I made a little project with java and a database. I tryed it on another computer and the executable jar works perfectly except for the methods that need to read or write in a database. If i start it from my IDE (NetBeans) it works fine if i connect to the database. How can i do? The exception that i get is this:
java.sql.SQLNonTransientConnectionException: java.net.ConnectException : Errore

Your jar is trying to to connect to the database on the computer that it is currently running on (localhost). When you move the jar to another computer, Derby is not running on the new computer (now localhost) and you get the connection error. Change the Derby hostname in your configuration or code to the name of a computer that is running Derby.
The Derby docs have a tutorial on using Derby in server mode here: http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#ns_lookat_code. It describes setting a protocol URL for the database:
protocol = "jdbc:derby://localhost:1527/";
"localhost" refers the current computer that the software is running on. Wherever you are defining this protocl URL, set localhost to the domain name of the computer the server is running on.
You'll also need to make sure that you have network connectivity between your client/jar computer and your database (Derby) server. You probably do if they are both on the same network.

Make sure service is running using SOAP,
if it's then try increasing the time
if still not working, try to change the port
Make sure the web service is running. You can use a tool such as SoapUI (free) to test SOAP web services.
I'm trying to run my java card client side but as soon as the code try to connect the port 9025 I get the folowing error message. After googling I found that the file jcclient.properties is the main responsable about the connection parameters.

I don't see it trying to connect if I'm running from the IDE. So is this some sort of oracle-based spying attempt? What gives?
I think it's trying to auto-detect a proxy somehow.
I was able to make this go away in the Java Control Panel. On the General tab, in the Network Settings... dialog, switch from Use browser settings to Direct connection.
(I couldn't find any proxy settings specified in either Firefox or IE, though.)
I followed this step for configuration http://jmeter.apache.org/usermanual/remote-test.html
The 2 machines are on same subnet.
They can ping each other
Windows firewall is turned off
When I execute remote start its give a "Connection refused" exception.

Check whether your RMI port on your other machine(s) is closed? jMeter uses 1099 by default.
Use cmd and type:
telnet [ip-address] 1099
You, of course, started the jMeter server on all machines, right?
this problem is resolve
my computer is connected to the internet and when i start jmeter-server its start on public ip.
my ip is 192.168.137.1 but some how its start on my public ip when i check on google with my public ip is same
i stop internet and start jmeter-serrver again its working
thanks
I have a java application that works perfectly when running from Netbeans 7.1 but it crashes if I use the build jar.
I've been investigating the problem and I've noticed that the application holds on calling DriverManager.getConnection().
I'm doing something like:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection("jdbc:sqlserver://127.0.0.1:2304;user=username;password=12345;database=databasename");
I've also tried jtds but it has the same result.
I'm running on Windows 7 Home Premium
SQL Server 2008 (localhost)
Netbeans 7.1 (application works fine when running from Netbeans)
Java Version 1.6

What could be causing this?
I had the same problem with the DriverManager.getConnection call just hanging indefinitely.
What solved the problem for me was going back to Java 6 Update 25. Update 29 seems to introduce a bug with the JDBC connection to SQL Server. I think Update 27 (or earlier) still work fine.
Maybe you're not setting your CLASSPATH to include the SQL Server driver when running the jar file, whereas Netbeans probably has it included for you already.
