[JBoss Seam] - seam-gen 'generate-entities' generates invalid code for tabl
by voreichel
Using seam-gen 'generate-entities' to generate a CRUD application from an existing PostgreSQL database does not generate working code.
I have the follwing two tables in my database:
Table t_user
| CREATE TABLE t_user
| (
| email character varying(255) NOT NULL,
| firstname character varying(255),
| lastname character varying(255),
| loginname character varying(255),
| "password" character varying(255),
| joined timestamp without time zone,
| CONSTRAINT t_user_pkey PRIMARY KEY (email)
| )
|
and a second table t_user_roles
| CREATE TABLE t_user_roles
| (
| t_user_email character varying(255) NOT NULL,
| element integer,
| CONSTRAINT fk8fc22a14c7001400 FOREIGN KEY (t_user_email)
| REFERENCES t_user (email) MATCH SIMPLE
| ON UPDATE NO ACTION ON DELETE NO ACTION
| )
|
element encodes which role a user is in.
When I run seam generate-entities I get no errors or warnings

Then I tried to open the generated webapp in a browser:
[img]http://www.seamguru.com/jbossforum/img/seamgenDBbug.jpg[/img]
[urlhttp://www.seamguru.com/jbossforum/img/seamgenDBbug.jpg[/url]
The error message tells me that class 'com.seamguru.seamquizadmin.TUserList' does not have a property 'tUser'.
The generated class TUserList defines a member tUser and a getter (getTUser). When I change the getter to gettUser. Please note the lowercase 't' in TUser. I get one step further.
Now I get a similar error for class TUserRoleList. Making similar change fixes this problem too.
Now the home screen of the application is rendered correctly. But selecting 'TUserRolesList' from the menu on the top of the page gives a similar error message as the the two before. Now property 'tUserEmail' cannot be found.
See [img]http://www.seamguru.com/jbossforum/img/seamDBBug2.png[/img]
See http://www.seamguru.com/jbossforum/img/seamDBBug2.png
My questions are:
Has anyone else seen this error?
Why does the error message complain about 'tUserEmail' / 'tUser' as far as I can see 'tUser' / 'tUserEmail' is not used in the XHTML pages?
Any response welcome!

I'm afraid that the details of what happens is mostly gory details... :)

The reference guide (http://docs.jboss.com/jbportal/v2.6.2/referenceGuide/html/) might contain the information that you need. Without context of what you're trying to achieve, it's difficult to answer your query. Plus, an explanation of Portal internals are outside of the scope of this forum. One could make a point that such an overview should be more prominent in the documentation and, if you feel strongly about it, please open a JIRA task for it. Ultimately, though, the source is the best documentation for the internal behavior of Portal. If you need more help figuring things out, you might want to consider buying consulting and/or support from us...

[Clustering/JBoss] - SFSB failover not working as expected
by chrismeadows
Hi there,
I'm testing two JBoss 4.2.2 GA nodes in a cluster using the 'all' config. The nodes cluster together fine. I then run a multithreaded client to start up 200 or so SFSBs that cycle through a number of states. The client requests are are load balanced in the cluster as expected.
However, when I test failover by killing one of the nodes mid test, I get various exceptions such as
javax.ejb.NoSuchEJBException, Could not find stateful bean: 4ss55r-gaev0q-f901ig99-1-f901ok6j-5w (bean was marked as removed)
and
javax.naming.NamingException, Could not dereference object
If I catch the exceptions and retry the client requests, then the SFSB state is sorted out and the results are as they should be
I might have missed something here, but I was expecting the client side interceptors to reroute client requests automatically on cluster member failure, i.e. I shouldn't have to programmatically catch the exceptions and retry.
I'm using HA-JNDI as follows
| jndiProps.put("java.naming.provider.url", "jnp://foo.zub.com:1100,jnp://bar.zub.com:1100");
| jndiProps.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
| jndiProps.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
|
and I've added retry interceptors as per section 16.3.1.1 of the JBoss 4 manual.
Did I miss something? Or have I misunderstood how JBoss failover is dealt with from the client?
Any insight/clarification gratefully received,
Regards,
Chris
