Sooo, I am stuck again...
Here is the server part:
And the client part (it is here where I get the NullPointExeption): http://pastebin.com/f6c413e52
I am getting:
The problem is somewhere here:
or
I'm n00b, so please help in a way I can understand xD
Here is the server part:
PHP:
<?php
$host = "localhost";
$user = "root";
$pass = "";
$db = "chat";
$connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!");
// select database
mysql_select_db($db) or die ("Unable to select database!");
function login($method_name, $params, $app_data)
{
$nick = $params[0];
$dexist = mysql_query("SELECT * FROM `users` WHERE `nick` = '$nick'");
$num = mysql_num_rows($dexist);
if($num != 0) {
return "Already logged in or nick already exist";
} else {
mysql_query("INSERT INTO `users` VALUES ('$nick')");
return "Logged in";
}
}
function delete($method_name, $params, $app_data)
{
$nick = $params[0];
$dexist = mysql_query("SELECT * FROM `users` WHERE `nick` = '$nick'");
$num = mysql_num_rows($dexist);
if($num == 0) {
return "does not exist";
} else {
mysql_query("DELETE FROM `users` WHERE `nick` = '$nick' LIMIT 1");
return "Deleted";
}
}
function users($method_name, $params, $app_data)
{
$dexist = mysql_query("SELECT * FROM `users`")or die(mysql_error());
$u = 0;
while($nick1 = mysql_fetch_array($dexist)){
$nicks[$u] = $nick1["nick"];
$u++;
}
return $nicks;
}
function chatadd($method_name, $params, $app_data)
{
$chat = $params[0];
mysql_query("INSERT INTO `chat` VALUES ('$chat')");
return "submitted";
}

// Now we print the response for the client to read.
print $response;

I am getting:
Server, result and nick is set before that file is run, so there is no probs with that.
The problem is somewhere here:
Code:
String[] nicks = (String[]) client.execute("users", params);
for(int i = 0; i < nicks.length;i++){
nicks1[i] = nicks[i];
}
Code:
for(int i = 0; i < nicks1.length;i++){
cGui.jTextPane2.setText(nicks1[i]);
}
