Java.lang.NoSuchMethodError:java/io/File:

Question

hi all,
i have just a dbf file and no database server, can i still use the JDBC driver to make a connnection?
If yes, i put my dbf file in the Tomcat root directory and write con=DriverManager.getConnection("jdbc:DBF://localhost:8080/","","");
but it always returns an error
java.lang.NoSuchMethodError:java/io/File: method getCanonicalFile()Ljava/io/File ; not found
Anyone know what's wrong?
Below is the driver readme for the URL format:
URL format:
Direct Access:
jdbc:DBF:[/]/[DatabasePath]
For example: "jdbc:DBF:/." "jdbc:DBF:/../dbffiles"
Access by DBF Server: Skip it if you don't use RMI or JINI.
jdbc:DBF:[/][host][:port]/[DatabasePath]
Default host:localhost port:2129 DatabasePath:
For example: "jdbc:DBF://domain.com:3099/../dbffiles" if one DBFServer is run on the 3099 port of domain.com

We got a similar error the other day trying to grab the Meta-Data.
Once I took those lines out everything else worked fine. Ie our connection and loading code was fine.
It seems that not all methods are supported on all implementations of the jdbc/odbc drivers.
Our current issue has to do with having a lot of different databases, and not wanting to set up ODBC links to all of them (or wanting to find an easy way to do that).
