JSF1063 Warning With Managed Bean
With Glassfish V3 it outputs a JSF 1063 warning to do with not being able to serialise an object. Below is the Glassfish log:
INFO: Instantiated an instance of org.hibernate.validator.engine.resolver.JPATraversableResolver.
INFO: nullID: /home/nick/NetBeans Projects/EAA Website/build/web/ CLASSES: [class nz.co.eaa.FeedbackController, class nz.co.eaa.ServicesController, class nz.co.eaa.Feedback, class nz.co.eaa.ApplicationController]

WARNING: JSF1063: WARNING! Setting non-serializable attribute value into HttpSession (key: feedback, value class: nz.co.eaa.Feedback).What is really bizarre is that the managed bean (Feedback) is session scoped, therefore it should be serialised across a session (HTTP session). Also the managed bean has a null ID which may contribute to the problem. Here are the contents of Feedback.java:
package nz.co.eaa;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean(name = "feedback")
@SessionScoped
public class Feedback
private String firstName = "";
private String lastName = "";
private String email = "";
private String phoneNum = "";
private String address = "";
private String subject = "";
private String message = "";
private String priority = "";
/** Creates a new instance of Feedback */
public Feedback()
// Do nothing.
public String getAddress()
return address;
public void setAddress(String address)
this.address = address;
public String getEmail()

</html>Currently when feedback.xhtml is visited nothing is saved to the HTTP session even though feedback's properties are bound to the JSF controls in feedback.xhtml. Has anyone encountered a similar problem where a session scoped managed bean is not persisted in a HTTP session?
Interesting that the container would attempt to persist a session to disk, or some other persistent storage if the session times out. This would explain why there was a warning message that appeared in the Glassfish log. Below is the contents of FeedbackController.java:
package nz.co.eaa;
import java.util.HashMap;
import java.util.Map;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.NoneScoped;
@ManagedBean(name = "feedbackController")
@NoneScoped
public class FeedbackController
private Map<String, String> labelNames = new HashMap<String, String>();
private String[] subjects = {"Inquiry", "Comment", "Quotes"};
private String[] priorities = {"Low", "Medium", "High"};
/** Creates a new instance of FeedbackController */
public FeedbackController()
labelNames.put("firstName", "First Name:");
labelNames.put("lastName", "Last Name:");
labelNames.put("email", "Email:");
labelNames.put("phoneNum", "Phone Number:");
labelNames.put("addr", "Address:");
labelNames.put("subject", "Subject:");
labelNames.put("msg", "Message:");
labelNames.put("priority", "Priority:");
public String[] getPriorities()
return priorities;
public String[] getSubjects()
return subjects;
public Map<String, String> getLabelNames()
return labelNames;
}As for FeedbackController it is set for None scope since some data is contained within the managed bean itself. All data bindings to the FeedbackController are receiving the correct values so this isn't the actual issue. The real issue is data not being retrieved from Feedback when it is filled with data (supposedly), hence all form data is lost when feedback.xhtml is refreshed.
Although this may not be needed I have included the contents of web.xml below just in case:

