Hi,

after a update in the weka.jar since 2-3 hours i can't get
a database connection what i'm done multiple time in the past
and i'm getting crazy  :-) ?

Many Thanks, 
Christian



##### Without ODBC #############
i use the frst or second!
jdbcDriver=org.gjt.mm.mysql.Driver
jdbcDriver=com.mysql.jdbc.Driver


c:\dm\weka3.4>java -cp mysql-connector-java-3.0.11-stable-bin.jar -jar 
weka.jar
Connecting to jdbc:mysql://localhost/direct

Cannot find suitable driver

Doing the mysql-connector-java-3.0.11-stable-bin.jar in an extra
folder and setting the Classpath it wouldn't work, too?

## With ODBC #############

c:\dm\weka3.4>java  -jar weka.jar
Loaded driver: sun.jdbc.odbc.JdbcOdbcDriver
Connecting to jdbc:odbc:weka
GenericObjectEditor: Problem making backup object                                     \
                
java.io.NotSerializableException: sun.jdbc.odbc.JdbcOdbcConnection
Executing query: SELECT * from qtrainrun
Connecting to jdbc:odbc:weka

In the gui comes up:

Problem executing DB query SELECT from ?


########### My DatabaseUtils.props  for Mysql with ODBC ###############

# The comma-separated list of jdbc drivers to use

#jdbcURL=jdbc:mysql://localhost/direct
jdbcURL=jdbc:odbc:weka

...and the other configurations i'didn't change!
