Get properties value from a bean

Hello
I just began with JSF and have a problem. I konw how to save and get properties value into/from a bean from/into a jsf page. But how can I get the values from a other java class? I would like to get the properties from the bean A and use them in the class B and write them at the end back into the bean. What would be the easiest way for this?
Thank you for the help!
Best regards, mike

Depending on the scope of your bean (request/session), have a look to the related method (getSessionMap or getRequestMap ) from ExternalContext class (accesible from FacesContext.getCurrentInstance)

In the new Java Class How can I capture the Event When I click the Buttong the InputField value capturing into the AbstractPortalcomponent Class.
I tried like this but It comes as Null Value.
Event event = myContext.getCurrentEvent();
                          if(event!=null)
                              InputField ip= (InputField) myContext.getComponentForId("spoofCust");
                              String spoofCust=ip.getValue().toString();
Please suggest me in this.

Lohitha,
Try replacing your two lines of code:
InputField ip= (InputField) myContext.getComponentForId("spoofCust");
String spoofCust=ip.getValue().toString();
with:
InputField ip = (InputField) getComponentByName("spoofCust");
String spoofCust = ip.getValueAsDataType().toString();
Let me know how that works for you.

Re:How to get the vo from managed bean

Hi all,

Thanks,

So you're not using ADF BC at all, right ?
From JSF point of view, it does not matter how you provide UI control values.
What you can do, for example, is to use pure JDBC in order to get and display the database values.
What you need in your backing bean, is appropriate properties (setter/getter method pairs).
In the getter, you can obtain DB values by using JDBC
Take a look at:
JSF 2.0 + JDBC integration example

Can we Return values from Java Bean to Form

Hi All,
I have a Bean area defined on a Form. The Bean Area consists of a Text field which gets populated by path of a file selected using Browse button.
Can I return this path as a parameter from the Java Bean to the form? Is there any function for this?
Regards,
Prathima.

If you designed your bean to offer the ability to exact info/data from it, then yes you can get a value from the bean into the form (pl/sql) - using Get_Custom_Property
Refer to the following which is a good example of how to build a bean. Specifically look at page 12 where is shows how to use Get_Custom_Property.
This is NOT an Oracle supported or provided document or web site, but it is a very good example.

Htmlb:get the values from bean n display it in textView

Hi,
I am doing one PDK application using jspdyn page. In jsp page I am using htmlb to display the table. In that I am using one text view element. There I need to get the values from bean class.And display it in a table.
Can anyone help me how can use the textView inside htmlb to retrieve the values from bean.
Thanks & Regards
Vineela

hi vineela,
For the textView, in the text value write the code <%=myBean.getStr()%>
where myBean will be your bean class and getStr() is the method in the bean class whcih returns value which needs to be displayed on the screen.
Thanks

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

NullPointerException - Cannot get the value from variable f_cashGiven

In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!
Enclosed please find the source code of SubCheckout.java and VNumber.java

If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.

How to get selected value from selectOneRadio ???

Hi...i want to how to get selected value from selectOneRadio and use it in another page and in backing bean.
Note i have about 10 selectOneRadio group in one page i want to know value of each one of them.
Plzzzzzzzz i need help

You have a datatable in which each row is a question, correct?
Also in each row you have 5 possible answers that are in a radio, correct?
So,
You need to put in your datatable model, a question, and a list of answers (5 in yor case) and the selected one.
So you will have a get to the question, an SelectItem[] list to populate the radios and another get/set to the selected question.
ex:
<h:selectOneRadio value="#{notas.selectedString}" id="rb">
<f:selectItem itemValue="#{notas.valuesList}"/>
</h:selectOneRadio>
Search the web for examples like yours.

