Custom method and Backing Bean

Hi,
I have created a custom method in my application for creating a record in table "TEST".
I then dragged the method on a jspx page and created a parameter form.
The method has some parameters, for example parameter1, parameter2,....parameter10.
One of the parameters i have specified it as a selectOneRadio. Based on what the user selectes, i want to hide/show some parameters.
What i would like to do is to be able to access the selectOneRadio from a bean, and then access the other parameters so to set render option to true/false based on the selection.
Thanks
Antonis

Hi,

Calling a method on backing bean in response to contextual event

Hi
I am using Jdeveloper 11.1.1.6.0 and using ADF contextual events..
I have a drop down list and i am rasiing a contextual event on changing the current selection. In response to that event i want to call a backing bean method with parameters.. But when i click on the subscriber section for the contextual event, i can see only some bindings of the page.. How can i call a method on backing bean as a subscriber..
Thanks
Raghu

Hi,
this article has a use case for the POJO approach: http://www.oracle.com/technetwork/issue-archive/2011/11-may/o31adf-352561.html
Another is to define a method binding in the receiving PageDef file and configure it as explained here

How to call a method in backing bean on hitting 'Enter' key on a page.

Hi all,
I would be obliged if any one can provide me solution for the below given problem.
My requirement is to call a method in backing bean when i hit 'Enter' key on a JSP page.
I am trying this by using a script given below.
*function fnChangeFocus(){*
*if(window.event.keyCode==13){*
* document.getElementById("mainform:submitForm:commandbutton").focus();*
The JSP has the textbox as given below.
*<h:inputText id="inputtxtboxid" disabled="false" value="#{Bean.inputvalue}"*
onkeypress="fnChangeFocus()" size="24" />
Using this I could not acheive the required functionality. Please suggest some alternative.
Thanks,
Jagadeesh Pala

Only a form element supports the submit() function. Make sure that the getElementById returns the appropriate form. Or rather pass the element as the 'this' reference to the function and get the parent form from it.
After all this is just basic DHTML / Javascript+DOM knowledge and in fact this has nothing to do with JSF. For future basic DHTML / JS+DOM questions you may take a look at the appropriate forums, e.g. dhtmlcentral.com, dynamicdrive.com, etcetera.

What is difference between Managed Bean and Backing Bean?

What is difference between Managed Bean and Backing Bean? Please guide me how to create them and when to use them?
Please post sample for both beans.

Hi,
managed beans and backing beans are quite the same in that the Java object is managed by the JavaServer Faces framework. Manage in this respect means instantiation. The difference is that backing beans contain component "binding" references, which managed beans usually don't. Do backing beans are page specific versions of managed beans.
Managed beans are configured either in the faces-config.xml file, or using ADF Faces and ADFc, in the adfc-config.xml file

How to create the custom method and make it available to clients:

Hello, Can any one help me with this problem ASAP??
I am trying to work on an example of "Customizing the Query and Creating an Associated Custom Method"
from http://helponline.oracle.com/jdeveloper/help/topics/jdeveloper/developing_mvc_applications/adf_pviewcustommethod.html?tp=true#method. To do that, the first task is to create the custom method and make it available to clients.
Following instructions in the helponline documentation, I completed the three steps: (1) "Specify a custom query for the View Object definition for EmployeesView", (2) "Add the custom method to the application module Java class", and (3) "Make the method available to clients".
The following is the error message I got to test the application module. Can anyone tell me what the message really means and what I should do. I am wondering if there is any mistakes in the document.
(oracle.jbo.SQLStmtException) JBO-27122: SQL error during statement preparation. Statement: SELECT Employees.EMPLOYEE_ID, Employees.FIRST_NAME, Employees.LAST_NAME, Employees.EMAIL, Employees.PHONE_NUMBER, Employees.HIRE_DATE, Employees.JOB_ID, Employees.SALARY, Employees.COMMISSION_PCT, Employees.MANAGER_ID, Employees.DEPARTMENT_ID FROM EMPLOYEES Employees WHERE Employees.SALARY > :1 and Employees.DEPARTMENT_ID = :2
----- LEVEL 1: DETAIL 0 -----
(java.sql.SQLException) ORA-01008: not all variables bound

You need to set values for the parameters in your query before you try to execute the query in the view object.
So you need to call the setBindVars method before the query.

