Rauf,
Excuse me, but I don't understand. The error message that
Michael has posted states that the JVM cannot find the
"java.sql.Savepoint" class. What has this to do with the
connection URL that Michael is using?
[In any case, he said it works in JDeveloper]
According to the java documentation (javadoc) for J2SE
version 1.4.1, the "Savepoint" class is new (since version
1.4). Hence my guess is that Michael is using a JDBC driver
(or JRE) that is not compliant with version 1.4
Since Michael has provided a miniscule amount of information
regarding his environment, I will not hazard a guess as to
how he can resolve his problem.
[Hopefully, he should be able to figure it out for himself
from here :-]
Good Luck (to all of you),
Avi.
