The JDBC-Driver is provided by the J2EE-Container.
So your Web-Applications doesn't really know which Version of a Driver is used.
If you Google you will find following advice:
java -cp ./db2jcc.jar com.ibm.db2.jcc.DB2Jcc -version
This is a way to display the used Version on Console. e.g. if you are a Server-Admin and you what to
know which driver version is installed on the system.
String[] errorSoon = {"-version"};
DB2Jcc.main(errorSoon);
The problem is, that DB2Jcc.main does not return a String which you ca pass to
the Servlet. So you want to know what DB2Jcc does.
The String you want to get generated by calling a static method qp.d();
import com.ibm.db2.jcc.am.qp;
qp.d() ;
Of course, this is only working if you use DB2.
So it is a good idea to Write a separate Servlet - in case that your
app uses a another JDBC-Driver (Another Vendor or Version of DB2)
that does not use this internal method.
