[Clustering/JBoss] - How does JMS clustering work?
by resh123
Apologize in advance for asking very basic questions, however I am new to JMS/ JBossMQ and trying to understand its intricacies, how it works, etc.
Would like to know how exactly JMS supports clustering. i.e. in a distributed environment, where would the JMS queue reside? How would each node in the cluster communicate with others to send message, receive responses?
From what i read on the internet, I understand that JBossMQ doesnt really support clustering, however JBoss Messaging does. Is this true? Can someone elaborate more on this?
Is there any document on the JBoss Wiki that gives some more information on how exactly the Messaging internals work in JBossMQ/JBoss Messaging? I came across a lot of JMS tutorials that all explain the programatic aspects of JMS,but nothing which explanis actually tells how JMS works. So any document on the internet that give more details about the internals of JMS would be of great help!
Thanks in advance.

[JBoss Portal] - Re: Localizing Tab that has spaces in its name

| You can have display names in the -object.xml descriptor now, we are working on the GUI to let you do it there too.
Manage titles localization inside resource bundles seems to me more natural : this is the role of bundles ! -object.xml files should only be used as technical configuration files, shouldn't they ? This is quite unusual in J2EE : you don't manage portlet title localization or portlet preferences localization in portlet.xml for example !
I'm not bothered by restrictions with object names (like no space character) but by :
- not being able to localize names using their full path, using object hierarchy, .e.g. : PAGENAME_default.page1.subpage1=xxx
- having to define localization outside my webapp

[JBoss Tools (users)] - Re: Problem controlling and deploying to JBoss AS
by rhasselbaum
Thanks, Max, for replying (again)! Ah yes, I do see an error in the event log. It is saying that it failed to deploy because it couldn't copy the WAR file. And when I look at the source path in the error details, it is indeed wrong. It's looking for the file in a subfolder under "<eclipse_workspace_dir>/<project_name>". But, as you and I discussed in a different thread, my project is not rooted under the Eclipse workspace directory, and the project root directory does not equal the project name. So I wonder if this is related to the path problems in JBIDE-1325.
I went back to the WAR archive properties and gave it the explicit filesystem path using the "Filesystem" button (instead of the "Workspace" button). But that didn't fix the problem. It's still trying to copy the WAR from the wrong directory. Should I reopen JBIDE-1325?
Regarding shutting down the server: The communication error says "Failed to connect to server localhost:1099" so I'm pretty sure it is the port number that is wrong. I configured port 1299 by modifying the NamingService bean definition in "conf/jboss-service.xml" and "conf/jboss-minimal.xml".

[JBoss Seam] - outer joins with seam
by jamesjmp
hi,
I wonder if there is a special syntax for defining queries with outer joins in seam.
I am trying this query defined in my components.xml file
| <framework:entity-query name="innerJoinQueryList"
| ejbql="select instruFund, instru, cash
| FROM InstrumentFund instruFund
| left outer JOIN Instrument instru
| ON instruFund.id.idAsset = instru.internalOptionNumber
| left outer JOIN Cash cash
| ON instruFund.id.idAsset = cash.idCash">
| </framework:entity-query>
|
I am using this query from a xhtml file (called RstReportInstruValuList.xhtml ) this way
| <rich:dataTable id="innerJoinQueryList"
| var="innerJoinQueryInfo"
| value="#{innerJoinQueryList.resultList}" >
| <h:column>
| <f:facet name="header">
| <s:link styleClass="columnHeader"
| value="#{messages['instru.securityName']}">
| </s:link>
| </f:facet>
| #{innerJoinQueryInfo.instru.securityName}
| </h:column>
| <h:column>
| <f:facet name="header">
| <s:link styleClass="columnHeader"
| value="#{messages['cash.securityName']}">
| </s:link>
| </f:facet>
| #{innerJoinQueryInfo.cash.securityName}
| </h:column>
| </rich:dataTable>
|
I have this error:
An Error Occurred:
/RstReportInstruValuList.xhtml @157,13 value="#{innerJoinQueryList.resultList}": org.jboss.seam.framework.EntityQuery_$$_javassist_1721
Is there a special syntax for defining queries with joins?
thanks in advance!
