Calling Session Beans in JSP ?

Hi Folks,
I am new to EJB3, I am doing simple applicatuions.
Can any one please tell me how to call session beans in jsp page.
for example my case is.. iam entering two diffrent data, lets say user name and password in jsp page and this should go in data base thru JPA (entity beans)
Iam able to enter data from JPA in data base but if the same i have to fetch from JSP page.. iam not getting..!
I would really appretiate for your help i need it urgent...!
thanks in advance.

Not. You can, technically, but you shouldn't. JSP should be for display purposes only, containing no Java code whatsoever.
for example my case is.. iam entering two diffrent data,Wrong. You cannot possibly have "2 data", the very concept is impossible.
You can have "2 data items" which is probably what you intended to say?
lets say user name and password in jsp page and this should go in data base thru JPA (entity beans)
Iam able to enter data from JPA in data base but if the same i have to fetch from JSP page.. iam not getting..!
Same way you insert them. Of course JPA entities are distinctly different from entity beans. The very concept of entity beans no longer exists in the context of JPA, it's solely used to mean EJB 2.1 or earlier entity beans.

It's not urgent.

How to call session bean's method in JSP

Hi All,
I am working on a JSF web application by using sun studio creator.
The first page have a button, the onClick javascript is as following, which bring up a alert box showing user login name.
In JSP file, how can I call session bean's setUserName(String name) function (which I would like to store this UserName). So the following pages can use this information.
If I can not do it this way, is there any other way to do it?
Thanks in advance.
var net = new ActiveXObject("wscript.network");
alert(net.UserName);
In managed-beans.xml
<managed-bean>
<managed-bean-name>BasicInfo</managed-bean-name>
<managed-bean-class>treepractice.BasicInfo</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>

You can find more information/details/examples at their own website.
On the other hand, do you realize that that ActiveX stuff is IE proprietary? And that it is a browser configuration whether to allow them or not? And that this configuration is in IE7 defaulted to an (annoying) warning box before execution which is just bad for the user experience?
With other words, forget that ActiveX garbage. Alternatives are Applets (not recommended) or Java Web Start (recommended).

Why not?
You can call Session Bean from a Message Driven Bean as long as your J2EE Server is able to handle the messages.

How call session bean from Client side

Hi
calling session bean from client side it gives Lookup erroe, it gives JNDI error
how we know session bean is working. in Admin tree bean statis is reb Flaf, and ID is "Down" how we activate it..
null

If you can make a connection using sess_sh, then you know that you have configured your database and listener properly. If it is not working, read the manuals that you can download from technet. They are pretty good, and if you follow the directions, you should see success.
Good Luck!

How to call java bean from jsp

hi
How to call a java bean from jsp page..
Is any other way to call javabean from jsp page apart from this sample code...
<jsp:useBean id="obj" class="com.devsphere.articles.calltag.TestBean"/>
thnx in advance

If you also use servlets, you can attach beans to the request or session and use them directly in your JSP's. So if you do:
request.setAttribute("name", yourBean);and then forward to a JSP, you can reference the bean like:
${requestScope.name}

Looking up a EJB 3.0 Session Bean in JSP Scriptlet

Hello There,
Somebody please enlighten me. I have a bean named
a.b.MyBeanextending local interface
a.b.MyLocalNow I want to use this bean in a JSP (Maybe just for fun, but the point is I am not using resource injection).
So the question is, What is the default JNDI name of the session bean with only a local interface, which I can use to look-it-up in jsp scriptlet code.
Cheers. Am trying for last hour, nothings turned up
Bye

It's the classname under the initial context or a.b.MyLocal in your case.
 <% MyLocal intf = null;
 try {
 InitialContext context = new InitialContext();
 intf = (MyLocal) context.lookup(MyLocal.class.getName());
 } catch (Exception ex) {
 System.err.println("Error looking up MyLocal: " + ex.getMessage());
 } %>

Calling session bean's business method through web dynpro component

Hi All,
Can anybody tell me how to call a session bean's methods through a web dynpro WITHOUT java-model or web service model ??
I have following scenario:-
1. Stateless Session bean having two business methods
2. Web Dynpro component
3.Now i want to call business methods without using any model. I have got following piece of code but I dont know how to go about it.
4.Where do i have to set JNDI name for session bean? which interface will be looked for?
5. Do I have to declare public part for EJB DC? If yes, how?
//This is inside web dynpro component
InitialContext context = new InitialContext();
o = context.lookup(JNDIName);
TestSessionbeanHome homeRef = (TestSessionbeanHome) PortableRemoteObject.narrow( o,
TestSessionbeanHome.class);
TestSessionbean beanRef = homeRef.create();
<returnValue> = beanRef.<ejb method name>
Please help to get a step-by-step approach to this case.
Thanks and regards,

