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:
-----------------------------------------------------
compile-ejb:

BUILD FAILED
C:\Middlegen-2.1-src\samples\build.xml:700: Compile failed; see the
compiler err or output for details.
------------------------------------------------------
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
