[EJB 3.0] - mappedBy reference an unknown property
by DaHunter
Hi,
I'm trying to create a one to many bidirectional relationship but am having some problems. Whenever I deploy the application in JBoss I get an error. I've searched online, and in an EJB 3.0 book and as far as I know I am doing things correctly. Below are my 2 classes, the tables and the error from JBoss. If anyone can point me in the right direction it would be helpful. I am using JBoss version 4.0.4.GA. This is my first EJB application, so I appoligize if this is a simple error. Thanks!

[JBoss Seam] - One to one doubt
by nandolins
i having some problems trying to persist an object with a one to one relation, it is working, but there must be a better way. Let me show you:
View:
| <tr>
| <td>Codigo</td>
| <td><h:inputText value="#{assuntoProcesso.codigo}" required="true" /></td>
| </tr>
| <tr>
| <td>Descrição</td>
| <td><h:inputText value="#{assuntoProcesso.descricao}" required="true" /></td>
| </tr>
| <tr>
| <td>Codigo Natureza</td>
| <td><h:inputText value="#{naturezaProcesso.codigo}" required="true" /></td>
| </tr>
| <tr>
| <td>Descrição Natureza</td>
| <td><h:inputText value="#{naturezaProcesso.descricao}" required="true" /></td>
| </tr>
|
Action:
@In
| @Out
| @Valid
| private AssuntoProcesso assuntoProcesso = new AssuntoProcesso();
|
| @In
| @Out
| @Valid
| private NaturezaProcesso naturezaProcesso;
|
And setting the variable naturezaProcesso to assuntoProcesso then.
but this looks kind of stupid, declaring the two variables, it would be much more simple to use a view like this:
| <tr>
| <td>Codigo</td>
| <td><h:inputText value="#{assuntoProcesso.codigo}" required="true" /></td>
| </tr>
| <tr>
| <td>Descrição</td>
| <td><h:inputText value="#{assuntoProcesso.descricao}" required="true" /></td>
| </tr>
| <tr>
| <td>Codigo Natureza</td>
| <td><h:inputText value="#{assuntoProcesso.naturezaProcesso.codigo}" required="true" /></td>
| </tr>
| <tr>
| <td>Descrição Natureza</td>
| <td><h:inputText value="#{assuntoProcesso.naturezaProcesso.descricao}" required="true" /></td>
| </tr>
|
But i getting errors with this one, anybody can help me?

[JBossWS] - Re: Handling anyType
by centecbertl
Hi,
unfortunately I ran into the very same problem when using any of my
web-services providing methods consuming "<complexType ..." arguments with nillable elements of any type.
My Environment: JBoss 4.0.4.GA (EJB3-RC8 patch and update to JBossWS 1.0.3 applied/) which takes any web-mehtod argument with nillable elements!
The problem was introduced with the update to jbossws 1.0.3 (jbossws 1.0.2 had no problem with the very same server and client code)
Before I start digging into the code or porting my services to a different web-service provider I would like to ask whethere there is any workaround/patch which could be applied until jbossws-1.1.0 for which the fix is scheduled is out?
- downgrading to jbossws 1.0.2 is not an option due to other problems which were actually fixed with jbossws 1.0.3
- waiting until Oct. 31 (jbossws 1.1.0 release?) is also no option.
Many Thanks,
Bertl
