java.sql.SQLNonTransientConnectionException: java.net.ConnectException :
Error connecting to server localhost on port 1527 with message Connection refused: connect.
I am using Netbeans.
If I go to the Services Tab and rightclick Java DB and start Server it works fine.
How can I do this programmaticly at Runtime. I just need whatever method will start the Java DB Server.
Have a look at how to use JavaDB with a desktop application. They describe how to start it programmatically there.
You need to start the NetworkServerControl additional documentation can be found here
NetworkServerControl server = new NetworkServerControl(InetAddress.getByName("localhost"), port);

Im trying to execute a jar file from linux.The jar contains java code for connecting to sql server. When I try to execute the jar, Im getting the below error
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host servername, port 1433 has failed. Error: "null. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
The connect properties file seems to have a valid username/password. I have checked the sql server configuration manager and the TCP/IP protocol is enabled. Im able to execute the same jar file in winodws and the sql server connection is established fine without any issues. Please let me know the steps I have to take to get this issue resolved.
Any help on this is much appreciated. Thanks
When I print the I.P. address of the system using InetAddress.getLocalHost(), I get user-VAIO/192.168.1.3 . Now, when I connect to derby using jdbc:derby://localhost:1527/mydatabase;create=true, it connects without any errors but when I connect the same using jdbc:derby://192.168.1.3:1527/mydatabase;create=true, it fails giving me the following exception:-
java.net.ConnectException : Error connecting to server 192.168.1.3 on port 1527 with message Connection refused: connect.
Any help will be appreciated.
When you start your Derby Network Server, you provide a value for the '-h' argument. You might not realize you are doing this, if you are using the packaged StartNetworkServer.bat file, but look inside the batch file, and you will see the -h argument there.
The batch file comes provided with the syntax '-h default' when you download Derby from the Apache website.
But you can change that, to say, for example, '-h 192.168.1.3', and then your Derby Network Server will accept connections that specify 'jdbc:derby://192.168.1.3/my/database'.
Note that if you want to accept such connections from other computers on the network, you will also have to adjust your Windows Firewall rules, as by default it will prevent such connections.
I downloaded Tomcat Deployer
so i could deploy remotely to my tomcat server, when insert all the correct details it ask for such as:
Manager URL
Username/Password
URL of sync App
when i try to deploy i keep getting this error:
Failed to deploy: com.caucho.hessian.client.HessianRuntimeException: java.net.ConnectException: Connection refused: connect
Projecct [HFJSe] deploy completed.
And nothing is deployed.
If there anything i need to do on my Tomcat server?
The error states that the target machine is refusing the connection, so you'll need to check the following information:
The URL is correct (I know you've stated it, but the URL should be in the format of http://{host}:{port}/TomcatHelper (from what I understand in the documentation)
That if there is a configuation file, that the port is configured appropriately
The target server has that port open to accepting connections
Your username and password is correct
If your "remote" server is on the same local machine, use your loopback address (i.e. localhost
