[JBoss Seam] - Problem deploying jpa example to Weblogic 9.2
by barthjj
I'm following the readme in the jpa example for Seam 2 Beta. After deploying the war, I attempt to start the application. I get these exceptions in the log file:
javax.persistence.PersistenceException: [PersistenceUnit: bookingDatabase] class or package not found
at org.hibernate.ejb.Ejb3Configuration.addNamedAnnotatedClasses(Ejb3Configuration.java:1089)

Any help on this? Unfortunetly, I'm new to both Seam and Weblogic.
Thanks,

[EJB 3.0] - [Bug?] Composite Primary key as Foreign Key in other entity
by Bouma
Hi all,
I've been struggling with a problem the past few days, and even though i found a 'solution' for the problem, i think i may have found a bug in JBoss 4.2.0. FYI, i'm using MySQL 5.0 as DB. I've been trying the following:
The Setup
I have a database with ContentItems which are available for certain Brands and for certain Countries. We want to display a Top 5 or 10 or whatever of these ContentItems on our website, which is where the problems began to arrise. I'm trying to model the following:
TopX
--------
brand_id <PK,FK> -------> FK to Brand entity
country_code <PK,FK> ------> FK to Country entity
content_type_id <PK,FK> -------> FK to ContentType entity
TopXContent
------------------
brand_id <PK,FK> -------> FK to TopX entity PK
country_code <PK,FK> ------> FK to TopX entity PK
content_type_id <PK,FK> -------> FK to TopX entity PK
content_item_id <PK,FK> -------> FK to ContentItem entity
position <>
So, the TopX is the parent entity in this story, with a composite PK, composed of 3 Foreign Keys to 3 different entities.
The TopXContent is the child class with a composite PK, composed of a foreigen key to TopX (so that foreign key has 3 columns in it) and one FK to ContentItem.
Consider the following entities:
TopX Entity
| @Entity
| @Table(name = "top_x", catalog = "content_module", uniqueConstraints = {})
| public class TopX implements java.io.Serializable
| {
| private TopXId id;
| private Brand brand;
| private ContentType contentType;
| private Country country;

| public TopXId getId()
| {

The Problem
When i deploy this, Jboss will try to generate the tables (because I configured it to do so, it's handy :)), but it fails on the generation of the foreign key from TopXContents to TopX. I get a MySQL errno: 150, saying it can't create a table with some weird name (error 150 = malformed foreign key). When i look at the query it tries to run i see the following:
| alter table content_module.top_x_content
| add index FK7A0FB9482B69DB27 (brand_id, country_code, content_type_id),
| add constraint FK7A0FB9482B69DB27
| foreign key (brand_id, country_code, content_type_id)
| references content_module.top_x (country_code, content_type_id, brand_id);
|
After looking at it for a while i notice the order of the columns is different in the foreign key declaration:
| brand_id, country_code, content_type_id
| country_code, content_type_id, brand_id
|
If place the second brand_id as the first colum in the 'references' clause, the query works just fine... So i do this, redeploy, and JBoss remains quiet. But! when i try to use the entities, the TopX is retrieved just fine, but the TopXContents collection is returned empty! Even though the database is filled in correctly (i tested with a SQL query directly on MySQL).
I look at the debug log again, and it shows that JBoss is making the same mistake it made when it tried to apply the foreign key! The columns are all messed up! When it tries to join the TopX and TopXContent tables, it matches brand_id=country_code, country_code=content_type_id and content_type_id=brand_id. CHAOS!
So i started my search on the internet.. nothing... i started making desperate attempts to find a workaround... SUCCES!
I, quite simply, changed the JoinColumns in the TopXContents entity above the getTopX() function from
| @JoinColumns( { @JoinColumn(name = "brand_id", unique = false, nullable = false, insertable = false, updatable = false), @JoinColumn(name = "country_code", unique = false, nullable = false, insertable = false, updatable = false), @JoinColumn(name = "content_type_id", unique = false, nullable = false, insertable = false, updatable = false) })
|
to
| @JoinColumns( { @JoinColumn(name = "country_code", unique = false, nullable = false, insertable = false, updatable = false), @JoinColumn(name = "content_type_id", unique = false, nullable = false, insertable = false, updatable = false), @JoinColumn(name = "brand_id", unique = false, nullable = false, insertable = false, updatable = false) })
|
So, i put the brand_id column at the end instead of the beginning of the @JoinColumns! And tadaaaammm! It works! The DB is generated as it should, queries work, life is good again!
Sooo...
Is this a bug? Or am i just trying something stupid? I got it working though ^_^. Thanks for your time...

[Security & JAAS/JBoss] - Jboss AS 4.2 + JBoss Federated SSO problem
by margielm
Hi all!
I am currently trying to use JBoss Federated SSO with jboss 4.2 and I am dealing with big problem on which I can't find answer anywhere.
I have started jboss-sso-test.ear on AS 4.2 but after logging in I've got this exception on my console:
15:28:30,788 ERROR [SSOAutoLogout] org.jboss.security.valve.SSOAutoLogout[/test]
javax.servlet.ServletException: org.jboss.security.saml.SSOException: org.xml.sax.SAXParseException: XML document structures must start and end within the same entity.
at org.jboss.security.valve.SSOAutoLogin.invoke(SSOAutoLogin.java:183)
at org.jboss.security.valve.SSOTokenManager.invoke(SSOTokenManager.java:125)
at org.jboss.security.valve.SSOAutoLogout.invoke(SSOAutoLogout.java:172)
at org.jboss.security.valve.SSOFederationRouter.invoke(SSOFederationRouter.java:135)
and so on...
After some research on Google, I've found the answer: this is the problem of tomcat-util.jar version in jbossweb-tomcat55.sar folder.
And here is the moment where big problem starts - I am using jboss 4.2 - and there is NO jbossweb-tomcat55.sar in this version - instead there is
jboss-web.deployer folder. But again... there is NO tomcat-util.jar in it (and furthermore there is no patch for 4.2 in JBoss SSO CR1 distribution).
I don't have any more ideas. Is there any ways to run JBoss SSO on 4.2? If yes what is the solution?
Thanks!!
Best Regards
Michal Margiel
