hi, (I read the FAQ of firebirdsql and tested for common errors)
I am using firebirdsql-full.jar driver for jdk 1.4 when i try to
connect i get

java.lang.NoClassDefFoundError: java/sql/Savepoint
at
org.firebirdsql.jca.FBManagedConnection.getConnection(FBManagedConnectio
n.java:292)
at

at org.firebirdsql.jdbc.FBDriver.connect(FBDriver.java:218)

lder.java:69)

--------------------------what did i wrong?

my url is "jdbc:firebirdsql:localhost/3050://Users/bubi/test.gdb"
(for confirmance of the correctness of the url: if I try to connect
with the wrong password I get: org.firebirdsql.jdbc.FBSQLException:
Resource Exception. Your user name and password are not defined. Ask
your database administrator to set up a Firebird login.)
