Web Services for Java Developers

Hello All and Welcome back. Today, we will take some time to discuss on Web services implementations. When ever we hit the Google button to search the Web Services implementation, we find many flavours of web services available on internet. Sometimes it becomes difficult to decide which implementation should we follow. There are bunch of services already present in the market which have gained so much popularity in terms of simplicity and their clear implementation. 

To deploy a successful Java based web service project, it needs end to end knowledge of the technology and the artifices that are used behind the scene to make your software run without any heck. When I started working on SOAP based service I had very minimal knowledge on the supporting specification and standards that are required for consume/expose the service. I have worked on both SOAP based Service as well as Restful service. 

In my up-coming blogs, I will be posting my understanding on implementation of web services and their uses.

We could say there are web services which are based on XML, SOAP or RESTful. There are many free and commercial implementations of services available in the market. To name a few :
WS implementation using Axis 2
SOAP WS implementation using JAX-WS
Restfull WS implementation using  JAX-RS Reference Implementation (called Jersey)
SOAP WS implementation using Apache CXF (formerly called XFire)
JBossWS
Spring WS
Amazon Web Services

Apart from above implementations we have some standard specification on top of which the web services are developed and exposed. For example :
JAX-WS, JAX-RS, JAX-RPC, Apache Axis, SAAJ, Apache SOAP etc.

As promised, going forward in couple of next blogs, I will be sharing how to implement SOAP/Rest Services and will also be showing you the unit testing of services using SOAP UI tool.

The step be step explanations may help you to develop your own web service. Please do not forget to post your query/suggestions.

Stay Tuned for upcoming blogs!!!!!

Know your Repository Statistics

Being in software development, everyone of us must be using some or the other repository to save our work( popularly know as check-in check-out :) ). Recently while working on one of my project I thought of finding out the statistics of our project repository for some management reports. While there are so many tools available in the market to explore the stats, I chose to go with Tortoise SVN tool with some plugins. Following are other tools that can be very useful based on scenarios: -Commit Monitor -Winmerge -Visual SVN -SVN Monitor -CM Synergy from Telelogic -Many more are there If you are using Tortoise SVN and want to know the details(for example : no of java classes checked-in, lines of codes written, developers name, total code base details and many more ) about your repository You can use the following steps to find the details: 1-check if the SVN has been installed and working properly or not by using following command: C:\>svn help It will output something ...

Testing your Webservice Applications using SOAP UI

SOAP UI is a standard desktop application for testing the Web Services projects. It provides full support for debugging, developing and testing of your web services applications. The tool support data driven development and also provides platform for creating test suites where you can create services for regression testing. For example if you want to test the complete flow of your SOA application, you can create Test Suites using SOAP UI and can perform end to end testing of your applications. The test suits can be configured to run in multiple environments (dev, sit, uat or production). Okay, let’s start the working on SOAPUI. I will show you the simple webservice testing that I developed in my last blog. Prerequisites: -You have developed your webservices -Webservice is ready and running on your local server -Installed SOAP UI tool Step-1 Download the SOAPUI tool Step-2 Open the soap UI Tool Setp-3 Right click on the project and choose New SOAP Pro...

It's All Mobile

In the digital era, where anything is available on finger tip and we want everything in our pocket, It will not be wrong to say that mobile devices have become our life line. These devices are impacting our lives on a daily basis. Today we have an app(as the modern world calls it) for everything. You name an application, its there on app store/play store. For any company(small or big), having a mobile application can be a smart way to connect with people and get started with their business very quickly.  I can say it has become a must first step for businesses to have mobile presence if they want to reach out to their customers easily and on time.
