Java program to connect to remote MySQL db (having ssh server running) -


i want develop java swing application. in which, mysql db stored on 1 pc. , software can access db anywhere. new type of jdbc connection. so, searching possible ways create such remote connection. got following possible solutions:

1) can host db on web. that's worked me. tried host db on freesqldatabase.com allows remote db connection.

2) heard ssh tunneling. topic new me. so, first created ssh server on pc having mysql db. so, pc running ssh server. tried putty software on client machine connect ssh server. , working. able give access client machine through ssh tunnel.

so remote connection working now. want execute jdbc connection client computer. connect ssh running computer having db.

i familiar db connection using ip address, like,

string url = "jdbc:mysql://server ip address/databasename";            class.forname ("com.mysql.jdbc.driver");            conn = drivermanager.getconnection (url,"username","password");

so please tell me, ssh connection in java programming? how can connect server(pc having ssh running , mysql db) client pc?

thanx in advance.

jsch looking for.

this library doing same thing have done, tunneling local machine remote machine. jsch start tunnelling , jdbc connect thru jsch setting.

this example here.

package com.journaldev.java.ssh  import java.sql.drivermanager; import java.sql.preparedstatement; import java.sql.resultset; import java.sql.sqlexception;  import com.jcraft.jsch.jsch; import com.jcraft.jsch.session; import java.sql.connection;   public class mysqlconnoverssh {      /**      * java program connect remote database through ssh using port forwarding      * @author pankaj@journaldev      * @throws sqlexception       */     public static void main(string[] args) throws sqlexception {          int lport=5656;         string rhost="secure.journaldev.com";         string host="secure.journaldev.com";         int rport=3306;         string user="sshuser";         string password="sshpassword";         string dbusername = "mysql";         string dbpassword = "mysql123";         string url = "jdbc:mysql://localhost:"+lport+"/mydb";         string drivername="com.mysql.jdbc.driver";         connection conn = null;         session session= null;         try{             //set stricthostkeychecking property no avoid unknownhostkey issue             java.util.properties config = new java.util.properties();              config.put("stricthostkeychecking", "no");             jsch jsch = new jsch();             session=jsch.getsession(user, host, 22);             session.setpassword(password);             session.setconfig(config);             session.connect();             system.out.println("connected");             int assinged_port=session.setportforwardingl(lport, rhost, rport);             system.out.println("localhost:"+assinged_port+" -> "+rhost+":"+rport);             system.out.println("port forwarded");              //mysql database connectivity             class.forname(drivername).newinstance();             conn = drivermanager.getconnection (url, dbusername, dbpassword);             system.out.println ("database connection established");             system.out.println("done");         }catch(exception e){             e.printstacktrace();         }finally{             if(conn != null && !conn.isclosed()){                 system.out.println("closing database connection");                 conn.close();             }             if(session !=null && session.isconnected()){                 system.out.println("closing ssh connection");                 session.disconnect();             }         }     }  }

im never done config local machine start tunneling remote server when machine up.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