Hi,
If I comment out the part that is using session bean's business method, DC is building fine.
And if I uncomment, then compiler is unabl eto resolve business method(s).
And i would like to mention that my EJB + J2EE App DC is building properly, but it havent yet deployed properly as I am waiting for data-source-alias name prefix to be configured by ERP team. So will this be a reason why Web Dynpro DC is not able to resolve business methods ??
Because Web Dynpro DC is able to resolved all interfaces of Session bean and entity bean. But when it comes to business method, its not able to resolve.
Any more ideas why it is not happening?
Pls help.
Now i went through some forum posts regarding this and found that we also need to add EJB DC to Java Build Path for WebDynproDC>Properties>Java Build Path.
I did this and now it is able to resolve business methods and DTOs as well. So to summarize I did following:-
1. Added EJB DC (complete DC) as a Used DC to Web Dynpro DC with Buid-n-Deploy-n-Run time dependency
2. Added Sharing reference of J2EE application DC to Web Dynpro DC -->Properties
This reference I constructed as follows:-
<vendorname>/<name of j2ee application as appearing under display name tag in application.xml (replacing '/' with '~')>
So my Sharing Reference becomes:- <vendorname>/reqpstapscreqpstapja_reqid
3. Added EJB DC to Java Build Path in Web Dynpro DC's properties
4. Then I added following piece of code to get object of SessionBean class
InitialContext context = new InitialContext();
Object o = context.lookup("java:comp/env/ejb/SessionRequestIDBean");
SessionRequestIDHome homeRef = (SessionRequestIDHome) PortableRemoteObject.narrow(o, SessionRequestIDHome.class);
SessionRequestID beanRef = homeRef.create();
beanRef.<business method>
But After doing this I am facing another problem :-
The build fails saying it is not able find the package for DTOs. But when I see the Component Controller's code it is not showing any red or yellow marks.
Can anybody pls help me out here?
Thanks and regards,
Amey Mogare

Using session bean in JSP

Dear All
I write a BorrowList session bean and tested OK in console mode. I can't use it in the JSP, Dose any body tell me How can I create this bean in the JSP and when should I place the bean classes(Home, Bean and Remote).
I'm now using the BEA Weblogic 7.0
I'm appreicate if anybody can help me.
Best Regards
YU

U may be used the code similar to following :
Context context = new InitialContext.();
Object obj = (Object)context.lookup("Your JNDI name");
YourHome home = (YourHome)obj.portableRemoteObject.narrow(obj,
YourHome.class);
YourRemote remote = home.create();
System.out.println("your Business methods : "+remote.businessMethod1());
Put this code or whatever code used in ur console client in JSP and invoke the businessMethods using remote object.
I worked with BEAWeblogic 5.1, I think similar case may be there with BEA Weblogic7 also.
First, make a jar file with ome.Remote and Bean by using the deploymenttool, then compile with ejb compiler, the new Jar is the complete deployable file. Take this file and register in weblogic.properties file that is specify the path of the Jar file in the weblogic.properties file. and put the JSP in public-html directory and start the server. if the bean is deployed successfully, open JSP file in a browser then it will work.... if the bean is not deployed you won't get any result.
I can say, just placing the initialContext part of code on the JSP and running the JSP. I think, this may helps u...

Problem when calling session bean from main.

Hi everyone
I get the following error when calling a session bean from main(String args[]).
Sep 3, 2008 9:11:13 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>
WARNING: ACC003: Application threw an exception.
java.lang.NullPointerException
at databasetest.Main.main(Main.java:26)
Here is my code beneath.
I'm using netbeans and glassfish application server.
Everything is in the same project, called DatabaseTest, I also have deployed the application before running the client.
I'm running the client as follows, right click on the DatabaseTest-app-client and select run.
The client:
package databasetest;
import com.test.UsersFacadeRemote;
import javax.ejb.EJB;
import com.test.Users;
public class Main {
 @EJB
 private static UsersFacadeRemote usersFacade;
 public static void main(String[] args) {
 Users users = new Users(12, 34);
 usersFacade.create(users);
}The remote facade I'm calling:
package com.test;
import java.util.List;
import javax.ejb.Remote;
@Remote
public interface UsersFacadeRemote {
 void create(Users users);
 void edit(Users users);
 void remove(Users users);
 Users find(Object id);
 List<Users> findAll();
}The stateless bean:
package com.test;

