How to lookup EJB3 beans using JNDI names without defining ejb-ref in DD?

Hi Kenneth,
I am just continuing the topic:
How Lookup SLSB from other SLSB? <HELP>
http://forum.java.sun.com/thread.jspa?threadID=5117484&tstart=0
(my original forums account failed, so I am using new one)
if I am not seeking portability I should be able to lookup a bean directly through JNDI without using the ejb-ref. (I just want to see how it can be done)
http://forum.java.sun.com/thread.jspa?forumID=13&threadID=751907
http://www.theserverside.com/discussions/thread.tss?thread_id=16402
I am using SJSAS PE 9.0 I am failing to lookup my beans from other beans directly without ejb-ref.
Is there some sample code to look at?
Thanks!

Global JNDI names are vendor-specific and not known until deployment time. That is one
of the main reasons the Java EE component environment model defines a level of
indirection for accessing component dependencies. It is best to use either an ejb-ref
or @EJB annotation when accessing EJBs from a Java EE component.
If you choose not to, you just have to make sure the global JNDI name you use matches
the one assigned to the target EJB. We have a lot of information on how this works
in our EJB FAQ.
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html
If you're still encountering an error, please provide more specifics about your application,
the code you're using for the lookup, and the error message you're receiving. Just
saying "my looking fails" doesn't help us diagnose the problem :-)

How to get the JNDI name of an EJB from within itself

Hello,
I'm trying to find a way to get the JNDI name of a session bean from
within itself.
In the application I'm working on we need to support multiple
customers. In order to do that, each EJB has a normal home and remote
interface, a base class bean implementation and different children
bean implemetations for each customer (when the logic for the
customers is different). JNDI is used to get the proper implementation
based on the customer.
I've got an EJB that provides some services that are the same for all
customers, except for the fact that it contains one variable that
should have a different value depending on the customer. I don't want
to creat subclasses just for that. What I want is to be able to get
the JNDI name and set the variable based on the it.
Is there a way to get the JNDI name for the EJB from within itself?
TIA

Setting up LDAP Server to lookup Connection Factories using JNDI

Can someone let me know how to setup LDAP server within 10G to lookup connection factories using JNDI?
I read through the Advanced Queuing User Guide and Reference document where this is mentioned and it says use the Database Configuration Assistant to do this but I could not find how.
When I install 10G is LDAP server automatically setup? How do I get to it?
Thanks

That is correct. I was indeed able to use the app server (10g) to give the LDAP user permission to access the objects, then used sql commands to register the objects inside the LDAP.
However, I am finding NOTHING about actually creating a unique connection factory that can be registered in the LDAP. I find reference to registering Queues/Topics/Factories inside the LDAP, but nothing about actually creating the factories.
In fact, here
http://download.oracle.com/docs/cd/B28359_01/server.111/b28420/aq_envir.htm#sthref409
it's listed that you cannot use sql to create a connectionfactory... not to mention the create java commands for factories look strikingly similar to the queue/topic GET commands, and not the create commands. You can add an alias for that factory using sql, but can't actually create the factory using sql... ???

How do you create beans using NetBeans 5.5?

I am referring to http://java.sun.com/docs/books/tutorial/javabeans/nb/index.html and I'm sorry but I can't follow any of this!
I have NetBeans IDE 5.5 and I am trying to learn how to write beans using NetBeans, and the lessons involve things I can't find or understand, for example:
re: http://java.sun.com/docs/books/tutorial/javabeans/writingbean/index.html
<blockquote>
Load the JAR file. Use the NetBeans IDE GUI Builder to load the jar file as follows:
1. Start NetBeans.
2. From the File menu select "New Project" to create a new application for your bean. You can use "Open Project" to add your bean to an existing application.
3. Create a new application using the New Project Wizard.
4. Select a newly created project in the List of Projects, expand the Source Packages node, and select the Default Package element.
5. Click the right mouse button and select New|JFrameForm from the pop-up menu.
6. Select the newly created Form node in the Project Tree. A blank form opens in the GUI Builder view of an Editor tab.
7. Open the Palette Manager for Swing/AWT components by selecting Palette Manager in the Tools menu.
8. In the Palette Manager window select the beans components in the Palette tree and press the "Add from JAR" button.
9. Specify a location for your SimpleBean JAR file and follow the Add from JAR Wizard instructions.
10. Select the Palette and Properties options from the Windows menu.
11. Expand the beans group in the Palette window. The SimpleBean object appears. Drag the SimpleBean object to the GUI Builder panel.
</blockquote>
Sorry, you lost me literally after "Start NetBeans", the rest is Hungarian. I can't find "New Project Wizard"; I can't find "List of Projects", I can't find anything they are talking about nor do I know if any of this is relevant toward my learning how to write beans.
Re: http://java.sun.com/docs/books/tutorial/javabeans/properties/properties.html
"Inspecting Properties" seems impossible to do because the Inspector Window only shows a closed folder and nothing else ever. I can't figure out this part of the tutorial either.
Can someone please explain this 3rd-grade-level to me: How to create a bean using NetBeans?
Thanx
Phil

Phil,
Before you embark on another very frustrating advanture using NetBeans, please go t hrough the NetBeans tutorial. The "New Project Wizard" is just select from the menu options -- "New Project". The "Hungarian" as you put it will not get better until you spend some time learning NetBeans. Learning something new, like beans, is frustrating enough, but to try to do it and use a tool that is not familiar may be beyond many individuals frustration level.

