Could not instantiate Seam component :/

[yacho]

OK so heres another problem i stumbled upon :

i Have statefull Session bean that defines my component

i get the following error when executing #{userManager(newUser)} :

21:46:24,625 WARN [lifecycle] Could not instantiate Seam component: userManager
org.jboss.seam.InstantiationException: Could not instantiate Seam component: userManager
at org.jboss.seam.Component.newInstance(Component.java:1853)

even trough it deploys ok and its loaded :

21:44:43,625 INFO [Component] Component: userManager, scope: EVENT, type: STATEFUL_SESSION_BEAN, class: sessionbeans.UserManagerBean, JNDI: \UserManagerBean/local

My Session Bean looks like this :

@Stateful
@Name("userManager")
@Scope(EVENT)

public class UserManagerBean implements UserManager, Serializable {

 @PersistenceContext
 EntityManager em;

 @In
 public String register(User newUser) {
 User existing = (User) em.createQuery("from User where username={#newUser.username} and passwd={#newUser.passwd}").getSingleResult();

 if (existing != null) {
 em.persist(newUser);

 return "registered";
 } else {
 return null;
 }

 }
 @Remove
 public void destroy() {}

It Seems to be ok - so wheres the fuss ?
is the JNDI path correct ? because im a bit confused about the slashes :/

I bet there is more info after:

21:46:24,625 WARN [lifecycle] Could not instantiate Seam component: userManager
org.jboss.seam.InstantiationException: Could not instantiate Seam component: userManager
at org.jboss.seam.Component.newInstance(Component.java:1853)

[yacho]

OK, please paste your components.xml contents and tell me the name of your ear file....

[yacho]

components.xml : http://phpfi.com/265102

My project ear is named foo1.ear

I had to paste variables from components.properities cause somehow eclipse threated @something@ as error (in debug and JNDI path - so probably thats the problem but i dont know how to correct it...

[dhinojosa]

Well, change:

 <core:init debug="true" jndi-pattern="\#{ejbName}/local"/>

to:

 <core:init debug="true" jndi-pattern="foo1/#{ejbName}/local"/>

where foo1 is the name of your ear file. Be sure to change that when your ear file changes. The @.......@ you saw before was a filter token used by seam-gen. What is does is automatically plugs in the name of the ear automatically using ant. You can manually manage it or revert it back. Your call.

Sweet Man !

Works like a charm.

Since I pasted in My Bean i have question :

newUser Entity is Event scoped and is bound to a form that has register(User newUser) apached to it.

The thing is newUser is always null - my question is why ? Dosent the JSF values get Bound to entity before invoking a register Action so that injected parameter is meaningful ? or is it about the Scupe of newUser entity ?

[dhinojosa]

Well if the user has attempted to be invoked yet....Try

@In(create=true)