Problems with managed beans on included JSPs
I've got a problem with managed beans within an included JSP
The included page looks as follows:
<f:subview id="includedPage" binding="#{testBean.component}">
<h:outputText value="Hallo from the included page"/>
<h:outputText value="#{testBean.msg}" />
</f:subview>The including page is also very simple
<f:view>
<html>
<head>
<title>Test include</title>
</head>
<body>
<h:outputText value="Hello from the including page"/>
<jsp:include page="included.jsp"/>
</body>
</html>
</f:view>The testBean is a managed bean with page scope and looks as follows:
public class TestBean {
public UIComponent fComponent;
public TestBean() {
System.out.println("TestBean Constructor called " + toString() );
public String getMsg() {
return "Component = " + fComponent ;
public void setComponent(UIComponent component) {
System.out.println("setComponent called " + component);
fComponent = component;
public UIComponent getComponent() {
System.out.println("getComponent called " + fComponent);
return fComponent;
}The output to the console is:
TestBean Constructor called de.kvb.athena.web.beans.TestBean@1bc16f0
getComponent called null
TestBean Constructor called de.kvb.athena.web.beans.TestBean@18622f3
setComponent called javax.faces.component.UINamingContainer@160877b
TestBean Constructor called de.kvb.athena.web.beans.TestBean@5eb489
and the page displays
Hello from the include page
Hello from the included page Component = null
Can anyone explain this behavior ? What's the reason that the page displays
Component = null
and is it possible to display the parent naming container (subview) this way ?
how ?
ThanksBy "page scope" I assume you mean "none"? If so JSF creates a new bean for each place it's referenced. The closest to the behavior you want, once per "page", is really request scope.
(I'm not sure why the constructor is being called thrice, though. I should look into this.)
I assume you want a bean-per-subview scenario. This should be doable, and one way that allows a dynamic number of subviews would be as follows:
--create a "manager" bean in request scope
--give it get/set methods that retrieves a Map of "TestBean" instances; the idea is that each subview use a different key "s1", "s2", etc
back the manager method with Map implementation that checks if there's already a TestBean associated with the key returns it if yes, else null.
If that seems messy, the component solution is hairy :-) See http://forum.java.sun.com/thread.jspa?threadID=568937&messageID=2812561

Action / actionListener in h:commandButton with managed beans
I have a problem with a backing bean whose method is not invoked when i click it. I've seen some posts on here about this yet, I still don't understand what I am doing wrong, if anything.
Some context...I've modeled my application after 'jcatalog' from this article:
http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html . It's simpler than the article -- I'm not using Spring/Hibernate and the persistence is the file system. For each business object (Resource), there's a backing bean (ResourceBean).
In short, I can't get the backing bean to respond to the button event for 'Add' bound to addAction. This is just like the jcatalog 'createProduct' impl -- which doesn't use the (FacesEvent fe ) approach.
Anyway, I would appreciate anyone's help to get past this.

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:
javax.faces.FacesException: #{navigator.forwardNext_action}:
javax.faces.el.EvaluationException: javax.faces.FacesException:
javax.faces.FacesException: The scope of the referenced object: '#{bindings}' is shorter than the referring object at

BrendenHi 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.
regards,
Brenden -
Best practices with managed bean
Hi, I have 7 jsf which have 4 listaschoice and checkbox all use the same.
the difference is that when running the action of the button, going to run a different, now I have one for the 7 jsf bean and the only thing that changed is the method of action of the button, which I recommend, I say use every jsf by beanthanks,
another question, you have experience in adf, I wonder if this framework has the ability to run processes pl/sql,
as this I'm doing everything with button actions, and execute the method that executes the process, for example:
public String buttonfagepr() { //Generacion de procesos(detalles) fagepr.jsf
String vaProceso = "Generacion de procesos";
String vaProcedimiento = "ARQU.mbfacturacion.fnuProcFact";
String vaTipo = "S";
String modulo = "FA";
String[] datosGenXML = new String[2];
//"IdParametro", "TipoParam", "TipoDato", "Order", "Value"
//System.out.println(this.periodo);
datosGenXML[0] = "c#,#IN#,#NUMBER#,#1#,#" + super.getPeriodo();
datosGenXML[1] = "mensajeError#,#OUT#,#VARCHAR2#,#2#,# ";
ArqUtils.procedures(vaProceso, vaProcedimiento, vaTipo, modulo, datosGenXML);
return null;
I want to know if the framework has the option of running processes pl / sql ...thanks timo -
Setting bind variable for a view object from the Managed Bean
Hi,
i am using JDeveloper 11g, i have to create LOV in the JSF. To show the LOV, it has to populate data using View object and its query parameter need to be sent from the Managed Bean.
For the View object i want to set the bind variable parameter from the managed bean value. bename is stored in a managed bean (session scope)
#{beantest.bename}
But it gives the following exception.
JBO-29000: Unexpected exception caught:
org.codehaus.groovy.control.MultipleCompilationErrorsException,msg=startup failed, Script1.groovy: 1: expecting '!',found '{'@ line1, column 2.
I have followed the link http://kr.forums.oracle.com/forums/thread.jspa?threadID=615474 like Frank wrote on 8.2.2008:
But steps are not clear.
How to input the VO bind parameter with Managed bean variable?
Any Help
Regards
Raj
Edited by: user9928180 on Dec 17, 2008 9:51 AMHi,
a bind variable in a VO needs to be exposed as an executeWithParams operation in the pageDef file. Just add a new action binding to the pageDef file (context menu) and select the executeWithParams operation on teh VO. Then in the argument field, reference the managed bean property for the value

