[jboss-user] [JBoss Seam] - s:link propagation
When you use a s:link tag the tag propagates long-running conversations by default. You can change it's behavior with the use of the propagation attribute: anonymous wrote : propagation - determines the conversation propagation style: begin, join, nest, none or end. Shouldn't there also be a propagation attribute value for the default behavior? Something like propagation=propagate. From what I can understand the jsf tag libs and ejb3 annotations are structured in this manner. If you don't specify (or annotate) an attribute (or field / method) the defaults take precedence. However you have the option of being literal and specifying the attribute or annotation - including literally specifying the default. If you take a look at this previous post http://www.jboss.com/index.html?module=bbop=viewtopict=118268 I think you might get an idea why this could be useful. Currently I have to create duplicate s:link tags to get around this limitation. Thanks for you insight and comments.

[jboss-user] [JBoss Seam] - Exception when redeploying ear with multiple wars.

[jboss-user] [JBoss Seam] - Re: Error selecting object problem
The seam documentation says
anonymous wrote : noSelectionLabel ? specifies the (optional) label to place at
the top of list
| (if required=true is also specified then selecting this value will cause a
| validation error)
so try
h:selectOneMenu required=false value=#{rstReportHome.specialFirm}
id=firm
I'm not sure if JSF will submit a null to setSpecialFirm() when the
non-selection is selected, so you may have to adapt the form's action method to
check for this situation and create a new automatic entity.
P.S. You don't need
private Firm specialFirm;
inside RstReportHome.java.

[jboss-user] [JBoss Seam] - Re: Error selecting object problem
I believe you are right about the tag having problems. I think it is because
the Automatic object you create has not been persisted and won't have an id.
Here's a suggestion for something you could try:
| h:selectOneMenu value=#{rstReportHome.specialfirm} ...
| s:selectItems ... noSelectionLabel=AUTOMATIC/
|
| public Firm getSpecialFirm()
| {
| return getInstance().getFirm();
| }
|
| public void setSpecialFirm(Firm firm)
| {
| if(firm == null)
| {
| // create a new automatic firm.
| firm = new Firm();
| firm.setStuff(stuff);
| }
| getInstance().setFirm(firm);
| }
|
I'm guessing that noSelection returns a null here.
Please post your results. Thanks.

[jboss-user] [JBoss Seam] - Re: DataModel/dataTable for rendering 2 tables
I think you are trying to call getMls() on the listings collection inside
Sellers. The collection does not have this method. You will first need to use a
jsf iteration tag like h:dataTable, ui:repeat or rich:dataTable. Something like
this:
ui:repeat value=#{somebean.sellers} var=seller
| h:outputText value=#{seller.name}
| ui:repeat value=#{seller.listings} var=listing
| h:outputText value=#{listing.mls}/
| /ui:repeat

[jboss-user] [JBoss Seam] - Re: DataModel/dataTable for rendering 2 tables
Just a hunch here, but is your collection a Set? JSF does not iterate correctly through sets. If you are using a set, try changing it to a List, or creating a transient method that instantiates and returns a new ArrayList constructed from the set.

Yes, DataTable can iterate through a One to Many collection of an entity. However there are limitations to what kinds of collections are acceptable.

I agree that a short sentence describing this requirement added to the documentation at 6.7.3 would be helpful to people using the conversationList or switcher. You may also be able to set the conversation description programatically. Something like this I think:((Conversation) Component.getInstance(org.jboss.seam.core.Conversation)).setDescription(String) Not totally sure if this will work as expected. I agree that this behavior is fragile. Perhaps if you create a JIRA you could also ask if in the event the description is not set, the conversationList and switcher fall back to some other description string created from the id or similar.

Personally I think that Michael Yuan's book is currently the best Seam book available for purchase. The documentation that comes with seam is a goldmine of information too, but definitely assumes the reader understands JSF and EJB3. There is another book called Beginning JBoss Seam (Nusairat Apress 2007) which is much more beginner orientated. It has a section outlining the new features of Java 5 and chapters devoted to JSF and EJB3. This book is very light when it comes to seam information but it may be helpful to you at the outset of your journey.

