Hi Ramesh,
Whats the doubt. Yes it will create a bean if you just give the
beanName(which is actually class name). You check what are the other
mendatory attributes for creating a bean. type is optional I think.

Hi all,
sorry for this offtopic question but i have a major doubt in the
<jsp:useBean>
giving beanName will create an instance of the class or not. I know that if
you give classattribute, then you get a new instance.
If anyone can throw light on this , would appreciate it.
class="package.class" type="package.class"
Instantiates a Bean from a class, using the new keyword and the class
constructor, and gives the Bean the type you specify in type. The class you
specify in class must not be abstract and must have a public, no-argument
constructor. The package and class names you use with both class and type
are case sensitive.
The value of type can be the same as class, a superclass of class, or an
interface implemented by class.
beanName="{ package.class | <%= expression %> }" type="package.class"
Instantiates a Bean from either a class or a serialized template, using the
java.beans.Beans.instantiate method, and gives the Bean the type specified
in type. Beans.instantiate checks whether a name represents a class or a
serialized template. If the Bean is a serialized template,
Beans.instantiate reads the serialized form (with a name like
package.class.ser) using a class loader. For more information, see the
JavaBeans API Specification.
The value of beanName is either a package and class name or an Expression
<syntaxref10.fm4.html> that evaluates to a package and class name, and is
passed to Beans.instantiate. The value of type is a package and class name.
The value of type can be the same as beanName, a superclass of beanName, or
an interface implemented by beanName.
With both beanName and type, the package and class names are case
sensitive.
