My JUnit Write Ups

I haven't written to my blog for a long time. There are times when you are busy and didn't get the time to work on the blogs.

I am writing for Java Code Geeks for some time and busy with one of the projects that I was building for a client.

Most of the blogs that I am writing was on JUnit. If you like this blogs do follow me on the Java Code Geeks at my author page.

Also, if possible do upvote my links on DZone.

I will be regularly writing on JUnit there. Hope you like those.

Getting height and width of image in Java

Yesterday I was working on something that requires manipulation of image for getting its properties. After searching over the internet I found a very intersting class on Java i.e ImageIO and BufferedImage class. These classes are good enough to manipulate images. there are many other claases also. But what I need i got it from these. I found many developers searching over internet for getting properties of image and there is no good small example for that. Thats why I thought why not creating a simple code to manipulate the image and help the developers. Here is the small code that helps to get the height and width of the image.

Struts 2 Hello World Example

I had seen many new deveopers struggling against struts2 hello world example. So I decided to write a small example. Below are the required libraries to run this example which are easily availabel struts2-core-2.1.8.1 xwork-core-2.1.6 commons-logging-1.0.4 commons-logging-api-1.1 freemarker-2.3.8 ognl-2.7.3 commons-fileupload-1.2 The structure of the applictaion which I am following is (Eclipse IDE) Struts2Demo |---src | |----org | | |----vinod | | | |----action | | | | |----HelloWorld।java |---struts.xml |---WebContent | |---jsp | |---HelloWorld।jsp |---index.jsp |---WEB-INF | |---lib | |---web.xml Struts 2 in Action It is true that different IDE's use different structure, but at last when war is build they follow same structure. Lets start...

Struts 2 Ajax drop down Example

Struts 2 has emerged as boon for developers. But the documentation available is very small. So I had decided to give a brief demonstration of the ajax used in struts 2.1.8.1 Libraries used: commons-beanutils-1.7.0.jar commons-fileupload-1.2.jar commons-logging-1.1.jar commons-logging-api-1.1.jar freemarker-2.3.8.jar struts2-core-2.1.8.1.jar struts2-dojo-plugin-2.1.8.1.jar xwork-core-2.1.6.jar In this example when u select from one drop down the other will populate accordingly. You can use it as it is or play with it. Enjoy !! index.jsp <%@ taglib prefix="s" uri="/struts-tags" %> <s:action name="ListingAction" executeResult="true"></s:action> listing.jsp <%@ taglib prefix="s" uri="/struts-tags"%> <%@ taglib prefix="sx" uri="/struts-dojo-tags"%> Listing detail.jsp <%@ taglib prefix="s" uri="/struts-tags"
