2012-04-27 17:18:09,931 JConnection.invoke Cannot work with a closed Connection

I'm using a hsqldb database in jonas webserver, and my source code looks like this :

DataSource dataSourceJndiName = (DataSource) context.lookup("jdbc_1");

        J2EEConnectionPool pool = new J2EEConnectionPool(dataSourceJndiName);

        TableQuery tq = new TableQuery("MESSAGETRACE", pool);

        SQLContainer container = new SQLContainer(tq);

        resultsTable.setContainerDataSource(container);

Any suggestions?

Thank you in advance,

Bonjour,

I just faced the same issue with the SimpleJDBCConnectionPool using MS SQL server.

Your post is 2 years old. Did you find a solution ?

Merci

I used a FreeformQuery instead of TableQuery and it worked.

Hi, I am new to Vaadin and stuck with the following exception. Can anyone please help with this?
Thanks.

Well it seems to be quite obvious: using the user root an the password YES wasn't right when trying to authenticate to localhost or you're missing a port.

@Marius Reinwald: Thank you for taking note of my problem. It is solved now.
The Mysql connector had wrong path.
