In the User entity bean an e-mail address is validated using @Email. It works
fine, but the user should also be allowed not to enter anything in this field.
The field is not annotated with @NotNull and the default in the database is
null for this field. However, Seam wants a value there.
Hi Tynor,
Seam 1.2.0GA and JBoss-4.2.0.
I downloaded hibernate validator 3.0.0 and will now use that.
Thanks very much.

I don't know if I have a Seam Managed Persistence Context in my components.xml.
I'm mailing this from work. But I at last did get s:selectItems to work.
What did the trick was that every @entity that is used as a source for
s:selectItems must implement a boolean equals(Object obj) and an int

objects backing them. They should be outjected from one of your action beans
(session beans). Create a @Factory method in the relevant bean where you
outject them to make sure they don't have null values. When you

Any idea how to implement a pop-up window just big enough for an image? I

This is how I've done the pop-up, and it works:

Just download the version you want and unpack it. Then use the jars
(jboss-seam.jar, etc.) in its root directory in your application instead of
your older seam version jars. If you need any of the jars in the /lib
directory on your classpath, use them instead of others with the same name you
Got it. formdata should be form-data.

Hi Markus,
Yes, it's there. Only, I called it Seam Filter and not Seam Multipart Filter.
I changed the name, moved it up in web.xml - no luck.
A simple text input get its value propagated to the session bean. The file
upload input is totally invisible to the application.
As far as I'm
s:fileUpload doesn't work for me. Here is what I have: Seam 1.2.1.GA,
JBoss-4.2.0. I use xhtml, not jsp's.
In the ear I have jboss-seam.jar and in WEB-INF/lib jboss-seam-ui.jar,
jboss-seam-debug.jar and jsf-facelets.jar.
This is what is in web.xml:

The following html is generated:
option value=0admin/option
| option value=1manager/option
| option value=2user/option
It should be this:
option value=adminadmin/option
| option value=managermanager/option
| option value=useruser/option
This comes from the Role class which has an @Id
So far nothing helps. The problem only arises when I perform an action from a
xhtml page containing #{s:hasRole(... When I log in from another page and then
request the offending page via the browser address field, everything is fine.
The links are correctly rendered according to the role of

Hi Shane,
I downloaded 1.3.0 and tried. That caused a whole new universe of problems. If
I remove jboss-seam.jar from the ear and copy it to

I have a custom util class called LessonView. It looks like this:
public class LessonView{
| private String subject;
| private int year, count;
|
| public LessonView(){}

| public LessonView(String subject, int year, int count){
| sets the variables via setters
| }

Hi Dornus,
There are two solutions I can think of. The first side-steps an EJB query.
One of class A's attributes will be a collections of some sort of class B.
Simply get an instance of class A by primary key, get an instance of the
collection of Bs and do a bees.size().
The second is to

Thanks for your answer. Clear, unambiguous and easy to implement. I like them
that way. ;-)

Hi Peter,
Here is the solution to the java time problem in Linux. I added one line to my
JBoss start-up script and that does it. Here is the whole start-up script:

There is a utility class (UsernamePasswordHandler) in the war container. It is
used for log-ins. When instantiated from any class in the war container,
things are fine.
However, when the only class in the jar container that needs it tries to
instantiate it, a java.lang.NoClassDefFoundError
Thanks for the replies. I thought about three fields because there are so many
ways to enter dates; 2006-12-22, 22/12/06, 22-12-2006, etc. Of course, with
the examples given one can find the right date in some instances. 6-9-06 is
harder to figure out. Each field clearly labeled as day,
I'm new to Seam. After reading some of the documentation and looking at the
examples I'm left with one question. Searches of the forum provide no answer.
One html form field in Seam seems to map to one attribute in a POJO which in
turn seems to map to one field in a database. Now say I want
Hi Kingcu,
Which class is not found?
All I can recommend is a step by step drill-down to find the problem.
1)Get the name of the specific class not found, e.g., xyz.dkl.Wonderful.class
2)Find out in which jar this class is
3)Make sure that jar is on your classpath at the production server
This is a long shot: does whoever starts JBoss have permissions to write to all
the directories in and under JBOSS_HOME?
I also vaguely remember there was an issue with the IP Address assigned to the
machine that should be referred to somewhere.
Why use such an old JBoss?

Make both your List and long[] transient by annotating them as such. You will
not be able to persist them in the database, but can use them inside your
SimpleEntity class.
Do not try to do too much in a persistence pojo. It is mainly, as the name
says, an entity to persist.

I've narrowed it down a bit. When entering the IP address to go to the JBoss
Console, all access requests are logged. It must be because of the virtual host
created in jboss-web.xml.
I've looked at the Tomcat Access Log Valve documentation - not a word on
virtual hosts or anything else that
Found the solution in the Wiki pages virtual host how-to. Basically, it
consists of a few more entries in server.xml.
