| #2 and #3 dont seem to be a problem (though i am not sure why the sqljdbc_auth.dll is required). However, i would revert back #1. More so because the exception that you posted, does show something related to JSF. How exactly did you update the JSF version? Which all files did you change and where?
I've just downloaded new version form mojarra and overwrited two libs here: jboss-4.2.2.GA\server\default\deploy\jboss-web.deployer\jsf-libs\

| Undo the changes to the JSF jars and use Java 1.5 and try accessing the JNDIView. See if it works. Post back with details, if it doesn't.

Ok, here are the results:
1. With JSF 1.2_04 and JDK 1.5.0_09-b01 - there is NO exceptions.
2. With JSF 1.2_07 and JDK 1.5.0_09-b01 - there is this exception :(
It's very sad, because I can't work with JSF 1.2_04 because my App uses JBoss RichFaces version which needs JSF 1.2_07 for bugless work.
How do you think, jaikiran, should I report this exception to mojarra or it's JBoss app server fault?
And thank you for your help very much. At least we know now where the problem lies...

[EJB 3.0] - Eager fetching missing an element when retrieved remotely no
by Bigdaddy
I am not sure if this forum is where this problem should be posted, but here it goes.
Using:
Java: 1.5.0_15; Java HotSpot(TM) Client VM 1.5.0_15-b04
JBoss AS: 4.2.2.GA
I am trying to implement eager fetching with a parent-to-child (many-to-many) and child-to-grandchild (many-to-many) relationship setup. After all entities are created and I retrieve the grandchildren with EAGER fetching, I am able to iterate through the list of grandchildren and view the grandchildren with it's related children and the children's related parents BEFORE leaving the JBoss server to return the results to a remote client. AFTER leaving the server and the remote client receives the results I iterate through the same grandchildren and see that the parent does not contain the same children as was present before the data left the server. If you run the files I have provided you will notice output from the server log console does not match output from the remote client. It is as if the returned information is being cut off. The child sizes for parentId=402881821a263a42011a26a349aa00ab are different (JBossAS = 2 and remote client = 1) in this sample output. The output from the server side is what is expected.
Sample output

I do not know if there is something wrong with Java, JBoss remoting, EJB3, etc. Hopefully, someone will be able to point out something I may have overlooked or something that I may have misunderstood.

[Installation, Configuration & DEPLOYMENT] - Re: How to configure multiple instances/nodes/domains?
by pkostic
Thank you.
I have a couple of questions regarding what I've read.
1) I'm going to work with alternate ports. I installed EAP using a graphic installer and I can not find /conf/deploy/binding-service.xml file in any selected configuration dir (all, defautl, production, minimal). Please read the paragraph at the bottom, would it be a mistyped error regarding jboss.service.xml?
2) The 4446 port bug is just for JBoss 402 version?
Regards.
---------------------------------------------------
* If you installed JBoss using the installer, firstly, make sure you selected the "binding-service" package from the JMX group and then, open /conf/deploy/binding-service.xml file in the selected configuration and modify the "Service Binding" section as explained in the previous paragraph.
* See $JBOSS_HOME/docs/examples/binding-manager/sample-bindings.xml "ports-default" entries for all jboss port properties. default-bindings.xml provides a quick view of jboss-4.0.2 default port settings, but it may not reflect your installation's port settings.
* NOTE: JBoss AS 4.0.2 has a known bug : one of the ports (4446) is not included in the sample-bindings.xml file and therefore will continue to conflict even after selecting an alternate port configuration in your jboss-service.xml. To fix this simply select an alternate port (something other than 4446 that is not being used) in cluster-service.xml configuration (obviously not necessary if you are not using the ALL configuration with clustering support). This bug is being fixed in our next release.

I searched in the internet and I tried to change this lines in the hibernate.cfg.xml:
| <!-- JDBC connection properties (begin) ===
| <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
| <property name="hibernate.connection.url">jdbc:hsqldb:mem:jbpm</property>

| === JDBC connection properties (end) -->
|
| <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
|
| <!-- DataSource properties (begin) -->
| <property name="hibernate.connection.datasource">java:/JbpmDS</property>
| <!-- DataSource properties (end) -->
|
But didn't work, the error changed to "Could not find datasource".
Any idea, please??
Thank you!

[JBoss Portal] - Re: JBoss Portal x Liferay Portal x eXo Portal
by thomas.heute＠jboss.com
JBoss Portal doesn't provide applications (such as the blog you mention, blog is a totally independent project of jboss.org btw, you could host your own project on it if you wanted, such as Kosmos portlets which are not developped by JBoss employees).
JBoss Portal provides a framework to build *your* portal. (JBoss is still a middleware division)
We don't expect you to use the default portal that exists on the demo, it's just a way to "show" something. So if you want to provide a better out of the box portal, feel free to contribute but that's not the value we create so little time is spent on this (I know it has an impact for people evaluating our product by just looking at the demo box)
We offer services for portals, such as identity, sso, wsrp, portlet container, theme and layout, user management (talking about API here) and personalization... We also ensure that it scales and work fine in a portal environment.
Our users/customers build their own portlets on top of this framework with technologies such as JSF, Struts, Seam... They usually have strong requirements and will not live with any out of the box forum or blog portlet, they want *their* features, *their* layout...
So since we don't provide applications, we are probably less visible in some area. For large scale developments, we are very visible and competitive but those customers are unfortunately to shy on becoming references :(
That said, we partnered with Alfresco (ECM) and Pentaho, for the application side, more partnership of this kind could happen.
I hope that i was clear enough.
