[Middlegen-user] Installation issue...

[Justin C. Beck]

Hi,

I am using JDK v.1.4.2.02, Ant v.1.6.0 and Middlegen v.2.1.

I am trying to go through the steps in the getting started section of
the website...

When I run ant in the <middlegen-home>\samples directory I get the
following error...

---------------------------------------------

C:\Middlegen-2.1-src\samples>ant
Buildfile: build.xml

init:

fail-if-no-xdoclet-1.2:

check-driver-present:

panic-if-driver-not-present:

middlegen:

BUILD FAILED
java.lang.UnsupportedClassVersionError: middlegen/MiddlegenTask
(Unsupported maj
or.minor version 49.0)

Total time: 2 seconds
C:\Middlegen-2.1-src\samples>

----------------------------------------------------

It's worth noting that I just uninstalled jdk v.1.5.0 and replaced it
with jdk v.1.4.2 as I was getting this error:

-----------------------------------------------------

------------------------------------------------------

I figured that there may be an incompatability issue between Middlegen
and JDK 1.5.0...

Anyway... I'm rather confused. Any help appreciated.

Regards,

Justin
