which version of Jboss server are you using. I believe you need to be on the rc release. Seam has not bee updated to work on the latest version of jboss.

as noted in other threads with the same error:
the seam code generation does not support composite-id's (yet)

Doh- I searched the forum up and down, but didn't think I was using composite-id's. (As an aside, I'm using JBoss 4.0.4 CR2, and Seam 1.0 beta2) Here's the tables I was originally trying to generate from:

CREATE TABLE iplabel
(
 ip inet,
 idns varchar(256),
 xdns varchar(256),
 sysname text
);
CREATE TABLE ipmap
(
 reference_ip inet,
 ip inet
);

I guess it doesn't like it when there's no primary key defined either (does it just try to make all columns into a composite-id in that case?) Any thoughts on how this will be handled (if at all) by the code generation tool? (There's unfortunately quite a few legacy schemas out there that weren't designed all that well- in this case it's looking like I'll be re-writing the schema anyhow... but you can't always do that)

So, then I created a few test tables:

CREATE TABLE users
(
 id bigserial NOT NULL,
 username text NOT NULL,
 "password" text NOT NULL,
 fname text,
 lname text,
 email text,
 CONSTRAINT users_id_pk PRIMARY KEY (id),
 CONSTRAINT username_unq UNIQUE (username)
);
CREATE TABLE groups
(
 id bigserial NOT NULL,
 name text,
 description text,
 CONSTRAINT groups_id_pk PRIMARY KEY (id)
);
CREATE TABLE users_groups
(
 user_id int8 NOT NULL,
 group_id int8 NOT NULL,
 CONSTRAINT fk_group_id FOREIGN KEY (group_id)
 REFERENCES groups (id)
 ON UPDATE NO ACTION ON DELETE CASCADE,
 CONSTRAINT fk_user_id FOREIGN KEY (user_id)
 REFERENCES users (id)
 ON UPDATE NO ACTION ON DELETE CASCADE,
 CONSTRAINT user_group_unq UNIQUE (user_id, group_id)
);

And sure enough, it generates fine when I take out the user_group table. I'm sure you've been asked this before, but I don't think I've seen a recent update- any thoughts on when composite-id's will be included in the generation tool? (Either way, it's a nice jump-start for applications that need to do a lot of CRUD ops..)

I was able to build and deploy the app fine, but when I click on any of the links (search or add new) I get exceptions- the one below happens when clicking on search:

javax.servlet.ServletException: Cannot get value for expression '#{usersFinder.example.id}'
 org.jboss.seam.servlet.SeamExceptionFilter.doFilter(SeamExceptionFilter.java:51)
 org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

Off to search the forums again...

Thanks for the help- and I'm looking forward to using Seam- it looks like it'll make life much easier than just Struts and Hibernate...

as written many times before ;) ....if you really badly want composite-id support then why don't you contribute a patch.

I still get that problem "isJNDIname" not available.
I am trying nightly.

Please help :
JBossIDE-200605041002-nightly-ALL.zip
HibernateTools-3.1.0.200605041002-nightly.zip
and follow the procedure.
and restart with eclipse -clean
