  private String firstName = "";
  private String lastName = "";

//First Name property
  public void setFirstName(String name)
  {
    firstName = name;
  }

  public String getFirstName()
  {
    return firstName;
  }

//Last Name Property
  public void setLastName(String name)

  public String getLastName()

      value="<%=last%>" />

<%-- Get bean properties --%>
<P>
<jsp:getProperty name="EmployeeBean" property="fullName" />
</P>

</BODY>
</HTML>

Put the Java class in a package.

JSP pages have problems finding classes in default package.
