import java.sql.*;

try { String driverClassName = "com.ibm.db2.jcc.DB2Driver"; System.out.println (); System.out.println ( "Loading DB2 JDBC Driver: " + driverClassName ); Class.forName ( driverClassName );

}
catch (Exception e)
{
System.out.println(e.toString());
}
}
}
While running this code
getting this error :
Failure in loading native library db2jcct2zos4_64, java.lang.UnsatisfiedLinkError: db2jcct2zos4_64

We are using IBM ZD&T machine and all the software got installed during installation. We have not installed any software or configured anything of our own.
on executing System.out.println(System.getProperty("java.library.path")); we are getting following list of paths:

Just spitballing here, it looks like this library is not found db2jcct2zos4_64 in the path libraries.
I would do a OMVS find command to see where that library is, and then add that library to the path.
TSO OMVS
| Code: |
| $ find / -name db2jcct2zos4_64 -depth |
