If you upgrade to jConnect 4.5 or 5.5 from earlier versions, the following table shows which upgrade paths require you to make changes and recompile the source code.
Legend:
A Change CLASSPATH for new installation structure
B Recompile to use new jConnect 5.x driver
C Verify that the new driver is first in your CLASSPATH.
See below for additional details.

Change package imports from
import com.sybase.jdbc.*
to
import com.sybase.jdbcx.*;
Use new Sybase extentions APIs. See “Sybase extensions”.
Set JDBC_HOME to the top directory of the jConnect driver you installed. For example:
For jConnect 4.5:
JDBC_HOME=jConnect-4_5
For jConnect 5.5:
JDBC_HOME=<jConnect installation directory>
For more information on setting JDBC_HOME, see “Setting Environment Variables” in Chapter 1 of the jConnect for JDBC Installation Guide.

Change the source code where the driver is loaded from:
Class.forName("com.sybase.jdbc.SybDriver");
to
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
To verify that the new jConnect driver is first in your CLASSPATH, display your CLASSPATH and find the directory where you installed the new jConnect driver.
Verify that the classes for the new driver (in the classes/jconn2.jar for 5.x) appear in the CLASSPATH before the classes for any previously installed driver.
