EJB beans constantly loaded?
I have recently ported my EJB 2.1 project to EJB 3.0.
However, it seems that the new EJB 3.0 beans are constantly created and loaded from the database. E.g. when I look an entity bean I have used before during the session up, a new bean instance is created and loaded from the database. One would expect that the Entity Manager would find the old instance in the memory and return it. This is what ORM is all about, right?
In EJB 2.1 this behaviour can be changed by setting the commit-option to A. But, now this doesn't seem to help :(
Any help would be more than appreciated!
Best regards,
Igor Vukmirovic
You can write Java code in your JSP which looks up an EJB and invokes methods on it.
However it's better to use ordinary Java beans to do the EJB lookup and invocation, and access the Java beans from a JSP.

ThomasIt means the pool doesn't have a connection available for this thread to use, after waiting
some time for any other thread to return one. Either your pool is not big enough, or your
bean code may sometimes be forgetting to close any connection it gets. Note that in
a stateful session bean, you may fall into the trap of retaining a JDBC connection open
for the duration of the session. If you do this, your pool must have as many connections
as the maximum number of simultaenous sessions you want to support. Usually the aim is
to obtain a pool connection, use it, and return it to the pool, all within any single response
to the client. Then you only need as many pool connections as there are execute threads
in the server. Having a DBMS transaction that spans user input is an invitation to deadlocks,
bottlenecks in performance etc.

Entity beans not loaded due to problem loading WebLogic_RDBMS.jar dynamically
Hi,
I'm new to WebLogic so bear with me! When I start WebLogic (using
Microsofts SDK for Java 4.0), all me session beans load up fine, but none of
my entity beans load. The error I get for each is:
[EJB]: Server cannot load: d:\weblogic\lib\persistence\WebLogic_RDBMS.jar
dynamically. Attempting to load from classpath
... and then it goes on to say that it could not deploy the entity bean jar
file giving a list of possible reasons. I'm guessing that the problem stems
from the fact that the persistence jar file could not be loaded (correct me
if I'm wrong!).
Has anyone come across this before? I have included the WebLogic_RDBMS.jar
file in my classpath when I start WebLogic to see if this would help but to
no avail.
Any help would be really appreciated.
Thanks,
CiaranPlease see my response in the ejb newsgroup.

Where to put jar file containing non ejb beans
Hi everyone,
i would appreciate a lot if someone could tell me where i could place my jar file
which contains non ejb beans
thanks
Hi,
I´n not sure what you mean. But if you mean a JAR containing utility classes for
your EJBs or Servlets you should put it for EJBs into the META-INF/lib directory
of your EJB JAR or for Servlets/Webapps into the WEB-INF/lib directory.
So the JAR file will be automatically loaded from the right classloader and can
be used.

Hi,
I have a problem binding EJB bean (Stateful bean). Bean have two business methods:
SendPacketToTRSM and GetData
When I invoke SendPacketToTRSM method from process, application server create first instance of bean and invoke method SendPacketToTRSM
Next I invoke GetData method in process, application server create second instance of bean and invoke method GetData.
Every time, when I invoke method, application server create new instance of bean and don't remove it.
Application server after passivation remove instance of bean from container.

Could anyone explain, is it possible to binding stateful bean to process?
Thanks
NorbertDid some additional investigations and concluded"
The (embedded) OTC uses default the empty to obtain the reference to a Session Bean (EJB). In my case I was using the Remote Interface and my Context was empty { }:
Hashtable ht = ic.getEnvironment();
System.out.println(ht.toString());
When I supply the missing information, obtained via the Test Client that functions correctly, a new Bean instance was created for each Client. My getInitialContext() method looks like the example below.
public InitialContext getInitialContext() throws NamingException {
Properties p =new Properties();
p.setProperty( "java.naming.factory.initial", "com.evermind.server.rmi.RMIInitialContextFactory");
p.setProperty( "java.naming.provider.url", "ormi://localhost:23892/current-workspace-app" );
I tried the ApplicationInitialContextFactory and again the same Bean instance was shared among all Clients. I did not try ApplicationClientInitialContextFactory, but I expect that the Remote interface will be used!
Is it a Bug that ApplicationInitialContextFactory does not create a new instance for my Stateful Session Bean? I can use the Remote interface, but that would decrease the performance and it is less elegant...

