No Beans listening for name "xyz" registered for XMIIIDOC01 on system

Hi
I am getting the error "no beans listening" in ECC and also in MII. What could be the error?
Thanks for your help.

Arnaud,
I did find one issue for the note so I asked that it be modfied. It should be out in a day or two. Here is what it stated for the particular issue I ran into above.
Clear chache by calling following url on MII instance

Huge performance differences between a map listener for a key and filter

Hi all,
I wanted to test different kind of map listener available in Coherence 3.3.1 as I would like to use it as an event bus. The result was that I found huge performance differences between them. In my use case, I have data which are time stamped so the full key of the data is the key which identifies its type and the time stamp. Unfortunately, when I had my map listener to the cache, I only know the type id but not the time stamp, thus I cannot add a listener for a key but for a filter which will test the value of the type id. When I launch my test, I got terrible performance results then I tried a listener for a key which gave me much better results but in my case I cannot use it.
Here are my results with a Dual Core of 2.13 GHz
1) Map Listener for a Filter
a) No Index

Hi Robert,
Indeed, only the Filter.evaluate(Object obj)
method is invoked, but the object passed to it is a
MapEvent.<< In fact, I do not need to implement EntryFilter to
get a MapEvent, I could get the same result (in my
last message) by writting
cache.addMapListener(listener, filter,
true)instead of
cache.addMapListener(listener, new
MapEventFilter(filter) filter, true)
I believe, when the MapEventFilter delegates to your filter it always passes a value object to your filter (old or new), meaning a value will be deserialized.
If you instead used your own filter, you could avoid deserializing the value which usually is much larger, and go to only the key object. This would of course only be noticeable if you indeed used a much heavier cached value class.
The hashCode() and equals() does not matter on
the filter class<< I'm not so sure since I noticed that these methods
were implemented in the EqualsFilter class, that they
are called at runtime and that the performance
results are better when you add them
That interests me... In what circumstances did you see them invoked? On the storage node before sending an event, or upon registering a filtered listener?
If the second, then I guess the listeners are stored in a hash-based map of collections keyed by a filter, and indeed that might be relevant as in that case it will cause less passes on the filter for multiple listeners with an equalling filter.
DataOutput.writeInt(int) writes 4 bytes.
ExternalizableHelper.writeInt(DataOutput, int) writes
1-5 bytes (or 1-6?), with numbers with small absolute
values consuming less bytes.Similar differences exist
for the long type as well, but your stamp attribute
probably will be a large number...<< I tried it but in my use case, I got the same
results. I guess that it must be interesting, if I
serialiaze/deserialiaze many more objects.
Also, if Coherence serializes an
ExternalizableLite object, it writes out its
class-name (except if it is a Coherence XmlBean). If
you define your key as an XmlBean, and add your class
into the classname cache configuration in
ExternalizableHelper.xml, then instead of the
classname, only an int will be written. This way you
can spare a large percentage of bandwidth consumed by
transferring your key instance as it has only a small
number of attributes. For the value object, it might
or might not be so relevant, considering that it will
probably contain many more attributes. However, in
case of a lite event, the value is not transferred at
all.<< I tried it too and in my use case, I noticed that
we get objects nearly twice lighter than an
ExternalizableLite object but it's slower to get
them. But it is very intersting to keep in mind, if
we would like to reduce the network traffic.
Yes, these are minor differences at the moment.
As for the performance of XMLBean, it is a hack, but you might try overriding the readExternal/writeExternal method with your own usual ExternalizableLite implementation stuff. That way you get the advantages of the xmlbean classname cache, and avoid its reflection-based operation, at the cost of having to extend XMLBean.
Also, sooner or later the TCMP protocol and the distributed cache storages will also support using PortableObject as a transmission format, which enables using your own classname resolution and allow you to omit the classname from your objects. Unfortunately, I don't know when it will be implemented.
>
But finally, I guess that I found the best solution
for my specific use case which is to use a map
listener for a key which has no time stamp, but since
the time stamp is never null, I had just to check
properly the time stamp in the equals method.
I would still recommend to use a separate key class, use a custom filter which accesses only the key and not the value, and if possible register a lite listener instead of a heavy one. Try it with a much heavier cached value class where the differences are more pronounced.
Best regards,
Robert

