[EJB 3.0] - When NOT to use EXTENDED persistence context?

by lightbulb432

When would you not ever use EXTENDED persistence context in a stateful session bean (which is the only EJB type it can be used in)? To me it seems that the code is cleaner (no unnecessary merge() or whatever) and it only makes sense as a stateful session bean is used to represent conversational state over multiple client calls...by setting an EXTENDED persistence context you recognize that there is a conversation happening. I'm not seeing when you'd not want to use EXTENDED persistence context (I understand it's not the default persistence context). Your thoughts please... Thanks.

[JBoss Seam] - Re: Basic Seam questions

by gavin.king＠jboss.com

1) A Seam persistence context is most like a container-managed extended persistence context. But whereas the container-managed context is tied to an SFSB instance, and hence there can be multiple contexts per conversation, the Seam persistence context has exactly one per conversation. 2) No, you can still use Hibernate Validator, just use an atomic persistence context, and be careful about where you put s:validate(All) 3) persist() does not accept detached entities (it throws an exception).

[Security & JAAS/JBoss] - Re: how to disable password-stacking property

by purna_cherukuri

Hi, I have removed that option in my login-config.xml Now my login-config.xml is like this. <?xml version='1.0'?> | <!DOCTYPE policy PUBLIC | "-//JBoss//DTD JBOSS Security Config 3.0//EN" | "http://www.jboss.org/j2ee/dtd/security_config.dtd"> | <policy> |  | <application-policy name="cms"> | <authentication> | <login-module code="org.apache.jackrabbit.core.security.SimpleLoginModule" flag="required"/> | </authentication> | </application-policy> | | <application-policy name="portal"> | <authentication> | <login-module code="com.tsky.customlogin.CustomLoginModule" flag="required"> | <module-option name="unauthenticatedIdentity">guest</module-option> | <module-option name="userModuleJNDIName">java:/portal/UserModule</module-option> | <module-option name="roleModuleJNDIName">java:/portal/RoleModule</module-option> | <module-option name="additionalRole">Authenticated</module-option> | </login-module> | </authentication> | </application-policy> | </policy> It is still caching the username and passwords. I want it to go to CustomLoginModule each time. Can anyone help me out in this?

[JBossCache] - Re: How to use JBossCache within WebSphere?

by lakida

Are there any instructions for configuring Hibernate with Jbosscache and websphere with CMT. The instructions on the WIKI are helpful only to a certain extent. I am trying to configure hibernate 3.x with Websphere 6.0 CMT and Jbosscache as transactional and clusterable cache. I am running into issues and the help on this particular topic is minimal. I can post the stack trace and configuration files if someone can helpout.

[JBoss Seam] - Re: Basic Seam questions

by lightbulb432

Some questions below: 1) Could somebody describe the difference between the Seam-Managed Persistence Context that I've been reading about and the regular persistence contexts (Transaction and Extended)? Which one is it more similar to, and what should a Seam user know about it? 2) If you have an entity whose fields you populate over several steps in a conversation, business process, or just a session, would you need to avoid validation annotations like @NotNull? I tried it and, after the first step in the multi-step process, it expectedly says that you're violating a null condition (because you've entered only a few fields and not all). Is there any way to get around this, short of moving everything to a single page or getting rid of annotations...or is this just a downside of such multi-step processes? 3) If you have an existing entity that is detached, what's the difference between calling EntityManager.persist and EntityManager.merge? Is persist simply not meant to be used in such a case (though couldn't it find the current existing row in the database using the primary key of the Java entity and update that row based on changes)?

[JCA/JBoss] - Re: How to set Isolation Level in EJB 3.0 (CMP)

by weston.price＠jboss.com

The only way to effectively do this would be to set the <transaction-isolation></transaction-isolation> property in your *-ds.xml file. Unfortunately, this will be applicable to *all* connections used/created by EJB3 that use that datasource. EJB3 provides no way to acquire the underlying connection used by the EntityManager and as a result you will not be able to set this property dynamically.

[EJB 3.0] - Validation annotations

by lightbulb432

Should @NotNull or should @NotEmpty be used for strings that you want to make sure the user enters a value for? Is either the same as saying @Length(min=1)? With all the validation annotations, I know you can have them on the entity class. However, I tried putting them on the getter methods on the session bean interfaces (for methods on the bean that are bound to form fields), but it doesn't seem to do anything. Can you have these annotations on the session bean at all? (I imagine it would be possible because that's where you'd want to validate what the user is entering, right?) Thanks.
