[JBoss-user] RE: Using CMR with PK-Field as FK
It appears these CMR access and foreign key constraint issues can be resolved in a specficiation compliant and portable manner by implementing the INSERT after ejbPostCreate returns. As it stands we have to change our schema to defer referential integrity checks until we commit. Those building J2EE applications on top of legacy database structures (perhaps a significant percentage) will find that a difficult sell in production environments with existing applications already in place. The lack of a deferred insert may also require code changes when porting from weblogic - at least - to support this difference in behavior. The approach taken by weblogic (deferred inserts) appear to have significant merits. --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] Standalone Tomcat 4.1 and JAAS
Thanks for the response, sorry for the delay in digesting this... It seems like the AuthenticationManager and RealmManager interfaces don't have any particularly sensitive methods related to them, so my guess is the only reason that these aren't already available remotely is because they are different per web application? Correct me if I am wrong, but this solution seems like it would only support one login context per JNDI tree. If that's the case, one option would be to parameterize the instantiation of JBossSecurityMgrRealm with the name of a java:comp/env/security subcontext to use. This would solve this issue, but are working patches of this nature something that you would consider applying or is this a misguided hack? happy ny! -b > -Original Message- > From: Scott M Stark [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, December 18, 2002 9:24 PM > To: [EMAIL PROTECTED] > Subject: Re: [JBoss-user] Standalone Tomcat 4.1 and JAAS > > > The ClientLoginModule is just a wrapper around the > SecurityAssociation thread > local variable accessors and the JBossSecurityMgrRealm uses > this directly.

Re: [JBoss-user] Re: Using CMR with PK-Field as FK
Alex,
Let me repeat what I think happens during entity bean creation:
In ejbCreate we set all primary key fields.
In ejbPostCreate we can set up any CMR fields.
Any CMR fields set in ejbCreate are ignored, and must be set again in
ejbPostCreate.
Now if we have a table, T1, with PK = {pkCol1, pkCol2}, and pkCol1 acts
as a foreign key to another table, T2, then our entity bean will have a
problem, because the field mapped to pkCol1 will also be marked as a CMR
field, and so it will be blanked out at the end of ejbCreate (actually
throws the IllegalStateException seen below).
So, can we instead only nullify CMR fields that are not mapped to primary
key fields. This should work fine if T1-T2 is many to one or one to one
relationship. Many to many is not a problem in this case because we are
using foreign key constraints and not a mapping table to implement the
relationship.
So, in Frank's example, he sets up the two parts of the primary key in
ejbCreate, and does nothing in ejbPostCreate. He can use his CMR getter no
problem. Of course, the CMR setter would throw an exception as you can't
change the primary key.
Have I missed anything?
Happy New Year,
Jonathan

LF> So my Question is: How to add a FeatureOption to Feature ?
This is the expected behaviour.
In this case, the relationships are assigned between ejbCreate and
ejbPostCreate.
Having the same values in pk field and the corresponding fk field
means having a relationship.
Any attempt to modify the relationship with CMR accessors or
with collection api will throw this exception.
The relationship is removed only with one of the participant removal.
Do you think it should work other way?

Re: [JBoss-user] How to INSERT after ebjPostCreate versus ejbCreate
Dain, I did a hunt on google for any problems, and the only thing I found was this: www.geocities.com/lydian_third/ admintips/pkconstraint.pdf Basically it seems that unique indexes may cause a problem with deferrable constraints. However, I think the way we use the deferrable fk constraint, then it should be OK.
