DBF TCP Server do not start |

Hi, I have created a java DBF TCP Server. When I was testing it in a local database running Windows OS it was working ok. But then when I tested it in a Linux OS Server, I got the following messages:
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which r
equires it.
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:1
59)

Do you have any idea of what is going on?

You can use -Djava.awt.headless=true.
>at com.hxtt.sql.admin.Admin.(Unknown Source)
com.hxtt.sql.admin.Admin is for GUI Server. For a console call, from Run HXTT DBFServer as Windows Service or Linux(Solaris) Daemon, you can also run directly com.hxtt.sql.admin.HxttService.

I tryed to use -Djava.awt.headless=true and got this message:
Exception in thread "main" java.awt.HeadlessException

at packageName.DBFServer.main(DBFServer.java:63)
The packageName.DBFServer.main(DBFServer.java:63) has the following code:
admin = new Admin();
where admin is an instance of com.hxtt.sql.admin.Admin
I'm still going to try a Linux Daemon, but I'd like to know what happened.
Thanks for the attention

Because com.hxtt.sql.admin.Admin is a GUI admin, and your Linux command line doesn't support GUI because X11 DISPLAY variable wasn't set.

I tryed a Linux Daemon following the instructions on the link you posted previously, but it's still not working. Do I have to implement the daemon interface in my main class? Do you any samples of classes that use a linux daemon or use the com.hxtt.sql.admin.HxttService directly?
Thanks again

The linux daemon didn't work out, so I started the com.hxtt.sql.admin.HxttService directly and got the following messages:
Load service setting from /[user_home directory]/urlconfig.properties
HXTT Service started
So I guess the service started ok, but when my application try to connect to the remote database, it shows the following exception:
java.sql.SQLException: Failed to connect to remote database: java.sql.SQLException: Failed to get response from remote server: java.net.ConnectException: Connection refused: connect at com.hxtt.global.SQLState.SQLException(Unknown Source) at com.hxtt.sql.remote.RemoteDriver.int(Unknown Source) at com.hxtt.sql.remote.RemoteDriver.connect(Unknown Source) at com.hxtt.global.SQLState.getConnection(Unknown Source) at com.hxtt.sql.HxttDriver.getRemoteAccessConnection(Unknown Source) at com.hxtt.sql.HxttDriver.connect(Unknown Source) at java.sql.DriverManager.getConnection(DriverManager.java:525) at java.sql.DriverManager.getConnection(DriverManager.java:193) at packageName.getDBFConnection(DbConnectionManager.java:72)
So what JDBC URL should I use to connect to my remote database, since jdbc:dbf://host:port/[DatabasePath] it's not working?
Thanks again for you attention

Load service setting from /[user_home directory]/urlconfig.properties ?
It should tell you which property file is used by the daemon, or you should assign a property file. Are you assigned?
What's you linux server?
We tested in a redhat 9 server and it worked well following the instructions.

My server is a RedHat 9, but it has some custom kernel modifications.
The message from the HXTT Service was:
Load service setting from /root/urlconfig.properties
HXTT Service started.
My doubt now is with the HXTT Service running, what JDBC URL should I use in my client application so it can connect to the server database.

I don't know if this was my only mistake, but the client had the DBF_JDBC30 v3.0 and the server had the DBF_JDBC30 v2.2. Once I used both with v3.0 the HxttService worked fine!
Thanks for the patience
