Seam generate-entities failing

[azavia]

Hi,

I'm trying to use the seam-gen tool, but am getting some errors.

When I go to generate entities from the database, i get the following:

C:\jboss-seam>seam generate-entities
Buildfile: C:\jboss-seam\seam-gen\build.xml

JBoss version is 4.0.5, Seam is whatever is the latest download.

Everything else has worked, like new-form, new-action, etc. I just am trying to get this to work.

Database is postgresql. I specified the jdbc url first as jdbc:postgresql:seam_test, then as jdbc:postgresql://localhost:5432/seam_test

Thanks,
Brandon

You can't reverse engineer tables that don't have primary keys. You should not have tables w/o primary keys anyway.

[azavia]

Hi,

It does have a primary key. The create table statement was:

CREATE TABLE users
(
 username character varying(50) NOT NULL,
 email character varying(255) NOT NULL,
 CONSTRAINT username PRIMARY KEY (username)
) WITHOUT OIDS;
ALTER TABLE users OWNER TO "Brandon";

[manuel.gentile]

Maybe there are some problems with Postgresql!!!
I have the same error switching to Mysql solve the problem!!!

[azavia]

Hmm, interesting. I do prefer Postgresql, so I'd like to know if there's some way to resolve the problem.

thanks for the replies.

By the way what is the new-action command of the seam -gen tool supposed to be for? All it seems to do is respond to a button click. Isn't there a command for just adding a new page? That'd be very useful. :)

[azavia]

OK, I'm closer to having it work now. :)

I switched to mysql for now, just to test how this works.

I create a table named users, generate the entities, and it works. But then, I go to the test application, click "Users List", and get this:

I have no idea why I'd get such an error.

[gavin.king]

Do you have other messages before that in the log?

[azavia]

I figured it out. It was reading an old datasource configuration I guess, and it was expecting a certain table that no longer existed.

It all works, now. :) Now just have to read the Seam reference and get more comfortable with all of this.

Thanks for the replies.

BTW Gavin you known why seamgen doesn't work with PostgreSQL ?

Thanks!

No idea. You should report problems like this to Hibernate Tools guys (ie. Max Andersen).

OK, some more problems.

I was trying a bit more complicated example.

I had some tabls like the following:

mysql>

so, i run seam generate-entities using this database, and a project I called blog.

It builds successfully, but I get some errors when I go to the project at http://localhost:8080/blog

The first noticeable thing is that when i go to create an article, or a user, etc, I get an error about requiring an ending s:button tag. When I looked at the template, for one of the tags, there was an s:button, but s:link was used to close it.

I don't know why is this happening. I'm guessing it is some bug. I figured this wasn't too complicated of an example to test on, but I don't know.

Use CR2 (released yesterday)

Hi,

Unfortunately, that did not resolve the issue:

Error - Error Parsing /ArticleEdit.xhtml: Error Traced[line: 135] The element type "s:button" must be terminated by the matching end-tag "</s:button>".

view/ArticleEdit.xhtml, lines 130-136:

<div class="actionButtons">
 <s:button id="addcomment" value="Add comment"
 view="/CommentEdit.xhtml" propagation="begin">
 <f:param name="articleId"
 value="#{articleHome.instance.id}"/>
 </s:link>
 </div>

Obviously this is easily resolved, but it is obviously a bug.

Further, I get this error when trying to create a comment:

I don't know if this is it, but in CommentEdit.xhtml, there is:

<h:column>
 <f:facet name="header">user username</f:facet>
 #{article.user.id}
 </h:column>

Is ID required for every table? It seems to be recognizing my primary key just fine everywhere else.

Thanks for the replies.

[gavin.king]

You are wrong. It is definitely fixed by CR2. Delete the generated code and regenerate using CR2.

[azavia]

Whoops, you're right.

OK, just a few things then.

I noticed that Seam assume syou're using the default configuration, and doesn't allow you to specify otherwise unless you do a mass search-replace.

Everything else is looking great. Only thing is that it'd be nice if the generator would detect auto-incrementing columns, and not create a field for those, since one is usually not going to want to manually enter a value for that.

Anyway, thanks for the help.
