Access managed beans in action methods

Hi,
I am a newbie in JSF. In my first page, I am getting input from the user and pass it to my business object for processing. My Business Object returns some results and i want to show it in page 2 which has a different backing bean. So I am accessing the bean as follows:
FacesContext Ctx = FacesContext.getCurrentInstance();
Map Params = Ctx.getExternalContext().getSessionMap();
ResultBean rbean = Params.get("MyResultBean");MyResultBean is registered to have session scope in my faces-config file and is the backing-bean for my page 2.
Then i set the results in rbean and forward to the page 2.
Is this the right way of doing? Or are there any other way of doing it?
Need your valuable suggestions.

By the way, why are you using capitalized variabe names? It makes them unreadable .. I am referring to Ctx and Params.
This is Java, not C# or so ;)

Accessing Managed Bean Variables in Entity Impl Class

How can I access managed bean variables in the entity Impl class .
While inserting a new record in DB , i want to set few entity properties values . The values of those properties are available in the managed bean .
How can i access those values from Managed Bean and set them the entity Impl class to override the create method.
Or is there any better recommended approaches ?

Accessing Managed Beans from Code

Hi,
How can I access managed beans from my code? I am too new to JSF to know if what I am doing is right from a design perspective. But what I am trying to do is to use Actions as sort of a Web Facade that aggregates state from other beans (all of them Managed beans right now) to build up state that is necessary for displaying pages.
Thanks for you help
Suhail

Just answering my own question. The answer was given in a different thread (http://forum.java.sun.com/thread.jsp?forum=427&thread=427057&message=1901909#1901909) . JSF has provided various Factories (look at the FactoryFinder API) that allow one I presume to access the internal state of a FacesContext. One of the factory is ApplicationFactory. This factory from what I can make out essentially gives you access to everything (actionlisteners, navigationhanlder,components etc) in you application. My original question was about accessing something (for some reason) named ValueBinding. I can access the managed beans declared in my faces-config.xml by invoking getValue(facesContext). I can naturally also set the value of a bean by invoking setValue(...). I just needed the getValue and it seems to work.
Ofcourse keep in mind that the underlying managed bean will not necessarily be initialized when you access it so test for nullness. As a general rule I think its best not to create the beans but access them using this facility. After all its not for nothing these are called Managed Beans.
Now if only the faces implementation would persist the changes to Navigation hanlders that one makes in the code ;-)

Accessing managed-bean in a JSP (portal theme).

I have a tricky situation where I need to access a managed-bean outside a JSF jsr 168 api portlet. Now I need to reference the bean in the themes jsp (just fyi themes loosely relate to JSP's which control the look and feel, navigation within portal page). I was thinking of a way to set a managed-bean variable in the jsp before the portlet where the managed-bean is declared. Is this possible ? Any ideas ?

You can just access managed beans using JSTL EL.${myBean}or if you strictly want to specify the scope, e.g. session scope${sessionScope.myBean}where "myBean" is the managed bean name. Keep in mind that you cannot use this in input elements, but only in output elements. If you want to use this in input elements, then you should be using JSF components with deferred EL #{myBean.input} and so on.

Can't get JSF to access managed bean methods from web page

I'm using NetBeans 6.7.1 and Glassfish v2.1
Having problems here can somebody please help? It is really
frustrating because I have written apps like this before in fact I
used one as a model to create an even simpler app and still can't get
it to work. I ran it through the debugger and it stops in the
constructor so it looks like the bean object is being created, but the
setUid method and the testit method are not being entered when I click
on the enter commandbutton. Can somebody PLEASE give me an idea as to
what might be going on? I am totally stumped and this is holding up
some important work I need to get done. Any help would be greatly
appreciated:

Reset Managed Bean in Action Servlet?

I've searched through the forum and have came close in finding the answer however the recommended solution is not working...
How can I use this code:
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove("beanName");to reset a managed bean in an Action Servlet?
How can I get the managed bean in the Action Servlet and reset it?
I'm not after getting the HttpSession and invalidating it. I would just like to reset the managed bean in the servlet.
Thanks!

@RaymondDeCampo, Does resetting the managed
bean same with resetting the session?If you remove the bean from the session, using traditional servlet APIs, it will appear to JSF as an uninitialized managed bean. When the application uses it next, JSF will instantiate it and set the properties as normal.

