I have made a Java class with Mybean name. I am making use of JSP to set attributes and get attributes. I am getting an error which I am not able to resolve.

From the JSP specification:

As of JSP 2.0, it is illegal to refer to any classes from the unnamed (a.k.a. default) package.

So your bean must have a package declaration:

package foo;
public class MyBean {}

The package must be reflected in the application structure; e.g:

WEB-INF/classes/foo/MyBean.class

The qualified name must be used in the tag:

<jsp:useBean id="bean1" class="foo.MyBean"/>
