[EJB 3.0] - Entity Bean Package Modification (javax.persistence.Persiste
by repkin
Hi,
I have changed Entity bean package to another, but jboss server is still looking for for old package and giving "class or package not found" exception.
I have changed com.atosorigin.utils.pojo.PrStaff to com.atosorigin.utils.ejb.PrStaff, but server is still searching for old package.

[JBoss Messaging] - Messages distribution across cluster.
by fl_
Hello,
We are thinking about switching from JBossMQ to JBossMessaging. I have read user guide for JBM 1.4.0 SP3 and few messages on forum but I think I still need clarification about how messages are distributed across nodes in cluster configuration. I read a following topic but still don't know if I understand everything correctly.
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=133762&postdays=...
We have three application servers, called AS1, AS2, and AS3. Our application is assembled from:
Producer A (singleton) - deployed only on AS1
Queue A (clustered)
Consumer A - deployed on all nodes
Producer B - deployed on all nodes
Queue B (clustered)
Consumer B - deployed on all nodes
Deployment and messages flow:
| (AS1) Producer A ---> Queue A ---> Consumer A/Producer B ---> Queue B ---> Consumer B
| (AS2) Queue A ---> Consumer A/Producer B ---> Queue B ---> Consumer B
| (AS3) Queue A ---> Consumer A/Producer B ---> Queue B ---> Consumer B
|
As you can guess, I wish that load related with queue A will be balanced across cluster. If I understand correctly, if non-loadBalanced ConnectionFactory will be used in Producer A only Consumer A on AS1 will be used to handle whole load, right? (according to the rule: 'local consumer is preferred')
Have it got any matter how many elements will be in queueA? Is there any starvation-protecting mechanism which will sends part of messages across cluster if 'number of messages' or 'time in queue' exceed some limit?
In other words, is there any situation where rule: 'local consumer is preferred' will be ignored.
If I understand correctly the best I can do is to use loadBalanced ConnectionFactory in Producer A. Then different connections created via this ConnectionFactory will be attached to various nodes. Then load will be balanced. Am I right?
Second issue is about rule: 'local consumer is preffered'. If I understand correctly in cluster configuration every node has its own 'local queue' for every queue.
In fact it may be very useful feature for us, if part of the flow stay on one node. It means behavior where: Consumer A on AS2 gets a message, process it and send new message to queue B (via Producer B on the same node: AS2), then Consumer B on the same node (AS2) will be used to process this message. So part of the flow: 'Consumer A/Producer B ---> Consumer B' will be processed on the same node.
If I understand correctly this will happen if non-loadBalanced ConnectionFactory will be used in Consumer A, Producer B and Consumer B, right?
Will it be ok, if Producer A sends message via loadBalanced ConnectionFactory to QueueA and Consumer A use non-loadBalanced ConnectionFactory to consume such message?
Most important question in this approach is about failover. Lets say that there is processing and all queues (especially QueueB) keeps messages (each node has its own messages in its own 'local queue') and then, lets say, AS2 go down. Will messages related with AS2 be seamless distributed to other nodes?
Best regards.

[JBoss Portal] - Re: Why /portal/portal/myPortal ?
by julien＠jboss.com
the second portal comes from the PortalObjectURLFactory and PortalObjectCommandFactory that are mapped to handle URL mapping of portal objects (pages, windows, etc...) to URLs.
for instance, /portal/portal/default/default can be decomposed into
/portal + /portal + /default/default
which means
- /portal = context path of portal war file
- /portal = mapping of the PortalObject command&url factories
- /default/default = mapping of ViewPortalObjectCommand with id=/default/default
all of this is totally flexible and could be adapted to your needs.
I made the mistake to have a "/portal/portal" in order to remove ambiguity with CMS content which is under "/portal/content". I could have use "/" as portal object root and use a notion of shadowing (i.e "/content" would present CMS content and shadow a "/content" virtual portal) and I should have done that.
We are keeping that setting as default behavior until now for backward compatibility.
With the presentation framework there will be a new mapping of URLs to portal invocations so it is an opportunity to fix that in 2.8.

[JBoss Cache: Core Edition] - Re: Clustered and JDBCCacheLoader access to DB

[JBoss Tools (users)] - Generating entities problem with equals method in id class
by elvisd
hi all,
i have a problem with jboss tools (nigthly JBossTools-200806211803-nightly-ALL-linux-gtk) and eclipse canymede 3.4RC4.
i have created an application via terminal using seam-gen and so on, following instructions in getting started.
Then i'd like to generate my entities from my existing db (MS SQL 2005, connecting through MS jdbc driver)
tables are correctly loaded and beans are generated.
when a table has a composite Id (i.ex. table Account, ID cols are IDAccount and IDCompany) the composite id class is generated (AccountID) and embedded with annotations.
But in the equals method there are errors that i ignore how to fix them:
Class AccountGroupId.java
| public boolean equals(Object other) {
| if ((this == other)) // *1
| return true;
| if ((other == null))
| return false;
| if (!(other instanceof AccountGroupId)) //*2
| return false;
| AccountGroupId castOther = (AccountGroupId) other; //*3
|
| return ((this.getIdgroup() == castOther.getIdgroup()) || (this
| .getIdgroup() != null
| && castOther.getIdgroup() != null && this.getIdgroup().equals(
| castOther.getIdgroup())))
| && ((this.getIdCompany() == castOther.getIdCompany()) || (this
| .getIdCompany() != null
| && castOther.getIdCompany() != null && this
| .getIdCompany().equals(castOther.getIdCompany())));
| }
|
*1: Incompatible operand types AccountGroupId and Object
*2: Incompatible conditional operand types Object and AccountGroupId
*3: Cannot cast from Object to AccountGroupId
Any Composite Id class has this three errors... any thoughts?
Kindly
elvisd
