I have a problem when i use J2EE server connecting to SQL Server 7.0. I use the the Sequeline 5.1 (jdbc driver for sql server which i downloaded the evaluation product from www.mereant.com). I follow the instruction how to config default.properties but i still get error when i start J2EE server. Here is the error message

Binding DataSource, name = jdbc/Merant, url = jdbc/XAMerant

Here is what i config in default.properties file

jdbc.drivers=COM.cloudscape.core.RmiJdbcDriver:com.merant.sequelink.jdbc.SequeLinkDriver # JDBC URL Examples:
# Oracle thin driver:
# jdbc:oracle:thin:@<host>:<port>:<sid>
# Cloudscape RMI driver:
# jdbc:cloudscape:rmi:<database>;create=true
# Merant driver:
# jdbc:sequelink://<host>:<port>/[SQLServer];Database=<database>

jdbc20.datasources=jdbc/Merant|jdbc/XAMerant

xadatasource.0.jndiname=jdbc/XAMerant

Expecting reply soon
Thank you

hi,
 i think u didn't append the driver jar in the J2EE_CLASSPATH..i think better u can go for sun jdbc odbc driver...it is simple to configure and use..

Although the JDBC:ODBC driver is not as robust as straight JDBC drivers ( especially ones that are commercially available and supported), and sun themselves don't recommend it for anything other than evaulation/prototyping.
