            e.printStackTrace();
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        } 
    }
}

for this java program to ececute your jsp

you have to add this line in your jsp page

<script>window.location.href="http://localhost:8080/OpenID/asd.html"</script>

where OpenId : Application Name
asd.html is your jsp page , the same jsp which you are calling from java program
