How To show a splash screen in a GUI based JAVA program @ startup

By -
Splash screens are essential things in todyas GUI softwares. We can use them to make our software attractive and show our details. This is how it's done.
First Create your splash screen as a image(eg-gif)
Then go to your netbeans or eclipse project folder of your GUI program, using Windows explorer or a similar software.
Find the file named manifest.mf and open it using a text editing software like notepad or gedit.
Add the following line to the end and save.
SplashScreen-Image: filename.gif
Now copy and paste the splash screen (filename.gif) to the folder called src
Then build your project using netbeans or eclipse and create a jar file.
When you open your software by double clicking the jar file splash screen can be seen.
This worked on me in netbeans.

So that result object varies according to the web service which is deployed. The solution was to inspect the service at deployment time and create a new parser class according to that in the service deployment time. It has to be noted that this parser had to be generated as a .class file and dynamically added to the classpath. So the result was to use a bytecode manupulation library. There are few bytecode manuplulation libraries available as ASM and JavaAssist . I used JavaAssist for this.

So downloading each one is a very difficult task because there are problems like versions don't match, some libraries are outdated, etc.etc. There is a easy method. After installing the plugin Netbeans will automatically add the Jasper Reports library to its library collection. But it is missing one important...
