Is it difficult to debug

[smichea]

I coded the Registration example and obtain the correct form but when
I subit, I obtain an exception whose origin is "jobss-seam-registration not bound".
I understand that Jboss did not manage to find the EJB that contain the register method.
How can we debug such a situation ?
Also could you explain how works this binding, I imagine that you parse classes and detect those with seam annotation, but how does this work ?


Many thanks,
Sebastien.

I found that the problem was in the web.xml file, in the JNDI name pattern for JBOSS, i had to change the name of the web application to reflect the one i defined in the application.xml.

Now it works and I added a dataTable to display the list of users (based on the messages example).
But now I'm struggling with the following exception:

According to TLD or attribute directive in tag file, attribute value does not accept any expressions

that is throw when compiling my JSP at the following line:
<h:dataTable var="usersvar" value="${users}" rendered="#{users.rowCount>0}">

I read on the net that this is because of refering old version of the taglibs, but i used what is provided by the example.

Any help would be appreciated, I really have no clue here

Ii was a simple typo:

"michea" wrote:
value="${users}"

had to be replaced by value="#{users}" ...

The exception message does not give any clue.

Well, the exception message is coming from MyFaces or JSP, so not really much we can do to improve that.
