Otherwise any insight on this matter would be appreciated. I took data from a form to create a object. In my servlet I created a new instance of said object and use setters to set the objects values.

Question: I know the answer might be easy but struggling to get this to work. I have the below code } $csv = array(); // Open File with error handler if (($file = fopen('./csv/file.csv', 'r')) === false) { throw new Exception('There was an error loading the CSV file.'); } else { while (($line = fgetcsv($file, 1000)) !== false) { $csv[] = $line;} fclose($file);} if (isset($_GET['names'])) { $name = $_GET['names']; $results = array(); foreach($csv as $curr) { $Data = explode(',',$curr['1']); if(in_array($names,$Data) $results[] = $curr; } } else { ...... Blah blah blah ?> So what im trying to do is parse the data from the url with get and search the csv array to find matching string in each key and array[1] (its a 2 column csv file), if the name…

Question: I had added export statements for Hcatalog in my .bashrc file which eventually messed up my .basrc file. Now even if I open bashrc file in my cmd and remove those two export statements, still I am not able to run any of the commands.