Managed Bean Help for Definition Help

I am working on creating Managed Bean Help for Definition Help as described in ‘19.5.3 How to Create Managed Bean Help’ section of the Web User Interface Developer's Guide fpr ADF. Using JDev Version 11.1.2.1.0.
Thought I had all the artifacts assembled but when I run the log message is: <ELHelpProvider> <_getTranslationMap> ELHelpProvider's helpSourceExpression is null.
Any suggestions would be greatly appreciated.
Here is the managed bean:
public class ELHelpProviderProjRequest extends ELHelpProvider {
    public ELHelpProviderProjRequest() {
    /* To use the HelpProvider, the EL expression in the helpTopicId attribute must point to a Map, otherwise
       * you will get a coerceToType error. */
    public Map<String, String> getHelpMap()
          Iterator iterator = _HELP_MAP.entrySet().iterator();
          while(iterator. hasNext()){
          System.out.println("hash map entry " + iterator.next());
        return _HELP_MAP;
    static private final Map<String, String> _HELP_MAP = new HashMap<String, String>();
        static {
          // each element [put] can be for a separate helpTopicId attribute
          _HELP_MAP.put("MAPHELP_CATEGORY_CAPITAL_DEFINITION", "Map value for credit card definition");
          _HELP_MAP.put("MAPHELP_CATEGORY_OTHER_DEFINITION", "Map value for credit card instructions");

Disclosure Listener for PanelTabbed

Hi All
<<Jdeveloper 11.1.2.3.>>
I have a paneltabbed component with 5 tabs (show detail item). My scenario is Every-time user clicks on a tab I need to perform same set of tasks (like refreshing the VO to check for new data).
Only If the user selects Tab3 then the logic executed is different.
What is the best of achieving this.
Do I need to write a disclosure listener for every single tab or I can have a same disclosure listener for 4 tabs which does same action and one other disclosure listener for Tab3.
Kindly guide me with the correct approach.
regards,
bnkr

Hi,
Here is the sample code with only one disclosure event for all tabs with condition inside to check which tag is disclosed:
<af:panelTabbed id="pt1">
<af:showDetailItem text="Tab 1" id="sdi1"
     disclosureListener="#{<Bean>.tabDisclosed}">
    <af:outputText value="Tab 1 Contents" id="ot1"/>
    <af:clientAttribute name="disclosedTab" value="Tab1"/>
</af:showDetailItem>
<af:showDetailItem text="Tab 2" id="sdi2"
     disclosureListener="#{<Bean>.tabDisclosed}">
    <af:outputText value="Tab 2 Contents" id="ot2"/>
    <af:clientAttribute name="disclosedTab" value="Tab2"/>
</af:showDetailItem>
<af:showDetailItem text="Tab 3" id="sdi3"
     disclosureListener="#{<Bean>.tabDisclosed}">
    <af:outputText value="Tab 3 Contents" id="ot3"/>
    <af:clientAttribute name="disclosedTab" value="Tab3"/>
</af:showDetailItem>
</af:panelTabbed>
// Bean Code
    public void tabDisclosed(DisclosureEvent disclosureEvent){
        if (disclosureEvent.isExpanded() == true) {
            if(disclosureEvent.getComponent().getAttributes().get("disclosedTab").equals("Tab3")){
                //TODO Code when Tab 3 is disclosed
            }else{
                //TODO Code for other tabs
Note that af:clientAttribute is set for each showDetailItem where we pass the value for disclosedTab attribute to identify which tab is disclosed

"Could not locate the bean with the ejb-name XYZ in weblogic-ejb-jar.xml

Hi,
Please someone help me on this...
I'm trying to deploy an application on WLS 8.1 SP4
on HPUX IA64 arch. From the ear file WLS is able to
deploy 3 jars but for the last two jars it's throwing
the below error:
Could not locate the bean with the ejb-name xyz in weblogic-ejb-jar.xml
But ejb with name xyz is defined in the the weblogic-ejb-jar.xml file and it's also present in the
META-INF/ejb-jar.xml file.
I have no clue what's going wrong.
Any help is appreciated.
Thanks
Mouli

oops! Pls ignore my previous mail. It was for a different problem.
FOr the original problem of "couldn ot locate the bean with the ejb-name XZY in weblogic-ejb-jar.xml":
This happens if you don't have the below files defined
for a JAR/EAR file:
weblogic-ejb-jar.xml and weblogic-cmp-rdbms-jar.xml (needed if you have any Datasource mapped)
These two are basic files required for any JAR/EAR file.
If you dont' have it already you can generate them using
$WLS_HOME/bin/startWLBuilder.sh GUI tool bundled along
with WLS (I used 8.1 SP4) to generate these files ! This tool is really helpful.

