I am new to ESB Mule, and i am trying to figure out how to utilize not to have point to point connectin for each webservice, i want to do the following:
1-Provide an XML SOAP webservice that will be consumed by different external clinets (XML SOAP and Restful client) and then send the message to an external SOAP webservice that is connected to ESB Mule.
2-Consume two websevices, but instead of having point to point connection, i want the client to consume web service through ESB Mule and then it will be routed to the desird external webservices.
Thanks for the help
i would suggest you start of by getting yourself a bit familiar with mule, you will find examples for your usecase here:

Am receiving the message "System.Net.WebException: The HTTP request was forbidden with client authentication scheme 'Anonymous'." when trying to call the web service at "https://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.php" using BizTalk 2013.
I've imported the wsdl directly from the site, creating the schemas and the bindings to make the call. The Send port is set up as WCF-BasicHttp, Security Mode: Transport, Transport Client Credential Type: None. I'm able to call the service using SOAP-UI from the BizTalk server, providing no form of authentication.
Have read numerous posts and documentation, but nothing I've done to this point has helped. I'm sure I'm missing something; just not sure what that something is!
From the looks of the WSDL: <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> it's an RPC type web service
Like the documentation specifies: 'The WCF adapters do not support consuming Remote Procedure Call (RPC)-style Web services because the message parts in RPC-style Web services are referring to the message types rather than the message elements where WCF adapters are using elements for the message parts. We recommend that you add the RPC-style Web services through Add Web Reference wizard for consuming the Web services in BizTalk projects.'
In my project I need to write a web service which will receive Collection<?> as a parameter.. I am using apache CXF.. After I have written the service method I am unable to test it using SOAP UI (It is not generating any request).. My question is - Is it possible to receive Collection<?> over web service? I need to receive Collection of any object type.. Please help..
You need to work directly with SOAP messages.
I've started learning about webservices recently. Have few question about that:
For webservice, is it always necessary that source should provide wsdl or any other way possible to consume it without needing wsdl?
Till a while ago, I was doing server side XMLhttp post in classic ASP to do modifications in external application & to push data in my application from external application. I'm confused - is that very different from webservice or can be called a sort of webservice(ofcourse without based on SOAP). Any major difference or it is just protocol difference bw webservice and server side XMLhttp post?
Web services can be made asynchronous?(Something like AJAX call through javascript)
Are there any different types of webservices ? (for e.g is there difference bw, webservice providing stock quotes and webservice provided by google)
1.For webservice, is it always necessary that source should provide wsdl or any other way possible to consume it without needing wsdl?
WSDL is a document that publishes an interface. As long as a client complies to the inteface, it is guaranteed to be able to "talk" to the web service. Having said that WSDL is a formal way for a specification when there are many stakeholders. You can proceed without one, as long as you somehow know what the web service expects. Just wrap the application data in a SOAP envelope and send it to the web service. As long as you send what the web service expects (in the SOAP envelope or the application data) and in the way they are expected e.g. transport HTTP etc. it does not matter for the WS if you have used a WSDL or not.

In very simple terms web service is XML over some application protocol (usually HTTP). Could be SOAP based or REST. To understand more on this you should read about Service Oriented Applications
3.Web services can be made asynchronous?(Something like AJAX call through javascript)
They could but it is more complicated than that.
4.Are there any different types of webservices ? (for e.g is there difference bw, webservice providing stock quotes and webservice

Not sure what you ask here. Each web service offers something.
I will try to be very simple here:
The W3C defines a "Web service" as "a software system designed to
support interoperable machine-to-machine interaction over a network".
That means first requisite for any software to be web-service is that it should not depend upon platform or software i.e a web service made on java stack can be consumed by client in .net stack on windows or java stack on android.
If your server side implementation XMLhttp post suffice this ,its a
web service.
Types of Web services
Actually, there is no overall and clear categorization on types of web services. But two most popular are :
SOAP based web services. :It use XML messages that follow the Simple Object Access Protocol (SOAP) standard, an XML language defining a message architecture and message formats(WSDL).
REST based web services. With evolution of WEb 2.0 emphasis has been moving away from SOAP based services towards representational state transfer (REST) based communications.[3] REST services do not require XML, SOAP, or WSDL service-API definitions.Read here to get a easy explanation of REST
Need of WSDL to consume SOAP web services?
To consume a SOAP service we only require SOAP endpoint and XML message format. WSDL is a pre-requisite for automatic client side code generation through Java and .NET SOAP frameworks.
Asynchronous web services
Making web services asynchronous is possible.But complexity depends upon frameworks used, for example AXIS2 in JAVA has easy implementation of this.
I'm trying to figure out how to forward web service requests from the web server to a remote application server through jms.
In my architecture there are web services client which communicate with some web server (Tomcat) which needs to forward the request to be executed on a remote application server and at the end get the result and push it back to the web service client.
Something like:
Web Service Client <-> HTTP <-> Tomcat <-> JMS <-> Application Server.
I want to use jax-ws so my methods will be called automatically in the application server.
Although I've expected this will be common approach, I didn't find any examples.
I would appreciate if someone can provide some links or tips on how such a configuration can be built.
Currently I'm using Metro but any other solution is valid as well.
Another aspect which I'm interested in, is whether I can use the fast-infoset over JMS to increase performance.
Thanks in advance,
Avner
you can try wso2MB as a JMS provider ...Check following links, would be useful
[1]http://wso2.org/library/message-broker
[2]http://pzf.fremantle.org/2011/04/introduction-to-wso2-message-broker_05.html
One option to solve it is using Apache Camel.
Then you can configure such a thing with an XML configuration file.
We have a web service which has been running on SOAP over HTTP using Apache CXF, and needs to be switched to SOAP over JMS. This is relatively new grounds for me and the internet didn't seem to give all the answers for me, or i couldn't understand much of it.
It would be really helpful if anyone of the experienced veterans explain the steps to get this conversion from HTTP ot JMS (in simple english which you guys do best) so that i could understand and implement it.
Also would like to get any info on checking if the SOAP over JMS is transparent (whether we could monitor the request & response).
Thanks in advance and cheers!!
The Internet can provide plenty of examples. Here is something to start:
SOAP over JMS by CXF and Advanced CXF configuration for JMS
The move from WS inbound call to JMS inbound message is quite transparent.
Simple high-level steps (in simple English to start with):
(a) Setup your JMS server
make sure it works by testing it - send messages to it using OpenJMS, Hermes, or some other client.
(b) In the CXF setup the connection to the JMS server and specific Queue
(c) Inbound messages: in your code, create an MDB (MessageDrivenBean) class, which is linked to the CXF connection setup
(d) Outboud messages: in your code, define a controller which uses the Context of CXF to get the connection and session to the JMS - and can send a message using them.
I'll be happy to hear how it goes.