How can I configure ang use JNDI datasource on Tomcat 4.0.x ?

How can I configure ang use JNDI datasource on Tomcat 4.0.x ?
Please help me , Thanks !

Hello ,
You need to go through the JNDI tutorial which you can access at the sun's site. It will explain all the things you need.
By the way all you want to use JNDI datasource is JNDI class library and some naming or directory service provider, which also you can download from sun.
Good Luck.

Dynamic jndi-name in weblogic-ejb-jar.xml

Is there a way to create dynamic (i.e. runtime) jndi-names for EJBs instead of
(or in addition to) "hard coding" them in the weblogic-ejb-jar.xml file? What
I'm trying to do is have one WebLogic instance (JVM) host multiple environments
(our Beta and Training environments) and I simply want to deploy the same .ear
file twice but have each environment (application - .ear) reference a different
database schema (jdbc connection pool). I have everything working just fine for
this scenario except when I define jndi-names for our ejbs. The problem is that
I am really deploying the same ejbs (jndi-names and actually code base) in each
applicatoin instance and I get an exception when the WebLogic is trying to deploy
the second application (.ear) because the jndi-names in it have already been deployed
by the first application instance. I recieve a jndi error stating that the name
is already deployed.
Or is there a better path to go down for what I am trying to do to have one WebLogic
instance support our beta and training environments? Usually (but not always)
our code base is the for same for both of these environments, I simply need to
have each environment use a different database schema.
Thanks

A little birdie tells me that BEA does this very thing. Looking at the
descriptors for WebLogic Portal I see:
<weblogic-enterprise-bean>
<ejb-name>LoaderEJB</ejb-name>
<enable-call-by-reference>True</enable-call-by-reference>
<jndi-name>${APPNAME}.BEA_content.LoaderHome</jndi-name>
</weblogic-enterprise-bean>
Yes, the ${APPNAME} token really is expanded into the J2EE application
name at deployment time!
Sincerely,
Daniel Selman

How do I create and use a ringtone without syncing and without jailbreaking?

How do I create and use a ringtone without syncing and without jailbreaking?

You create ringtones on your computer and sync them to your iphone.
You can buy ringtones from the ringtones section (at the bottom of the screen when you open itunes) of the itunes app on your iphone.
There may be apps that will do this - not sure.

I want to use variation funtion without define the characteristic...

Dear.
I want to use variation funtion without define the characteristic into general data selection in making report painter.
Finally hopeful thing is, The extract data which contain that characteristic group should be used in the whole sub-hierarchy
automatically such as I did that in general data selection.
For example, supposing the profit center group A is composed like below,
A
└─ B
└─ C
.....└─ D
When I make report painter, if the profit center positioned in lead column not general data,
I can't use variation funtion in profit center. So, I must save extract data each profit center group manually. (A,B,C,D..)
It is so uncomfortalble.(Guess the profit center group composed over hundreds.)
You know, the profit center located in general data, I just need to extract data only once in A. Then B,C,D also saved automatically.
Why can't do this in former case ? If possible, please let me know.

Could not access Local Session Bean using JNDI lookup

Hi EJB Guru,
I am quite new to EJB 3.0 but have had a good deal of success including using JNDI to lookup Remote Stateless Session Bean in EJB 3.0. However, looking up local Stateless Session Bean prove more challenging with I had anticipated.

        CalculatorLocal calculator = (CalculatorLocal) ctx.lookup("CalculatorBean/local");
        System.out.println("1 + 1 = " + calculator.add(1, 1));
        System.out.println("1 - 1 = " + calculator.subtract(1, 1));    }

        System.out.println("1 + 1 = " + calculator.add(1, 1));

Hi Henry,
Any direct global JNDI lookup is not portable. It works in some cases but not in others, which
is why we recommend using the portable Java EE approach of declaring an ejb dependency
and looking up that dependency via the bean's component environment (java:comp/env).
This is true whether you're dealing with Remote or Local ejb dependencies.
Local ejbs are not supported in the Application Client tier at all. In the server tier, there is no
guarantee that a Local EJB even is assigned a global JNDI name since there's no requirement
that it be available outside of the application in which the ejb is defined.
You can find more information on these ejb access topics in our EJB FAQ :
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html

