RE: [JBoss-user] problem with stateful session bean

RE: [JBoss-user] EJB in ear referencing EJB outside of ear
Hi, If you deploy a bean outside an ear file (e.g. as a bean-jar not as another ear file) you can reference the bean only with it's JNDI name. You can't user java:comp/env/ejb namespace bacause that can only be used within one enterprise archive. So if the jndi name of your bean is MyBean then just call InitialContext.lookup(MyBean) and you'll be alright. (at least I am when I do this). If the problem persists, maybe you can provide a stacktrace for the CommunicationException.. cheers, JOost. -Original Message- From: Richard Doust [mailto:[EMAIL PROTECTED]] Sent: Friday, November 16, 2001 4:51 AM To: [EMAIL PROTECTED] Subject: [JBoss-user] EJB in ear referencing EJB outside of ear Hi. I'm confused by the J2EE Spec. I know it's possible for an EJB packaged in a jar and deployed inside of an ear to reference an EJB that does not exist inside the ear. I have gone from packaging all EJBs inside the ear to deploying one externally, (on my way to deplolying most of them externally), so that a different application deployed in the same container can access the EJBs without having to have the EJBs packaged inside two different ears. I've modified my deployment descriptors according to the specification, and when I run JBoss, the JNDIView shows me that all of the namespaces are established as I would expect. Yet, when I try to access the externally deployed EJB from an EJB inside the ear (doing a lookup on its Home using InitialContext), I get a CommunicationException. From the description, it seems like a weird exception to have. If anyone is interested in trying to help me figure this out, I could provide more details.

However, it appears to me that jboss 2.2.1 and jboss 2.4.1 behave very differently in dealing with the pooling of stateless session beans: I deployed exactly the same beans in both jboss versions, with the same (in fact: the default) container configurations and investigated jboss-logging and some customized logging in our beans about their life-cycle events. In 2.2.1, this kind of logging convinces me that stateless session beans are indeed pooled and reused. However it seems that in 2.4.1 this is no longer the case: no-arg-constructors, setSessionContext() and ejbCreate() methods are called over and over again, even when I reduce the pool-size to say 2 instances! please help!!!

I had
put all thejar files of $JBOSS/client into classpath, then it is
OK.
perhaps
some jar file that seem to be not important
isindeednecessary.
I use
jboss2.2.2
In
linux, I cannot get http://localhost:1099,
the error is that target page cannot be found.
but In
windows, I can truly get http://localhost:1099, the result is a page
filled with
disordered characters.
thanks
for you all.

I think, as that
was mentioned, it would be sufficiently to add to classpath jndi.jar and jnp-client.jar from JBOSS_HOME/client.

also to Alex:
I had done, but it doesn't work... when I see http://localhost:1099 this page can not be found
Does it hint that jndi provider does not work?
thanks
the error is :
" Cannot instantiate class:
org.jnp.interfaces.NamingContextFactory"
You need to set the class path to jnp-client.jar in
jboss/client directory

Hi, If you are using BMP this is perfectly valid, then in the ejbFindByPrimaryKey you throw an ObjectNotFoundException when the obsolete_indicator column says Y Joost. -Original Message- From: Adam Lipscombe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 18, 2001 1:45 PM To: JBoss User Mailing List Subject: [JBoss-user] EJB Entity design question: Can ejbRemove() be used to modify a row in the DB? Folks, I have several entity EJB's that model database tables. Rows in the tables are never physically deleted, but rather they are logically deleted by setting a obsolete_indicator column Y. Can I use ejbRemove() to simply modify the row (setting this flag to Y) or will this break application server caching? Are there any other reasons why I should not use ejbRemove()?
