Coherence JMX beans for NearCache explanation

Hi there,
can someone explain, what represents mbean how it's seen from JConsole:
Coherence -> Cache -> <Service name> -> <Near Cache name> -> <Node id> -> front -> <some numbers (as I understood its loader ID)>, and how is this possible that 1 of the nodes in cluster has 2 loaders for the same near cache (all other nodes has only 1 loader)
(Coherence:type=Cache,service=DistributedCache3,name=SystemState,nodeId=1,tier=front,loader=22033496 and
Coherence:type=Cache,service=DistributedCache3,name=SystemState,nodeId=1,tier=front,loader=24052850)
We have a cluster of 24 nodes and several caches configured (Coherence 3.4.1). One of the caches is a near cache and the problem I'm trying to investigate is that the local value of one of the entries in this near cache on one of the nodes is differ to backing value and local values on the other nodes.
How this could happen?

Hi lazanik,
The client side constructs such a NearCache are usually scoped by the corresponding class loader. Imagine an application server running two different application that have access to the same cache in a grid. Since the front map of the near cache stores data in the Object format (unlike the backing maps that store data in internal binary representation), it cannot be shared between those two application. The class-loader attribute serves as a scope id to differentiate between those two front tier maps (and corresponding MBeans).

Coherence JMX + Wily

All,
I'm attempting to configure Wily Introscope 8 to record Coherence 3.5 JMX metrics. Coherence runs under WebLogic 9.2.
I have it mostly working the way I want, but for each WebLogic instance in Wily, I see metrics for all Coherence nodes. For example, if I have 3 WL instances in a Coherence cluster, in Wily I see the 3 WL instances. If I drill into each one, I can see the Coherence JMX stats, but I see each of the 3 Coherence nodes listed separately. IOW, server A shows JMX stats for itself and servers B and C. Likewise with servers B and C. I would like to only see server A's stats under the server A node in Wily.
My Coherence JMX settings are like this:
<management-config>
<managed-nodes system-property="tangosol.coherence.management">all</managed-nodes>
<allow-remote-management system-property="tangosol.coherence.management.remote">true</allow-remote-management>
</management-config>
Should I change "all" to "local-only?"
I'd try it myself but it's a hassle to go through the operations team to get this changed.
thanks

Hi John,
I am not familiar with Wiley, but if you want each node to expose only its own mbeans, you would not use the management=all configuration. The management=true would be all you need.

My problem in Weblogic and Message Driven Bean for Topic

Hello to all
I used this page (http://www.ecomputercoach.com/index.php/component/content/article/90-weblogic-jms-queue-setup.html?showall=1)
for setup JMS Server, Queue, Connection Factory on Weblogic Server
and I created a Message Driven Bean ,I used those Queue , and all things was OK
But I wanted to setup a Topic and use it in this manner
I created a Topic like previous steps for setup Queue
(http://www.ecomputercoach.com/index.php/component/content/article/90-weblogic-jms-queue-setup.html?showall=1)
Except in Step 3 ,I selected Topic instead of Queue
then I created a Message Driven Bean in JDeveloper , my Message Driven Bean is like this:
@MessageDriven(mappedName = "jndi.testTopic")
<p>
public class aliJMS1_MessageDrivenEJBBean implements MessageListener {
    public void onMessage(Message message) {
      if(message instanceof TextMessage ){
        TextMessage txtM=(TextMessage) message;
        try{
          System.out.println(txtM.getText());
        }catch(Exception ex){
          ex.printStackTrace();
</p>
When I deploy the Application , Weblogic shows me this error:
+<Aug 30, 2011 11:32:28 AM PDT> <Warning> <EJB> <BEA-010061> <The Message-Driven EJB: aliJMS1_MessageDrivenEJBBean is unable to connect to th+

the JNDI name: jndi.testTopic is not a JMS destination, or the destination found was of the wrong type (Topic or Queue).>
And when I send message to the topic The Message Dirven Bean dosen't work

        return new InitialContext(env);
It's OK and shows messages When I send message to the Topic
Now I want know why the Message Driven Bean doesn't work for those Topic
I want create a Message Driven Bean for Topic in the same way I created for Queue
I don't know what is problem , please advice me
Thanks

Could you try adding a activationconfig to the message-driven bean, for example,
@MessageDriven(mappedName = "jndi.testTopic", activationConfig = {
        @ActivationConfigProperty(propertyName = "destinationName", propertyValue = "jndi.testTopic"),
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic")
public class aliJMS1_MessageDrivenEJBBean implements MessageListener {
    public void onMessage(Message message) {
      if(message instanceof TextMessage ){
        TextMessage txtM=(TextMessage) message;
        try{
          System.out.println(txtM.getText());
        }catch(Exception ex){
          ex.printStackTrace();
}

How to layout beans for single page design

Hey guys. I'm designing a site that uses the Icefaces framework. I've been reading a book called Real World Java EE patterns. I'm kind of confused how to layout the pages. Normally I would have just a POJO class implement serializable for a bean. This bean would then back each page. With a single page design I'm going to have a bunch of elements on the page. Datatables, trees, inputs, calendars etc. Is it normal or best practice to have separate beans for each datatable, calendar, etc or put that all in one bean? I'm not sure how to approach this. Right now each element is a bean and I'm using the @Inject annotation to have the data table talk to the tree and vise versa. This creates really bad code and if I put this as a member of the class I will get a circular reference because the data table bean has to inject the calendar and the calendar has to inject the data table.
Thanks for any help.