Accessing managed-beans property from simple java class

I have managed bean that is registered in faces-config.xml:
<managed-bean>
<managed-bean-name>documentReportsBean</managed-bean-name>
<managed-bean-class>[myApp].beans.DocumentReportsBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
I want to access property of documentReportsBean from other java class without registering managed-property in faces-config. How can I do that?

Thank you, what I needed was someone saying the right word. "ValueBinding" in this case.. :)
Two lines:
ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding("#{documentReportsBean}");
DocumentReportsBean pbean = (DocumentReportsBean) vb.getValue(FacesContext.getCurrentInstance());
gives my full control. Nice

How to clear the value of a variable in a managed bean after AM method...

I have two inputText fields on a page - user inputs a value in FieldA and performs a search (execute w/ params)... FieldB shows up under Results table with an 'Add' button. User can enter a value in FieldB and click 'Add' to insert a new row in the Results table.
I got the insert to work by making FieldB binding = #{userState.newVisitorId} where userState is a session scoped bean.
When the page reloads after the insert, the value entered in FieldB is still there - I want to clear it out. I know 'marrying' the AM code for the insert to the View code for the bean is bad practice; what is a better way to do this?
Thanks!

For anyone who might also be looking for this solution... I simply added a SetActionListener to the 'Add' button that was set as From: #{null} To: #{userState.newVisitorId} and it works like a charm.

Action method calls when refreshing the JSF page

I have a test application which contains a JSF page. The page contains a command button. Button's action attribute is mapped with action method in managed bean.Inside action method I am not doing anything and just redirecting to the same page using navigation-rule configured in faces-config.xml. I deployed the application and tested the page.
This is what I observed.
scenario 1:
===========
1) Run the page.
2) Refresh the page.
Observation:
Action method not called.
scenario 2:
===========
1) Run the page.
2) Click the command button.
2) Refresh the page any number of times.
Observation:
For each and every time the page is refreshed Action method is called.
Can anybody tell me why it is happening?

You get the page using a http get so no action is "configured" to fire...

Operation not found error while calling AM methods from managed bean

Hi,
operation not found error while calling AM methods from managed bean.
written a method with two parameters in AM.
exposed the method in AM client interface
in the page bindings added the method in method action ..left empty in the value fields of the parameters.
calling the method from managed bean like below
String userNameVal = (String)userName.getValue();
String passwordVal = (String)password.getValue();
OperationBinding operationBinding =
ADFUtils.findOperation("verifyLogin");
operationBinding.getParamsMap().put("userName",userNameVal);
operationBinding.getParamsMap().put("password",passwordVal);
operationBinding.execute();
i am getting operation verifyLogin not found error.Please suggest me something to do.
Thanks
Satya

Hi vlsn,
Can you try with the below code
// in your backing bean
OperationBinding operation = bindings.getOperationBinding("verifyLogin");
//Put your both parameters here
operation.getParamsMap().put("parameter_name1", parameterValue1);
operation.getParamsMap().put("parameter_name2", parameterValue2);
operation.execute();
if (operation.getResult() != null) {
Boolean result = (Boolean) operation.getResult();
and share the result.

Rajan

Unwanted behavior: Action method being called several times

Hello,
I have a managed bean that calls a session ejb which itself does a search. The problem is that it is supposed to retrieve a resultset ONCE and the displayed behavior is that it never stop doing so. It fetches the resultset N TIMES.
Here is the managed bean and the method to look at is the performSearch method:

Password ending with % "hangs" access manager

Dear Guru's
We are running Sun Access Manager 7.1. We encountered a problem when users try to login with a password ending with the character "%".
One way or another, the access manager calls the URLDecodeField method of com.iplanet.am.util.Locale twice. This results in a loop in this method.
Can anyone help me how to get rid of this problem?
Thanks in Advance

Ideally you would use SAML or Federation between the Access Manager server and WAS portal. I don't know enough about WAS portal to know if that is supported or not.
Sun has a policy agent for WAS 6.0 and the WAS PA can be configured to use the AM as a user repository. With AM7 you could try two different realms with two different data stores and have AM authenticate against one realm and the PA use the other realm and see what happens.
Passing around user credentials between applications is a security issue and you should avoid it if possible.

