Regarding Bean scope

Hi,
I am new to this technology. I waant to know the exact approach in ADf framework in below scenario.
I have one .jspx as main screen for which i will be creating a backing bean in request scope. on that screen one pop up gets opened. For that we have different .jsff and different backing bean. what scope are we supposed to keep for the bean which is for pop up . Please help regarding this.

Hi,
Try looking into this article on bean

Bean Scope in dynamic regions

JDeveloper Version 11.2.1.3.0
In My Application i have one main URL Invoked Bounded Task flow and i have declared few beans in Pageflowscope in Managed Beans section of Overview tab.
in this main task flow i have dragged and dropped other task flows as dynamic regions based on the outcome of main task flows tab actions sub task flows will be rendered. i have achieved this task and everything is working fine.
now i want to access the page flow beans which are declared in main task-flow in this sub dynamic regions.
how i will get the reference of that main BTF page flow scope bean in the sub-task flow ?
Regards,
BK

Hi,
you will have to pass the bean as an input parameter to the task flow. Given pageFlowScope is a large scope I suggest you change the bean scope to viewScope because this is all you need. See: http://www.oracle.com/technetwork/issue-archive/2013/13-may/o33adf-1920483.html

Manage Bean Scope in Faces Config

Hi,
I would like to know if its possible to bind the bean at request level if the bean data involves multiple modifications. Currently I am facing a problem with respect to manage bean scope defination. If i keep the bean scope at request level the bean data is not availabe for modification in next request as a result I need to keep the bean at session level causing heavy loading of session object.
Can any one advice how to keep bean scope at requesat level and still the data is available for modification.

Java Bean scope when used with the JPDK

Portal 3.0.9.8.4 and Jserv
When using JSPs with Java Beans and the JPDK I have noticed problems when setting the scope attribute of the useBean action to something other than "page". For example, <jsp:useBean id="provider" scope="session" class="MyClass" /> causes a java.lang.ClassCastException when there are more than two JSP portlets than attempt to access the ProviderSession object.
Does anyone know what value the JSP scope should be set to when you want the JSPs read/write to the ProviderSession?

The behavior you report is an expected one as your keys of objects on session are not unique to the two portlet instances. Two portlets with the same session object (may have been deployed on the same Portal page), are sharing the same object put on session, thus resulting in thread conflicts. What you need to do is to generate unique keys for objects stored for each portlet instance.
For example, instead of having the id as "provider", you should have it as <portlet instance name> + "provider".
You are not experiencing the same behavior in "request" or "page" scope, as in these scopes, the objects are not shared across portlet instances.
Please let me know if my interpretation of your issue is wrong.

Abhinav

Beans scope problem

Hi
I have a bean that stores the name of the user after they have logged in. It is supposed to be in session scope
<jsp:useBean id="userInfo" class="beans.UserInfo" scope="session"/>But it appears to have been placed in application scope. It doesn't timeout and all subsequent users appear to be logged on as the first user. This is not good.
Any suggestions? I'll post the code once I've made a minimal version of the problem.
Thanks
Richard

Here's the code
the bean: UserInfo.class
package beans;
public class UserInfo implements java.io.Serializable {
private static boolean loggedIn=false;
private static String user="";
public UserInfo() { }
public static void setLoggedIn(boolean b){loggedIn=b;}
public static void setUser(String b){user=b;}
public static boolean isLoggedIn(){return loggedIn;}
public static String getUser(){return user;}
}main jsp page test.jsp
<jsp:useBean id="userInfo" class="beans.UserInfo" scope="session"/>
<jsp:include page="header.jsp" flush="true">
   <jsp:param name="title" value="Test" />
</jsp:include>
<%
boolean login=Boolean.valueOf(request.getParameter("login")).booleanValue();
if(login){
      userInfo.setLoggedIn(true);
      userInfo.setUser("strUsr");
%>
<p><b>mainpage says</b>
<%if (userInfo.isLoggedIn()) {%> <%=userInfo.getUser()%> logged in
         <%}else {%>not logged in
            <%}%>
</body>
</html>The included file header.jsp
<jsp:useBean id="userInfo" class="beans.UserInfo" scope="session"/>
<html>
<head>
<title><%=request.getParameter("title")%></title>
</head>
<body>
<p><b>header says</b>
<%if (userInfo.isLoggedIn()) {%> <%=userInfo.getUser()%> logged in
         <%}else {%>not logged in
            <%}%>load test.jsp?login=true in a browser
load test.jsp in another browser - should not appear logged in - but does at least with my system (tomcat 5.5.9 on windows xp)
Any suggestions,
Richard

Stateless Bean - scope of instance variable in EJB Timer call back function

Hi,
I would like to know on the scope of an instance variable of a Stateless Bean object,
when used in a EJB Timer call back.Let me explain this in more detail below.
I have a requirement to use a EJB Timer.
For this, I have created a stateless object since Timer creation needs to be done
from a stateless bean. I have a member variable "count" of the stateless bean class.
In the timer call back(ejbTimeout), I am able to use this count variable during
each time of the call back, and the value of this variable is also updated properly.
I have a few queries with respect to the above behaviour:
1) Does stateless bean object not get destroyed once the Timer is created from the Bean?
2) If the Bean object is not destroyed, then when does the bean object get destroyed?
3) If both (1) and (2) are not true, then can anyone explain on how the above behaviour is possible?
Thanks in advance,
Ulrich

Hi Ulrich,
The ejb timer is associated with the stateless session bean component, not with a particular bean instance. There is no formal relationship between the bean instance that called createTimer() and the bean instance on which the timer callback happens. If they're the same in your test run that's just a coincidence and not something your application should be depending on.
In the stateless session bean model, the container can create and destroy stateless session bean instances at any time. The container is free to pick any stateless session bean instance to service any client invocation or timer callback. If you need to pass context into a timer callback, one way to do it is via the timer "info" object. However, the info object is immutable so it wouldn't be a good match for a counter. You could of course always just use a database for any necessary coordinated state.

