I got a similar error message even when just trying to load the
driver (class):

Exception in thread "main" java.lang.NoClassDefFoundError:
javax/resource/ResourceException
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:130)
at TestFirebirdJDBC.main(TestFirebirdJDBC.java:9)

------------------------------------------------------

import java.sql.*;

public class TestFirebirdJDBC
{

public static void main(String pArgs[])
{

try
{
Class.forName("org.firebirdsql.jdbc.FBDriver");
System.out.println("Firebird driver loaded successfully.");
}
catch (ClassNotFoundException e)
{
System.out.println("Can\'t load the Firebird driver!!!.");
} // try

} // public static void main

} // public class TestFirebirdJDBC

------------------------------------------------------

My configuration is:
- Windows 2000, SP3
- Java: 1.4.0-01 (and 1.4.0)
- Firebird JCA-JDBC driver 1.0 Beta1

Driver location:
c:\java\j2re1.4.0_01\lib\ext\firebirdsql.jar

------------------------------------------------------

Btw, are there any new builds available? I checked out
sourceforge.net but honestly saying I don't like to setup a CVS/ANT
environment just to build the sources containing the latest fixes.

Thanks you