Hi
Are there any best practices for using Managed Beans?
We plan to use our own custom-built JSF components. Need to understand how to design backing beans for performance/effort optimization.
For example :
1. How to make managed beans thread-safe for concurrent requests, without compromising on efficiency/speed?
2. How to enforce the J2EE security with managed-beans?
3. How to decide the scope of these beans to ensure minimal data-storage in session?
4. How to decide the granularity at which a managed-bean should be used for example :
4.1 One bean-per-component
Advantages :
a) if complex components require special data-holding/processing/event-handling capabilities from bean
(e.g. datagrid model,tree model,menu model)
Problems :
- with multiple components in a page/form
a) it becomes tedious to debug/change/track which bean serves which component
b) if session scope is required, too many beans will be cached in session
c) unnecessarily too many beans will be created on server (= n pages * m components-per-page)
d) unnecessarily increases the length of faces-config.xml
4.2 One bean-per-form
Advantages :
a) in multi-form web pages, to ensure the functional behaviour of each form is separate/modular in its own bean.
b) each managed-bean would map to specific/meaningful functionality/user-interaction in use-case.
Problems :
- if form includes complex components (datagrid/tree/menu) requiring a specialised bean class, then
a) either one of the specialized bean has to be augmented with additional logic to handle data/events for all other components within the form
(Not good, as it mixes-up the responsibilities of component-specific-beans, and the bean may no more be reusable in another form)
b) or without using component-specific beans, only single form bean should handle the data/events for all components in the form?
(Neither good, since if a complex tree-compoent is reused in multiple forms, then the logic to handle data/events for such a component will be repeated in those many form-specific managed beans)
4.3 One bean-per-page
Advantages :
a) seems more modular/meaningful way - since a page would map to some feature within the use-case
b) bean will contain only behaviour which is relevent for the associated page/function within use-case
Problems :
a) in multi-form pages, can single bean handle data/events for multiple forms?
b) if page uses complex component (e.g datagrid, tree) that needs its own bean - how does page-bean exchange data with component-bean?

ArtiAre there any best practices for using Managed
Beans?There are no best practices for using Managed Beans in terms of Sun, or other vendors recommendations. But there are some patterns that can be applied to the managed beans (The managed bean is already a pattern). Also common sense is allways a good practice.
For example, the managed bean should not have business logic code, only presentation logic code, etc.
1. How to make managed beans thread-safe for
concurrent requests, without compromising on
efficiency/speed?The beans can be created by request, so concurrency is not an issue. If they are session scope, also is not an issue because, a user can only have one thread running. Only in application scope you must have carefull.

