Hi Luca,
sorry, I rewrite the message (wrongly formatted):
I have added a system.out in catch branch a s you can see below:
* OrientGraphFactory factory; factory =
new OrientGraphFactory("remote:localhost/HRG", "admin", "admin");*
* factory.setupPool(1, 10);
System.err.println("after pool setup"); _hrgGraph =
factory.getTx(); factory.close(); return true;
} catch (Exception e) { System.err.println(e.*
*getMessage()); return false; } finally {
System.err.println("finally"); }*
but I think that it is not Java the problem.
In fact, I have tried to shut down OrientDB server and running the project
and the exception correctly reported is:
*Cannot connect to any configured remote nodes: 127.0.0.1:2424
<http://127.0.0.1:2424>*
traced by the catch branch. Starting the OrientDB server and running the
project, there is no exception and after the execution the trace is only
"finally" and the catch branch is skipped and the execution goes in the
finally branch.
I want to know if the libraries included are right and if the code is
correct from your point of you.
Thanks for your help
Regards
Alessandro
