RE: Java Version?

Hi,

We are running a 9406-270 and are stuck with V5R1M0 and JDK 1.3.0 is the
highest you can load on it. This is going to be a short term solution, 6
months to a year, until we upgrade to a new AS400. The calls will be coming
from an RPG program to grab data from a SQL server on our network. I have
used SK's JDBCR4 before with great success and didn't want to spend a lot of
time learning something new since I already have most of the code written in
previous programs. I guess I'll use something quick and easy, like Microsoft
Query, and then dump it onto the AS400 manually for now.


Thanks,

Yep, there were significant changes in 1.5, enough so that pre 1.5

JVM's

won't run programs compiled from 1.5 on.

If you must run Java on the AS/400, look for an older compatible

version of

JTOpen, which includes the JDBC driver. As James mentioned, you'll also
need to check the JDBC version provided by that version of JTOpen; later
capabilities won't be supported.

I think we went through this before, but IMO the better option, if

possible,

is to run Java and web/JEE servers on a separate PC or server using JTOpen
for access/cooperation with the AS/400. Then you're free from constraints
and can use the latest versions of everything.

Yeah, Java 1.3 is really really old. I don't even know the date it was

EOLed. I

know Java 1.4 was back in 2008, so it was probably at least 2 years before
that.

Also JDBC 4 only works with Java 6 and higher. I don't think you can get

that in

5.1 though.

Hi,



I am receiving the following Java error message on the AS400 when I
try to connect using SK's JDBCR4 JDBC_ConnProp



java.lang.UnsupportedClassVersionError:
net/sourceforge/jtds/jdbc/Driver



I am currently running JDK 1.3.0 on V5R1M0. Am I just hopelessly out
of date?