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

How to get selected value from SelectOneChoice

Hi,
I'm facing a problem to get selected value from SelectOneChoice. I have valueChangeListener event on a (SelectOneChoice)item. After user makes a choice I want to store selected value in a bean property to pass it to a method.
For example List item shows dname from dept table after user makes a choice I want to get deptno and populate into bean which I use to pass into my method.
If I use valueChangeEvent.getNewValue() I always get negative value instead I want deptno selected. Sample code pasted below.
public void setDeptno(ValueChangeEvent valueChangeEvent) {
BindingContainer b = getBindings();
OperationBinding oB = b.getOperationBinding("setDeptno");
//Checking instance of because same method is called from another text inputText item.
if (valueChangeEvent.getSource() instanceof CoreSelectOneChoice){
CoreSelectOneChoice cN = (CoreSelectOneChoice)valueChangeEvent.getSource();
if (columnName.getId().toString().equals("deptDname")){
JSFUtils.setManagedBeanValue("dept.deptDeptno",valueChangeEvent.getNewValue());
}

if your selectOneChoice has value equal to #{bindings.deptno} bound to the iterator Dept1Iterator,
then the backing code will look more like
                public void setDeptno(ValueChangeEvent valueChangeEvent) {
                    BindingContainer b = getBindings();
                    OperationBinding oB = b.getOperationBinding("setDeptno");
                    //Checking instance of because same method is called from another text inputText item.
                    if (valueChangeEvent.getSource() instanceof CoreSelectOneChoice){
                        CoreSelectOneChoice cN = (CoreSelectOneChoice)valueChangeEvent.getSource();
                    if (columnName.getId().toString().equals("deptDname")){
                        FacesContext ctx = FacesContext.getCurrentInstance();
                        Application app = ctx.getApplication();
                        ValueBinding bind = app.createValueBinding("#{bindings.Dept1Iterator.currentRow}");
                        Row row = (Row)bind.getValue(ctx);
                        JSFUtils.setManagedBeanValue("dept.deptDeptno", row.getAttribute("deptno"));
                } I haven't tested it, so it could perfectly not work at all

How to get the value from the checkbox

Hi All,
Good Evening,
i want to get the value from the check box.
for this i wrote like this
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String val=cbb.getvalue(pageContext).toString();
val getting the value only when checkbox is checked.
suppose check box is not checked that time i got NULL POINTER exceptionn.
so
i tried the following way alsoo
string val=pageContext.getParameter("item240");
here val return 'on' only when checkbox is checked.
otherwise NULL value returnss.
but i want to get the value is 'Y' when i am checked the checkbox
otherwise returns NULL valuee.
already i set the checkbox properties alsoo
Checked :Y
unchecked:N
pls tell me

Hi,
use
try
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String test = cbb.getvalue(pageContext).toString();
catch(Exception e)
String test = "";
this way you can handle null pointer exception.
Thanks,
Gaurav

Get/Set values from a drop down list

I am trying to modify the http://www.netbeans.org/kb/60/web/web-jpa-part2.html so that instead of entering the data from a text field (in update & add) the values come from a drop down list from a table. I have drop down lists that are populated bothe from the DB and hard coding. When I run, I am able to see the options on the DDs. But none of the CRUD work. I think this is because my set and get for the drop down is wrong. Then again, I also have a few text fields from the original example which also don't seem to work. Here is a piece of my addButton():
        RowKey[] selectedRowKeys = getTableRowGroup1().getSelectedRowKeys();
        PaymentDetails[] pv = getSessionBean1().getPaymentVoucher();

        addRequest = false;
        return null;How do I set and get the values from the drop down so than it passed to my bean? When I choose a row to be updated, make changes and click Update, I get this message on my Tomcat:
com.sun.webui.jsf.component.DropDown::The current value of component form1:deptCodeDD does not match any of the selections.
Did you forget to reset the value after changing the options?Can someone please point me to a place which shows how I can add a default value from my DD? I tried to follow http://www.netbeans.org/kb/55/dropdowncomp.html, but unable to complete because I get an error for Options api. The auto-fix imported import org.apache.jasper.Options; But the package given in the tutorial is com.sun.webui.jsf.model.Option. My Java version is 1.6.0_07.
private Options listOptions[];
...//getter setter goes here
listOptions = new Option[noofDBRows + 1];Many Thanks!