Problem in accessing a EJB bean through a servlet
Dear all,
I'm a trying to call a stateless session bean which has its home and component interfaces, which prints the name it receives from the servlet client.
I'm trying to access a remote server EJB beans, which has been registered with JNDI & when deploying the EJB beans onto the Jboss server which operates in localhost: 8081 it has shown
20:19:16,890 INFO [EjbModule] Deploying greetBean
20:19:17,109 INFO [ProxyFactory] Bound EJB Home 'greetBean' to jndi 'greetJndi'
20:19:17,125 INFO [EJBDeployer] Deployed: file:/C:/jboss-4.0.5.GA/server/default/deploy/greet.jarThis is my servlet which is there in tomcat container which runs in localhost:8082 to access the bean:

import javax.ejb.*;
import javax.rmi.*;
import java.rmi.*;
import javax.naming.*;
import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class greetServlet extends HttpServlet
public void doPost
(HttpServletRequest req, HttpServletResponse res)
throws ServletException,IOException
res.setContentType("text/html");
PrintWriter out=res.getWriter();
try
out.println("Inside servlet");
Properties props=new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
*props.put(Context.PROVIDER_URL, "localhost:8081");*
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
System.out.println("Properties ok");
Context ctx=new InitialContext(props);
System.out.println("context ok");

ctx.lookup("greetJndi");
System.out.println("home ok");

System.out.println("remote ok");
String a = req.getParameter("text1");
String s = remote.greetme(a);
System.out.println(s);
out.println(s);
catch(Exception e)
{System.out.println(""+e);}
}When i try to access the bean it's throwing a communication exception. The exact stack trace is:
javax.naming.CommunicationException: Could not obtain connection to any of these
urls: localhost:8081 and discovery failed with error: javax.naming.Communicatio

ception]]Could anyone say why this is occuring and how this can be fixed.
Thanx in advance.when i change the properties url attribute to jnp://localhost:1099 like
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");It's throwing unmarshall exception:

I have a session bean deployed on Weblogic 8.1, when I try to call a method on bean from a simple class (out side of server context) it is just calling the method on the remote object but not Bean object.
I made a jar file and deployed it through weblogic console, It worked fine when I test with Test this EJB link on the Testing Tab on console.
client class was not part of jar.
weblogic-ejb-jar.xml
<weblogic-enterprise-bean>
<ejb-name>Create</ejb-bean>
<jndi-name>java/CreateHome</jndi-name>
</weblogic-enterprise-bean>ejb-jar.xml
<ejb-jar>
<enterprise-beans>
<session>
<ejb-name>Create</ejb-name>
<home>CreateHome</home>
<ejb-class>CreateBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>container</transaction-type>
</session>
</ejb-jar>client code
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory")"
InitialContext ctx = new InitialContext(ht);
Object obj = ctx.lookup("java/CreateHome");
CreateHome home =
(CreateHome)PortableRemoteObject.narrow(obj,CreateHome.class);
Create remote = home.create();
remote.callSomemethod();any help will be appreciated, thank youSorry guys please ignore my post.
It was working fine, I was not looking at weblogic Server logs for my ejb printouts , instead I was looking at logs for the Client code in Net beans.
sounds stupid right ? -
Is there a possibility to implement a Portal Services by EJB Bean?
Let suppose we have a Portal Service class ITestPortalService and EJB called TestEJB
Can we do this in this way or any other way?
public class TestBean implements javax.ejb.SessionBean, TestPortalServiceQuestion: Is there a possibility to implement a Portal Services by EJB Bean?
I don't think you can do this directly as the portal service is maintained and called from the irj (portal) application, while the EJB beans are called directly from the web application server (as far as I know).
The only think you could do is to have the Portal Service be a bridge, which basically only calls the EJB and returns the results. -

