You can call a servlet from any java class. It simply a matter of generating a
http request. Try to read and use java.net.URL and java.net.URLConnection. If
your servlet is taking GET request, it is very easy to call it. Just create a
URL object by passing the url string ( test that url with a browser) and
urlobject.getStream() method. Make a convenient wrapper class object from
java.io package and start reading. If your servlet takes only post request,
here is the code :
public static Vector submitData(String u, Properties props, int type) {
Vector data = new Vector();
URL url = null;
String query = "";
Enumeration names = props.propertyNames();
while(names.hasMoreElements()) {
String name = (String) names.nextElement();
String value = props.getProperty(name);
query += name + "=" + URLEncoder.encode(value);
if(names.hasMoreElements()) {
query += "&";
}
}
// System.out.println(query);
try {
url = new URL(u);
URLConnection uc = url.openConnection();
uc.setDoOutput(true);
uc.setDoInput(true);
uc.setAllowUserInteraction(false);
DataOutputStream dos = new DataOutputStream(uc.getOutputStream());
// The POST line, the Accept line, and
// the content-type headers are sent by the URLConnection.
// We just need to send the date
dos.writeBytes(query);
dos.close();
// Read the response
// DataInputStream dis = new DataInputStream();
BufferedReader dis = new BufferedReader(new
InputStreamReader(uc.getInputStream()));
String nextline;
while((nextline = dis.readLine()) != null) {
data.addElement(nextline);
}
dis.close();
}catch(Exception ex) {
}
return data;
}
For better results for GET request use java.net.HttpURLConnection
