Purpose of this blog

My name is Mikaela Poulymenopoulou and I have received a doctoral degree from the department of Digital Systems, University of Piraeus in Greece. My research interests include cloud services, service-oriented architecture - web services technology, workflow technology, systems analysis, project management etc.  My research area is basically on healthcare informatics including virtual patient records, healthcare workflows etc. Currently I am teaching at the Master degree of the department Digital systems of the University of Piraeus.
During my research, many times I faced the difficulty of finding the most appropriate software platform to implement my research scenarios. But either afterwards many times I have to test different software platforms to choose which fits best for the lessons I teach. Unfortunatelly, it is very often the lack of free software documentation and tutorials on how to install and use a software platform. Because there is no need for everyone to reinvent the wheel I decided to create this blog to write and help other people, too, to find information, examples and comparisons among the software platforms I have used and tested.

IBM WEBSPHERE STUDIO APPLICATION DEVELOPER AS A TOOL FOR WEB SERVICES DEVELOPMENT

IBM WEBSPHERE STUDIO APPLICATION DEVELOPER is an eclipse-based platform that can be used for easily building java-based web services. It offers wizard that can be used for transforming a java code into a web service. This wizard creates the WSDL file of the new web service. There is also one wizard that can be used to create a web service client. This wizard takes as input the WSDL file and creates four jsp pages that can be used as a simple web service client to test the web service.

Here is an example of a java code with four functions and its corresponding WSDL File created with the wizard Deploy as Web Service. This wizard can be found by right clicking on the java code file under the menu Web Services. Notice that is best to create a package to put your java code inside and use always lowecase on the first letter of your package name.
