Sounds promising. With REST, do you mean you would like the user to freely traverse the associations amongst objects, and the client having enough state to know exactly "where" in the network of domain objects it is?

I'm having trouble getting a sample seam-hibernate reverse eng to build. I followed the directions in the movie and everything works up to the point of compiling.

I get "Begin cannot be resolved to a type" and so on for every annotation.

What am I doing wrong?

I'm using Eclipse 3.2RC7 and the latest plug-ins from the nightly build as recommended. The plugin has a couple of UI differences, choices regarding EJB3 and Java5 syntax generation, which I have tried but it makes no difference.

I have built other Seam examples with no problems.

did you add the seam jars to the project ?

Yes, but you have to be on the right track.

OK, it turns out the the "Import:From File System" step as illustrated in the movie doesn't work. I had to use:

"Properties:Java Build Path:Libraries:Add External Jar"

for all of the libraries and the build errors (related to libraries) disappeared.

I have a new problem now, that has an easy workaround. The code generator is generating com.example.mydatabase as the package name but it is putting the files in src.com.example.mydatabase. So I can edit the package line in each file.

you should allow it to generate into the root directory since it genereates more than just src.

in a future version we will allow you to generate these things in more managble steps.

Maybe I missed the solution, but I saw where other people are having a similar problem and I didn't see the solution:


17:44:58,661 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
javax.faces.FacesException: Cannot get value for expression '#{rolleruserSelector.pageTitle}'


It Builds, it deploys, but doesn't run.

My problem with the Seam tool is just told, I get the error message:

I have no many-to-many mappings. The database structure is very simple for testing. Is there a possible solution for this problem?

try to use the latest version of jboss ejb3 jars (jobss-ejb3 latest download) instead of the jars in ejb3.deploy in the server is still the old version.

More info: it doesn't always cause an exception, but it never returns any query results. If I put % in all the fields or a * in all the fields then it doesn't cause an exception.

This is probably closer to the root cause (SQL Error: -227):

I'm still at it. I'm still stuck. I don't want to be a pain in the butt, but...

This is one of those situations where I'm learning several things at once and I appreciate that fact. It means I'm too ignorant (not informed/knowledgable) yet to even be able to ask the right questions.

I've learned a lot... I've learned that:

- this is cool stuff and I know its early in development so I'm not expecting too much
- there are several different versions of Eclipse, JBoss, Seam, Hibernate, JFC and that's a complex matrix if this stuff is version sensitive
- there are differences between the Seam samples and the code generated by the SeamReverseEng tool and I have not sorted that out completely
- I have a natural (and very strong) tendency to not want to go backwards, since I'd like to start contributing to these projects
- a lot about how JBoss and Seam are put together in the process, still have a long way to go here, but it is very interesting
- Eclipse and ant are not well integrated -- this is frustrating

Also, various others have had most of the same problems that I have and I've tried to gather that all up and apply it (but it is scattered all over the place) -- so far I'm still failing.

It sure would be nice if somebody had a perscription for getting this to work with the (more or less) latest versions of everything -- even bleeding edge is OK. I did go build 4.0.5CR1 of JBoss so just tell me which versions of the other stuff I should get/build and I'll go for it.

OK I got the latest (I built jboss-4.0.5.CR1 from CVS) and used the libraries from there. Got the search page showing up now.

But, it fails when I hit the Find button with:

These exceptions are usually not the cause of the problem itself. Try looking at the JBoss/Tomcat console window. At the end of the stack you will find the exception that caused everything.
Post'em here.

I made some progress.

After re-installing JBoss using the JEMS installer and Seam using a build from CVS I was able to run the tool and get the find and create pages served up.

My table has just 2 cols:

+----------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+--------------+------+-----+---------+-------+
| lastname | varchar(50) | NO | PRI | | |
| email | varchar(255) | YES | | NULL | |
