JUnit issue with Eclipse and Maven

In this post I am trying to resolve one issue of JUnit with Eclipse and Maven. Sometimes while using JUnit with Eclipse and Maven we have to face certain issues. And one of them is whenever we try to run the independent test case it will run fine and will not give any type of error. But when we run to try to compile the whole project, the same test will not compile at all. This is an annoying issue if someone does not know about the functionality of how Eclipse works with JUnit and Maven. JUnit in Action Since there is such no exception seen in file, but project compilation fails due to same file it is very frustrated for developer to figure out the issue. I am facing this issue and found a solution by googling around many forums. Problem : You have created a JUnit test case in the project and it is running fine, but fails to compile the whole project when try to build using Maven. Solution : Check that the test case you have created exist in the src/test/java folder and no...

RESTful Web Services - POST, PUT, GET, DELETE

Web services are very common these days as everything or most of the implementation is now API based. Every social network is providing API for fetching their data. Like if you take a case of TWITTER, it provides it's API to fetch different data related to user or for analytic. There are 2 types of web services namely: SOAP REST SOAP is based on WSDL and return data in XML format. But I will not talk about it here. I will be discussing about REST , an acronym for RE presentational S tate T ransfer methods. RESTful web services are very simple to learn and implement. They are basically stateless. It is based on HTTP URI and everything is implemented using URL. In this post I will explain about the four methods that are used with REST. POST PUT GET DELETE Let's dive deep into each of these methods of the REST. RESTful Java Web Services: Master Core REST Concepts and Create RESTful Web Services in Java POST It is used for creating a new entity. It is basically us...

Reset username for SVN in eclipse

Sometimes we want to change the username and password for the SVN access in Eclipse or Spring Tools Suite. But it does not asks for it. There is a very easy way of doing this. You can easily find out the solution on google :). I am writing here again to save to my memory. The solution is for Windows platform and tried and tested on Windows 7.  Here is the path where you need to delete one folder to do the same.  1. First close Eclipse/STS if your had open it. Some times without closing first it will not work.  2. Go to C:\Users\<username>\AppData\Roaming\Subversion\auth  3. Delete svn.simple folder  4. That's it. Now when you restart your IDE and go to SVN it will again ask you for credentials.  Note : AppData folder is hidden and not viewed by default. To make it visible follow below steps:  1. C:\Users\<username>  2. Go to menu Tools --> Folder Options --> View Tab --> Click Show hidden files, folders and drives under Hid...
