What does your bean look like?  Firstly, I'm assuming it has "package 
my_classes_folder" at the top of it.  Secondly, the main reason I find those 
errors are the lack of a null argument constructor.  To use that useBean tag 
the way you are, you should have something like:

package my_classes_folder;

public class my_class_file
{
	public my_class_file() { }	
}

You might also have other things, I'm assuming you do, but that is the bare 
minimum.  However, you're not at all following conventions.  The above should 
be

package myPackage;

public class MyClass
{
	public MyClass() { }
}

which would have the following useBean tag:

<jsp:useBean id="cs" class="myPackage.MyClass" scope="request" />

DOes that make sense?

Thanks Dim,
  Yes there is
 package myPackage, also I have a public constructor as you mentioned .

package myPackage;
public class MyClass
{
	public MyClass() { }
}

and I use the bean as:

<jsp:useBean id="cs" class="myPackage.MyClass" scope="request"/>
<jsp:setProperty name="ps" property="*"/>

then i get the same error saying:
javax.servlet.ServletException:  Cannot create bean of class
myPackage.MyClass

What else could be wrong? Please help me out.. I am really bugged with this
error.

Thanks,
Suresh.
