[JBoss Seam] - Re: Tomcat + Embedded EJB
by KnisterPeter
When I change my EJB to have the EntityMangager annotated with @In instead of @PerstistenceContext it does get deployed in the ejb server , but then no EntityManager is injected and I get the following exception when calling a method on that bean:
org.jboss.seam.RequiredException: In attribute requires non-null value: register.em

[JBoss Seam] - Seam application packaging question
by leezard
Hi all,
I'm trying to build seam sample application using maven.
I have only a few dependencies in my project:
seam-1.2.1, seam-ui-1.2.1, facelets and java5 api (just for development).
Now when I package whole application into EAR maven includes all seam's dependencies into this EAR. Those dependencies are:
hibernate-annotatnions
asm
hibernate
commons-logging
jta
persistence-api
asm-attrs
antlr
jms
javaassist
ecache
dom4j
cglib
commons-collections
I read "packaging" chapter of seam doc, and there is shown sample EAR structure of seam application. There are only a few jars included:
seam
seam-ui
facelets
el-api
el-ri
Now, do I have to exclude all the dependencies from my EAR and include only jars mentioned in seam doc? Are the other jars avalilable in Jboss already?

[JBoss Seam] - @In @Out @In(create=true) confusion
by dreuzel
The problem
with annotation is that one does not understand what happens behind the screen.
I'm using a ejb3-hibernate entity definition(simply defined)
in the pojo
@In tableclass xyz is used
I'm sometimes receving exceptions the xyz nullpointer exception
because (i think) I conditionaly use XYZ IN MY FACELET xhtml definition
depending on some other pojo variable i render the variables pointing to XYZ, conditionaly
as in some cases xyz.variables(the prime key) are not rendered the @in initialized xyz is not initialised... ====> exception
the exception occurs during page initialisation, during the rendering, prior to calling @begin so there is very little i can do to solve the bug
it does not help using @out nor @in(create=true)
can anyone confirm my theory ??? (seam 1.2.1)
any chance for improvement with 1.3 ?
