createBeanClassInstanceCommand == null

[skully]

I am trying out the rc2 with JBoss 3.2.3 using MS Sequel Server 2000. After I converted my EJB's to the pure CMP model as described in the wiki and from examples from the "released" modules, the createBeanClassInstanceCommand == null error shows up when the module is started and tries to use a findAll(). The modules worked before I converted them and the quotes module worked before I added the fileset attributes (include name="org/jboss/nukes/core/ejb/UserEJB.java"...) in the build.xml.

Not sure what is wrong and any help is appreciated.

Here is the stack trace for the quotes module, if you need anything else...

[julien1]

this seem to be a CMP bug, never seen before

[cookman]

In the latest nukes snapshot, the same problem exists in news module, I have to change the generated jbosscmp-jdbc.xml from

<post-table-create>
<sql-statement>CREATE UNIQUE name ON nukes_news_topics (name);</sql-statement>
</post-table-create>

to

<post-table-create>
<sql-statement>CREATE UNIQUE name ON nuke_news_topics (name);</sql-statement>
</post-table-create>

I don't know why:(

[julien1]

I have looked at my version and the statement is corrected, try to get it from the CVS, the snapshot may be lagging behind the CVS (I hope not)

[skully]

For some reason the only way to get the modules to work is to actually remove the fileset with the include UserEJB et. al. block from their build files. I'm not sure what limitations that will pose on the modules, but they seem to work fine for the moment.

I also cannot get the source from the cvs due to a company firewall or blocked port problem and my project isn't of dire importance to bother the help desk with it. I can try the cvs snapshot again and see if that is working, it should be updated by now right?

I appreciate your quick responses and the help you have provided. I would be lost without this forum. Thank you.