'best' practice is to not follow blindly what other people say, but to reason yourself what works best for you. It has been stated many times before and I will state it again: best practice does not exist. Only personal opinions about what is best exist. Personal opinions are not facts.
So choose what works for you. Is the code easy to maintain? Is it readable? Can you perhaps re-use parts of it? Then I'd say you have a winner.
I'll give you my personal favorite. When working with a page that has input elements, I tend to have two or three beans. Replace XXX with a logical and context sensitive name.
XXXForm - this is a simple request scoped bean that has the action and event methods and will hold some data for reading purposes for the view, possibly taken from a database.
XXXStorage - this is a session scoped bean that holds information from the form; if it is an editing function I initialize it with the current state first. Storing this stuff in a session bean makes it very easy to do Ajax stuff and create input cycles that span multiple requests. Also when data is split in multiple pages, the storage class is the one to remember which page is being displayed.
Optionally, I also have an XXXSearch object, which is a session scoped bean that stores search/sort/filter parameters. I make this session scoped so the information is remembered for the duration of the user's visit, meaning he can navigate away from the page in question, come back and all his choices will still be in place.
So no, I don't have beans specifically for each component, although I might make simple POJOs to hold information gathered from several sources (for example, information gathered from several database tables). These beans are generally used to fill the rows of a datatable and are just created from within the form class, for example in a @PostConstruct annotated method.

Creation of CMP bean for a Composite Primary key????

Hi
i am having a composite primary keys in one of my table in the database.
I am trying to create a new entity bean for this table but i don't know how to create one in case when there is a composite primary key for a table.
Can anybody let me know is it possible to do it.
what is the procedure to be followed for the creation of the Entity bean in case of a composite primary key.
I am using MySql as the database .Creating CMP type of Entity bean.
Any help in this regard will be greatly useful to me as this is very urgent.
Thanks & Regards
Vikram K

Hi Nikola,
There are several problems with your CMP bean.
1. Fields of a Primary Key Class must be a subset of CMP fields, so yes, they must be either a primitive or a Serializable type.
2. Sun Application Server does not support Primary Key fields of an arbitrary Serializable type (i.e. those that will be stored
as BLOB in the database), but only primitives, Java wrappers, String, and Date/Time types.
Do you try to use stubs instead of relationships or for some other reason?
If it's the former - look at the CMR fields.
If it's the latter, I suggest to store these fields as regular CMP fields and use some other value as the PK. If you prefer that
the CMP container generates the PK values, use the Unknown
PrimaryKey feature.

What bean for date selection should I choose?

I need bean for date selection with folowing features:
1) Period selection
2) Internatioanization
I foung some components:
1) http://www.java-calendar.com/
(+) supports all need features
(-) 50$ :(
2) http://www.toedter.com/
(+) free, interationalization
(-) no period selection
3) http://sourceforge.net/projects/jdatechooser
(+) free, supports all need features
(-) project is too young, i'm searching more mature project
I have no time for long searches, so advise me component please.

From your own findings it's between 1 and 3, but 3 is "too young" so it looks like 1. Spend the 50.

1.) Please don't double post:Urgent message : oracle9i form builder read txt file error
2.) As for your original post: don't post urgent questions over here. If they are really urgent call oracle support. See How To Ask Questions The Smart Way
and after all:
wcu-015: your form must contain the following bean for this function to be
available : oracle.forms.webutil.file.filefunctions;
are you certain, 100% positive, and absolutely sure you have a bean item with above implementation class in your form? I'd double check that...
JInit and IE8? I am not 100% sure, but I am almost certain that this combination didn't work at all. And please don't tell us you used that stupid hack where you replace the jvm.dll of JInit with one of a current JPI installation.
The Oracle Versions you have in place are rather ancient as well, you really should think about upgrading your database and your forms installation. As you already are on webforms moving to the current version of forms shouldn't require much changes in your forms.
cheers

How to scope beans for a JSF Confirmation Page

I have a web form with corresponding backing bean for each input field. I have two buttons on the form. Here is some of the page:
<h:inputText id="clientName" value="#{clientBean.company}" required="true"/>
<h:inputText id="clientContact" value="#{clientBean.contact}"/>
<h:commandButton id="btn_Submit" value="Submit" action="#clientBean.save}"/>
<h:commandButton id="btn_Cancel" value="Cancel" immediate="true" action="cancel"/>
Navigation rules display a confirmation page with the inputs the user has entered, and the cancel button brings them back to a simple menu screen (where they can click a link and re-visit this web form).
IF THE MANAGED-BEAN-SCOPE for clientBean is set to REQUEST, I cannot use the bean attributes to populate outputText elements on a confirmation page (they are no longer in the current request). (I'm OK with this....)
IF I SET THE MANAGED-BEAN-SCOPE for clientBean to SESSION, I can use the attributes of the managed-bean to drive the confirmation page, HOWEVER... if the user fills in the form and clicks CANCEL, then re-visits the web form, the values they entered prior to clicking Cancel are pre-populated in the web form.
I've even gone as far as to have the Cancel button fire a cancel() method on the clientBean where I set all backing attributes to empty strings. That doesn't work either.
Is there a way I can remove a managed-bean instance from the session scope entirely when the user clicks Cancel? Or is there a preferred method of ensuring that form values make it to the confirmation page using request scoped beans?

I'd the same problem ever.
It's not a good way to do these clear in the cancel button,
for users maybe not click the cancel button, but click others links on the page
and quit, after a while, then goto the form, there will be the previous data
displayed as click back on the confirm page.
at last i resolve the problem by adding a page before the form page.
all links to the form page are linked to the new page,
in the new page,
1st, clear the state of the managed-ben(clientBean),
there were a few ways to do this,
(1), change all the properties of the clientbean to a default value.
(2), remove the clientbean from the session(JSF will create an new instance when it remove from the session)
2nd, redirect the request to the form page.
You may write only one page (the clear-state and forword page) for all form in the application by passing the managed-bean to be cleared as a parameter.
Hope be helpful for you.