Inside your entity bean change the setter method for the field you want to be
null to something like this:
public void setField(String field)
| {
| if(.equals(field))
| {
| this.field = null;
| }
| else
| {

[jboss-user] [JBoss Seam] - facelet template menu conversation propagation
If you are using a facelets template which displays common menu links on every
page you may require a different conversation propagation attribute value
within the links depending on the view.
In your view page when you want to change the default propagation of the menu
items set the propagation type in a ui:param tag:
ui:composition xmlns=http://www.w3.org/1999/xhtml;
| xmlns:ui=http://java.sun.com/jsf/facelets;
| template=layout/template.xhtml
|
|
|ui:param name=menuPropagation value=end/
|ui:define name=body
| h1Some View/h1
|/ui:define
| /ui:composition
In the menu template create two links for each item one for when the
propagation is not set and the other for when it is:
div
| xmlns=http://www.w3.org/1999/xhtml;
| xmlns:ui=http://java.sun.com/jsf/facelets;
| id=menu
|
| s:link
| rendered=#{menuPropagation == null}
| view=/home.xhtml
| value=Home
| /
| s:link
| rendered=#{menuPropagation != null}
| view=/home.xhtml
| value=Home
| propagation=#{menuPropagation}
| /
|
| s:link
| rendered=#{menuPropagation == null}
| view=/nextMenuItem.xhtml

[jboss-user] [JBoss Seam] - Redirecting to Previous Long Running Conversations
Seam 2.0.0.BETA1
I would like a shopping website that allows users to have multiple carts open
in different browser windows at the same time. Seam's conversation model
appears to provide a solution: use a long running conversation for each cart
and nested conversations everywhere a regular application would use a
conversation.
One of the problems is how to transparently connect a user back to their cart
(most recently accessed session) if they leave the site and come back using a
url without the conversation id? I've tried the following solution:
| pages.xml (fragment):
|
| page view-id=* action=#{conversationManager.manage}
|
| ConversationManager.java:
|
| @Name(conversationManager)
| @Scope(ScopeType.SESSION)
| public class ConversationManager
| {
| private StackString conversationStack = new StackString();
|
| public String manage()
| {
| Manager manager = Manager.instance();
| HttpServletRequest httpServletRequest = (HttpServletRequest)
FacesContext.getCurrentInstance().getExternalContext().getRequest();
| String conversationIdRequestParameter =
httpServletRequest.getParameter(manager.getConversationIdParameter());
|
| if(! manager.isLongRunningOrNestedConversation())
| {
| ConversationEntries conversationEntries =
ConversationEntries.instance();
|
| if(conversationEntries.getConversationEntries().size()
== 0)
| {
| manager.beginConversation();
|
conversationStack.push(Conversation.instance().getId());
| }
| else if
| (
|
conversationEntries.getConversationEntries().size() 0
| conversationIdRequestParameter == null
| )
| {
| while(conversationStack.size() 0)
| {
| String conversationId =
conversationStack.pop();
| ConversationEntry conversationEntry =
conversationEntries.getConversationEntry(conversationId);
| if(conversationEntry != null)
| {
| conversationEntry.redirect();
| }
| }
| }
| }
| else if(manager.isLongRunningConversation())
| {
| try
| {
| if(conversationStack.peek() !=
Conversation.instance().getId())
| {
|
conversationStack.remove(Conversation.instance().getId());
|
conversationStack.push(Conversation.instance().getId());
| }
| }
| catch(EmptyStackException e){}
| }
|
| return null;
| }
| }
For every view the manage method:
- begins a long running conversation for new sessions.
- for requests that have conversations but no conversation id, redirects to
last accessed existing conversation.
I've not tested this extensively but it appears to work as intended.
Because the conversation holds the cart, its timeout should be set to a long
span. However when creating nested conversations it would be preferable for
them to have a short span. Here's where I've run into a problem. I can set the
conversation timeout like so:
Conversation.instance().setTimeout(int);
but as soon as I go to the next page the timeout will be back to the default
setting. I've would like to use an approach like:
ConversationEntries.instance().getConversationEntry(2).setTimeout(int);
which would set the ConversationEntry dirty, but this method is not visible.
Here are my questions:
=
- How do you permanently change a conversation's timeout?
- Is there a better multiple cart solution without hijacking the seam
conversation model? (e.g. storing the carts in the sesssion and creating
management similar to conversations)
- If this is an acceptable solution would it be better implemented as a servlet
filter instead of mapping an action to the * view in pages.xml?
=
Thanks in advance for your feedback.

