quickstart jdo exception
Hi
I have exported the quickstart project yestoday. And I want to find how the
jdo works. There is exception when I run the quickstart-viewer-wicket
project to add a new ToDoItem. The exception is:

Re: 答复: quickstart jdo exception

Hi Alain,
Yes, I came across this clash of versions for asm also, which is why I
*added* the exclusion in quickstart-dom/pom.xml:
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-enhancer</artifactId>
<exclusions>
<exclusion>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
</exclusion>
</exclusions>
</dependency>
>From your mail, it sounds like you had to remove that exclusion to get
things working? I'm a bit confused by that... didn't it cause the clash in
asm versions?
In my tests the above pom.xml seems to work fine (have tested this on a
newly built machine that just has mvn and Java installed, nothing else).
Any insights your end welcome.
Dan

答复: quickstart jdo exception
Posted by 张峰昌 <al...@gmail.com>.
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>

主题: 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]

Re: quickstart jdo exception
Posted by Dan Haywood <da...@haywood-associates.co.uk>.
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]
