[Virtuoso-devel] Using a pool of connection with Virt_Jena

[Sempe P. <Phi...@at...>]

Hello,

While trying to use the Virt_Jena API to connect Virtuoso using JDBC3, I see that a new Connection is created for each instance of VirtGraph:

virtuoso.jena.driver.VirtGraph (virt_jena.jar):
public VirtGraph(String graphName, String _url, String user, String password) {
  [...]
  Class.forName("virtuoso.jdbc3.Driver");
  connection = DriverManager.getConnection (url, user, password);
  [...]
}

And in virtuoso.jdbc3.Driver (virtjdbc3.jar):
public Connection connect(String s, Properties properties) throws VirtuosoException {
  [...]
  return new VirtuosoConnection(s, host, Integer.parseInt(port), properties);
  [...]
}

Is there's any mean to use a Connection pool ? Or do I missed something ?

virtjdbc3.jar appears to implement PooledConnection but it seems not reachable with virt_jena ...

Thanks.
