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).

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.
I would really appretiate for your help i need it urgent...!
It's not urgent.

Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.

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,

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!

what else i can do for?
may i know the solution with detailed
and please attach the solution of code to me if you know...
thanks...

Hi,
I am not clear with ur query..
What I understood from ur query is that, u are trying to put the session ejb in the HttpSession Object for some use ahead in future?
If this is the case, then I think are approach is not correct.
StatefulSession beans are meant for this purpose, i.e they will be maintaining the client session. So use the same using the JndiLookup of the HomeInterface and the getting the Home reference and calling the businessmethods

How to call a custom controller method from view

Hi,
I ve created a simple web service and consumed it in a model. Mapped the input & output parameters to custom controller context which in turn mapped to component controller's context which in turn to view's contexts.
How to call a custom controller method from view?
Please explain the syntax.
Regards,
Manoj.

Hi Patralekha,
Give some idea for the below scenario:
I ve created a simple web service and consumed it in a model. What I did was
1) for the input parameters, mapped the node from view->custom controller->model
2)for the output parameter, mapping from model->custom controller->view.
It works fine.
But I don't want to access model nodes directly, rather I want to set the input param in somewhere else (like custom controller) before calling the appropriate method, same for the response also.
Share me your thoughts.
Regards,
Manoj.

How to call a standard BOR method in a program.

Hi All,
How to call a standard BOR method in a program. For example I have to call BOR method ISUSMORDER.Release in my program but don't know how to call.
Also, plz tell me how to capture the Exceptions in case of BOR method.
Plz help me out in this.
Thanks,
Mithilesh

Would be easier (however not always possible), to determine the functionality of this method and call that in your program. I mean, normally this method calls a BAPI, or function module (or a transaction). Have a look at the coding inside of the method, and try and use this.

How to call the screen in methods could u please explain

hi,
how to call the screen in methods could u please explain clearly with example

HI ,
CALL SCREEN - Call a screen
Basic form
CALL SCREEN scr.
Addition:
... STARTING AT x1 y1 ... ENDING AT x2 y2
Effect
Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
Note
Please consult Data Area and Modularization Unit Organization documentation as well.
Addition
... STARTING AT x1 y1 ENDING AT x2 y2
Effect
The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
Note
If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
Exceptions
Non-Catchable Exceptions
Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
Runtime Error: DYNP_TOO_MANY_CALL_SCREENS

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 to call a bean method in the faces-config file?

Hi,
I would like in my menu to call the method of a bean (it initialize some properties before opening the page) instead of opening directly the page, by I can't find how to do that.
I tried :
<managed-property>
<property-name>viewId</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
And :
<managed-property>
<property-name>outcome</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
With no success...
Can someone help me?
Thank you and merry christmas !

Hi,
a managed property only gives you a anlde to a bean or property, it doesn't execute it. To execute a bean, you can use a custom JSF PhaseListener that calls a bean method. The reference to the bean is achieve through value binding
ValueBinding vb = FacesContect.getCurrentInstance().getApplication().createValueBinding("Name of Managed Bean);
TypeOfBean theBean =(TypeOfBean) vb.getValue(FacesContext.getCurrentInstance());
.... theBean.theMethod() ...
