can any one just tell me whether all the types of jdbc drivers are compatible with JAVA WEBSERVER 2.0.i have been sucessful in running a servlet and connecting toa database using type1 driver jdbc:odbc driver but not with other types.how to use the othser types of drivers basically the type4 driver JTurbo.

it's not so much the servlet api version you need to be concerned with; jdbc is an independent and shouldn't really have relevance in the servlet environment. i think (not sure) that you only need to worry about your jdk and jre versions; the JDBC classes of your driver may implement functionality that isn't supported by your JDK/JRE, but I think it's safe to say that as long as it's supported by jdk/jre 1.1.8 - jdk/jre 1.3, your jdbc code should compile just fine in a servlet.
