I want to create tables in jsp when user run the jsp file first time,like we install wordpress,it can create table by itself.Can it use the sql file?
PS:just because my friend ask me to make a jsp website,in his computer of course,,but he know nothing about mysql,so I think I should let the program create database,like we install wordpress,we just enter username and password ,it can create everything for us.
This class will execute a script from a file: http://pastebin.com/f10584951
Use something like this inside a JSP page.
ScriptRunner scriptRunner = new ScripRunner(connection);
Reader reader = new FileReader("path to file");
scriptRunner.runScript(reader);
connection.commit();

I am writing a WordPress plugin.
In one program, I capture the WordPress user id and write it to a file in a custom database.
Another program connects to the custom database, retrieves multiple rows having the user id:
$connection = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);
$sql = "SELECT ...";
$prep = $connection->prepare($sql);
and tries to access the wordpress function after retrieving each record:
$user_info = get_userdata($user_id);
As soon as the get_userdata function is executed, the programs dies.
Do I need to connect to the wordpress database?
If so, how?
First of all, Why you have made database connection manually this way as you can able to use global variable "global $wpdb;" and then able to write query based on "$wpdb".
Second thing, you might declare that $user_id variable as global, so can access it globally in file or you should define in functions.php file and check for their availability.
Please let me know if any of this solution does not work for you with details.
The title of the question may be irrelevant to what I am trying to find out. My goal is to write a test that will
A) login to Hotmail
B) Delete the junk mail in my junk folder.
Design wise I have created 2 separate test classes. TestSignInPage1.class is only testing the user login part which is working and passed.
TestJunkFolderDelete.class will go to junk mail folder and do the deletion. I understand I simply can’t use the junk delete test on its own, a user 1st needs to login to the account so I called the TestSignInPage1 class in the junk folder.
#Test
public void testJunk(){
//The part below will get my login credential from TestSignPage class
TestSignInPage1 t= new TestSignInPage1();
t.testPage1();
//The following part will handle junk folder clean operation
WebDriver driver=br.openBrowser("firefox", "https://outlook.live.com/owa/?realm=hotmail.com&path=/mail/junkemail");
JunkMail jm= PageFactory.initElements(driver, JunkMail.class);
jm.doJunkClean();
Problem: Once the login part has been executed, the junk folder delete test opens up another new browser and again asks for login information.
Question: In professional world how would you tackle this (i.e.: you will have 1 test only, is there a way to keep the same session 1 browser) etc?
I've just created a Barcode Scanner app and have a database of barcode. I want to upload/sync this database to the company's server then another programmer can get and build website UI. Unfortunately, our server is not public (but it can connect internet through proxy), so I want to use Dropbox to do that. Could you please give me a useful sample code or tell me the best way to upload/sync database in this case? I am extremely grateful for your help!
Alright, assuming your database is a MySQL DB with a host environment that lets you run cron jobs, access your FTP, etc... here's a possible code snippet for you, I just had to do this myself with the Dropbox API, you can actually read the full post here for a walk-thru (Dropbox API and MySQL DB Dump/Upload
<?php
# Include the Dropbox SDK libraries
require_once __DIR__."/dropbox-sdk/lib/Dropbox/autoload.php";
use \Dropbox as dbx;
//your access token from the Dropbox App Panel
$accessToken = 'NOT-A-REAL-TOKEN-REPLACE-THIS-QM8jS0z1w1t-REPLACE-THIS-TOKEN';
//run the MySQL dump and zip;
// location of your temp directory
$tmpDir = "your_temp_dir";
// username for MySQL
$user = "DB_user";
// password for MySQL
$password = "DB_password";
// database name to backup
$dbName = "DB_name";
// hostname or IP where database resides
$dbHost = "your_hostname";
// the zip file will have this prefix
$prefix = "sql_db_";
// Create the database backup file
$sqlFile = $tmpDir.$prefix.date('Y_m_d_h:i:s').".sql";
$backupFilename = $prefix.date('Y_m_d_h:i:s').".tgz";
$backupFile = $tmpDir.$backupFilename;
$createBackup = "mysqldump -h ".$dbHost." -u ".$user." --password='".$password."' ".$dbName." --> ".$sqlFile;
//echo $createBackup;
$createZip = "tar cvzf $backupFile $sqlFile";