Yes this is easy to do without using a trigger.
You could map as a One-to-One Unidirectional or a One-to-One Bidirectional.
e.g. One-to-One Unidirectional
| @Entity
| public class Employee
| {
|private int id;
|private Address address;
|
|@Id
|@Column(name = eno)
|@GeneratedValue

|@OneToOne
|@PrimaryKeyJoinColumn
|public Address getAddress() { return address; }

Depends on whether you want to use Seam 1.2.1.GA or 2.0.0.BETA1. Seam 1.2.1.GA is the current stable release and works with jboss-4.0.5.GA. Seam 2.0.0.BETA1 is the next version of seam and works with jboss-4.2.0.GA (maybe 4.2.1.GA - anyone?). I've not run into any problems with Seam 2.0.0.BETA1.

[jboss-user] [JBoss Seam] - Seam-gen build corrupts images
Seam 1.2.1.GA
I have experienced corrupt image files when creating new seam-gen projects in a
Linux environment (Debian Ubuntu) for some time. When creating a new seam-gen
project in a WindowsXP environment the file corruption does not occur.
There are only 3 files that are effected by this problem:
/view/img/cal-next.png
/view/img/cal-prev.png
/view/img/dtpick.gif
So it has not been a big deal to copy the files over manually.
I've done a little research into the problem and I think it is related to the
use of a filterset in the ant copy task on lines 602-605 of the seam-gen build
file $SEAM_HOME/seam-gen/build.xml
|
|
| copy todir=${project.home}/view
| fileset refid=view/
| filterset refid=project/
| /copy
The ANT documentation (http://ant.apache.org/manual/CoreTasks/copy.html) says:
anonymous wrote : Note: If you employ filters in your copy operation, you
should limit the copy to text files. Binary files will be corrupted by the copy
operation. This applies whether the filters are implicitly defined by the
filter task or explicitly provided to the copy operation as filtersets. See
encoding note.
|
When copying the contents of the image directory within a copy task (without
any filters) the file corruptions do not occur.
Would it be appropriate to post a JIRA issue with a patch?

[jboss-user] [Installation, Configuration DEPLOYMENT] - Multiple WARs with SSL and common data source configuration.
I have a requirement for two SSL enabled shopping websites to share the same
data source. Both websites are owned by the same company. Some of the products
are unique to one website and some products are common to both - hence the
shared data source to accurately reflect inventory levels.
I have an implementation using Apache2 and mod_jk but I would be very grateful
to hear any tips for alternative solutions.
In particular please clarify the following:
- Can WARs inside the same EAR utilize different SSL certificates?
- Can EARs running within different VMs but not within a cluster share a common
Persistence Provider Instance (factory / secondary cache)?
Here are the details for my current implementation.

[jboss-user] [Installation, Configuration DEPLOYMENT] - NIC address binding granularity
When starting the JBoss you may specify an address binding option like this: -b x.x.x.x(bind to network address x.x.x.x only) | | or | | -b 0.0.0.0(bind to all available network addresses) How do you configure the server to connect to more than one individual network address, but not all? I've taken a look at the source code and it seems that network binding is limited in this fashion. Have I missed something or would a JIRA feature request be reasonable?

