Inject a POJO

[timerons]

hello

we are running a nice application with seam :-)

no we like to inject a pojo. this class is in a jar that is in the classpath. we do not want this to be annotated as ejb or a seam component.

i try use @In but it was always null.

i guess i have to declare it in a config file. but i do not know where.

thx :-)

Hi

Is the pojo annotated with Seam annotations?
If it is there a seam.properties file in there so that it is scanned by Seam at startup?

If the pojo is discovered as a Seam component you should be able to see this in the log when the server starts up.

If not you could define the pojo as a bean in components.xml or in Spring or perhaps via faces-config.xml.

Seam can only inject/outject ejbs and pojos which are manageable and regocnized at startup of the web app.
There are two (or even more ways) to inform seam about these manageable objects:

• annotations


• components.xml

u have to use components.xml, if u cannot or do not want to recompile (using name-annotations) the target-class itself

example

<component name="someName" class="FULL_QUALIFIED_NAME_OF_THE_CLASS_U_WANT_TO_MAKE_MANAGABLE" auto-create="true" scope="EVENT" >
</component>

hello

thanks this works well in a normal bean. thanks a lot for you help.

now i like to use this bean the authenticator

every thing work well except of the injection of the ldapServiceAuthenticate

i did the following entry's in the components.xml:

<security:identity authenticate-method="#{authenticator.authenticate}"/>
<component name="ldapServiceAuthenticate" class="com.xxx.ldap.LdapServiceAuthenticate" auto-create="true" scope="application">

in my beans i use the following:

@In(create=true)
private LdapServiceAuthenticate ldapServiceAuthenticate; 

- in a normal bean i get the ldapServiceAuthenticate injected :-)

- in my authenticator i let inject the LDAPService (work well), that get the ldapServiceAuthenticate injectet that is always null.

other things work well when we like that to be injected:

@Stateless
@Name("authenticator")
public class Authenticator implements IAuthenticator {
        @In
        Identity identity; 

        @Out(required = false, scope = SESSION)
        private User user;

        @EJB
        private IConfigurationDAO configDAO;
        
        @EJB
        private IUserDAO userDAO;
        
        @EJB
        private ILDAPService ldapService;
        
        @In
        private FacesMessages facesMessages;

@Stateless
public class LDAPService implements ILDAPService {
        
        @In(create=true)
        private LdapServiceAuthenticate ldapServiceAuthenticate; 

that works well:

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("productCreationCtrl")
public class ProductCreationController implements IProductCreationController {

        @In
        private FacesMessages facesMessages;
        
        @In(create=true)
        private LdapServiceAuthenticate ldapServiceAuthenticate; 

may someone has a clue why i can't inject something in the Authenticator or better in the LDAPService

best regards
