Have finally found the error. it was : i didnot say 'package foo;' in the java file. do try this.

java file : the class file should be in WEB-INF/classes/foo/

 
package foo;
 
public class ExampleBean{
private int member;
 
public int getMember(){
return member;
}
 
public void setMember(int mem){
member=mem;
}
}
 
 

jsp file : should be in applicationFolder

This is an example jsp page !!
<jsp:useBean id="ex1" class="foo.ExampleBean" />
<jsp:setProperty name="ex1" property="member" value="5"/>
<jsp:getProperty name="ex1" property="member"/>
 

its working only with packages. i'll find the reason soon, why its not working without using packages. please tell me if you find it.

[Bear Bibeault]

All classes must be in a package other than the default.

[Arul Jose]

to me the default was not working at all. it was working only with packages.

i tried without giving the package name in anything. it showed the 'class not found exception'

[Bear Bibeault]

Correct, if the class is not in a package, the container will be unable to load it. Package your classes.
