RE: SOAP over JMS

Sanjeev,
1) Your use of the soap action is incorrect.      Normally, the soapAction 
value is specified in the WSDL being used by the client application.   It 
may be omitted however.   If specified in the WSDL, then the value would 
be sent (by the underlying runtime) across the transport (HTTP or JMS) in 
addition to the SOAP Envelope and would then be used by the server as a 
means of correctly targetting the request.   There may be other uses for 
soapAction or there may be other ways in which it is used by the server, 
but I'm describing it from the standpoint of a Java EE-compliant 
application server.
In your example, your client is calling the 
"Call.setTargetEndpointAddress()" method and you should pass in a URL 
object which is the JMS-style endpoint location URL for the request (e.g. 
"jms:jndi:jms/MyQueue?jndiConnectionFactoryName=jms/MyCF")

2) I'm not aware of any generally-available web services that use the JMS 
transport.   And I think the reason for this is that a web service 
application that uses a messaging-type environment (as opposed to HTTP) 
would most likely be entirely behind a company's firewall and 
self-contained within that company's intranet.      I don't think you'll 
find many messaging-type applications that are available on the "galactic 
internet" so to speak.

RE: SOAP over JMS



Phil,
 
1.       So I guess the value of soapAction attribute in the WSDL has to 
be used while constructing  SOAP service call  as below(even though it is 
using JMS transport).  Please correct me if I am way off base.
Service service = new Service();
                  Call call = (Call) service.createCall();
                  call.setTargetEndpointAddress(new 
java.net.URL(“soapAction”));
 
2.       I would like to test my client by connecting to a JMS webservice. 
 Wondering if there is any webservice exposed with jms transport, for 
public usage.  If so could you please send across the WSDL and 
corresponding sample request ?
 
Thanks in advance,
Sanjeev

1) The soapAction value is not specific to either the HTTP or JMS 
transport.   The soapAction value of "http://example.com/GetLastTradePrice

" is perfectly valid to use for an operation that will be invoked with 
SOAP/JMS.   The fact that it starts with "http:" is merely a coincidence 
and does not necessarily mean that the HTTP transport is used to invoke 
the operation.   soapAction is independent of the transport and is simply 
used as a means for identifying the operation that should be invoked on 
the server. 

2) The "targetService" property in the endpoint location URI is used to 
specify the name of the port component that is the target of the request 
on the server.    This value is used by the server to determine which web 
service implementation class is used (among other things).     In 
practice, the port component name is sometimes (or even often times) the 
same as the WSDL port name, but it doesn't need to be the same.   The port 
component name must be unique within the application module (EJB jar, WAR 
file, etc.) in which it is contained.    To determine what value you 
should use for this on the client, you'll need to inspect the service to 
see what the port component name is.    This is part of the JSR 109 
deployment model.     If, on the other hand, you're not using or concerned 
with a Java EE compliant runtime, then you can likely omit the 
targetService property from the endpoint location URI.

Hello Phil, 
  
Thank you very much for prompt response.  Those are the points that I am 
looking for. Appreciate your time in clarifying my questions.  For further 
understanding, would you mind helping with following questions ? 
  
1.       Can you please provide jms action snippet equivalent for 
below(http coincidence is little confusing me): 
  
<operation name="GetLastTradePrice"> 
         <wsdl11soap11:operation soapAction="http
://example.com/GetLastTradePrice"/> 
         <input> 
             <wsdl11soap11:body use="literal"/> 
         </input> 
         <output> 
             <wsdl11soap11:body use="literal"/> 
          </output> 
       </operation> 
 
2.       Can I have port name &  targetservice with same name as below ? 
<wsdl11:port name="stockquote" binding="tns:StockQuoteSoapJMSBinding">
          <wsdl11soap11:address location="jms:jndi:myQueue?
targetService=stockquote"/>
</wsdl11:port>

Sanjeev, 
The fact that the soap action value "looks" like an HTTP url is just a 
coincidence.  It doesn't  mean that it is related to the HTTP transport 
per se.    The soap action value is simply an identifier for the intended 
action (e.g. operation). 
As for your second question, I assume you're referring to this from 
section 3.4.1 of the binding spec: 
40       <wsdl11:port name="StockQuotePort_jms" 
binding="tns:StockQuoteSoapJMSBinding">
41           <wsdl11soap11:address location="jms:jndi:myQueue?
targetService=stockquote"/>
42       </wsdl11:port>

In this example, the targetService property indicates the name of the port 
component which is the target of the request.

Phil, 
 
I would be glad if someone from the group could answer below questions. 
 
1)      I am wondering about   the presence of http in SOAP Action 
attribute.  For JMS transport,  do we need to have  http action ? 
25         <wsdl11soap11:operation soapAction="
http://example.com/GetLastTradePrice"/> 
 
2)      What does last parameter (after ?) in address location stands for 
? 
 
 
Thanks & Rgds,

Hi Sanjeev, 
Well, I certainly wouldn't want to be in a position to have to implement 
all the SOAP processing from scratch.   Have you looked into the use of 
one of the open source engines, such as Axis2, etc.?    In fact, I think 
Axis2 already has some sort of SOAP/JMS implementation, although I don't 
know if it supports the SOAP/JMS binding spec just yet.

Hi Phil, 

Thank you very much for the response.  It was my mistake that I did not 
put up my question in right way.   In fact my component should do both 
functions i.e SOAP sending node & SOAP receiving node.  At this moment I 
am stuck with SOAP sending node implementation of constructing SOAP 
request message based on any given WSDL.  It would be really helpful if 
you can post a sample pseudo code(with respect to any existing soap/jms 
WSDL, to connect & test as well) for SOAP sending node implementation. 
Appreciate your time.

Hi Sanjeev, 
It sounds like you are implementing (more or less) the "SOAP receiving 
node" as described in the SOAP/JMS binding spec.   Note that the WSDL 
binding section of the spec really doesn't apply to the SOAP receiving 
node, since the WSDL is used by the client runtime (SOAP sending node) to 
construct the request message.    So you basically just need to receive 
the JMS message off the queue or topic, then use the JMS message 
properties (e.g. SOAPJMS_contentType) along with the body of the message 
(the format of the body will be described by the SOAPJMS_contentType 
property value) to de-serialize the request.   Then you would process the 
request and construct a response message and send it back in a JMS message 
according to the rules laid out by the SOAP/JMS binding spec.    The 
hardest part (IMO) is the message de-serialization step, although the code 
used to do that would basically be the same that's used to de-serialize a 
message received via HTTP so if your component already supports HTTP, then 
you are mostly done :)

Team, 

I am developing a standalone component, which would pick soap/jms message 
from a destination, processes it (webservice call) and then returns the 
response to reply destination.  Could you please give me pointers about 
java implementation by looking at WSDL.  Wondering whether it would be 
normal http webservice rpc/document invocation using soapaction mentioned 
in line-25, after picking up request message.  Any help is appreciated.
