I wanted to use all the wso2 functionalities from my own customised UI. Is it possible to do so? If yes, them how to do it?
The scenario is: I don't want to use the available wso2 pages instead I wanted to have my own theme. How to do it?
WSO2 products up to carbon 4 are based on carbon osgi services. These services exposed as SOAP web services which known as admin services. You can refer WSO2 IS documentation to get idea how those can be enabled to outside and invoke [1]
You can create any application and invoke those SOAP web services. Although there are workarounds to invoke SOAP web services from HTML JS, best approach would be use a server side language like JSP and invoke web services from there. From front end HTML JS, you can use AJAX to call those JSP resources.

If you are referring to your own UI like the BPMN explorer that ships with WSO2 BPS, you can use the BPMN REST api [1] for this. This documentation [2]explains how the existing UI works. You can build your own by invoking the Rest API.

I have to create 2 projects. Web Service and one is Web project.
I created the web service using Rest in spring boot and web project using dynamic web project using Jsp and servlets.
Now I have to consume the web service in web project. How can I do ?
You can do AJAX call from your JSP side to your REST server side using Javascript. You can also use library like JQuery or axios (there MDN versions since you are using JSP) to send REST API calls to your same or any other server. You can follow https://stackoverflow.com/a/44859872/8684299 this answer.
We are using SAP S4HANA SDK Springboot archetype to build the application in SCP Cloud Foundry.
The requirement is to fetch the OData services from the SAP S4HANA and expose them to the Fiori UI frontend in the form of OData.
From the Java web services, we are getting the responses in JSON format:
Output what I need is in the below oData format.
This is one of the services and the same should be made available to all the java rest services. Found out Apache Olingo for converting it into odata format. But wanted to know if there is any method class in SAP SDK which supports this.
There are several possibilities to solve that problem:
You can fake it, i.e. manually translate all the results into XML yourself just enough so that UI5 accepts it.
You can expose an OData service from your backend using the SAP Cloud Platform SDK for Service Development (that is already modeled as a dependency of the SAP Cloud SDK). You can find information on how to do that here and also here.
Have you considered calling the OData service from your frontend directly?
I need some pointers for embedding an external web portal inside our web application. our web application is built on struts, spring framework. We need to integrate an external tool with our application. We need to pass certain parameters to that external tool and handle the response as well. There requirement is to show external web portal screen inside our application. How can we achieve this?
Could anyone please provide pointers on this?
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 want to write a ruby web service client for a SOAP (JAX-WS) web service. I looked into soap4r and handsoap but couldn't find useful resources to write a (JAX-WS) client
Can you help me to find some resources and some way of doing it. Because as I can see, my web service is developed using oracle JDeveloper and looks little different than examples find in web.
I'm a beginner for SOAP, WSDL web services and finding it hard.
Has anyone done something like this before, or can you turn me to the correct direction?
JAX-WS is an API for the development of web services in Java. Know then that, in order to consume a SOAP/WSDL based web service, it is not necessary to know how that web service was implemented. It could be Java, .NET or any other number of languages. All that is required to create a SOAP based web service client is the WSDL for the service. It is self contained and self descriptive, including all operations and data types supported by the web service.
In order to familiarize yourself with web services, I would recommend trying to exercise some web services directly, for example using SoapUI. This will allow you to import a WSDL for an active web service, try out some of the operations, and see what the corresponding SOAP messages look like. Then, I would look at "What's the best way to use soap with ruby?" for more ruby specific approaches.
