[JBoss Seam] - Wiki entry: SeamEntityHomeForLongRunningContexts

by baz

Hello, i want to give some thougts about this wiki entry http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityHomeForLongRunningCont... I am using this approach since seam supports it. And i am not quite sure, but for me Peter is one of the initiator of this idea? One question: currentUserId is never changed, so the @Out has only the effect to transfer currentUserId to session scope? So you can set currentUserId in any scope and after accessing currentUser you will find the currentUserId automatically bound to session scope. But nothing hinders you to set the currentUserId directly in session scope. If you do this, it is possible to achieve the same by configuration in components.xml. <factory name="currentUser" value="#{currentUserHome.instance}"/> | <framework:hibernate-entity-home name="currentUserHome" entity-class="class.for.User"> | <framework:id>#{currentUserId}</framework:id> | </framework:hibernate-entity-home> This behaves exactly the same as Peters example in the wiki,iff you set currentUserId in the correct scope(here session). This works with seam1.1.6 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021021#4021021 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4021021

[JBoss Seam] - Re: DataModelSelection property not set after using the back

by mjek2

You call updateListItems() from setCurrentObject() which in turn is called when the user selects something from the list using s:link. If updateListItems() manipulates mainListItems I can imagine that it could cause your problem. Did you try to remove updateListItems() from setCurrentObject()? And do you observe your problem only when using back button?

[Clustering/JBoss] - Re: Pooling in Buddy Replication

by ＠jb0ss

Thanks Manik for your response! But I could not find this happening in my case. Let me explain Now my scenario is that - I have four nodes on my machine (four multiple instances on my machine) node1 and node2 --> pool1 node3 and node4 --> pool2 C:\jboss-4.0.5.GA\server\node4\deploy\tc5-cluster.sar\META-INF\jboss-service.xml -- This is the file which I changed I deployed the application war on all the nodes. I have Apache+mod_jk configured for my jboss. I am calling my application now in the browser. http://localhost/OnlineShopping - I click on submit to log in It gives me a URL like this http://localhost/OnlineShopping/login.do;jsessionid=wdlhqzxNG1lDE56xWLSza... And I assume that my request was served by node2 Now I stop node2 after doing some shopping and there is data in the session APP is working fine here. Now I stop node1 APP is working fine -- But Application has not failed because node1 and node2 were from pool1. It seems here that application has data backed up on node3 and node4 (which are from pool2) because when I stop now node3 My Application is still running fine. I can continue shopping and data is successfully retrievable from session and so on It does not FAIL. Now I don't understand why it does not fail? What is the meaning of pool-names here by naming pool1 for node1 and node2 and pool2 for node3 and node4. Can you please explain/suggest more?

by gavin.king＠jboss.com

Please report this in JIRA, I guess it should be "isDeleted()". View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021013#4021013 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4021013

[JBoss Seam] - Re: could not execute seam commands.

by gavin.king＠jboss.com

You have to build seam first. Just type "ant" in the main dir. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021012#4021012 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4021012

[Installation, Configuration & Deployment] - Re: Deployment Problems on Linux

by Torgue

For example, i have two different versions of the CGLIB library in my Webapp. Thats not correct, i know. When the wrong version is loaded, a "CGLIB enhancement failed" exception is throws. On windows or debian no exception is throws, but when i deply the war file on Suse the exception is thrown. The installation is absolutely identical. Yes, i could could delete the wrong library version, but there seem to be more problems which don't throw an exception. So the question is, why doesn't the installation on Suse behave like the installation on Windows or Debian?

[EJB 3.0] - Composite Key is made up by foreign keys

by mrchit_2000

Hi all, I have problem finding out how to specify the member of the composite key are foreign keys pointing to primary key of other tables. For example, If my composite key have 2 columns (A,B). I created wrapper like public final class CompKey implements Serializable { private int A; private int B; public boolean equals(Object obj) { .............. } public int hashcode() { ........... } } Then in my class I will use @IdClass(CompKey.class) @Entity public class MyClass implements Serializable{ private int A; private int B; } But now I want to specify A and B as foreign keys, how do I do that? I tried using @JoinColumn and add 2 more fields to class MyClass but that gives me error saying the column names A and B are repeated. Can someone tell me how to specify A and B as foreign key but can still use them as composite key at the same time? Thank you very much in advance, Lngo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021009#4021009 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4021009

[JBoss Messaging] - Re: Does HA-JNDI provides load balancing ?

by ovidiu.feodorov＠jboss.com

JBM 1.0.x series doesn't support clustering. You might want to try 1.2.x. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021008#4021008 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4021008

[JBoss Messaging] - Does HA-JNDI provides load balancing ?

by sathish_06

Hi, We tried to setup JBoss clustering/HA-JNDI for JBoss Messaging system, but observed that it provide failovers but not Load balancing. Version details : Jboss 4.0.4 AS, Jboss Messaging 1.0.1.SP4 Summary: We setup two instance of Jboss messaging system with HA-JNDI enabled. There is one publisher(standalone java application) where we configured JNDI provide url as java.naming.provide.url=jbossinstance1:1100, jbossinstance2:1100. We observed that when we publish lots of msgs, then all msgs goes to one jboss messaging instant, and not even single msg goes to other instance. But, when we stopped messaging instance where all msgs arrives, producer starts sending msgs to the second jboss messaging instance, without any kind of interruption in the producer application. So, we found that its provides failovers, but not load balancing. We referred the information found in the url for setting up HA-JNDI: http://docs.jboss.org/jbossas/jboss4guide/r4/html/cluster.chapt.html The information also says that load balancing also supports in JNDI clustering, which is not happening in our setup. But, we are aware that Jboss messaging 1.0.1.SP4 doesn't support clustering, but 1.2 start supporting clustering mechanism. Clarification : 1) Doest HA-JNDI with Jboss 4.0.4 AS & jboss messaging 1.0.1.SP4 supports load balancing ? If yes can you pls help us in directing to the right information where we can find the setup details. 2) If HA-JNDI with jboss messagins 1.0.1 version doesn?t support load balancing, will jboss messaging 1.2, which has clustering feature supports both failovers & load balancing ?
