[JBoss Seam] - Question on Injection an Context
by hasc
Hi,
i have some trouble propably because of a misunderstanding with resrouce injection.
I have a Stateful bean in conversation scope. The bean is responsible for managing some user input. The user data is stored in an object (calculation) which is injected in the manager bean.
| @Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name("manager")
| public class CalculationManagerBean implements CalculationManager {
|
| @In Calculation calculation
| }
|
Now on a special page i want to manipulte a list wich is an attribute of the calculation object. I thought a component with ScopeType.PAGE is a good candidate to offer the methods to add change and remove list elements. So i wrote a component which injects the calculation object.
| @Name("listmanager")
| @Scope(ScopeType.PAGE)
| public class ListManager implements Serializable{
|
| @In
| Calculation calculation;
|
| @DataModel
| List<ListItem> list;
|
| public void addItem() {
| list.add(item);
| calculation.setList(list);
| }
|
|
I want to save the manipulated list in the calculation object whenever the list changes. The problem is that if i call the setter method it has no effect on the calculation method.
I guess is accociated with the scope, so conversion is longer than page. But i dont have a proper solution or a better way to achieve what i want.
Help would be great.
regards,hasc

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Closing a result set you left open!, MySQL

Hm...
I have no idea, but maybe you should change your persistence xml a little bit
I got a error because I had not entered the Hibernate Dialect
| <properties>
| <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
| </properties>
|
how do you access those TestBean?
I was told to write an extra class with source code like this
| try
| {
| Properties properties = new Properties();
| properties.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| properties.put("java.naming.factory.url.pkgs","=org.jboss.naming:org.jnp.interfaces");
| properties.put("java.naming.provider.url","jnp://localhost:1099");
|
| InitialContext iContext = new InitialContext(properties);
|
| TologDatabaseQueryResponderRemote remote =
| (TologDatabaseQueryResponderRemote) iContext.lookup("TologResponderEAR/TologDatabaseQueryResponder/remote");
| }
| catch ( NamingException e )
| {
| throw new DatabaseQueryResponderException("NamingException while trying to connect to a remote interface:\n"+e.getLocalizedMessage());
| }
|
But I have to admit, that I also have the next problems - but ok - none of your business - you have your own problems...
Greetings
