Re: JDBC Problems

Hmmm... I THINK that in this particular case, a Connection class that
is defined in the UNNAMED package would probably cause the
error you're seeing.

Why?
1) java.sql.DriverManager.getConnection() will ALWAYS return a
java.sql.Connection object.

2) Since you've imported java.sql.* in your source, an
Connection declaration that is not package qualified you shouldn't
need a cast. Instead, your Connection object reference will ALWAYS:
A) be a java.sql.Connection, the only Connection class declared or imported
  OR
B) If you've got another Connection class in a different package, you will
get an ambiguous class reference error. If the other Connection
class is in the unnamed package you could get this error.

Did you define or can you find another definition for Connection
in the VA repository? (probably the unnamed package).
That class is causing you problems.
Fully qualify the Connection object as a java.sql.Connection object
or get rid of the other Connection class.

Duh!... as he hits himself for not reading...Try

 conn = (Connection) java.sql.DriverManager.getConnection
("jdbc:as400://KITS01");

and do the cast explicitly.  You are getting a compiler error correct?  Not
a run time exception?

Duncan

When I do the try (as in this email)
I get the same error: cannot convert from java.sql.Connection to
Connection.
I use Visual Age for Java 1.1
