I hope this is useful to some one.

remove generated code from ejbPostCreate method(s)

InsertReservationAction - perform method

add before return mapping....

Hi all,

OK I have come further and now I really want to find somebody who knows=
what to do!

The problem with AbstractReplicatedStore is due to the parameter in web=
.xml <distributable/>.
You just need to remove it. This problem will stop you from editing ent=
ities so it is not just cosmetic.

By fiddling with some parameters and adding the foreign keys to all the=
reservations jsp I can view anyexisting reservations properly - I just=
can't change them.
I always get a null pointer exception in viewReservationAction. (The co=
de is:
value =3D req.getAttribute(name).toString();
but neither req nor name is null I checked.)

Does anybody know what you need to do to get the edit/insert functions =
with foreign keys to work? I know the Struts generation does not work, =
but I am quite prepared to make the changes manually if somebody can te=
ll me what needs to be done. I have looked through the webs and bug lis=
ts but came up a blank.

Hi,
I have been trying to use JBoss 3.2.1 because it supports compound ke=
ys (unlike JBoss 3.0).
Everything seems to work except:
1. I keep getting the following error message in JBoss although it is n=
ot fatal I'm concerned it might be important!
ERROR [SubscribingInterceptor] could not get AbstractReplicatedStore.
2. Foreign keys do not appear in the forms - how do you set them? Any a=
ttempt to create a table entry with a foreign key fails with a null exc=
eption (of course since I haven't said what the foreign keys are). Do I=
have to do something to set up the foreign keys?
3. When I generated source using my own database I had to make two chan=
ges:
a. For database DATE fields I had to change new java.sql.Date to ja=
va.sql.Date.valueOf in several places.
b. I had to change java.math.BigDecimal to java.lang.Double in orde=
r to get the EJB QL to be accepted by JBOSS.
4. I had to fiddle with the dependencies in the build.xml in order to g=
enerate the source and then run just the compile & deploy targets. Is t=
here a nice way to do that?

(Still fairly new to the incredibly complex world of J2EE. Thanks for t=
he product for all the problems I have had it certainly gives me a head=
start. What I would like is for you to integrate into Eclipse/Lomboz s=
o that I can use a development tool for extending the starter applicati=
on we can build using Middlegen. You should be fairly compatible as Lom=
boz uses xdoclet. I have been importing the generated source - the bigg=
est issue I have is that Lomboz builds sometimes fall over and don't sa=
y why!)
