The first thing to check in this situation is the JDBC URL that you are using. By default, this should be:
jdbc:easysoft://server_name:8031/odbc_data_source
Here, the Easysoft JDBC-ODBC Bridge client tries to connect through port 8031. If this is an invalid port number, the connection hangs. Edit the URL to contain a valid JDBC-ODBC Bridge server port number, such as 8831.
