Which is the sybase driver(version) to be used in Weblogic 12c ? Where should I add the downloaded driver?

I am migrating my application from Weblogic 9 to 12c.

The connection pool - cvSybasepool created for my application is working fine on Web logic 9.
I had used com.sybase.jdbc.SybDriver to connect to Sybase database on Weblogic 9.

After replicating the connection pool(cvSybasepool) on Weblogic 12c, I get the following error:

I suspect the Sybase JDBC driver jar is missing on Web logic 12c.

Also, When the Sybase driver provided by Web logic server is used, I get the following error

FILogger.log(232) - java.sql.SQLException: [FMWGEN][Sybase JDBC Driver][Sybase]A USE DATABASE statement is not allowed in a procedure or trigger. at weblogic.jdbc.sybasebase.ddcn.b(Unknown Source) at weblogic.jdbc.sybasebase.ddcn.a(Unknown Source) at weblogic.jdbc.sybasebase.ddcm.b(Unknown Source) at weblogic.jdbc.sybasebase.ddcm.a(Unknown Source)

Which driver needs to be used to connect to Sybase DB on Weblogic 12c? Jconn2.jar/Jconn3.jar?
Which jar needs to be added to Weblogic server?
Where do I need to add the jar and what configuration has be done?

Solution

I finally resolved the issue.

I could not use the sybase driver(weblogic.jdbc.sybase.SybaseDriver) bundled with weblogic as it was not complaint with my SQL code

Below are steps I followed.

Downloaded & copied JDBC driver JAR - jConnect.jar to ${WL_HOME}/server/lib/
Updated the setDomainEnv.cmd script in my domain's bin directory, and prepended the JAR file to the PRE_CLASSPATH environment variable(If the newly added JDBC driver JAR is required in other domains, then edit the commEnv.cmd/sh script in WL_HOME/common/bin and prepend your JAR file to the WEBLOGIC_CLASSPATH environment variable.)
Restarted the server.