2. How to enforce the J2EE security with
managed-beans?see this:
http://jsf-security.sourceforge.net/
About jsf-security
>
3. How to decide the scope of these beans to ensure
minimal data-storage in session?If you wnat minimal data-storage in session the answer is request or none.
In question 4, you make the question and give the answer ;-) -

Query with bind variable, how can use it in managed bean ?
Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
ThanksPut the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page. -
Generate PDF using Managed Bean with custom HTTP headers
Background
Generate a report in various formats (e.g., PDF, delimited, Excel, HTML, etc.) using JDeveloper 11g Release 2 (11.1.2.3.0) upon clicking an af:commandButton. See also the StackOverflow version of this question:
http://stackoverflow.com/q/13654625/59087
Problem
HTTP headers are being sent twice: once by the framework and once by a bean.
Source Code
The source code includes:
- Button Action
- Managed Bean
- Task Flow
Button Action
The button action:
<af:commandButton text="Report" id="submitReport" action="Execute" />
Managed Bean
The Managed Bean is fairly complex. The code to `responseComplete` is getting called, however it does not seem to be called sufficiently early to prevent the application framework from writing the HTTP headers.
HTTP Response Header Override
* Sets the HTTP headers required to indicate to the browser that the
* report is to be downloaded (rather than displayed in the current
* window).
protected void setDownloadHeaders() {
HttpServletResponse response = getServletResponse();
response.setHeader( "Content-Description", getContentDescription() );
response.setHeader( "Content-Disposition", "attachment, filename="
+ getFilename() );
response.setHeader( "Content-Type", getContentType() );
response.setHeader( "Content-Transfer-Encoding",
getContentTransferEncoding() );
Issue Response Complete
The bean indirectly tells the framework that the response is handled (by the bean):
getFacesContext().responseComplete();
Bean Run and Configure
public void run() {
try {
Report report = getReport();
configure(report.getParameters());
report.run();
} catch (Exception e) {
e.printStackTrace();
private void configure(Parameters p) {
p.put(ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put(ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put(ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put(ReportImpl.SYSTEM_REPORT_PATH, "/reports/rwservlet");
p.put(Parameters.PARAM_REPORT_FORMAT, "pdf");
p.put("report_cmdkey", getReportName());
p.put("report_ORACLE_1", getReportDestinationType());
p.put("report_ORACLE_2", getReportDestinationFormat());
Task Flow
The Task Flow calls Execute, which refers to the bean's `run()` method:
entry -> main -> Execute -> ReportBeanRun
Where:
<method-call id="ReportBeanRun">
<description>Executes a report</description>
<display-name>Execute Report</display-name>
<method>#{reportBean.run}</method>
<outcome>
<fixed-outcome>success</fixed-outcome>
</outcome>
</method-call>
The bean is assigned to the `request` scope, with a few managed properties:
<control-flow-rule id="__3">
<from-activity-id>main</from-activity-id>
<control-flow-case id="ExecuteReport">
<from-outcome>Execute</from-outcome>
<to-activity-id>ReportBeanRun</to-activity-id>
</control-flow-case>
</control-flow-rule>
<managed-bean id="ReportBean">
<description>Executes a report</description>
<display-name>ReportBean</display-name>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
The `<fixed-outcome>success</fixed-outcome>` strikes me as incorrect -- I don't want the method call to return to another task.
Restrictions
The report server receives requests from the web server exclusively. The report server URL cannot be used by browsers to download directly, for security reasons.
Error Messages
The error message that is generated:
Duplicate headers received from server
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.Nevertheless, the report is being generated. Preventing the framework from writing the HTTP headers would resolve this issue.
Question
How can you set the HTTP headers in ADF while using a Task Flow to generate a PDF by calling a managed bean?
Ideas
Some additional ideas:
- Override the Page Lifecycle Phase Listener (`ADFPhaseListener` + `PageLifecycle`)
- Develop a custom Servlet on the web server

Thank you!The problem was that the HTTP headers were in fact being written twice:
1. The report server was returning HTTP response headers.
2. The bean was including its own HTTP response headers (as shown in the question).
3. The bean was copying the entire contents of the report server response, including the headers, into the output stream.
Firefox ignored the duplicate header errors, but Google Chrome did not. -
How to call a AM method with parameters from Managed Bean?
Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you