//echo $createZip;
exec($createBackup);
exec($createZip);
//now run the DBox app info and set the client; we are naming the app folder SQL_Backup but CHANGE THAT TO YOUR ACTUAL APP FOLDER NAME;
$appInfo = dbx\AppInfo::loadFromJsonFile(__DIR__."/config.json");
$dbxClient = new dbx\Client($accessToken, "SQL_Backup");
//now the main handling of the zipped file upload;
//this message will send in a system e-mail from your cron job (assuming you set up cron to email you);
echo("Uploading $backupFilename to Dropbox\n");
//this is the actual Dropbox upload method;
$f = fopen($backupFile, "rb");
$result = $dbxClient->uploadFile('/SQL_Backup/'.$backupFilename, dbx\WriteMode::force(), $f);
fclose($f);
// Delete the temporary files
unlink($sqlFile);
unlink($backupFile);
?>
You also need to make a config.json file like so:
{
"key": "YOUR_KEY_FROM_DROPBOX_APP_PANEL",
"secret": "YOUR_SECRET_FROM_DROPBOX_APP_PANEL"
}
You will need to create a new Dropbox app under your Dropbox account to get your key and secret, and to generate the auth code for your username, do that here when logged in: https://www.dropbox.com/developers/apps
You also need to download the Dropbox PHP SDK library to put on your server in the same folder as this PHP code above, find that here: https://www.dropbox.com/developers/core/sdks/php
Hope this helps; if you need more step-by-step or your developer does, go that link at the top for a full walk through.
i have a simple question. if i use play.db.ebean.Model to have my Model extend from Model, how can i save it into DB? more clearly: in Django, the database file is created and i save the object, it will be saved into db file and i dont do any sql statements for retrieving or saving objects.. how does this work in playframework?
lets say i have configured my database file in application.conf file like this:
db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:tcp://localhost/~/microblogdb"
db.default.user="sa"
db.default.password=""
now i have a database file somewhere in system.
now i have a Class User which extends Model as i stated above. now i want to save one User object into db. so i will do like this:
User user = new User();
user.username = "testusername";
user.fullname = "userfullname";
user.save();
what will happen after that save() call? can i now directly see my User object in database file?
appreciate any help!
many thanks
Yes it will, if you didn't do any mistakes.
Make sure that in application.conf you also UNcommented the line:
ebean.default="models.*"
Check sample applications in sample folder of the Play package you downloaded. For an example ComputerDatabase (not JPA version) to see the basics of working with Ebean.
What's more you can create constructor(s) in your model to simplify creating User model:
public User(String username, String fullname) {
this.username = username;
this.fullname = fullname;
}
And use it in controller as:
User user = new User("doniyor", "Doniyor The Great");
user.save();
I've read questions on Stack Overflow very similar to this question, but not quite the same.
Let's say that I had the following config.inc.php file included on every page of my website:
<?php
$site_name = 'Acme Inc.';
$authenticate_with_ldap = true;
$ldap_host = 'ldap.example.com';
$ldap_port = 389;
$ldap_rdn = 'ldap-user';
$ldap_password = 'ldap-pass';
$ldap_dn = 'ou=example,dc=example,dc=com';
$smtp_username = 'smtp-user';
$smtp_password = 'smtp-pass';
$recaptcha_publickey = 'my-recaptcha-publickey';
$recaptcha_privatekey = 'my-recaptcha-privatekey';
?>
Note: I have chosen to keep the website configuration in a file instead of the database because the information is used all over the website and it would be a lot more code and, I'm guessing, a lot more overhead to have to query the database for the same information all the time.
Now let's say that the website administrator is the type of person who would prefer to edit the above information using a CMS as opposed to going in and editing the file manually. My fear is that when the website administrator clicks the "Update" button and the PHP script gets to the file_put_contents function that overwrites the config.inc.php file, something could go wrong and either corrupt the file or make it unusable due to a syntax error or something.
Is this a reasonable concern? Should I tell the website administrator that he should just tough it out and edit the file manually? Should I store the information in the database instead? Or should I store the information in both places so that if the file gets messed up, it can be regenerated using the information in the database?
If you store that info in the DB as a single row of data, wouldn't it be cached anyway?
