Inside <jsp:useBean> you have wrote <%= link.callconst()%>

<body>

    <jsp:useBean id="link" class="com.Sshexample">

    <%= link.callconst()%>

    </jsp:useBean>

    </body>


Use this 

<body>

    <jsp:useBean id="link" class="com.Sshexample"></jsp:useBean>

     <%= link.callconst()%>
    </body>
