Subject [jira] Created: (DERBY-635) Client socket connection doesn't report real socket exception
Date Thu, 20 Oct 2005 20:48:49 GMT
Client socket connection doesn't report real socket exception
-------------------------------------------------------------

         Key: DERBY-635
         URL: http://issues.apache.org/jira/browse/DERBY-635
     Project: Derby
        Type: Improvement
  Components: Network Client  
    Versions: 10.1.1.0    
    Reporter: John C. Landers
    Priority: Minor


When opening a connection with a network url: jdbc:derby://localhost:4000/data
The netagent catchs the PrivilegedActionException but doesn't report the checked exception
in it.
Changing these lines
        try {
            socket_ = (java.net.Socket) java.security.AccessController.doPrivileged(new OpenSocketAction(server,
port));
        } catch (java.security.PrivilegedActionException e) {
            throw new DisconnectException(this,
                    e.getClass().getName() + " : Error opening socket to server " + server
+ " on port " + port + " with message : " + e.getMessage());
        }
To This returns the check exception information:
        try {
            socket_ = (java.net.Socket) java.security.AccessController.doPrivileged(new OpenSocketAction(server,
port));
        } catch (java.security.PrivilegedActionException e) {
            throw new DisconnectException(this,
                    e.getException().getClass().getName() + " : Error opening socket to server
" + server + " on port " + port + " with message : " + e.getException().getMessage());
        }


It currently reports messages like this:
Caused by: java.sql.SQLException: org.apache.derby.client.am.SqlException: java.security.PrivilegedActionException
: Error opening socket to server localhost on port 1527 with message : null

With this fix it reports:
org.apache.derby.client.am.DisconnectException: java.net.ConnectException : Error opening
socket to server localhost on port 1527 with message : Connection refused: connect
