I am working on a 3 tier architecture environment where the front end is JSP files. The JSP files are purely to get data from user and pass it on to EJB container. The EJB container will have the interface calls to post SOAP XML's to Backend system and acquire response back. I have WSDL file for for XMl formation. How to convert WSDL to Java and how to write stateless session bean to implement the request XML to post to backend system and get the response back. I want to call the EJB session bean from JSP as Remote access.
you can use standard oracle's JDK wsimport tool. Here is the good link with example www.mkyong.com/webservices/jax-ws/jax-ws-wsimport-tool-example/

I have recently encountered a problem statement ,there is a legacy code using soap based web service and ant as build tool.
My task is to convert the soap based web service to rest endpoint using spring boot and then end goal is to convert to microservice.
I have seen lot of articles where spring starter project is created with spring webservice dependency and they are also generating the classes through xsd's and using annotations like payload and SOAP configuration and checking the wsdl after running the application.
Is this the right approach to convert soap to rest but in my understanding it is simply creating soap web services using spring boot.
If we expose Rest Controllers with Pojos generated and generating the response type as xml or json ,do we need to do something apart from this to achieve the goal of converting soap to rest?
Any suggestions?
I am still exploring the working solution.
So far I have created the config client and server and I am thinking how to code inside the client code to expose soap as rest service.
I have a spring mvc application which runs correctly,now another colleague wants to call the same functions from another application but he needs REST URL of my functions.
how is it possible to provide the same functionality through spring REST?
is it just with new annotations .please provide some resource to show me how to do it.
when server has a service, only legal clients which had any contracts with server can access it. And clients can use service by the way such as: use RestTemplate to get/post request to URL of service, and clients can get data as JSON, or XML type if you have an equivalent object as this image:
Also, a service can be support as a interface, ex: google search is a service supported by google, but it's not rest service.
If you know each other URL address you can consume each other REST API from java code by using RestTemplate object.
I would advise you to go over the Spring starter guide which deals with that issue, here is the link (Consuming a RESTful Web Service):

I am working on sending a request to a web service and parsing the response. I have to use Spring 3 and Apache CXF. Using Maven's wsdl2java, I was able to generate request and response objects from the wsdl. These classes have been generated now and I see basically what appear to be annotated POJO's. I am unclear what the next step is to actually send the request to the web services. All I see is an ObjectFactory to create the initial web service.
What is the next step? Do I need to create a spring bean configuration file like this?
<jaxws:client id="XXXX"
serviceClass="XXXX"
address="http://localhost:8080/xxxx />
Any assistance would be greatly appreciates as I am not sure how to send the actual request to the web or what my next step would be. Thanks
If you want to look the webservice without using spring you can use the stubs generated & make a call to the service in a program with main. Something like..
http://61.153.44.88/apache/cxf/2.0/developing-a-consumer.html
If you want to use spring, see "Create a Client" section here
http://cxf.apache.org/docs/writing-a-service-with-spring.html
There is a post here with an example of how to create a CXF Client and server and integrate it with Spring.
im trying to understand where WSDL's fit in, in a typical web service backend application. i am coming from a Spring background and in my experience so far, in Spring, each url request gets mapped to a specific controller class via a dispate servlet running in the web container. you can specify which url matches a given controller via xml config or from annotations.
is using a WSDL the same thing as using an xml config file to map url requests to java objects?
Thanks in advance. im moving from Spring to standard j2ee/EJB3.
WSDL is just a description of Web Service interface, most Web Service systems generate those descriptions on fly like for example when you create asmx web services you can generate WSDL on fly by typing http://yourhost/yourwebcontext/yourwebservicename.asmx?wsdl and it will return you the description of that web service. Then you can use a tools that generate stub proxies for coding using those descriptions automatically, for example in Visual Studio when you add an Web Service Reference those operations are done automatically
No, WSDLs are not like a dispatch servlet.
A WSDL file is a description of a web service (SOAP, REST, etc.). A WSDL can (theoretically) be used by anyone to generate executable code which consumes the web service described by that WSDL.
From the WSDL tag info:
"WSDL" stands for "Web Services Description Language." It is an XML language used to describe a web service to code that wishes to consume it. It describes the messages sent and received, the possible faults, and the communication and security requirements.
From WSDL Essentials:
In a nutshell, WSDL represents a contract between the service requestor and the service provider, in much the same way that a Java interface represents a contract between client code and the actual Java object. The crucial difference is that WSDL is platform- and language-independent and is used primarily (although not exclusively) to describe SOAP services.
Using WSDL, a client can locate a web service and invoke any of its publicly available functions. With WSDL-aware tools, you can also automate this process, enabling applications to easily integrate new services with little or no manual code. WSDL therefore represents a cornerstone of the web service architecture, because it provides a common language for describing services and a platform for automatically integrating those services.
I'm trying to get rendered WCM content in an Asych bean (which implements the Work interface). I can create a Workspace using a username and password, but I don't see an API to create a RenderingContext without passing either a portlet request/response or a servlet request/response pair).
Is there any way I can either 1) Create a RenderingContext without a portlet or servlet request and response, or 2) Render WCM content in an asynchronous work bean some other way?
I'm using IBM Web Content Management, WebSphere Portal and WAS versions all at versions 6.1.x.
According to the API you can't get a RenderingContext without a ServletRequest or PortletRequest. You might need to make an http request back to the WCM servlet or write a web service that use the WCM API.