Differences between servlet and backing bean

Could anyone please tell me whether everywhere that servlet can be used, backing bean and JSF can be used too? Are JSF and backing beans the new alternatives for JSP and servlets? please clarify the relations between these concepts for me.
Thanks
Laura

Thank you. You mean backing beans can do every thing that servlets can do? Yes.
JSF pages can work with servlets? Strictly speaking, every JSF page gets passed through the FacesServlet which does all the task. The lifecycle, creating the FacesContext, putting the request parameters in backing beans, rendering the response, etcetera.
what are the advantages of servlet and the advantages of backing beans? what's the disadvantages? In general, which one is better?In context of JSF, you should be using backing beans, not Servlets. There is nothing what a Servlet can offer you as an advantage in the JSF context. It is simply not an option/alternative. You can't even call a Servlet (directly) using a JSF h:form. You, however, can access backing beans in any JSP or Servlet outside the JSF context.
Just carefully read the JSF specification or buy a JSF book and the picture will be clear.
JSF spec: [http://jcp.org/aboutJava/communityprocess/final/jsr252/index.html].

Difference between a Managed Bean and Backing Bean

hi
i am new to JSF made my 1st appl today ...
couldnt clearly understand difference between a Managed Bean and Backing Bean , anybody know the difference?
Regards
dsdsf

These are two terms that means the same .... A backing bean is a normal web term, in JSF specifically it is termed as managed bean as this' backing bean' configurations in faces-config.xml are termed within 'managed-bean ' tags.
Cutting the long story short its a bean class . period :)

Hi,
to call the bean, use the EL in Java and reference #{backingBeanScope.mapBean.initMap} as a method expression. If you try and access the bean directly then chances are that the instance is not available. Using EL from Java always guarantees this

Action method of backing bean called multiple times instead of once.

Hi,
My backing bean has an action method called "saveEquipmentList" that's called when a "Save" button is clicked. The problem is, this method gets executed twice every time the button is clicked so data gets peristed twice, db triggers get executed twice, etc., it's really pretty annoying. I've put the bean method's code and the JSF command button below, notice that there's a check for FacesContext.getRenderResponse() that I put in for debugging, the code doesn't get executed at all if I leave the FacesContext.getRenderResponse() in, sure, you're saying "So what's you point", no point, just thought I'd explain why the check is in there.
Thanks,
Alex
public synchronized String saveEquipmentList() throws Exception {
// Order is very important.
if (FacesContext.getCurrentInstance().getRenderResponse()) {
System.out.println("GOT RENDER RESPONSE... XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
try {
loadEquipmentCodesMap(); // Loads map from equip_code_ids in the DB.
updateEquipCodesMap(); // Updates total for objcode/type to sum of equipment items for that objcode/type.
saveEquipmentCodes(); // Saves to equipment_codes table.
loadEquipmentCodesMap();
updateDataList();
savedataList();
updateTotals();
loadEquipmentList();
catch (Exception e) {
setErrMessage("Error saving equipment: " + e.getMessage());
return "success";
}else{
//facesContext.getCurrentInstance().renderResponse();
return "success";
                            <h:panelGroup id="pg54">
                              <h:commandButton id="save" disabled="#{(user.role == '2' and backing_equipmentScreen.viewOnly) or
                                                                                      (user.role == '1' and !backing_equipmentScreen.viewOnly)}"
                                               value="Save"
                                               action="#{backing_equipmentScreen.saveEquipmentList}"
                                               styleClass="input"/>
                            </h:panelGroup>

Here's the phase listener output before clicking the "Save" button (which calls the saveEquipmentList() action method), I pasted it all, from app started to breakpoint, couldn't get it all in due to the 30K char constraint:

Passing params to the AMImp method from backing bean

Hello. I am an ADF/Jdeveloper Noob and i have a requirement where I have created an AM method below and exposed it to my View Controller.
I am using Jdeveloper 11..1.1.4 to doe this.
//In AM
public boolean createSRTask(String sourceName, Number sourceRow)
//insert new row in the Entity Object.
EntityDefImpl SRTaskDef = MassSrImportEOImpl.getDefinitionObject();
MassSrImportEOImpl newSRTask = (MassSrImportEOImpl)SRTaskDef.createInstance2(getDBTransaction(), null);
newSRTask.setSourceName(sourceName);
newSRTask.setSourceRow(sourceRow);
return(true);
I have a text file i am reading and I get the parameters from processing that file when the user presses the upload button... I can loop thru the file contents etc. with no issues but i have yet
to figure out how to code the backing bean to call the AMImp method with the parameters I have read in.
Thank you in advance for any help.

