Hello guyz,
Im trying to use VAppli Emulator for Vodaphone which is built upon j2me,Whn i try to call a servlet using the code its showing me some Runtime Security Exception..
The code thro which im calling the servlet is as follows
public String NewDawnFirstServlet() throws IOException{
String itemData="";
HttpConnection http=null;
int d;
//String url="http://localhost:8888/NewDawn/FirstServlet"+"?UsrName="+nameTxt.getString()+"&PassWd="+passTxt.getString()+"&screenName=First";
String url="http://localhost:8888/NewDawn/FirstServletVAppli";
System.out.println("NewDawnServlet call Succeded");
try{
http = (HttpConnection)Connector.open(url);
http.setRequestMethod(HttpConnection.GET);
/*System.out.println(http.getResponseMessage());
InputStreamReader stream=new InputStreamReader(http.openInputStream(),"SJIS");
int returnCode=http.getResponseCode();
if(returnCode==HttpConnection.HTTP_OK){
while (true){
d=stream.read();
if (d==-1) break;
else itemData+=((char) d);
}
}*/
