GET Method on JSF

ADFBC/JSF (10.1.3.2)
What should I do on the Calling Page to genete a URL with paramaters like this:
http://localhost:8988/oramag/faces/ViewEmployee.jspx?id=7934
Say for example Employee id needs to be passed as a parameter when the user clicks on the "Edit" button on the Employees View Page.
Where should I add the code? (on the Edit button or on the pagedef or both).
Thanks.

Thanks Shay for the response.
That is the method I tried first.
Calling JSF Form - Based on Read-only view
Called JSF Form - Based on entity object (1 table - 1 column primary Key)
And it worked fine.
However when I changed the primary Key of the entity object to use type "DBSequence" (with a database trigger), it is not working right. The called JSF fetches the first record instead of the one that is selected.
If I change the type back to "Number" it works fine.
Please advice!
Thanks.

How to get the current JSF phase in backing bean?
Edited by: jimmy6 on Nov 27, 2007 7:27 AM

I am using phasetracker to trace it also.I want to know whether it is it render response phase. I know FacesContext.getCurrentInstance().getRenderResponse() work for normal jsf component but it will not work for qiupukit datatable. FacesContext.getCurrentInstance().getRenderResponse() will not return true in the following phase. Why?
[ INFO] 27-11-07 16:20:21 : BEFORE RENDER_RESPONSE(6) (http-80-Processor23)
I want the 'get' method of datatable being called in response phase to reduce the number of calling because i put the query in 'get' method there. Actually i still straggling with the best practice to code the datatable...

I'm having the exact same problem, and it's freaking me out!!! The setGridPanel method is always called but not the getGridPanel. This one is only called the first time the page is rendered, and when I change a drodpdownlist it never gets the gridPanel again! I'm using an HtmlPanelGrid. Anyone can help please?
Thanks in advance,

What is the best practice to handle JPA methods in JSF app?

I am building a JSF-JPA web app(No EJB).
I have several methods that has JPA QL inside.
Because I have to put those methods inside JSF beans to inject EntityManagerFactory (am I right about this?).
And I do want to separate those methods from regular JSF beans which are used by page authors.
And I may need to use them in different JSF managed beans.
My question here is that what is the best practice to handle that?
I. write a or a few separate JSF Beans and inject them into regular Beans?
II. write a or a few separate JSF Beans and access them into regular Beans using FacesContext?
III. others?
Waiting to hear from you opinions.

You can create named queries on your Entities themselves then just call entityMgr.createNamedQuery("nameOfQuery");
Normally, we put these named queries in the class of the entity which will be returned. This allows for all information pertaining to a given entity and all ways of accessing that entity (except em.find() and stuff, of course) to be in one place. As long as the entity is defined in your persistence.xml file, any named queries which reside on that entity will be available through the EntityManager.
As for the EntityManagerFactory, we normally create an application scope bean which holds the factory itself (because this is a heavy-weight object) and then just get all EntityManager instances from that by injecting this bean into whatever needs it. For example, I might have:
//emfBB is the injected app scope bean which holds the entity manager factory.
private EmfBB emfBB;
private void lookupSomeData()
EntityManager em = this.getEmfBB().getEmf()
I hope this answered your question?

Whoa there, jumping to conclusions calling this a problem right from the start.
Yes its expected behavior. The getter can get called from several JSF lifecycle phases. I suggest you study what they are, otherwise you'll run into plenty more of these head scratching moments.

Why a getter method of a managed bean WILL be called multiple times

Why a getter method of a managed bean WILL be called multiple times during the JSF lifecycle?Why this designed?

This is by design indeed. Each step in the JSF lifecycle can call a getter to get the required information.

Getter method being called twice

Hi All,
I have a h:inputText which updates a h:dataTable as soon as the user types something into it (through the use of Ajax4JSF's a4j:support element). In this way I have something similar to a suggestionbox, but which modifies the table underneath rather than displaying a dropdownlist with possible values. My problem is that for some reason the getter method in the managed request-scoped bean to which the h:dataTable is bound, is being called twice everytime a letter is typed into the h:inputText. The first call seems to happen directly after the bean has been constructed, as the value to which the h:inputText is bound is still empty, and the second call after that, but with the correct value obtained from the h:inputText.
I searched the forums and found posts detailing similar problems, but I couldn't find an explanation of why it happens or a way to get rid of it. The common consensus seems to be to not have any processing intensive operations in the getter and to just accept that it will be called twice.
Is there really no way around this?
Thank you,
Ristretto

This is just the default behaviour of the JSF lifecycle. The first call checks if there is a default value or a value which is been set in the previous request. The second call gets the newly set value for display which is been set during the request processing. A way to get rid of the first call might be writing your own lifecycle implementation.

Oracle.jbo.AttrValException: JBO-27019: Get method for attribute

Hi Guys,
I am trying to add a new column to Oracle quoting.It has already been customized by some consultant few years back. I followed the note 392728.1 on metalink and also have the documentation by the previous consultant but getting the error oracle.jbo.AttrValException: JBO-27019: Get method for attribute Draft in HeaderVO could not be resolved after adding my column, when I try to print the quote.
Here are the steps I took
1) added a column to the query (at the end) in HeaderVO.xml
2) added the below code in the HeaderVO.xml
<ViewAttribute
Name="DRAFT"
IsQueriable="false"
IsPersistent="false"
Precision="100"
Type="java.lang.String"
AliasName="DRAFT"
ColumnType="VARCHAR2"
Expression="DRAFT"
SQLType="VARCHAR" >
<DesignTime>
<Attr Name="_DisplaySize" Value="100" />
</DesignTime>
</ViewAttribute>
3). Modify HeaderVORowImpl.java file to add setters and getters for the newly added view attribute. For example,
a) case 67: //
setDRAFT((String)obj);
return;
b) case 67:
return getDRAFT();
c) ublic void setDRAFT(String s)
setAttributeInternal(67, s);
public String getDRAFT()
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
Everything is dont exactly as per the manual but not sure why I am getting this issue. Any help will be appreciated.

