Hi Dan
Thanks a lot. Now the jdo project works.

The newest JDO enhancer plugin in Eclipse requires asm 4.0,while isis
provides 3.3.1. To fix the problem I have remove asm exclusion in =
pom.xml of
project quickstart-objstore-dom.

            <exclusions>
				<exclusion>
					<groupId>org.ow2.asm</groupId>
					<artifactId>asm</artifactId>
				</exclusion>
            </exclusions>

=D6=F7=CC=E2: Re: quickstart jdo exception

Hi Alain,

JDO requires that the pojos are "enhanced", that is, they go through a
post-compile process which injects additional bytecode into them.  =
There's
some good detail about this for JDO in general [1] and for DataNucleus =
(the
JDO implementation that we are using) in particular [2].

If you just build the code using Maven, then the code should be enhanced
using the maven plugin we have configured.  But if you are running from
Eclipse (or any other IDE), then you need to add in the appropriate JDO
enhancer plugin to your IDE... see  [3], [4], [5]

HTH
Dan
