
return responseObject;
}
This is what the response object looks like:
public class ResponseObject
private String[] someProperty;
public String[] getSomeProperty()
return this.someProperty;
public void setSomeProperty(String[] someProperty)
this.someProperty= someProperty;
}
So the issue is this. In WL 8.1, the web service generator would recognise the fact that the response object had a property that was a String array and would declare as such in the WSDL file, for example:
 <xsd:element xmlns:tp="java:language_builtins.lang" type="tp:ArrayOfString" name="someProperty" minOccurs="1" nillable="true" maxOccurs="1">
</xsd:element>

As a result, when the service is called, the property is returned in the SOAP response like this:
.

<div class="e">
<div class="c" style="margin-left: 1em; text-indent: -2em">
 <someProperty soapenc:arrayType="xsd:string[2]">
</div>
<div>
<div class="e">
<div>
 <string
xsi:type="xsd:string">string1</string>
<string xsi:type="xsd:string">string2</string>
</someProperty>
</div>
</div>
</div>
</div>
.

But, in WL 10.3, the WSDL entry is:
 <xs:element maxOccurs="unbounded" minOccurs="0" name="InstepCodes" nillable="true" type="xs:string">

As a result the property is returned in the SOAP response like this:
 .
 <java:InstepCodes
xmlns:java="java:com.myservice">string1</java:InstepCodes>
 <java:InstepCodes
xmlns:java="java:com.myservice">string2</java:InstepCodes>
The difference here is that WL 10.3 does not return the array of strings as a complex array type, just as a set of repeated elements.
We need to return the array as we do for WL 8 in WL 10.3, because we have external clients that are parsing the response and looking for the XML in this format. We are not currently in a position to ask them to change.
Is this a limitation of the JAX-RPC spec, or WL's implementation of it?
If the service was to return a String array directly from a service method, then it is declared in the WSDL file.
However, if a service returns an object that within itself has a property that is an array, it does not recognise it like it did with WL 8.1.


<div class="e">
</div>

Thank you for the reply.
We are using WL Server 8.1 (not Workshop), and moving to WL Server 10g R3.
We are using the JWSC task to generate the service, which is:
bq. weblogic.wsee.tools.anttasks.JwscTask+
Here is an extract from the Ant build file the calls the task.
<jwsc
srcdir="src/com/ourservice"
sourcepath="src"
destdir="${ear.dir}"
verbose="false"
debug="true"
keepGenerated="true"
classpathref="ws.class.path">
+<module name="${service.name}" explode="true">+
+<jws file="OurService.java" type="JAXRPC"/>+
+</module>+
+</jwsc>+
As stated in my first post, the service method returns an reponse object and its this that contains the array property. The service method itself does not return an array type. This seems to be the root of the problem, i.e. the declaration of array types is not being propagated down through the object graph the service method returns. Below is the code for the service and the response object.
@FileGeneration(remoteClass = Constants.Bool.TRUE, remoteClassName = "OurService", localHome = Constants.Bool.TRUE, localHomeName = "OurServiceLocalHome", remoteHome = Constants.Bool.TRUE, remoteHomeName = "++OurService++Home", localClass = Constants.Bool.TRUE, localClassName = "++OurService++Local")+
@JndiName(remote = "com.ourservice.++OurService++", local = "com.ourservice.++OurService++Local")+
@Session(ejbName = "++OurService++", type = Session.SessionType.STATELESS, transactionType = Session.SessionTransactionType.CONTAINER, maxBeansInFreePool = "100", initialBeansInFreePool = "20", enableCallByReference = Constants.Bool.TRUE, homeIsClusterable = Constants.Bool.TRUE, homeLoadAlgorithm = Constants.HomeLoadAlgorithm.ROUND_ROBIN, isClusterable = Constants.Bool.TRUE, beanLoadAlgorithm = "RoundRobin", defaultTransaction = Constants.TransactionAttribute.SUPPORTS)+
+@RoleMappings( { @RoleMapping(roleName = "Admin", externallyDefined = Constants.Bool.TRUE),+
+@RoleMapping(roleName = "Monitor", externallyDefined = Constants.Bool.TRUE),+
+@RoleMapping(roleName = "JMS", externallyDefined = Constants.Bool.TRUE) })+
@WebService(name = "OurServicePort", serviceName = "OurService", targetNamespace = "http://www.ourservice.com/SOA/OurService+_service")+
+@SOAPBinding(style = SOAPBinding.Style.RPC, use = SOAPBinding.Use.LITERAL)+
@WLHttpTransport(contextPath = "OurService", serviceUri = "OurService", portName = "
*OurService+Port")+
public class OurService
+{+
@RemoteMethod
@WebMethod
@WebResult(name = "result")
{color:#ff0000}public ResponseObject lookup(String someParam){color}
// build the response object...
return {color:#ff0000}responseObject{color};
+}+
This is what the response object looks like:
public class ResponseObject
+{+
private String[] someProperty;
+public {color:#ff0000}String[] getSomeProperty(){color}+
+{+
return this.someProperty;
+}+
public void setSomeProperty(String[] someProperty)
+{+
this.someProperty = someProperty;
+}+
+}+
From all of this I cant tell how we get the WSDL file to delcare it as an array type, as shown in the JAX-RPC 1.1 spec you mentioned, based on the code we have and the JWSC build task we are using.
(I appologise for the formatting of this message. It seems to want to insert + everywhere in the code examples, despite me removing them!)