The entity beans generated by seam-gen are EJB3 beans. I don't see any reason why you should not be able to use them directly in a stand alone java application (outside of JBoss). You will have to create an application managed persistence context to do so.

[jboss-user] [JBoss Seam] - Re: Class Inheritance and the EntityHome Framework Class
It turned out to be pretty simple to get it working.
@Entity
| @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
| @DiscriminatorColumn(name = discriminator, discriminatorType =
DiscriminatorType.STRING)
| public abstract class BaseClass implements Serializable
| {
| private String discriminator;
|
| @Column(name = discriminator, length = 16, insertable = false,
updatable = false)
| @Length(max = 16)
| public String getDiscriminator()
| {
| return discriminator;
| }
|
| public void setDiscriminator(String discriminator)
| {
| this.discriminator = discriminator;
| }
| }
@Entity
| @DiscriminatorValue(SubClassOne)
| public class SubClassOne extends BaseClass
| {
| public SubClassOne()
| {
| discriminator = SubClassOne;
| }
| }
@Entity
| @DiscriminatorValue(SubClassTwo)
| public class SubClassTwo extends BaseClass
| {
| public SubClassTwo()
| {
| discriminator = SubClassTwo;
| }
| }
@Name(ClassHome)
| public class ClassHome extends EntityHomeBaseClass
| {
| // set a default subclass to instantiate
| private String discriminator = SubClassOne;
|
| @Override
| protected BaseClass createInstance()
| {
| BaseClass baseClass;
| if(SubClassOne.equals(discriminator))
| {
| baseClass = new SubClassOne();
| }
| else if(SubClassTwo.equals(discriminator))
| {
| baseClass = new SubClassTwo();
| }
| else // unknown class
| {
| // throw exception
| }
| return baseClass;
| }
|
| public String getDiscriminator()
| {
| return discriminator;
| }
|
| public void setDiscriminator(String discriminator)
| {
| this.discriminator = discriminator;
| }
| }
When I want to create a new SubClass I set a JSF control to call
setDiscriminator in the BaseClassHome object which it uses in turn to determine
the type of subclass to instantiate.
I'd appreciate any comments or advice if this seems like a misuse of the seam
framework. Thanks.

I created a website with the .seam extension but found that although my site was indexed by Google and Yahoo, it was not cached. I changed the extension for seam pages to .html and then Google and Yahoo no longer indexed the site at all. Because the jsf components render xhtml elements I think maybe the engines are unhappy with the use of the .html extension (although MSN works fine). At the moment I'm going back to the .seam extension. Please share your experiences and insights in this regard. Thank you.

[jboss-user] [JBoss Seam] - Re: Search Engines and Seam
Does this sound like a plausible explanation for the search engine behavior? Seam-gen creates an index.html page that contains: html | head | meta http-equiv=Refresh content=0; URL=home.seam | /head | /html Search engine retrieves this page, caches it and then proceeds to index and cache the home.seam page. The root page for your domain ends up being a blank page. Possible solution?

[jboss-user] [JBoss Seam] - Re: Search Engines and Seam
I've tried the above with both home.seam and home.xhtml as the target welcome page but with no success. Maybe because the server tries to access the file directly rather than letting seam intercept the file by extension? Solution attempt 2 - create a robots.txt file that directs the search engines to the correct root page for the site (home.seam).

[jboss-user] [JBoss Seam] - Re: Search Engines and Seam
Previously I stated that search engines were not caching pages, but it would be more accurate to state that they were caching blank pages (sorry for the imprecision). It seems that robots.txt can only be used to define areas to not visit, so that won't work either. Currently I'm thinking about the following approach: html | head | meta http-equiv=Refresh content=0; URL=home.seam | meta name=robots content=noindex,follow | /head | /html(Tell the search engine to follow the redirecting index.html page, but not to index it.) Ideally though, I would like to have JBoss load my home.seam page by default, rather than load an index.html page with a redirect. Is this something that is possible and how do you configure JBoss to do this? Thank you for everyone's help.

