[wildfly-dev] Internal Server error

[Mester József]

Hello and Merry Christmas

I have a maven web application, which contains only REST services. This 
is a very basic application. The whole app created with Netbeans auto 
generate tools.
I have a Debian Wheezy server and when I deploy my war everything is 
good, but some hours later REST service is not respond, and I only got 
Internal Server Error.
I had to disable my application , after I have to disable Datasource, re 
enable datasource, and after that re deploy my program.

Log:

of 'wait_timeout'. You should consider either expiring and/or testing 
connection validity before use in your application, increasing the 
server configured values for client timeouts, or using the Connector/J 
connection property 'autoReconnect=true' to avoid this problem.

How can I set the timeout or the autoReconnect?

Thank you.
