Hi friends,
I'm implementing Session Handling in MIDP for this i've build application using following reference,
http://developers.sun.com/techtopics/mobility/midp/articles/sessions/ This code work fine for doGet method at server side .But as i want send large data i've change the doGet tp doPost .
With following changes at Client side:
void invokeServlet(
String url) throws IOException {
HttpConnection c = null;
InputStream is = null;
OutputStream os = null;
StringBuffer b = new StringBuffer();
TextBox t = null;
try {
c = (HttpConnection)Connector.open(url);
c.setRequestMethod(HttpConnection.POST);
c.setRequestProperty("IF-Modified-Since", "20 Jan 2001 16:19:14 GMT");
c.setRequestProperty("User-Agent","Profile/MIDP-1.0 Configuration/CLDC-1.0");
c.setRequestProperty("Content-Language", "en-CA");
os = c.openOutputStream();
String str = "name="+user;
byte postmsg[] = str.getBytes();
System.out.println("Length: "+str.getBytes());
for(int i=0;i<postmsg.length;i++) {
os.write(postmsg[i]);
}
// or you can easily do:
// os.write(("name="+user).getBytes());
os.flush();
is = c.openDataInputStream();
// sendRequest(url,hc);
if (mSessionIDCookie != null)
c.setRequestProperty("Cookie", mSessionIDCookie);
String cookie = c.getHeaderField("Set-Cookie");
System.out.println("cookie : "+cookie);
if (cookie != null) {
int semicolon = cookie.indexOf(';');
mSessionIDCookie = cookie.substring(0, semicolon);
System.out.println("mSessionIDCookie : "+mSessionIDCookie);
}
int ch;
while ((ch = is.read()) != -1) {
b.append((char) ch);
System.out.print((char)ch);
}
t = new TextBox("Second Servlet", b.toString(), 1024, 0);
t.addCommand(backCommand);
t.setCommandListener(this);
} finally {
if(is!= null) {
is.close();
}
if(os != null) {
os.close();
}
if(c != null) {
c.close();
}
}
display.setCurrent(t);
}
But that doesn't help me?
For doPost method it always created new session id at server side and at Client side it throws IOException ,how could i resolve this issue?
How could i resolve this issue?