import javax.persistence.PersistenceContext;
@Stateless
public class UsersFacade implements UsersFacadeRemote {

 public Users find(Object id) {
 return em.find(com.test.Users.class, id);
 public List<Users> findAll() {
 return em.createQuery("select object(o) from Users as o").getResultList();
}

looks like you're banging your head against the same brick wall as [I have done|http://forums.sun.com/thread.jspa?forumID=13&threadID=5317110] and [others have in the past|http://forums.sun.com/thread.jspa?forumID=136&threadID=5259913] if that's any consolation.
Funny thing is, mine did actually work in the debugger but not when running!
Strange thing that.
I did initially interest someone from the developers but they couldn't really help, ended up saying : try instantiating your beans the EJB 2.1 way and see where that gets you. Yes that works but they promised us "hey no more dopey xml deployment descriptors just some cool annotations" didn't they?
I've got the feeling were' missing something really obvious!

Session management in session bean calling session bean

Hi,
 I've got another question on transaction.
 I have following stateless session beans :
 session1 with trans-attribute Required.
 session2 with trans-attribute Required.
 session1 calls session2 and session3.
 session2 inserts/updates records in the database.
 What am doing is first I call a createSchedule method in session2, which
 creates a new record in the database.
 And then I call an update method on the session2 bean, that will fetch and
 update the newly created record.
 This second update fails, due to some database constraints.
 What I was hoping, that the record should not be created in the database,
 but it did.
 The first method call in session2 succeeded and the second failed !!
 Doesnt both the DML be part of one transaction ?
 Thanks
 Amit


Solved this one too :
 What was happening was, Before I called the create method of the session
 bean, I was calling a find method, and I was capturing the exception, and in
 case theres an exception, assuming that there is no record in the database,
 I create a new record. This find method is in the same session bean,
 session2 along with the create and update methods. Inititally when there was
 no record, the session bean was raising EJBException, due to which the main
 session bean, session1, rollbacks the transaction, it started, but as I was
 catching this exception, so the execution continued, .... next statement
 being create, and as the transaction attribute of it was Required, and as
 the session1 bean's transaction has already been rolled back, there was no
 transaction, so the create method started its own transaction, and created
 the record, and then the update method too did the same, but it gave an
 error, so only update method's transaction got rolled back.
 So I changed the find method to throw FinderException, instead of
 EJBException, so the transaction of sessio1 bean is not lost.
 Its working now.
 But the other problem I posted, where I dont want to throw any exception to
 the client calling the session1 bean, I still havent figured it out, how to
 stop it, although am catching all the exceptions, still the client got
 exception.

Help requested: call session bean over network

Hi
I want to know how to call a session bean on the application server from a normal java program on another machine on the network.
I plan to create a stateful bean in the application server; Make it return its context ( i assume i need to serialise it before sending the context over) to my program. Alternatively I can try to send the EJB handle back.
once my program gets the context or the handle back, I will create a new stateless bean in the application server and pass this context or handle so that it can locate the stateful bean to get the data in it
please advise
thanx
Gaurav
ps> I know the issue involves RMI and security issues but I dont know in depth exactly how to go about it .

Just code a simple client and hit the EJB. (Assuming the m/c is in the LAN).
If there is a firewall between the m/cs, i am sorry my dear friend you will have to go extra miles to do so.

First reaction: yuck.
This is not something you should be using a bean for.
Beans are meant for storing data, not for generating HTML from.
I don't really like queries on a JSP page either, but thats a different story again.
I would recommend you use JSTL for this.
1 - it provides a c:forEach tag for looping
2 - it provides sql tags for doing queries in a database
IF you are going to do database queries from a JSP page, I absolutely recommend you use the JSTL tags.
(end rant)
Your problem is probably caused by the fact that in your bean you have the following
try{
// code here
catch (Exception e){
// completely ignore exception and carry on as if nothing bad happened.
// what you should be doing is something like:
System.out.println("Error occurred " + e.getMessage());
e.printStackTrace();
return e.getMessage();
