Re: UnsupportedClassVersionError using ScottKlement's JDBCR4

Thanks everyone - I really appreciate the thoughtful responses.

Justin nailed the problem. I simply found an older version of the driver, installed and walaa - It worked! (Well I at least got past this problem and quickly moved on to the next!)

Thanks again and Justin, if you are ever in the Cleveland area, your next cold one is on me.

Not sure which JDK(Classic or J9) Andy's using, but something worth
clarify here:
1) -Djava.version is not used anymore for J9 JDKs. It's ready only, the
way to choose J9 JDK is JAVA_HOME.
2) Jdk 70 is only available for J9 . No classic JDK 7.0 available on IBM
i.
3) If you want using jdk70 , you can reference here for details:

IIRC, jtds 1.3.1 requires a newer version of Java. Can you run jdk70?

Subject: UnsupportedClassVersionError using ScottKlement's JDBCR4

First - thank you Scott for your contribution of the JDBCR4 suite!

I am getting an UnsupportedClassVersionError at the JDBC_ConnProp (drv
=
new_Driver(drivname); specifically) similar to an earlier email chain.

However in my case, JAVA *VERSION confirms I am on 1.5.0 and I also set
an
Environmental Variable in a CL prior to running the RPG program like
this:

ADDENVVAR ENVVAR(QIBM_RPG_JAVA_PROPERTIES)

VALUE('-DJAVA.VERSION=1.5;-DJAVA.AWT.HEADLESS=TRUE;-DOS400.AWT.NATIVE=TRUE;')

The .jar file I am using is jdts-1.3.1.

Any ideas on where to start?

Thanks in advance.

Andy
