For what it is worth, I cut the code to a file and compiled it with javac
on my Windows PC.  It compiled with the javac that comes with both jdk
1.1.8 and jdk 1.3.  Other appends have correctly pointed out better ways to
write the code, but syntactly the code is correct.  I agree that it may be
something with VAJava.

One thing to try (a real long shot) is removing the "java.sql" before
DriverManager.  You import java.sql.* so you don't need to qualify
DriverManager.  Maybe you are confusing the compiler by qualifying it.
Another thing to try (another long shot) is don't import
com.ibm.as400.access.*.  If you use ONLY JDBC there are many cases where
you don't need to import the Toolbox classes because the driver manager
automatically find them.  Maybe VAJava finds the Toolbox Connection object
before it finds java.sql's, and is getting confused.

This gives me the same error. Is perhaps something wrong with my visual
age?
