Hi Jose,
I have something like this. As you can see, I only close the resources
on error, I think because I had a similar problem like you. You should
also check the Server if it crashed, from time to time it's happening
and you have to restart it. I hope it helps.
Jbase jB = null;
Jconnection jC = null;
Logger log = LoggerFactory.getLog(Main.class.getName());
try {
String host = Props.inst().getHost();
log.info("JBase host: " + host);
if (host.length() == 0) {
jB = new Jbase();
} else {
jB = new Jbase(host);
}
jC = jB.connect();
Jedi f1 = jC.open("F.GBI.EXP");
// Create a select list
ArrayList metaList = new ArrayList();
JdynArray rec = f1.read("T.T");
int apps = rec.scalar(2);
f1.close();
log.info("Application finished");
System.exit(0);
} catch (Exception e) {
log.error("Exception in Main: " + e.getMessage());
try {
if (jC != null) {
jC.disconnect();
}
if (jB != null) {
jB.terminate();
}
} catch (Exception e1) {
}
System.exit(2);
}