Listening for several input queues

Hi!
My application receives messages from several queues. I also need to know for each message what queue is it from. That's why I had to define separate MessageListener's for each queue. So each queue has its instance of MyListener (see below). I synchronized the onMessage method on static Object, so only one message from all queues is processed in given moment:
MyListener implements MessageListener
static Object object;
onMessage (Message message)
synchronized (object)
//process
The problem is, that while processing current message, new messages (I suppose one per queue) are already taken from the queue and waiting to be processed. Thus if my application will shut down I will loose at least one message per queue. I'd like to hear your suggestions.
Thanks.

Rather than creating multiple listeners, you can write one listener with a case like structure:
public void onMessage(Message m) {
Queue queue = (Queue) m.getJMSDestination();
String name = queue.getName();
if (name.equals("q1")) {
// what the message listener for q1 would do ...
} else if (name.equals("q2")) {
// etc
You can then register this message listener for multiple queues. The motivation for doing this was a requirement that the execution of the message listeners had to be serialized. You can also achieve this by creating the queue receivers from the same session.
If there is no serialization requirement it's a matter of taste whether you prefer the combo listener above or multiple listeners. In this case you also can create the sessions from different connections to get concurrent message dispatch and possibly better performance.

How to configure multiple listeners to listen for the same instance.

Hello everyone,
I am running oracle database 11g and I want information regarding how to configure multiple listeners to listen for the same database instance. Actually I know how to configure more than one listener but the main thing that I am confused about is when we create listener.ora file, do we have to statically register the database instance with both the listeners or the instance will register itself with both the listeners.
According to my knowledge the instance will register with the listener specified by LOCAL_LISTENER parameter and we cannot have more than one value for this parameter.
Please only give detailed answers with example as I am tired of simple answers with details that I already know.

Hello,
Yes, it can make sense to have several listener for one Oracle instance. For instance you may have one listener for the applications another listener for DBA administration tasks as well as one listener dedicated to dataguard broker. It is not possible to have several listeners listening on the same IP and Port.
By default the database try to automatically register to a listener on port 1521. To instruct the instance to register to a specifc list of listeners you can add in the init.ora the local_listener parameter with an alias definition:
i.e
local_listener=MY_SET_OFF_LISTENERS
in your tnsname.ora add an entry called:
MY_SET_OFF_LISTENERS_LOCAL= (ADDRESS_LIST=
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1530))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1531))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1532))
In this sample your instance will register to three listeners listening on respectively port 1530, 1531 and 1532
If you want your clients can be balanced over the 3 listeners

How do I listen for changes in a container's components?

I have a JScrollPane that contains a JTextPane. I want any Container that can possibly contain my JScrollPane to be able to listen for changes in the JTextPane's Document.
For example, at the moment I'm using a JTabbedPane to hold a number of my JScrollPanes and I want to alter the tab title when any associated JScrollPane-JTextPane-Document is updated.
Any suggestions on how best to handle this?

I would use a controller object that manages all your gui components (tabs, scrolls, documents, text panes). Your controller object can register as a listener to the appropriate component, and when it changes, update the title of a tab (or do whatever else) as appropriate.
Never put business logic like this stuff inside the actual gui components. Create, layout, etc. all the gui components (and related components like Document) from another controller like object instead. It makes handling the various listener stuff like this much easier. Read up on MVC (model view controller) stuff for more info.
As for the actual mechanics, you could get the document that is used in the JTextPane and register as a DocumentListener. As a document listener, you get notified of all changes that are made to that document.

On starting WebLogic getting Error : Listening for transport dt_socket at address: 8453 Exception in thread "main" java.lang.NoClassDefFoundError: vXmx512m

Hi,
system i am using for Oracle SOA is :
Windows 64 Bit
i5 Processor
6 GB RAM
29 GB on C Drive is already free after installation of all SOA related products.
I have installed wlserver_10.3 for SOA 11g Development purpose and followed exact installation sequence and procedure as mention in oracle documentation
i created domain also and every thing look correct but after installation procedure there are "Additional actions required just after every thing installed" :
setting memory limit
starting weblogic server (Admin Server)
starting weblogic managed server
and so on
now Problem is when i execute C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin startWebLogic.cmd
as mention in oracle documentation i am getting following error message : (i have only included last error lines instead of complete console log)
oConsole= -Dweblogic.ext.dirs=C:\Oracle\MIDDLE~1\patch_wls1036\profiles\default\

