I'm implementing Oracle Advanced Securities using OracleDataSource. The program that uses OracleDataSource.setConnectionProperties() compiles well in windows. But neither compiles nor runs in solaris machine. Even in solaris it works fine with web interface but not working with thread program. The classes12.jar with oracle 9i also doesn't contain this setConnectionProperties(). But It is the Oracle Properties Extension. Could anyone tell me which driver contains the setConnectionProperties()? I'm using the same driver in windows as well as in solaris.