[jboss-user] [JBoss Seam] - Class Inheritance and the EntityHome Framework Class
I've been using a
public class BaseHome extends EntityHomeBase
class to manage persistence for a collection of sub class entities that inherit
from Base.
For sub classes which have been persisted to the database things work as
expected. I can setId(), getInstance(), and persist state changes to the
database.
I would like to create new entities using BaseHome, but I need a way to specify
which concrete subclass should be instantiated. Here's what I've tried to do:
public class BaseHome extends EntityHomeBase
| {
| @Override
| public void create()
| {
| setEntityClass(Subclass.class);
| super.create();
| }
| }
|
| public class Subclass extends Base{}
|
With the result:The method setEntityClass(ClassBase)
| in the type HomeEntityManager,Base
| is not applicable for the arguments (ClassSubclass)
Am I using the EntityHome framework in a manner that was never intended? Should
I build my own bean for managing this object heirachy?
As always, I greatly appreciate the insights the members of this forum share.

[jboss-user] [JBoss Seam] - Re: Injection of a stateless session bean (SLSB) into anothe
Yes that worked! Thank you to both Matt and Knass.
My classes look like this:
@Local
| public interface Simple
| {
| public abstract String getName();
| }
|
| @Stateless
| @Name(simpleBean)
| public class SimpleBean implements Simple
| {
| private String name = simple;
|
| public String getName()
| {
| return name;
| }
| }
|
| @Local
| public interface Container
| {
| public abstract String getName();
| }
|
| @Stateless
| @Name(containerBean)
| public class ContainerBean implements Container
| {
| @In(create=true)
| Simple simpleBean;
|
| public String getName()
| {
| return simpleBean.getName();
| }
| }
I'm still left wondering about the implementation details within the EJB
container. I suspect that the ContainerBean is issued a proxy stub to which it
maintains a reference. This would allow different pooled SimpleBeans to service
the getName() method call from the ContainerBean. In this scenario I think
things should work as planned. Any further insights appreciated...

[jboss-user] [JBoss Seam] - Injection of a stateless session bean (SLSB) into another SL
I've set up a SLSB as follows:
@Stateless
| @Name(simpleBean)
| public class SimpleBean implements Simple
| {
| public String getName()
| {
| return simple;
| }
| }
|
The simpleBean bean can be accessed from a EL expression on a facelets page
without any trouble.
I have another SLSB like this:
@Stateless
| @Name(containerBean)
| public class ContainerBean implements Container
| {
| @In
| SimpleBean simpleBean;
|
| public String getName()
| {
| return simpleBean.getName();
| }
| }
However, when I try to access the getName method of containerBean I run into
the following error:
Caused by: org.jboss.seam.RequiredException: In attribute requires non-null
value: containerBean.simpleBean
| at org.jboss.seam.Component.getValueToInject(Component.java:1919)
|
If I change simpleBean into a JavaBean provided and annotate containerBean
with In(create=true) the injection works as expected, but if I create a similar
annotation without changing simpleBean to a JavaBean I get an error like this:
... 95 more
| Caused by: java.lang.IllegalArgumentException: Could not set field value by
reflection: ContainerBean.simpleBean on: com.somedomain.stateless.ContainerBean
with value: class org.javassist.tmp.java.lang.Object_$$_javassist_3

| ... 117 more
| Caused by: java.lang.IllegalArgumentException
| at
sun.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorImpl.java:63)
|
The seam documentation makes it clear that SLSB's live in the stateless context
which is not included in the context search. Is this why my simpleBean can
not be found for injection into my containerBean? I'm not familiar with how
seam and the ejb3 container interact during instantiation of these SLSB objects
into pools - perhaps the beans are being created out of order? Perhaps I'm
trying to do something way beyond the intention of the EJB3 SLSB specification.
I'm pretty much resolved that what I'm trying to do here is not a great idea.
Is there a different way to dynamically assign a reference to a SLSB to a
different SLSB when a method is called? I would be very interested to hear
other peoples insight and wisdom on the subject. Thanks in advance and kind
regards.