Could not find the main class: ++Xmx512m. Program will exit.
Now to resolve this what i already tried are :
I change JAVA_HOME and PATH to jdk6 which came with web logic installer
Location is at :
JAVA_HOME : C:\Oracle\Middleware\jdk160_29
PATH : C:\Oracle\Middleware\jdk160_29\bin
The above dose not include any space between path
I ran the startWebLogic.cmd and got same error
After that I also added
CLASSPATH : C:\Oracle\Middleware\jdk160_29\lib\tool.jar;C:\Oracle\Middleware\wlserver_10.3\server\lib\weblogic.jar;C:\Oracle\Middleware\jdk160_29\bin
WL_HOME: C:\Oracle\Middleware\wlserver_10.3
I ran the startWebLogic.cmd and got same error
I also used earlier path which I used with eclipse when I was working on other java development.
JAVA_HOME : C:\Program Files\Java\jdk1.7.0_21
PATH : C:\Program Files\Java\jdk1.7.0_21\bin
I ran the startWebLogic.cmd and got same error
Then I also gave PATH: C:\Oracle\Middleware\wlserver_10.3\server\lib      (including the existing one using ; )
I ran the startWebLogic.cmd and got same error
Now may be there is a file called setSOADomainEnv.cmd in
< C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\ setSOADomainEnv.cmd>
That include some values for memory set :
set JAVA_OPTIONS=%JAVA_OPTIONS%
set DEFAULT_MEM_ARGS=-Xms512m –Xmx512m
set PORT_MEM_ARGS=-Xms512m –Xmx768m
if "%JAVA_VENDOR%" == "Oracle" goto OracleJVM
set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=128m -XX:MaxPermSize=768m
set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=256m -XX:MaxPermSize=768m
now as I change the red highlighted value to 512 value because I have less memory resource and I checked in installation documentation to change the above red highlighted value to 512 original is 1024 which is too high and it was crating problem and showing memory space problem so I change it to 512 and now I am not getting that memory space problem error but may be the above error is related with change value in setSOADomainEnv.cmd file or not
Following are my domain, weblogic and soa home directory path and all these path are exactly what it suppose to be according to Oracle Installation Documentation:
WebLogic :
C:\Oracle\Middleware\wlserver_10.3
C:\Oracle\Middleware\coherence_3.7
C:\Oracle\Middleware\oepe_11.1.1.8.0
SOA Oracle Home Directory :
C:\Oracle\Middleware\Oracle_SOA1
OSB Home Location :
C:\Oracle\Middleware\Oracle_OSB1
Domain name : soa_div_domain
Domain Location :       C:\Oracle\Middleware\user_projects\domains
Application Location : C:\Oracle\Middleware\user_projects\applications
Domain Location:        C:\Oracle\Middleware\user_projects\domains\soa_div_domain
form here i am trying to start weblogic : C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\startWebLogic.cmd
Please tell me any body want more details.
Thanks.

I think you are missing a character '-'
USER_MEM_ARGS="Xms512m -Xmx512m -XX:MaxPermSize=128m"Add this character like follows
"-Xms512m -Xmx512m -XX:MaxPermSize=128m"

Issue with setting an Action Listener for a Command Button

Hi all,
I'm trying to set an action listener for a CoreCommanButton in a backing bean. Here's my code:
     CoreCommandButton editBtn = new CoreCommandButton();
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",null);
          editBtn.setActionListener(mb);
//Action listener method
     public void doButtonAct(ActionEvent actionEvent)
I keep getting a javax.faces.el.MethodNotFoundException error. However when I remove the ActionEvent parameter in doButtonAct(), I get a wrong number of arguments error.
So i'm guessing there is something wrong with the parameters i accept in my action listener method. what can be causing this issue?
Cheers.

I figured this out.
Since doButtonAct() requires an ActionEvent object as a parameter, i needed to define the parameter type when I create the method binding.
Solution:
     Class argsString[] = new Class[] { ActionEvent.class };
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",argsString);

Message Driven Bean (MDB) for AQ Queue cannot start

I am working on the creating a message driven bean in Managed OC4J 10.1.3.0 to consume messages from AQ Queue. I am using a Oracle AS generic JMS connector and a resource adapter to create a message listener for the MDB.
I am able to make successful connections to the AQ and also consume messages, but if i try to start the MDB using the Oracle Application Server Web Admin console, the MDB fails to start, i have to restart the entire OC4J instance to restart the MDB.
The error on the Admin Console says "Failed to start MDB. Please see log for details." , but the problem is nothing is written to the log file.
I have tried setting the logging level in web admin console to FINER but still no new errors are written to the log file. I have checked the opmn logs, instance logs as well the home logs.
Please help, since this issue will further help us decide whether we need to go with the implementation or not.

