[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by otaylor

When I've contrasted put() and update() I've been using the Hibernate cache terminology put() - cache fill (== putFromExternalRead()) - update - database change (== put()). I don't think a putFromExternalRead() would normally cause a "dirty read", but one possible interpretation of Scott's question was what would happen if you called putFromExternalRead() with data that wasn't yet committed to the database. I don't know why the asynchronous replication of putFailFast() was added orginally, but my assumption is that it's about increasing concurrency and performance. Replicating cache fills synchronously doesn't increase correctness, so you might as well do it synchronously.

[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by steve.ebersole＠jboss.com

Just to clarify my last comment. Keep in mind that putFromExternalRead() always results from the following usage pattern: Object state = readFromCache(); if ( state == null ) { state = readFromExternal(); putIntoCache( state ); } ... In Hibernate terms, readFromExternal is causing the data to get read from the database because it was not found in the cache. That db-read data is always the "truth" in a db-driven app... The only way that data should not overwrite the current node data (putIntoCache) is if suddenly there has been a write lock applied to the node between readFromCache() and putIntoCache() being executed (which is the meaning of my "intention lock" comment).

putFromExternalRead() should *always* over-write anything already there *unless the current data is write locked*. Although that write locked situation (afaict) actually indicates an exception condition.

[JBossCache] - Re: Hibernate/Cache conceptual mismatch

by steve.ebersole＠jboss.com

Owen: (1) What is your deliniation of "put" and "update"? (2) I don't follow how a put could result in a dirty read... Another possibility to consider is an "intention lock" where we temporarily lock a node for the duration of the read/putFromExternalRead cycle. This would guarentee two threads from attempting the same process. This would be instead of #2... So what was the reason for forcing asynch replication? Why not synch? I did not follow where that came in at.

Following up to my last comment: it may work pretty well to have "putFromExternalRead" simply never overwrite existing data.

[Security & JAAS/JBoss] - Re: Problems using JAAS with EJB 3.0 on JBoss 4.0.4-GA

by benm99

I removed the annotation from the bean, reintroduced the xml configuration using the short anme, rather than the full name and it works for me. Thanks a lot for your help.

[JNDI/Naming/Network] - Re: ClassCastException after redeploy

by jaikiran

Where are placing the remote and home interfaces of your beans. Is it in two separate locations(once in war and once in a jar)? If yes, then maintain it at only one place and remove those interfaces from the war. Have a look at: http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingOverview Here's an extract from the same: anonymous wrote : I get ClassCastException | | Assuming it is the same class name, this problem relates to classes getting loaded from different classloaders. At compile time your class has only one identity, its name. If you "deploy" a class many times in different jars, it has multiple identities. They are not the same. See below for more information on the solutions to this problem. | | This can also be caused by you only redeploying part of your application. e.g. a webapp uses an EJB and you only redeploy the EJB. The webapp will still have the old versions of the classes. Also, look at: http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassCastExceptions Specifically, the jmx-console method mentioned over there View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977558#3977558 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3977558

[JBossWS] - noice in SOAP reply

by ge0ffrey

I tried JBoss WS 1.0.3 (patched on a 4.0.4-GA JBoss with a EJB3 profile) with a @WebService annotation on a @Stateless bean. The Stateless bean had a method String sayHello(). When I send a SOAP messages (using WTK 2.2), the reply contained noise (the numbers): <...> 35 <...sayHello/> 7 <...> 0 Any idea what could be causing this?