However as soon as I deploy an ear with a virtual host configuration I am unable to access this directory. I've tried changing the name attribute of the host element inside the jbossweb-tomcat55.sar/server.xml file to reflect the hostname (as opposed to localhost) with no success.

[jboss-user] [JBoss Seam] - Re: Page Redirection with Seam Navigation
Thank you Gavin, that was the piece of the puzzle I was missing. My final configuration in WEB-INF/pages.xml looks like: page view-id=/virtual/path/to/alias_file.xhtml action= | navigation | rule | render view-id=/real/path/to/real_file.xhtml/ | !-- or redirect -- | /rule | /navigation | /page When you create a granular configuration file like [page_name].page.xml the view-id attribute does not seem to have any effect. The view-id appears to be determined by the path and filename of the [page_name].pages.xml file. I presume this is the expected behavior?

[jboss-user] [EJB 3.0] - Stateless Session Beans - Static Variables - Concurrency and
I've been trying to find out what (if any) consequences there may be for
implementing static class variables inside ejb3 stateless session beans. I've
created some beans in this manner and they appear to function as I would expect
on a standalone JBoss server, but I'm concerned that this technique may break
clustering.
Essentially I'm trying to cache seldomly updated data (in the database) that is
requested very frequently on the web front end.
@Stateless
| public class CatalogBean implements Catalog
| {
| static boolean current = false;
| static String data = null;
|
| public void refresh()
| {
| current = false;
| }
|
| public String getData()
| {
| if(! current)
| {
| update();
| }
| return data;
| }
|
| private void update()
| {
| data = getDataFromTheDatabase();
| current = true;
| }
| }
Beans that are responsible for CRUD call the refresh method on this stateless
bean - in turn updating their shared cache. My (hazy) understanding is that the
ejb container is responsible to ensure that only one thread at a time can
access a bean? Does this mean that different instances can be accessed
concurrently - and therefore I could have syncronization issues? I suspect that
static variables may be a bad idea - especially in a clustered environment.
Perhaps there is a different or recomended approach that I have not considered?
Thank you in advance for all your comments and insights.

[jboss-user] [JBoss Seam] - Re: How to implement cross cutting classes jar in a seam ear
Small note: You need to make sure you have an empty seam.properties file in the root of your jar file so the seam components inside the jar will be deployed.

[jboss-user] [JBoss Seam] - How to implement cross cutting classes jar in a seam ear?
I'm trying to split my utility classes away into their own jar file so I can easily reuse them from different seam projects and maintain a single source tree. I've created a jar containing the classes but I have not been able to add the jar into my ear (or war) correctly. I've tried a few different approaches with no success: - adding the jar to project.ear/project.war/WEB-INF/lib (class not found) - adding the jar to project.ear/ and adding a module tag inside application.xml (bean class has no local, webservice or remote interfaces defined) - adding the jar to project.ear and adding a loader-repository tag inside jboss-app.xml (expected only one loader-repository tag) Some of the classes inside my jar are seam components which is why I've posted this question in the seam forum. My project.ear is esentially a generic empty seam-gen project to which I've added my jar.

[jboss-user] [JBoss Seam] - Re: How to implement cross cutting classes jar in a seam ear
I've got my utility classes working. Here's how: Added utility.jar to the root of project.ear. Edited project.ear/META-INF/application.xml and added module | javautility.jar/java |/module Thanks for yout reply, I was not seeing that this approach worked because I had introduced another similar error in a different part of the application. This has lead me to seek an answer to another question. If you want to deploy fully fledged statefull or stateless ejb3 session beans would you use a tag like this (in application.xml): module | ejbejb_bean_classes.jar/ejb |/module I'll give it a try.

