Working with XSLT Service Engine: Part 2

Project summary: In This project, I am going to do xml to xml transformation using Service Bridge. Please Check working with XSLT Service Engine Part 1 for more details about XSLT Service engine and sample project for Request-Reply service of XSLT service Engine. In this sample project I am going to take customer information like Name , Address , Personal Data in separate node and then merge all above info in single node. Creating Sample Project Using   Service Bridge (xml to xml transformation) In Service Bridge we can apply multiple xml transformation on request xml and then send output back to source. We need to have same number of wsdl operation as number of transformation we want to do. In this project I am going to apply two xml transformations. So I need to create two wsdl as webservice operation to perform transformation. Let’s  say Request1 and response 1 – first operation Request2 and response 2 – second operation Client will send request via request 1 and response 1 will get back to client but over all process will something like this . (Client input xml)Request1–>apply xsl on input to generate request2–>  request 2àappy xsl on request 2 generate response 2–>  response 2 –> apply xsl on response2 to generate response1 –> response 1(client output xml). Create XSLT Module: Please refer to part 1 for details to create XSLT module. Create XSD for request and reply operation <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://xml.netbeans.org/schema/CustomerDetails" xmlns:tns="http://xml.netbeans.org/schema/CustomerDetails" elementFormDefault="qualified"> <xsd:complexType name="CustomerName"> <xsd:sequence> <xsd:element name="firstName" type="xsd:string"/> <xsd:element name="lastName" type="xsd:string"/> </xsd:sequence> </xsd:complexType> <xsd:complexType name="CustomerAddress"> <xsd:sequence> <xsd:element name="HomeAddress"/> <xsd:element name="OfficeAddress"/> </xsd:sequence> </xsd:complexType> <xsd:complexType name="PersonalData"> <xsd:sequence> <xsd:element name="gender" type="xsd:string"/> <xsd:element...

Working with OpenESB WLMSE

Overview Here we will attempt to create simple Application that demonstrate use of WLM Application. Before we begin, quick introduction to WLM is appropriate. WLM stands for Worklist Manager. It allows you to create Web Service Application that require human action/decision (one of pre-defined options) based upon some input data. So, in nutshell, the WLM application can be fed messages (predefined type) and exposes some API’s (can be used to build Web Interface) that allows assigned user’s to see the requests as list of tasks for some actions/decisions. The resulting choice of the user will be sent back as output message (again pre-defined type) to calling service. The service interface is defined using WSDL and the communication is Synchronous. WLM application can be best thought of means to incorporate human step in an automated process. For example, if you need to incorporate human approval step in you BPEL Process, you can achieve this using WLM Application. It also provide features such as Task Escalation, Notification etc. This is what we are going to do in this Helloworld Application. A WLM Application has three components: Please refer to Downloads for required components download Design Time You can use Netbeans (download page) with SOA Modules and create WLM Project type. Using worklist editor, you create task definition wherein the aspects about the task definition is specified. More on this later. Runtime The built project is deployed on Glassfish with JBI Runtime Environment. Project Open-ESB provides a Service Engine called sun-wlm-engine which provide runtime implementation for WLM Projects. Web Application The Users of the Task can log on to Web Console and...