I don't guess what I may add.
The contents of the table named lookup appear on the screenshot.
cell A1 contains the string One-Piece, cell B1 contains the 'associated' value 160.
cell A2 contains the string Two-Piece, cell B2 contains the 'associated' value 130.
cell A3 contains the string Three-Quarter, cell B3 contains the 'associated' value 150.
Now table Main
In column B the cells contain a pop_up menu with four items like the ones described by Jerrold.
In column C of the cells contain the formula :
=IFERROR(VLOOKUP(B,Tableau 2 :: A:B,2,FALSE),"")
I enhanced it since yesterdays because I forgot to treat the case when cell is blank in column B.
I apologize but as I'm using my machine in French, the screenshot display the French formulas.
I repeat that you may find useful infos in the PDFs files which we may download from the menus:
Help > Numbers User Guide
Help > iWork Formulas and Functions User Guide
As you are in Stoke-on-Trent maybe your system is set to use the comma as decimal separator.
If it's that, you must replace the comma by semi-colons in the formulas (you may see them in my screenshot).

RE: Getting multiple values from more than one multiple select popup window

I have a button on a JSP of mine that when clicked creates a popup window (right now it is called popup.html) with a multiple select menu.
My question is how do I get all the values selected from the menu into my JSP (sample.jsp) so that I can set each of the values for my bean.
The other problem is that I have more than one select multiple menu.
Please help if you can. Any advice or suggestions here would be greatly appreciated!
Thank you!

I realize that I can use request.getParameterValues to get the values selected from my html because I am passing them to the hidden inputs I have and then using the request.getParameterValues to get each of the values.
MY PROBLEM IS WHAT IF I HAVE 4 MULTIPLE SELECTS??? How can I use the same html popup menu to get the values from the 4 different multiple selects????
I look forward to your response.
This code is from my JSP:
<INPUT TYPE="TEXT" NAME="Field1" SIZE="15">
<INPUT TYPE="hidden" name="F1Rad1">
<INPUT TYPE="hidden" name="Permission">
<input type=button name=choice onClick="window.open('optionPicker.html','popuppage','width=250,height=100');" value="Options"></TD>
Here is my optionPicker.html code for the pop up menu:
<html>
<head>
<script language="JavaScript">
function sendValue(s)
var boxSize= s.options[0].value;
var restrict = s.options[1].value;
window.opener.document.addNewForm.F1Rad1.value = boxSize;
window.opener.document.addNewForm.Permission.value = restrict;
window.close();
</script>
</head>
<body>
<center>
<form name=selectform>
<select multiple name=selectmenu size="2">
<option value="large">Large Text Input Area
<option value="restrict">Restricted Access
</select>
<p></p>
<input type=button value="Select Option(s) For Field" onClick="sendValue(this.form.selectmenu);">
</form>
</center>
</body>
</html>

I can not get link-value from af:tree.

Hello.
I use jdeveloper 10g.
I can not get link-value from tree.
I use following code:
<f:facet name="nodeStamp">
<h:panelGroup binding="#{backing_dialogDic_dic_ETS.panelGroup1}"
id="panelGroup1">
<h:outputText value="#{item.vidNum} #{item.vidName}"
binding="#{backing_dialogDic_dic_ETS.outputText1}"
id="outputText1"/>
<af:commandLink
binding="#{backing_dialogDic_dic_ETS.commandLink2}"
id="commandLink2"
action="#{backing_dialogDic_dic_ETS.returnObject}">
<af:setActionListener from="#{item.idVid}"
to="#{processScope.ETSId}"/>
<af:objectImage source="/images/icons/10.gif"
shortDesc="Выбрать"
binding="#{backing_dialogDic_dic_ETS.objectImage2}"
id="objectImage2"/>
</af:commandLink>
</h:panelGroup>
</f:facet>
</af:tree>
//in java bean:
public String return_Object() {
Object ob = JSFUtils.getManagedBeanValue("processScope.ETSId");
System.out.println(o);
return null;
In console I see null.
How I get this value???
I can get this value if i use treeTable instead of tree.
Thx, Dema.

Hi,
not that I think it matters, but the processScope is not a managed bean but a memory scope. So if
JSFUtils.getManagedBeanValue("processScope.ETSId");
assumes a managed bean then this may be incorrect as most likely there exist no managed bean with this name. You should be able to access the process scope from AdfFacesContext.getProcessScope(), which then returns a Map, which you call get("ETSId") on
