Hi,

Try getting a URL connection to the servelt and send the request as

import java.net.URL; // New addition

import com.oreilly.servlet.HttpMessage; // A support class, shown later

private String getServlet() {

try {

// Construct a URL referring to the servlet

URL url = new URL(getCodeBase(), "/servlet/myServlet");

// Create a com.oreilly.servlet.HttpMessage to communicate with that URL

HttpMessage msg = new HttpMessage(url);

// Send a GET message to the servlet, with no query string

// Get the response as an InputStream

InputStream in = msg.sendGetMessage();

// Wrap the InputStream with a DataInputStream

DataInputStream result =

new DataInputStream(new BufferedInputStream(in));

// Read the first line of the response, which should be

// a string representation of the current time

String response = result.readLine();

// Close the InputStream

in.close();

// Return the retrieved time

return response;

}

catch (Exception e) {

// If there was a problem, print to System.out

// (typically the Java console) and return null

e.printStackTrace();

return null;

}

}

Uma

Hi Madu,

to send a http get or post to a servlet or other http resource, consider using Apache Jakarta’s HttpClient lib.

Have at look at the example programs, hot to use HttpClient lib here

Hi Madhu,

Declare the methods in the servlet as 'public'.Place both the java program(through which u want to call the servlet) and the servlet in the same package.Create an object of the servlet class in ur java program and write the logic.

Else u can import the package(containing the servlet) in the java program.

Hope this helps you.
