import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import org.apache.http.HttpResponse;

import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;


    public class callURL {
    public static void main(String[] args) 
    {
        String url = "http://localhost:8080/OpenID/asd.html";
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        HttpResponse response;
        StringBuilder builder= new StringBuilder();
        try 
        {
            response = httpClient.execute(httpPost);
            BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
            char[] buf = new char[8000];
            int l = 0;
                while (l >= 0) 
                {
                    builder.append(buf, 0, l);
                    l = in.read(buf);
                }

        } 
        catch (ClientProtocolException e) 
        {
            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