JSP - Bean - Scope Issue with ResultSet

Hi there,
I have a JSP page that uses a Bean to get ResultSets from a db. My methods return ResultSets, but they seem to get out of scope on the JSP page when I try to use them. I'm not sure why. I have included 2 snippets below one that works and one that doesn't. I get a java.lang.null exception when the page is run. Not sure how or why the variable seems to go out of scope? I can work around it, but I would rather find out why this is happening.

Regarding Bean Not found

Hi All,
I am getting this error when I try to click on the menu of my application
org.springframework.beans.factory.NoSuchBeanDefinitionException
It is a spring application.
Can anybody please let me know what could be the possible problem?
Thanks in advance.
With Regards,
Raghu

Google for the name of the [url http://static.springsource.org/spring/docs/1.1.4/api/org/springframework/beans/factory/NoSuchBeanDefinitionException.html]exception and you'll learn the meaning of it.
You'll discover that somewhere after you mouseclick a BeanFactory cannot find the bean you referenced by name in < ref bean='xyz' >.

Handling Session in jsp and bean scope

i have problems with handling session in jsp
I want to check on all jsp pages
first thing is session is null
i want to him to be redirected to first page
and he should not be able to go ahead
I tried
if(session ==null)
response.sendRedirect("Login.jsp");
but this does not seem to work
It is very crtical problem can any one answer
this asap
Also i wanted to know that
I have bean which in turn calls static methods of another class which holds all DomainTable(database tables which do not change frequently)
Information .
This is bean is being implemented by me
in seession scope in a jsp
Do u guys think it would be goo idea to change
scop of this bean as Application in jsp
if so what would be advantages for same
I would appericate if i could a quick reply on both
question
as i am time crunch
arsh

You will always get some value of session and your code wont work. At the end of your Login.jsp, you should create a sesssion and store attributes. Check for these attributes in session, rather than checking session==null.

Query regarding the scope of a page

hi all
i have problem with scopes of the pages.I have a data entry page where i have a button to add address.When i click on address button it will go to another page where i can add the address.After adding it returns to the entry page.The problem is that when it returns all the data entry feilds are cleared.Is there any way to restore the states of the textfields and other componenets.Please help me
Thanks in advance
Sree

Yes there is. Store the values in managed bean properties and, in the prerender method, set the component values to the values from the managed bean properties.

Regarding SLIN scope

hi guys,
Do SLIN/SCI programs check for below errors too?
1-BAPI related errors
2-ABAP Query related errors
3-SAPSCRIPT/SMARTFORMS errors
4-IDOC related errors.
Please suggest if any alternatives to find the upgrade error exist in programs using above.
Thanks.
Ambichan.

Hi,
You use this function to perform static checks, which are too time consuming for the normal syntax check. The extended program check returns both errors and warnings and it is possible to run either individual specialized tests or one whole standard check.
It check only for Reports, Module Pools, Class & Interfce.

And using in template title by using #{sessionScope.u_name}

Does a getId() on the forwarded page and the page forwarded from return the same value?

ADF Faces and BC: Scope problem with managed bean

Hi,
I am using JDev 10.1.3 and ADF Faces with ADF BC.
I have created a managed bean which needs to interact with the binding layer and also receive actions from the web pages. I have a managed property on the bean which is defined as follows:
<managed-bean>
    <managed-bean-name>navigator</managed-bean-name>
    <managed-bean-class>ecu.ethics.view.managed.Navigator</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
      <property-name>bindings</property-name>
      <value>#{bindings}</value>
    </managed-property>
</managed-bean>I need the been to session scope because it needs to keep previous and next pages to navigate the user through their proposal. If i use session scope (as above) i get the following error when i click on a comand link which references a method in the above bean: #{navigator.forwardNext_action} which returns a global forward.
this is the exception:

Hi pp,
you need to create a managed (not backing) been set to session scope.
You can call/reference the managed bean from your page.
the backing bean is designed around a page lifecyle which is request oriented in it's design.
This is a simple managed bean from faces-config.xml
<managed-bean>
    <managed-bean-name>UserInfo</managed-bean-name>
    <managed-bean-class>ecu.ethics.admin.view.managed.UserInfo</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>
</managed-bean>and the getters and setters for bindings in your session scope managed bean:
    public void setBindings(BindingContext bindings) {
        this._bindings = bindings;
    public BindingContext getBindings() {
        return _bindings;
    }you can access the model from the managed bean using the the BindingContext if needed.
also have a look at JSFUtils from the ADF BC SRDemo application, there are methods in this class such as resolveExpression which demonstrate how to get the values of items on your page programatically using expression language. You can use this in your managed bean to get values from your pages.
