Solution :

          While installing JDK7 java derby will also installed and configured. But i explicitly configure different version java derby in class path. That's why the exception thrown. When i deleted class path which i configure explicitly its working fine.

I hope you know all posting more variety of hot topics. Now i came up with an idea to share my technical experience with you all. So posting every challenge in separate post is getting difficult. Now i shared one document which i will update frequently that document. Please click the link below.

java parse error web.xml in tomcat

Java parse error web.xml in tomcat

Hi Guys,

Here i want to share some experience about basic error which we will get frequently.....
I have created one web application using servlet and jsp. And i exported that project into war file and i deployed in tomcat 6.0. the application is not deploying and when i try to run from browser its showing "requested resource not found".... i dont know what thats the problem. i cant figure it out.... after trial and error method, i just came to know i created that project in Servlet3.0 version. so Tomcat 6.0 is not supporting that... thats why i got that error. after i changed into servlet 2.3 version its worked fine.

Jquery Tutorial 2

In this post we are going to see how to eliminate particular tag lies under parent tag.

for example if you are having below exmaple :

<ul>
    <li>
    <li>
    <li>
    < id='eliminate li>
<ul>

$("#lis").not("#eliminate").css("background-color","blue");

If you run above code, background color will change all li tags other than eliminate id li tag... so this is very useful for creating tabs in any application mouse over offect of menus....