How to invoke action method from mail contained link

Hello,
my application needs to send mails to users that include links for the user to click on. Something like www.mysite.com/displayData.jsp&id=123. My question is now how I make JSF invoke the respective method in the backed bean to display the data with the id 123 when the user clicks on the link int the mail.
I wonder whether there is some kind of "catch-all action" that checks whether the user is logged in and authorized whenever any JSP page is invoked. I'm a bit tired of first checking the authorization of some user before processing the remaining part od the backed bean's action method.
Thanks for any hints,
Oliver Plohmann

my application needs to send mails to users that

Managed Bean "Name" Access with in the Managed Bean

Hi,
I have faces-config.xml in which I have registered a managed bean
and I have a base class for all the managed bean.
The JSP's invoke the action/method defined in the base bean and I want to remove the managed bean from session upon a particular event.
To remove the managed bean from session, as far as I know - we need to know the managed-bean-name in the faces config.
I wanted to know if there is any way to get the name of the managed bean in the faces-config.xml at run time?.
Thanks,

Thanks for your recommendations. The issue that I get stuck on is how to call this method that retrives employee data. When I had the code in the constructor, it executed when I accessed the view.jsp page. Then I populated the fields from the Employee class fields. But once I create non-constructor method, how do I invoke it from my JSF page.

Managed Beans and Data Access Object

I have a question / need help understanding how to configure backing bean and model objects so that memory and object creation/deletion is done as efficiently as possible.
1. I have a .jsf page with a form and a commandbutton that submits the form inputs to a backing bean (enrollispbean is backing bean)
<h:commandButton value="Enter" action="#{enrollispbean.insert}"/>
2. The backing bean is used for form handling - the insert() method is used to read the data fields from the form and create a SQL string that will be submitted to a model object, DbInsert, that is used as a generic data access object that connects to the database and insert the SQL string:
public class EnrollIspBean {
private String beanvar1="";
private String beanvar2= "";
// DbInsert is data access object
private DbInsert dbinsert = new DbInsert();
public String insert (){
String sqlstmt;
sqlstmt = "INSERT INTO ispmain VALUES(beanvar1, beanvar2,..)"
dbinsert.insert(sqlstmt);
return "success"; }
3. DbInsert is the data access object that contains a method, insert(), that accepts a sql string to insert into the database. This method contains the code to obtain a connection from the database connection pool and then execute the sql statement (note: error checking code not shown):
public class DbInsert {
public void insert(String sqlstmt) throws SQLException {
Connection conn = null;
GetDBConnection getdbconnection = new GetDBConnection();
PreparedStatement stmt = null;
conn = getdbconnection.getdbconn();
stmt = conn.prepareStatement(sqlstmt);
stmt.executeUpdate();
stmt.close();
conn.close();
return;
Where I need help understanding is how to set up the scope for the managed beans and data access object. Currently, I have the backing bean within the session scope (using the facesconfig.xml file). My main question is how to set up the scope for the Data Access Object - currently I do not have it as a managed bean within facesconfig.xml. Instead I am creating a new instance within the backing bean:
private DbInsert dbinsert = new DbInsert();
Is this the best way to do this? Will the DBInsert object now be tied to the session scope of the backing bean (i.e., when backing bean is deleted, the DbInsert object will be deleted from session scope as well.)
Ideally I would like the data access object to be available as a shared object throughout the life of the application. When I was programming using a servlet approach, I would have created a servlet to load on startup. Now that I'm using java server faces, I'm confused about the scope / how to efficiently set up a data access object that I want to be available to all backing beans in the application.
tnanks for any help understanding this.
Tom

I was thinking about setting the data access object as application scope so that it can be used by an backing bean to execute sql statements.
If I do set it as application scope, however, if I do this, do I still need to declare a new instance of the object from within each bean that uses the object?
For example do I need to declare a new instance of the data access object from within the bean? or, should I assume that there is always an instance of the bean available in the application scope, and if so, how do I reference it from within the bean?
Bean Code:
public class EnrollIspBean {
// DbInsert is data access object
private DbInsert dbinsert = new DbInsert();
Finally, I understand performance may be an issue if I have one instance of the data access object available in the application scope - is there a way to make multiple instances available in the application scope?
thanks