As far as I know XMLType JMS messages are not supported when using OJMS. They might be for OC4J 10.1.3, but I thought it's an AQ limitation rather than an OC4J one.. To be sure you might just log a TAR on Metalink.

Info about Listener for oracle 10g and 11g installed on single systm

Hi,
I have installed oracle 10g n 11g on my system. I have question regarding oracle listener.
oracle 10g , Listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = kankala.kalyan)(PORT = 1521))
oracle 11g, Listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = kankala.kalyan)(PORT = 1522))
my question is why the listener's names are same even though thy are on different ports?
and for people worrying, why i have installed 10 n 11 is
Initally only oracle 11g was installed on my system. Later, I was learning forms for first time and i have to connect to database frm developer suite 10g. so i installed oracle 10g database.

The names are the same because that is the way you created them.
If you want to make a change use NETCA to drop and recreate one of them.
Just make sure you've defined ORACLE_HOME correctly before you do it.

Advice to implement a mouse listener for card game

Hi,
I am wondering about the best way to apply a mouselistener in my card game.
- i only want to listen for 'clicks'
- I have a JFrame with a JPanel inside. The JPanel has a null layout and many JLabels. The JLabels are the cards, i want to listen for mouse clicks on these 'cards'
I have seen it is not possible to apply a mouse listener to a JPanel or JLabel so is the most efficient way to apply the listener to the JFrame and then use getComponent () to determine which JLabel has been clicked ? or is there a better way ?
any thoughts appreciated . .

hey dubai, thanks for your quick help today, it is much appreciated !
i know the event should provide a reference to the source, i use the toString to overide the methods in the mouseEvent object and im printing this string to the console. It gives me the correct dimensions within my JPanel of where i clicked but the source is always given as the panel name. Have you any idea why it does not return the name of the JLabel ? I checked out the Action interface, thanks, it cud be very useful to seperate the code by using this.

Listen for a file?

Hi, i am trying to implement a java program that processes a xml file in a virtual directory. I need to, some how, run a java program that listens for a xml file that is uploaded from one server to a virtual directory on another server where the code is listening. I don't really know where to start with the listening code, and needed some help in the general direction of how to do it. Also i was thinking that when a file is found it is processed using a new thread so that the main thread can carry on listening. Would this be feasible?

Is this more or less what you had in mind?import java.io.*;

SWF panel listener for changed selection

In short, my question is as follows. Is it possible to create a listener which
detects when the current selection in the Flash authoring tool has changed,
and informs my SWF panel? This does not have to be a listener per se,
it can be some hand-crafted process which consumes some reasonable amount of processor time.
I describe my question more precisely below.
Suppose that I want to create an SWF extension panel for Flash (in Flash or Flex),
and I would like the panel to display a property of the object currently selected on scene
in the Flash IDE -- like the instance name of the object (if it exists).
I can use JSFL to detect the instance name of the selected object, and pass the string to the
SWF panel using call(), for instance. The problem is that I don't know how
to detect that the user has selected the object, or that the selection has changed.
Ideally, I would like to add an event listener that listens for such an action in the flash authoring tool.
However, using JSFL, this does not seem to be possible (I can only listen to events such as frame changed
or layer changed, but not selection changed).
I tried the following solutions:
1. Periodically check in JSFL whether the current selection has changed.
The problem is that in JSFL, there is no sleep function, or anything alike. The javascript
methods setInterval and setTimeout do not work in JSFL. Therefore, in order to periodically check for changes,
one must actively loop. This is extremely resource-consuming -- in fact, it hangs the flash IDE.
2. The periodic check can be triggered by the SWF panel itself. In actionscript, I can use setInterval to periodically
invoke the selection update function via JSFL. I have set the interval to 400 milliseconds, which gives a reasonably quick
reaction to changes. However, the functionality I want to implement is in fact more complicated than just retrieving the
instance name of the selected object. As a consequence, performing this operation every 400 milliseconds still consumes
too much processor time (the flash IDE consumes 30% of my processor time, even if the user doesn't do anything).
Therefore, I still would like to find a solution which does not use the processor when the user does not do anything in the Flash IDE.

I'm trying to do the same thing. Did you find a solution?
