I have a mysql database created on a raspberry pi, I want to access it through a java application running on a laptop in the same local network.
I tried connecting that same application with another database on another computer on the network and it worked. I don't know why it isn't working with the RPI.
i connect through the following command:
String URL = "jdbc:mysql://192.168.11.157/DB_name";
try {
connection = DriverManager.getConnection(URL, USER, PASSWORD);
} catch (SQLException e) {
e.printStackTrace();
}
However, an exception is thrown and ERROR: Unable to Connect to Database. is printed to the console.
Edit:
Knowing that:
* I can access the database through a local app running on the same raspberry pi (i used #local).
* Can Successfully ping & SSH with the raspberry pi, even run the program mentioned in the previous point through the SSH and it works fine.
The stack trace:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

I think the reason you can not access the remote mysql may be due to the remote access restriction in my.cnf
please check the line
bind-address: is set to 127.0.0.1
under this restriction, you can not connect remotely with that mysql server;
to solve this, you need to change this line to:
bind-address: 0.0.0.0
in addition you should specify the port for connection as below:
String URL = "jdbc:mysql://192.168.11.157:3306/DB_name";
because mysql will connect port 3306 in default.
wish my answer could help you!
You have to check the next things:
Is the database active? Does it respond to another application except yours?
Is the network connection OK (eg firewall)?
Check the connection strings (perhaps the port is necessairy but I am not sure).
I am not really familiar with the raspberry. It seems that it's using a linux operating system (correct me if I am wrong). In this post, instruction are given on how to disable firewall on the device. It says that the firewall is the usual iptables firewall used on linux systems. I find this iptables tutorial (based on ubuntu) very useful. Perhaps it would give you some guidance.
Hope I helped!
You may be able to ping the raspberry pi but I am not sure what the interface used is.
Why don't you use MySQL Ping and see if it is responding?
Else it must be a network issue. Get it resolved and then connect. No alternatives for this.
You can issue a light weight ping to your database server to check the connection availability.
Please read following discussion and articles:
Ping MySQL Server
Ping syntax and example
My answer to one of such Communication link failures.
Solved:
Go into the my.cnf file (sudo nano /etc/mysql/my.cnf) file and
look for "bind-address" and make it “bind-address = * “
Reload MySQL config (sudo service mysql reload)
Restart MySQL server (sudo service mysql restart)
The url "jdbc:mysql://localhost:3306/mydb".
You lost the port 3306.
you need to print the exception to the console ,rather than print a customer "error",If you do
as that ,you can't get the key of the problem

I have created a service that opens a lots of remote resources; for a lot, i mean over 200k / day, but i think that less than 1000 connections are opened at the same time. After i connect to the remote resource, i open an input stream to get the file content.
Sometimes i get the following exception

This service starts correctly, opening just a few ports for limited needs because it needs to offer some services. While it is running, i get the above exception, what may be the cause?
A port is already being used and you try to bind it again. Check in your application if your are not trying to use a port twice.
Probably, you're trying to open a port that is already open.
open the terminal an type telnet to see if that port is already open. ie.
telnet localhost 9889
Trying ::1...
telnet: connect to address ::1: Connection refused
if this command returns Connection refused, that means the port is free.
I have created a java application to connect to a MySQL database.
Once through the program install creator I created an .exe .
This executable runs, and the first form is login. When he tries to access the database to confirm the details of login gives this error.
java.lang.NullPointerException
Someone can help me solve this? The path is correct, because if run the .jar the application runs normally.
I apologize for the inconvenience.
Only have this to try explain better my question :S
I'm so sorry... I'm running a executable version from my java aplication.