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.

JAX RPC extension: Problem with document/literal and MyType[]

Hi,
I have installed the JAX RPC extension and want to generate a stub from my WSDL file. The WSDL describes a document/literal binding.
Problem:
A webservice server method like:
public wineshop.model.common.SimpleProducer[] getSimpleProducerList() throws RemoteException;
is translated into a stub method like:
public UnknownType getSimpleProducerList() throws Exception {..}
Is an array of own types with the binding style "document/literal" not supported in JAX RPC 1.4 or is it just a bug?
The WSDL file is generated by JAX RPC 1.4.
I have installed JWSDP-1.5 and generated a stub with wscompile from the WSDL file. The generated stub has the correct method return type:
public wineshop.ws.client.SimpleProducer[] getSimpleProducerList()
throws java.rmi.RemoteException
It there a workaround like replacing some JDev JARs with JWSDP-1.5 to solve the problem?
Any hints are welcome.
Thanks Markus

How to pass SOAP Attachments with JAX-RPC Web Service

I'm confused...
This sample shows how to send/receive SOAP attachments by using the JAX-RPC Handler mechanism. Can somebody confirm if this is the preferred way to do this. I've seen an example wich does something like:
public interface AttachmentService extends Remote {
public String storeDocumentService(javax.activation.DataHandler dh, String filename) throws RemoteException;
}and then uses JAX-RPC utilities to create wsdl, stubs and stuff. Does this have the same result, as what the OTN example shows (from an architecture perspective?
Thx,
Jan.

Well, how an attachment is processed depends on your application logic...if your application logic requires to processing attachments and verify it before processing the SOAP message, handlers could be better option.
If you need to process the attachment while processing the SOAP message, you can do it in the service implementation class.
In both the cases you need to get access to SOAPMessage object and from there get the attachments with getAttachments method.

Hi,
I reselved the problem by just copying the FastInfoset to the jaxrpc\lib directory (I am sure this should work in a different way).
Well, the next problem I am getting is that the "XMLStreamWriter" class cannot be found. This class is contained in jsr173_api.jar.
I guess my main question is the following:
Which projects are necessary to get this simple helloWorld example to work?
I did set the JWSDP_HOME varible. Is there another setting I have to make to have all necessary jar-files available and to be able to run the samples?
Could anybody point me to a tutorial that does not only show a few lines of code (as the HelloWorld sample in the JWSDP-Tutorial) but that would instead lead me through a step-by-step sample application that I write by myself and actually runs at the end? The example in the JWSDP-Tutorial uses all kinds of existing config files which are not explained.
Thanks for your help.

Web Service JAX-RPC/SOAP with JAXB

Hello,
During my research on JAX-RPC/SOAP as web service technology. I found only simple "helloworld" sample type what using simple String as aurgment. For my task, I required a more complex aurgment such as a complete contact info. I then did some sample code for JAXB and found it to be very useful as a XML/JAVA binding tool. It seems logical to use JAXB to parse and bind the complex aurgment. Though I have not seen any reference to this using it with JAX-RPC. Does JAX-RPC have the tool set to accomplish the same thing? JAX-RPC may have such thing, but using this JAXB seem logical, thus would I still "conform" to the JAX-RPC if I go this route. Any info would be much appreciative.
Thanks in Advance,
Mike

The two JAX-RPC tools that I have used, the reference implementation and Apache Axis both have tools for mappiing XML to classes and vice-versa. Having used JAXB also, I have to say that both of these tools are much easier to use than JAXB.
As far as whether it will conform, you can make a valid SOAP message using any tool you like.