[jboss-user] [JBoss Seam] - Re: How to use @Id @GeneratedValue(strategy=GenerationType.A
In Enterprise JavaBeans 3.0 (O'Reilly 2006) it states The AUTO strategy tells
the persistence provider that you are allowing it to generate the key for you
(page 94).
I don't specifically know the Hibernate implements this feature, but might I
suggest that you utilize the features of your database to create primary keys
instead.
With Postgresql you could use a mapping like this:
@Id
| @Column(name = id, unique = true, nullable = false)
| @SequenceGenerator(name=identifier, sequenceName=ppl_id_seq,
allocationSize=1)
| @GeneratedValue(strategy=GenerationType.SEQUENCE,
generator=identifier)
| @NotNull
| public int getId()
| {
| return this.id;
| }
In this manner Hibernate would assign primary keys from the Postgresql sequence
rather than internally. This would allow Hibernate to play nicely with other
database users.

[jboss-user] [JBoss Seam] - SessionBean Interface @Local Annotation
I was tracking down an error in my code and noticed that the Seam example code may be missing an annotation. Specifically the ShoppingCart.java interface in the DVD Store example does not have a @Local annotation although it does appear to define a locally accessed stateful session bean. Is the EJB3 @Local annotation superfluous when using Seam?

[jboss-user] [JBoss Seam] - SeamLoginModule EntityManager injection difficulties
I am running Seam version 1.1.6 on a JBoss 4.0.5.GA server.
While following the example from the Seam documentation (page 124) for creating
a SeamLoginModule authentication method I have run into the following error:
09:37:41,228 ERROR [SeamLoginModule] Error invoking login method

This suggests that Seam is unable to locate and inject the entityManager by its
component name. The relevant java bean that the login component is calling is
as follows:
@Name(authenticator)
| public class Authenticator
| {
| @In EntityManager entityManager;
|
| public boolean authenticate()
| {
| return true;
| }
| }
For completeness here, is the form that is calling the validation:

I have also tried to annotate the EntityManager object in the following ways:
@In(entityManager) EntityManager entityManager;
|
| @In(value=entityManager) EntityManager entityManager;
but have recieved the same error.
My configuration was generated by seam-gen and the authenticate method works
fine until I try to inject an EntityManager into the component.
I will create a Stateful Session Bean in order to try to inject the
EntityManager by the EJB3.0 annotation @PersistenceContext rather than Seam @In
annotation.
Could this be caused by a filter loading order? I've looked at web.xml and it
does not seem to be the cause. I think too that the identity component is a
Seam component (ie. eats its own dogfood), therefore should not be a problem,
Maybe the identity component is instantiated before other components like the
entity manager?
P.S. Thank you Gavin King for all your past helpful answers.

That worked like a charm. This leaves me wondering how some of my other java bean componenets manage to have Seam inject the EntityManager (without create=true).

[jboss-user] [JBoss Seam] - Tomahawk Setup and JSF Library Compatibility
Yesterday, I configured my JBoss Seam application to use Tomahawk JSF components. I copied tomahawk.jar and commons-fileupload.jar to my $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/jsf-lib directory. After adding these jars to the server I configured my web-xml file as described by the Tomahawk website (http://myfaces.apache.org/tomahawk/index.html). Additionally I made the changes outlined on the Tomahawk wiki (http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk) to allow the use of these JSF components with Facelets. I created a page with the calendar component and it appears to be working correctly. After I had made these changes and tested the calendar component I discovered the Seam documentation (version 1.1.6.GA) states: We do not recomend the use of the Tomahawk tag library. Please comment on my use of the jbossweb-tomcat55.sar/jsf-lib directory for deploying the jar files. Is this considered part of the Server Classpath? Please briefly explain why the use of Tomahawk is not recomended and describe what kinds of problems might be encountered. Does this mean that Seam also precludes the use of other JSF tag libraries (eg IceFaces)?