Reset JSF session and the managed beans with sesison scope
Hi,
this is a very general question and maybe stupid for most of you. I have my jsf/facelets web application and i use inside of this application some managed beans, which are session beans. I want to know how is it possible to reset this beans. I'm asking this question beacuse i have this kind of problem: i built my web application which has a login form and i use the browser to test it. When i browse to the login page and I login with my credentials i get my customized home page. Then i open another istance of the browser and i browse to the login page again but this time i login as a different user. The result home page is the same as i got before with my login credentials, so the session is always the same. Instead i want the session and all its objects to be resetted for the new user! Do youn know which is the solution?The fact is that i want to have two sessions in parallel, so using the same browser and opening two tabs, i want to browse to the login page and access as two totaly different users and using in parallel the application without the problem of one user's action affecting the other user beacuse of session sharing. So I want to force the application to create two different session for the two users logins, because as i told you before as it is now, they are sharing the same sesison. And i think that if i at the login time I iterate thorugh the session and delete all the objects i will be able to have only one session per time. Isn't it?

Share stateful session bean in JSF managed beans with different scope
Hi,
I have a JSF application and I want to try to use of stateful session beans.
So I created a new stateful session bean and its local interface.
@Stateful
public class StatefulSessionBean implements StatefulSessionBeanLocalInterface{
private String name;
@Local
public interface StatefulSessionBeanLocalInterface {
...In my JSF application I have a mananed bean with session context which registers the new interface by
this annotation
@EJB(name="sessionbeanref", beanInterface=StatefulSessionBeanLocalInterface.class) and set the name to something.
Now I want to fetch this name in another managed bean with request scope. So I looked up the bean and tried to get the name.
StatefulSessionBeanLocalInterface = (StatefulSessionBeanLocalInterface) new InitialContext().lookup("java:comp/env/sessionbeanref");
System.out.println(currentmailingbean.getName());but the name is null.
Why?The xsd was created via the netbeans J2EE enterprise application dialog and I think its the most recent.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">All other annotations seem to work.
Wouldnt the lookup completely fail if the deployment process thought that it is version 1.4 ? -
JDeveloper gets slow with a lot of managed beans declared in faces-config
Hello,
I have an application with a lot of managed-beans (in fact, hundreds of backing beans). When I open the visual designer, it takes a long time to render the page, and after it gets very slow. Even the source view gets slow. When I remove some parts of these managed beans, JDeveloper back to normality.
The problem is that the JDeveloper is so slow that I just can not do anything in JSPs.
Anyone have any idea?
I am very grateful for any help.
Thanks.
Edited by: gutogarcia on 22/01/2010 09:33ThDn,
You can avoid adding unnecessary getters and setters of UI components in backing bean by selecting the option "Do not automatically expose UI Components in a Managed Bean" option when creating the Page.
The nice thing is that in JDev 11g and in latest version of JDev 10g this option is selected by default when creating new pages.
However in older JDev 10g versions the default was "Expose UI Components to a Managed Bean" so if developer did not change it during page creation it is possible that there would have been lots of unnecessary getters and setters in the backing bean.
Luiz,
As you say that this was fine in TP4 it could be that in newer JDev version there might have been added some new feature that caused this slowness.
When you remove unnecessary getters/setters from you backing beans, you will have to modify the JSPs and remove the bindings from the UI components as well.
Thanks

To dynamically assosciate an iframe with a new managed bean instance
I have a datatable populated with records.Each row consists of a checkbox and the corresponding row data. I need to select 2 rows to display the same in 2 different iframes rendered in the next page. I have one managed-bean (Display.java) registered in the faces-config.xml in the session scope. But I would like to assosciate each iframe with a different instance of Display.java. Is it possible?
Now, I have each iframe assosciated with a different instance of managed bean.
Also the requests are distinguished based on the rowId appended as a
parameter to the querystring.
eg:<IFRAME src="display.jsf?rowId=1">.
The iframes are drawn dynamically based on the no of rows selected.
But there is a mixup of data, i.e the first row data appears in both the iframes. Is it to do with rendering of iframes? How do i resolve this?
