You can find HttpSessionEvent inside javax.servlet.http. Go to Java api you can find all the classes. for more details for HttpSeesionEvent class
you can look :

You need the Servlet API (servlet-api.jar)

You need to look in: servlet-api.jar not in rt.jar

thanks again,

i downloded that servlet-api.jar and placed in right place

my code follows

import javax.servlet.http.*;

class one
{
public static void main (String args[])
{
HttpSessionEvent HSE = new HttpSessionEvent();
HSE.getSession();
}
}

Error :
one.java:7: cannot access HttpSessionEvent
bad class file: .\HttpSessionEvent.class
class file contains wrong class: javax.servlet.http.HttpSessionEvent
Please remove or make sure it appears in the correct subdirectory of the classpath.
HttpSessionEvent HSE = new HttpSessionEvent();

I am not sure what you are trying to do. There is no default constructor for HttpSessionEvent. You need to create HttpSession object and you need to pass this a parameter to HttpSessionEvent constrouctor.

In addition to previous post. Where did you get servlet-api.jar? It looks like all classes lost their directories.

If you download Tomcat, you can find servlet-api.jar in tomcat/common/lib.
There is a link to the Javadoc Servlet API in my signature.

If you like unofficial sources of servlet API, then you can get it as servlet.jar in TJWS distribution you can find in my signature.
 
I agree. Here's the link: http://aspose.com/file-tools
