awebproMemberI wrote the following basic servlet. Most of is MyElipse generated code. One the last line where it says,
“Class.forName(“sun.jdbc.odbc.JdbcOdbcDriver”);”, it gives me the following error,
“Unhandled exception type ClassNotFoundException”. It apparently cannot find the ‘Class’ class anywhere. I tried to do shift-ctrl-O, but it won’t find it either. Since this is very basic java sql, does anyone have any idea why it won’t find the ‘Class’ clas?*****************************************************************************

Haris PecoMemberawebro,
Class is from java.lang and it’s loaded default – you needn’t import – Do you sure that ClassNotFound is for Class ?
if yes, then you have jdk problem ? Check your server’s jdkBest
