Hey there,
Suppose you have a Stateful bean called "PersonManager" that handles both the
CRUD and search features for the "Person" entity. I'm using Session scope. I
have the following in the "PersonManager"
| @DataModel
| List people;
|
| @DataModelSelection
| Person selectedPerso
Dude, you rock... I don't know a way to transfer that large a file. Perhaps
you could send it and leave out the Jar files?
Thank you, thank You!

I hope I'm not being too forward, but could you perhaps send me a WAR file that
works for you on Tomcat 5.5? (Perhaps a simple app that has a single table in
MySql.) My e-mail address is [EMAIL PROTECTED]
If I had a working MySql example on Tomcat 5.5, then I'm sure that I could
identify where
Looking through the log-file, I see this error:

It seems the entity manager is not getting inject into the right place. I
continue to get this error:

Thank you so much for your response. At least now I'm getting different error
messages. :-)
There seems to be some conflicts in the Seam documentation. Do you need a
"entity-manager-factory" node as well? In some places I've read where this
configuration is needed (even though it never work
BTW, I wasn't being sarcastic. I was ramming against the "null entityManager"
error for quite some time, and your recommended config line has definitely
pushed me closer to the finish line. Again, thank you.

Hey everyone,
I'm having trouble getting my Seam app to run on Tomcat; the entityManager is
not being injected into my Seam objects, most notably the EntityQuery objects.
[Note: This app works fine on JBoss, so this is a config issue.]
Here is my components.xml file:

I bought the book "JBoss Seam: Simplicity and Power beyond Java EE 5.0". I've
been following the instructions to deploy an app on Tomcat, and I still cannot
get it to work.
Here is the latest in my list of problems:
Per the instructions in the book, I added an additional datasource via a

Hey there,
The problem I've hit deploying a Seam app to Tomcat deals with the datasource.
Here is a sample of the error trail that I get:

| 16:27:52,098 FATAL [
I'm sorry that I can't help you with this problem. However, have you ever
gotten a MySql-backed Seam app to work on Tomcat 5.5? I've been trying to do
this for about 8 days now, and I'm uber-stuck.

Hey everyone,
If you create a simple MySql database and then use the seam command-line tool
to create a WAR using this database, then everything works fine on JBoss but
not on Tomcat. The WAR file assumes you are deploying to JBoss, not Tomcat.
So I've created an Ant target to deploy to Tomca
I need to be able to deploy Seam apps on Tomcat. I've setup the datasource,
but keep getting this stack trace. Can anyone help me decipher the following
errors? Many thanks! -Michael

The components.xml file is in the /web-inf directory in the war file. In fact,
I've added a context to Tomcat pointing to an exploded directory containing my
web app, so I can confirm that the components.xml file is in the right place.

Is this the line that does it?

As an aside, once I get this figured out I will post a deploy.tomcat ant target
that should work for the war apps created using the seam command line tool.

I am able to get the Seam examples to run on Tomcat with no problem. Where I
run into trouble is when I do this:
1. Create a new ear application using the seam gen script
[The application runs against MySql.]
2. Generate the entities for the existing tables.
3. Add a new target to the build.
If my understanding is correct, the mc-conf.jar file consists of the files int
the jboss-seam-1.2.0/embedded-ejb/conf directory. This is shared across all
Seam example applications. If this is the case, then shouldn't all examples be
EJB3 enabled?
I did compare the contents of my mc-conf.jar

My ongoing saga to get my app running in Tomcat continues. I did a