Problem deploying cmp bean invoking another cmp bean using jndi lookup

I have a cmp BeanA that invokes another cmp BeanB, so I am using a jndi lookup in BeanA to download the localhome object to BeanB using the following:
Context ctx = new InitialContext();
home = (LocalAddressHome) ctx.lookup("java:comp/env/ejb/BeanBHomeRef");
then I specify the ejb/BeanBHomeRef, entity bean, local, BeanB's local home and component interface in EJB ref. when I am packaging BeanA
I also package BeanB in a separate jar file.
When I attempt to deploy the application it throws strange exception that says the folowing:
java.lang.IllegalArgumentException: BeanBEJB says it links to an ejb called BeanBEJB of local home class LocalBeanBHome but no bean with this local home c
lassname and type can be found in this ejb-jar.
yet when I un-jar the package, these class files exitsts.
When I go ahead and delete the reference to BeanB from the BeanA package file, I am able to deploy the application but then correctly fails on jndi lookup.
I have been able to open the cmpcustomer.ear sample application that comes with RI and execute it without any problem. But when I to package the same beans for example CustomerBean and it won't even allow me to create the customer.jar file. I get a screen full of errors.......
I am using Sun RI 1.3.01, is there a known bug that I am not aware of? Is there a fix around it?
Is there any another way to get the home ref. to BeanB so I can invoke create() method?
Any advice or suggestions?
thanksl

How to lookup a bean from a standalone app.

I've got the following question..
I've created a stateless sessionbean and deployed it in the J2EE Server 1.3.1. (That one you get from Sun when you download the J2EE SDK) I've created a client for my bean, and when i execute it with the 'runclient -client my.ear -name myclientclass' command, it works just fine.
But, i now want to run it as a standalone application, without the 'runclient' command. I am able to create an initialcontext (without any properties), but my bean can not be found in 'java:comp/env/ejb/bean' (the same name i use with the 'runclient' command, so the bean should be there). My guess is that i should add some initial context properties, but which ones? All the examples i can find are with ldap context factories. Can anyone give me any advice on how to connect to the J2EE server and lookup my bean?
Thanks in advance.
Nick

Hi,
You could write something as below
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp:localhost:1099");
env.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
try {
Context ctx = new InitialContext(env);
Session_LocalHome session_lh = (Session_LocalHome) ctx.lookup("Session_Home");
Session_ session_ = session_lh.create();
OR
Use a jndi.properties file which would have the same entries as above, please search over internet and find out what to include in it.
One more thing to note is, in above example i said
env.put(Context.PROVIDER_URL, "jnp:localhost:1099");
meaning the lookup is on port 1099, this is not same for all the servers. Check your server documentation and find out " What is the port number on which your server listens ? "

How to lookup a Bean?

i have successfully deployed an EJB by using J2EE deploytool.
my source code to lookup the Bean as following:
Context ctx = new InitialContext(System.getProperties());
java.lang.Object objref = ctx.lookup("skey");
home = (SessionKeyHome)PortableRemoteObject.narrow(objref, com.ibm.sessionkey.SessionKeyHome.class);
i have read serval books and articles,there are different codes for lookuping a bean.Why?and when should we use this or that?
But i get the error msg:
Warning: unable to read transaction.interoperability config property

Hi,
There r two ways to lookup. One is that u specify the provider while running the client. E.g:
java -D java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
-Djava.naming.provider.url=t3://localhost:7001
or alternatively u can specify these two properties in the Properties object of your client. e.g:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
props.put(Context.PROVIDER_URL,"t3://localhost:7001");
Context ctx = null;
Object obj = null;
try
ctx = new InitialContext(props);
obj = ctx.lookup("HelloJNDI");
Which method to use is matter of convenience.
Values of provider url & initialContext will change depending on the app server u r using.
I hope this will help u.

[AS2] how to access a TextInput using its name?

I want to change the text of a TextInput using its name for example.
("name1").text = "123"
or is it possible to create an array of components?:
txt[0].text = "123"
how to do it? thanks in advance

I'm not certain what your intention is, but if the instance name of the textfield is name1, then you can assign its text using:
name1.text = "123";
If you have an array of the instances, the same applies, so long as the array is assigned the instances and not string versions of their names.
var txt:Array = new Array(name1);
txt[0].text = "123";
If you have an array with strings of the instances names, then you need to use bracket notation to have the strings interpretted as instances...
var txt:Array = new Array("name1");
this[txt[0]].text = "123";

How to access an element using its name or id if it is not a class variable?

I am trying to retrieve the element I added to my UI in a different function. I am using actionscript 3. I know I can put the variable into a class variable, so it can be access anywhere in the class, but I have too many elements. Is there anyway I could access them without putting them into class variable?
Thanks.
public class Test extends SkinnableContainer{
// private var image:Image; <-- I try not to do this, too messy
private function func1() {
    var image:Image = new Image();
    addElement(image);
private function func2() {
    var image:Image = /* how to get the element from my UI without putting into class variable */

Here is what works for me:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx"
               creationComplete="init()"
               minWidth="955" minHeight="600">
    <fx:Declarations>
        
    </fx:Declarations>
    <fx:Script>
        <![CDATA[
            import spark.components.Image;
            private var image:Image;
            private function init():void
                image = new Image();
                addElement(image);
                trace(this["image"]);
        ]]>
    </fx:Script>
</s:Application>