In this case you should build a VO which is build on EO, add it to the data model of the application module. The you can either implement the service method in the VO or the application module. Let's assume you put it in the am (application module) like you already did. the method there would look like
//In AM
    public boolean createSRTask(String sourceName, Number sourceRow) {
        ViewObjectImpl massView = (ViewObjectImpl)findViewObject("MassSrImportView1");
        Row row = massView.createRow();
        row.setAttribute("Source", sourceName);
        row.setAttribute("SRCNR", sourceRow);
        massView.insertRow(row);
        return true;
    }Some note on this:
1. the rows are not inserted in the db as long as you don't commit the transaction
2. It look like your view does not have a PK. The framework works better if you have one
3. If you always return true, you can omit the return value totally
4. If you plan to insert multiple rows you should consider passing hte file to the am method and do a bulk insert in there as this would minimize round trips.
I strongly recommend the you read the http://docs.oracle.com/cd/E25054_01/web.1111/b31974/bcintro.htm to get more knowledge about the business layer.

Calling a method in backing bean whenever a page is loaded/reloaded

Hi,
What is the best way to call a certain method in a backing bean whenever the jsp page is reloaded?
I have a managed bean that provides the data for a form and the bean gets it's data from a SQL DB. I want the bean to reload the data from the DB when and only when the page is loaded or reloaded. (I.e. it should the call method loadData() )
What is the best way to do this?
/R

If the bean is request scoped, just call the logic in the init block or in the constructor, or even in the accessor.
If the bean is session scoped, call the logic in the accessor.
http://balusc.xs4all.nl/srv/dev-jep-dat.html might give some insights.

Firing a method of backing bean on Page Load

Hi all,
Can anyone tell me how a method of the backing bean can be fired when the corresponding jsf page loads in the browser...
in fact some data is to be fetched from the server at the time of page load and rendered in one of the fields ... kindly help me in this regard ...
thanks in advance,
Neeraj Upreti

You can use a constructor or initialization block of the bean for this or maybe even introduce lazy loading in the getters, all depending on the expensiveness of the actual logic.
If you're using JSF 1.2, you can also use the beforePhase attribute of the <f:view> to specify a method which is to be fired on beforePhase of the view. You can also add @PostConstruct annotations to the methods which are to be fired on construction of the bean.

Calling init method on backing bean when JSP loads

Hi All,
My problem seems simple, but I'm not having much luck finding a solution.
I have a JSF page that shows the details of an employee. So I have an employee.jsp with a backing bean EmployeeController which works fine.
The change I need to make is this: pass in an employeeId to the URL and let my controller read it.
I've tried the following in my faces-config.xml:
<managed-bean>
<managed-bean-name>exmployeeBean</managed-bean-name>
<managed-bean-class>
    com.acme.EmployeeController
</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
    <property-name>employeeId</property-name>
    <value>#{requestScope.employeeId}</value>
</managed-property>
</managed-bean>And the following in my backing bean:
public void setEmployeeId(String employeeId) {
logger.info("METHOD CALLED");
this.refreshValuesForEmployee(employeeId);
}But I'm not having any luck (ie - this method is not being called).

it's ok. i found out why it wasn't working.
my scope was set to "session", but had to be "request" so that i could use the params syntax.
thanks anyway.

TP4 / AF:REGION / What is the way to work with af:region and Backing Beans?

<af:outputText value="Hello World!"/>
</jsp:root>So, my problem is in Backing Bean class (RegionTest.java). I don't know how I can acquire 'DCTaskFlowBinding' instance value; well, I don't know if that is the way to acquire the value of TaskFlowRegionModel, and even I don't know if this is the way to set the value of RegionModel. I don't know all of this because there isn't documentation yet :P
Some oracle-java-guru can help me, please?

Hi,
your biggest problem is the use of internal classes that probably will change without further notice and lead to a broken application then
I don't think that the region model is supposed to work without ADF binding in this release. If you need a page region then the Trinidad region should be helpful (though it doesn't support you with navigation cases as the taskflow does)
I'l check internally if there is an option to do what you are trying to do. However, as mentioned, if you need to use internal classes then the answer probably is no.

Access AM method from backing bean - best practice

Hello,
I need to call an appModule method from a backing bean. What is better?
1. Resolve bindings.AMDataControl.dataProvider, get AM and invoke the method directly
or
2. Create method action in page definition, resolve OperationBinding from it's binding expression and execute the operationBinding
I don't need to have a button on the page for this method.

Good question Rado.
With a "flexible" framework like Oracle ADF, I also ask myself sometimes what would be the preferred approach to do things.
