AXIS2 Web Service in eclipse through Top Down Approach-java.lang.RuntimeException: Element QName is null

Based on this tutorial, But used my own WSDL file.
I used Top Down approach where to create java codes from the WSDL file. But at “Axis 2 Web Service Skeleton Java Bean Configuration” wizard window I clicked next and there occurred an exception as follows saying Element QName is null.

SOLUTION

Add the following XML element within
tags and inside
tag which has a wsdl:fault (Particular operation should throw an exception). So I had to add,
It appears as follows,

<binding>
         
  <operation name="GetBalance">
      <operation soapaction="http://it4110.itfac.mrt.ac.lk/2010/074005N/GetBalance"></operation>
      <input />
        
      
      <output>
        
      </output>
     <fault name="fault">
            <fault name="fault" use="literal"></fault>
      </fault>
    </operation>
  </binding>
Here the getBalance operation throws an exception, so for the wsdl:binding description the given element need to be added. Otherwise it gives an exception at Top Down Approach with eclipse.

PHP-SOAP web service with out a WSDL

This article is going to describe how to create a simple web service with php-soap step by step. Requirements     Server to run php (apache, xampp , wamp)     PHP-SOAP extension Steps Let's write a simple web service to find the length of a given string. So here is the code for StringLengthServer.php   <?php # StringLengthServer.php # Copyright (c) 2011 by Lakmali Baminiwatta #     function findLength($string) {            return "Length of the string " . $string .

Boomi Mapping - Removing special chars from an input

Image
Dell Boomi mapping shape provides numerous ways to modify/enrich an input via functions. In this post I am going to show how I validated and removed special chars from an input using Scripting and do it along with another string function. The user defined functions available with mapping, allows us to apply sequence of functions to the input. In this example, I am going to use it. Use Case: I have two input strings coming from the source profile (first_name and last_name), which I want to first concatanate together and then remove non-alphanumeric characters if present. Solution In your map, add an User Defined function and add two inputs; first_name, last_name.  Add User Defined function into the map Added inputs to the user defined function As the first step, add a function "String Concat" under the  "String" category.  Specify first_name and last_name as the inputs. Also set a delimiter, if you need a one. In my case, I want to concatena...

Boomi Mapping - User Defined function based on list of elements in a collection

Image
Recently I came across a requirement to validate all the elements in a collection and return an output based on that. Let me explain it with an example. I have a XML document containing information about users including a collection to indicate the roles of the person. Source Document <users> <user> <first_name></first_name> <roles> <role> admin </role> <role> subscriber </role> <role> creator </role> </roles> </user> </users> Destination Document I want to map this into a destination profile which has elements to indicate whther the user is an admin or a subsriber. <users> <user> <isAdmin> true </isAdmin> <isSubscriber> true </isSubscriber> <user> <users> </users> In order to achieve this I have to write a map funtion. But for a map funtion, we can't input a collection. If we map the "roles" collect...