You have an error in this class/line
jTMainMenu.java:786
Seems you tried to load a image in this point of your code, i don't know how you are generating a executable from your java code but this may be the source of the problem. Try to put this image outside of your executable/jar and use a relative path to load the image, like './my_image'.
You also have to take care if your user make a link to your executable, in this case a relative path can't resolve your problem. A simple way to solve this in java is get the source code location.
getClass().getProtectionDomain().getCodeSource().getLocation();
And use this location to find your image.
Please check the line number from the Stacktrace where you are getting the NullPointerException.
it is straight forward to find out the null pointer exception. Object is null or not initialize on which you are calling the method
try{
// add database connection statement here
}catch(Exception e){
e.printstacktrace();
}
// run the program from the command prompt.
// you can print the e.printstacktrace() on the popup as well to get the exception details
If you make a .jar, move that jar somewhere separate from the IDE (i.e. their classpaths), and start the jar, do you receive a NullPointerException?
This can be caused by resources, getResource, getResourceAsStreem, getBundle, as they are not case-sensitive in the Windows file system, but are case sensitive in a jar(and under Linux/MacOS).
(Also File cannot be used for jar resources.)
You might look in the jar with 7zip or so to inspect all paths.
I think it is not getting image icon in defined path
at javax.swing.ImageIcon.<init>(Unknown Source)
I have the following two guesses:
There is a problem with your path or classpath and loading the resource
The lines
at sensores.forms.jTMainMenu.initComponents(jTMainMenu.java:786)
at sensores.forms.jTMainMenu.(jTMainMenu.java:57)
indicate that something is initialized. Usually Swing/AWT uses multiple threads, so you might have a race condition here: The reference to the resource is handed to ImageIcon in your ìnitComponents method before another thread could set the value to something non-null. Try using proper synchronization/locking.

Thank you.
I've got such an error after Eclipse had been updated from 4.4 to 4.4.1. All plugins were lost, I reinstalled them, then the problem occurred.
I have tried:
Close-open Eclipse
Sign out - sign in into my proper Google account
Reinstall Google plugin
Wait for a few hours...
Nothing was helpful.
While my Eclipse 4.4.1 has an Internet connection.
The only working solution for me was to use command-line tool appcfg
I solved the issue by signing out of google (bottom right in eclipse) and signing back again.
I hope it helps some one ...
This should be account which you use to publish to GAE
I was just having that issue. If I leave a socket open on my laptop without it being plugged in the default power savings will kick in and the socket will be closed. If I leave it plugged in I do not have that issue.
I also had this issue, and restarting Eclipse solved the problem.
I want to profile a Java EE application runs on JBoss 4. I use Ubuntu . Java 1.5. JProfiler 8.0.1. Server is Jboss 4. Once I set the host as localhost and try to profile,(New Session -> Attach -> Attach to profile JVM(Local or remote) ) JProfiler says, "Could not connect to localhost:8849. Please make sure that the remote address is correct ". But in the terminal, it shows the JBoss starting and I can access the web applications as well. I want to trace all creating java Ojbects and their sizes. How can I solve this issue ?
EDIT: The error log file of JProfiler shows.

Probably JBoss is not profiled, i.e. the profiling agent is not loaded.
You have to use the integration wizard to modify the JBoss start script.
Invoke
Session->Integration wizards->New Server Integration
select JBoss 4.x and follow the steps in the wizard.
I am not able to connect with SQL server 2008 R2 using java. The same code is working with SQL server 2005.
I have tried to find out the port and ip for the sqlserver service and it is giving me
ip - 0.0.0.0 and port 1434
I tried to use the same connection string that works in SQL Server 2005, but it won't work for me in SQL Server 2008. Here is my connection string:
conn=DriverManager.getConnection(jdbc:sqlserver://127.0.0.1:1434:DatabaseNameconnect?autoReconnect=true,user, password);
This is the Error:

Any help ?
There are many possibilities for your problem:
Firewall
No TCP/IP connector
some services are not running
Try to connect with the SQL-management Studio to you database. If this works, try to connect with SQL-Authentification over TCP/IP.
update
Take a look at the Documentation at http://msdn.microsoft.com/en-en/library/ms143693(v=sql.90).aspx
One obvious problem is that SQL Server listens on port 1433, not 1434. I've already answered this question elsewhere, but I can't be sure if it's an exact match for your problem because you haven't told us what error message you get.