a) case 67: //
setDraft((String)obj);
return;
b) case 67:
return getDraft();
c)public void setDraft(String s){
setAttributeInternal(67, s);
public String getDraft(){
return (String)getAttributeInternal(67);
d) protected static final int DRAFT = 67;
can u change it as explained above.. setDRAFT should be setDraft.. and getDRAFT should be getDraft..
and make sure that the index.. number is exactly matching with the attribute order in the VO

Can't get my class's getter method to work properly.

Hello, I am new to Java programming, although I come from C and C++. This is my first post. I am working on a basic Library application that can Checkout and Return books. Eventually I would like to add the ability to read from and write to an XML file containing data for every book.
My problem right now is that I cannot get my getter method within my Book class to work properly. When I call getData() from within main, and pass the appropriate arguments, instead of filling the variables with that object's data, it leaves them blank! Please help me.
Here is my method within the Book class, the person and id_num are private.
/* Gets general Book Instance Data and fills parameters with it */
     public void getData(String n, int num, String c, String d)
          n = this.person;
          num = this.id_num;
          c = this.checkout_date_string;
          d = this.due_date_string;
     }Here is how I am attempting to use it in main:
String name = "";
int number = 0;
String checkout = "";
String due = "";
Book book1;
/*Sets person = John Smith and id_num = 10763*/
book1 = new Book("John Smith", 10763);
/*Gets Checkout (todays) date and sets a due date in 2 weeks*/
book1.Checkout();
book1.getData(name, number, checkout, due);
System.out.println("Book1:\n Checkout Date: " + checkout +
                         "\n Due Date: " + due + "\n Is it late: " + book1.isLate() +
                         "\n Person who checked it out: " + name + "\n ID number: " + number +
                         "\n ");Then, Here is the Output:
Book1:
Checkout Date:
Due Date:
Is it late: false
Person who checked it out:
ID number: 0

Well I went ahead and made separate methods to return each value. I suppose that will work just as well, especially since now I don't have to declare a bunch of strings and int's to hold the data and pass to the method.
>
Well this would never work anyway
public void getData(String n, int num, String c, String d)None of those can be changed within the method. Strings are immutable and 'int' is passed by value. Each of those parameters will have the same value after the method exits as they did before it was called.
Your book class should be using 'setters' to set the value of its instance variables.

How can I implement a get method that lets me divide two values, Help plz

I need to implement a method that divides the values return by two other methods but I keep getting an error message, I think its divide by zero error ( I am not too sure on the exact error msg as I do not have java installed on this pc as yet), here is my example,
I have two get methods that take an int value so say
getValueOne() as method one
getValueTwo() as method two
Now I have a third method that does the following,
Public int getValueThree() {
int value =0;
value = (getValueOne() / getValueTwo())
return value;
I am not two sure on the exact code but it does something like this and I get an error. Could someone please guide me how I can successfully implement a get method that divides two values that are returned by two methods.
Thanks,
Zub

Hi, thanks for your reply. Right, how can I go about to throw an exception? I can definitely give the exact code and error message tomorrow when I can access my home pc.
And you are right there are some values that are zero! I am not very sure what throwing an exception means to be honest. Could you please give an example?
Thanks...

No Getter Method Error

I had a working JSP/Struts application. I added a new data page and struts forward, and started getting:
No getter method for property Fullname6 of bean org.apache.struts.taglib.html.BEAN
errors.
I have confirmed that the Fullname6 is referenced in the UIModel.xml file. My changes were only to add a read-only table to the jsp that is failing, so I don't see how that could be causing this error. I made no changes to the struts action that forwards to this page.
What is going on here? Anybody have any ideas?

I know about the link that you've sent.
We don't have a specific form bean for this, as we have 'DataForm' which takes care of get/setter method for the attributes. I am using ADF, JSP, Struts and parameterized where clause in my VO. I do not know how to procede as it doesn't allow me to create the form bean.
Thanks,

Null pointer exception in getter method

I am trying to have a getter method that returns a collection. The method is supposed to get a list of files from a directory and returns the collection. I am instantiating the List in the method and the converting an array into the List using asList. Then I am trying to return the list to the main method.
When I put this code in the main method I get the result I want, but when I try to put it in the getter method and call it from main I get a NullPointerException compile error.
I need help understanding what I am doing wrong when I move this code out of the main method and into another non static method.

I was looking around at other posts and noticed they
give more code than I was. I was trying to save you
some reading but now I see I just made it harder.No problem. It can be difficult to know just how much code to post to get all the relevant stuff but not a bunch of extraneous junk.
The problem is you have two different currentDirectory variables. The member variable (declared just inside public class FileBrowser and a method (or "local") variable declared in main. The local one in main hides or shadows (those two terms are similar in Java, and I forget the details of which is which) the member variable.
When you set the one in main, it doesn't affect the member variable. The local one in main only exists inside of main.
To fix this, change this line inside of main: File currentDirectory = new File(System.getProperty("user.dir")); to this: currentDirectory = new File(System.getProperty("user.dir")); By having the class name File there you're declaring a new variable. Without the class name, you're just using the existing member variable.
