Problems deploying an entity bean

[pjoisha]

Hi,
When I try to run ejbDeploy (via ANT build.xml)
I get an error to the affect that deploy tool
is not recognizing the "id" field in my VehiclePK
class as one of the attributes from VehicleBean
class. It somehow thinks the hashCode field
in VehiclePK class constitutes one of the
keys. In my VehiclePK class I see the "id"
field public and hashCode private. What am I
doing wrong? I have a feeling one my xmi files
is not telling the whole truth to the ejbDeloy.bat
Here's the transcript from ant .....
Buildfile: build.xml

Use Application Assembly Tool/AAT in WebSphere to verify your ejb jar first. And you may have to post your ejb-jar.xml here, maybe there is some wrong specification in it.

Hi Simon,
Appreciate your quick response.
Here's a little background on what I have been
trying to accomplish:
From a tutorial on websphere.com, I have
been trying to deploy some session + entity beans.
I have been successful in doing so using AAT
and Admin console. However, along with learning
the mechanics of xml and xmi descriptors, my
primary objective is to develop command line
scripts (using ANT) using the skeleton deployment
descriptors (all xml/xmi files) generated by AAT
and this where I'm failing. The build scripts
have worked all along and starts to fail
when I add this CMP Bean (my point here is that
there is nothing wrong with the script)

My Deployed_RentACar.ear (generated by AAT) works
just fine under WAS AEs4.0.1. I now take the
xml/xmi files (that was generated by AAT) and
copy them over to my build directory, build my
ejb jar with them and then run ejbdeploy (via
ANT) and this is when I get that error.
My ejb-jar.xml looks like this ...

<?xml version="1.0" encoding="UTF-8"?>

bad thing in the new XMI based deployment is it is not for human read. It is more suited for machine.
So xmi relies on the extra ID in the xml tag property to associate definitions, you have to be extremely careful.
I have no idea how to define xmi outside of AAT...

[pjoisha]

Thanks for your response.
I happened to resolve the problem. It had to do
with my PK class. It had a declaration to the
effect
private int hashCode = -1;
which I guess is not inline with the
specifications (atleast according to the
EJBDeploy.bat). Commenting this out lead
to a successful install via SEAppInstall.
I need to reread the EJB book to understand
this concept.
Thanks,
PJ

PS: As a side, yeah xmi by itself is pretty
complex without documentation (but that
article by Kyle Brown unravels some of the
mysteries). However, AAT also generates the
xml files which can be tinkered with a text
editor.
