Please put your code in Code block. Edit your post to do so.

P.S.:- Not related to the solution of your query but related to Naming Convention, why the name of the Class (Servlet) in small? It should always be capital as per the standards.

Hello

Check your servlet class name in web.xml and the class name in your servlet class





It would be better if you follow MVC architecture. Separate persistence logic from servlet

There is a lots of error in your code. Check it properly.

All classes used in servlets should be in a package - the reason being that the JVM looks for bare classes in the "current" directory - something you have no control over in the servlet environment.

hai..
It is not recommended to override the init(-) lifecycle method rather than you initialise your jdbc objects in init() method which is not life cycle and internally called by init(-).though you can use init(-) in your servlet program it is not recommended and also not industry standard..init() is not lifecycle method but is the convenience method given to programmer to place programmer choice initialization logics by overriding the iniit(-).
Servlet container doesn't call init() directly for instantaiation event.it is internally called by init(-).. if you verify the source code you can easily understand the various scenarios..

<html>
<body bgcolor=paleblue>
<center><br><br><br>
<form action= "http://locahost:8090/minipro/checcking" >
<pre>user id :<input type=text name=id size=20>

</html>


give the url patter of your servlet class.use relative url than using absolute url.. moreover please see that there are no spelling mistakes.. it is localhost not locahost.please also see that the deployment directory structure is correct before you run your applicaton.. your servlet program should reside in classes folder and html program inside web root folder parallel to WEB-INF. you get 404 status code when your deployment directory structure is wrong or when you give wrong url pattern at browser window.. please check it once.

try to change your for page as below:

<form action= "/checcking" >
<pre>user id :<input type=text name=id size=20>
</pre>
<input type=submit name=submit value=submit>

That will not work. The action must start with the context path preceding the servlet path.