How drive ejb beans from such as COMPANY with..
I am very new to EJBs but would like to give a try and dooooooooooooo it of course. Now, I understnad how to write jave(ejb interfaces and classes) but makes me small is how define ejb beans from my bosses speach. He says we need to ....... so for example COMPANY(company name, contact, references + more) could be our business objects. HAH!
So pmy roblem is what should be an ejb bean and what should be ejb bean fields.
Thanks a lot in advance.
gapterIts really not that difficult really. First - if you decide that your business object is going to be a Bean - Determine if it should be an EJB or just a regular Java Object bean in which case you'll probaly just use a Java Bean. The two are very similar with the exception that JB's are not Distributed but can do most of the grunge work that an EJB is suppose to do.
Next, determine what business methods or transactions are most likely to be done to your Business Object. This should determines the interface. So far that's all routine.
If you are decide that an EJB is what your problem demands (after much research into your problem) - then ask if your business object will be persistent (exist for a long time and will need storage (say on a persistent storage media like in a database) Or whether it will just require session scope (or just to be present the duration of a transaction/session - like say a shopping cart). The former requires a Entity Bean, the latter a Session Bean.
You then create your implementation code in a NameOfClassEJB class. A Container Management class NameOfClassHOME, and of course your Business Method Interface called NameOfClass.
The BMI (business method Interface class) is trivial. Your EJB class however will contain all the implementation required to get work done depending on the choice of Implementation - that is, whether you wish to handle all transactions (Bean Managed) or if you would rather delegate to the Container to handle Storage Issues (Container Managed). With Container Management - You get a lot for free - like concurrency control, database connectivity is trivial, distributed transaction management is trivial, field updates in your database is totally out of your hands. etc ...
For a beginner - its better if you take time to study the ejb lifecycle, the J2EE Business Architecture, then the solution that they proposed for application development. This is not trivial and has a steep learning curve.
Have fun.
Next determine if you want to handle all of the transactions between the properties (or fields) in the bean or you'd like the Application Server's Container to do this for you. (Most EJB's at least the simple ones are better off being handled by the Container).

Can EJB Beans explicitly make RMI calls?
Hi,
I'm new to EJBs and would like to know if an EJB bean (especially a session bean)
can explicitly make RMI calls to remote objects that are not EJBs?
Thanks in advance to your advice.
cc.The best approach here in my mind would be to bind the RMI object to a JNDI name then have your bean lookup the RMI object with JNDI and then make the calls.

Voicemail constantly loads, and I can not stop it. Help!
I have an LG phone, and the voicemail constantly loads. I have tried to stop the program with no results. What next??
Which LG phone? And is this the Visual Voicemail app, or the standard Verizon voicemail? I'm not sure what you mean by loading constantly? Do you have voicemails waiting? Can you call in to your voicemail?

Thanks for taking the time to read.
A few weeks ago my macbook pro's desktop stopped responding. The cursor is in the loading stage whenever I hover it over the desktop, but I can use my browser and anything else in my dock just fine. (No loading icon in the browser or other programs) This is very inconvenient when I'd like to use programs not on my dock, etc. On top of that I believe this problem is also affecting my ability to download new programs. When the program I'm trying to download reached the "finishing" stage it constantly loads.
I've tried restarting.
I tried going into safe mode and then going back out of safe mode.
Any help would be very appreciated. Thank you very much.Double-click on the hard drive icon in the Finder. It should tell you how much room is available.

Restrict number of simultaneous connection from client to EJB bean
I have EJB bean and JavaSE client. I want to restrict number of simultaneous connection from client to EJB bean. For example to maximum allowed 3. How I can do it?
:) but answer is too general.
I want to know how to design such "simple reference counting". As I understand it is not recommended to use static variables in EJB. so how to implement such counting in a right way?
