Getting the value of variable in a bean

hi
I have method in my class and I'm passing some values in it.
example:
public static boolean authenticate( String name, String passwd)
//declare my variable
boolean authorized = false;
//do processing and set my variable
if(name.equals("") || passwd.equals(""))
return false;
// if name and passwd exists set authorized to true
authorized = true;
return authorized;
Question:
How can I get the value of authorized in my webpage using jsp?
or
How can I get the value of authenticate in mywebpage using jsp?
please help !!!!
thanks in advance.

Here's how I did it:
This snippet is from my StringTable Bean
public static final String SERVER_ERROR = "Server has returned an error.";
public static final String DATA_ERROR = "Data could not be retrieved.";This is how I access it in a JSP
<jsp:useBean id="Strings" scope="session" class="com.cognitronics.utilities.StringTable" />
<% if ( strResult.equals(Strings.SERVER_ERROR) ) { blah blah blah... }Hope that helps a little.

Hi
Use the link below and download the documentation
http://www.oracle.com/technology/documentation/bi_ee.html
I think you will find what you are looking for in the Answers, Delivers, and Interactive Dashboards User Guide, but in short the syntax to display a variable value is as follows:
As shown above the syntax for using a presentation variable is:
@{variablename}{defaultvalue}
For Session variables use:
@{biServer.variables['NQ_SESSION.variablename']}
For repository variables use:
@{biServer.variables['variablename']}

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.

Getting the value of variable indirectly

Hi all,
I want to get a value of variable which is contained in another variable
for example :-
data lc_table1 type string value 'ZTABLE'.
     CONCATENATE 'lc_table' '1' INTO lv_tablename.
     lv_estructura ?= cl_abap_typedescr=>describe_by_name( lv_tablename ).
      lt_ls_components = lv_estructura->components.
In the above value of lv_tablename = lc_table1.
i want to get a value of lc_table1 , that is ZTABLE ,,can any one please help me to get this
thanks
Avinash DM

Hi Avinash,
If I have understood your requirement correctly, you need to pass the value of lc_table1 to cl_abap_typedescr=>describe_by_name.
You can do it like this:
data lc_table1 type string value 'ZTABLE'.
FIELD-SYMBOLS: <fs> TYPE any.
CONCATENATE 'lc_table' '1' INTO lv_tablename.
ASSIGN (lv_tablename) to <fs>.
r_descr ?= cl_abap_typedescr=>describe_by_name( <fs> )
Please let me know if this helps.
Thanks & Regards,
Surmeet

Getting the value of variable dynamically

Hi Gurus,
How can i get a value of a variable dynamically through user input?Is it possible to get it interacively?
my reqiurement is to control my loop according to the user supplied value for the flag variable.
if the user gives the flag as 'Y' loop should continue.else loop should terminate in a PL/SQL block
here is a piece of code
CREATE OR REPLACE procedure c is
flag1 varchar2(10):='Y';
begin
while flag1 <> 'N' loop
dbms_output.put_line('Enter the value.....' );
+*<< Here I have to get the value of flag1 from user .How to get the user value>>*+
end loop;
end;
Please advice

To add my 2 cents worth you can not get where you want with sqlplus calling PL/SQL
You have 2 problems
SQLPLUS has no loop construct and not much in the way of conditional capabilities.
PL/SQL can not talk to a terminal.
If you use an &variable in an anonymous block, it is evaluated by sqlplus before the parse of the block takes place.
Nothing you do in the block can change its value.
dbms_output.put_line buffers everything output to it and then sqlplus outputs it all after the block completes.
You can accept variables in sqlplus and pass them into an anonymous block for use, but you would have to exit the block if you wanted to ask something based on a condition determined in the block. You would then have no way to re-enter that block within the sqlplus session.
Host language programs do not have this problem. You can use ProC ProCOBOL, OCI, Visual Basic, and web interfaces.
Unless you are on windows you can use a shell script (Unix, Linux or VMS) to do what you want.
You can accept the variable in the script within a loop. You can call sqlplus silently passing the variable on the command line. You can use the variable command to define variables that will be set in pl/sql blocks use selects of these :variables to set defined sqlplus &variables. You can spool files that will then be processed by the shell language. All this can be done in that shell loop.
In other words you can do anything you need. You do need to understand your tools and their limitations. You can not use sqlplus commands in pl/sql for 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

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

How to get the value of a variable defined in javascript in JSP

how to get the value of a variable defined in javascript in/through JSP????

In Javascript you can use the DOM to access the input element and set it's value before submitting the form. Then it's value will just be passed.

How to get the value of a variable in group footer in the report footer also

I have a placed a formula as below at the group footer and the report footer. The data is grouped on the basis of duedays which is again formula and the value in that is appearing correctly.
Whilereadingrecords;
Global Numbervar CNTONE;
Numbervar P := P+1;
IF P = 1 AND {@DUEDAYS} = 0
THEN CNTONE := {spSUPPLIERSOA;1.INVOICEBAL}
ELSE IF P>1 AND {@DUEDAYS} = 0
THEN CNTONE := CNTONE + {spSUPPLIERSOA;1.INVOICEBAL}
At the group footer I get the value correctly for CNTONE but when I place the formula in Report footer I get the value for CNTONE as 0.
Please do let me know how I could get the same value in the report footer also.
Regards
Sreejith J

Hi Abhilash;
When I give the statement whileprintingrecords then my above formula sums up only the first record and the last record of the group and when I give whilereadingrecords it adds up all the data in the group correctly.
The formula that you mentioned for the report footer had worked out and it is showing my result correctly.
I did not put up the reset formula on the group footer because as the group changes I had used another variable in another formula for example for the second group I used
Whilereadingrecords;
Global Numbervar CNTTWO;
Numbervar Q := Q+1;
IF Q = 1 AND {@DUEDAYS} = 30
THEN CNTTWO := {spSUPPLIERSOA;1.INVOICEBAL}
ELSE IF Q>1 AND {@DUEDAYS} = 30
THEN CNTTWO := CNTTWO + {spSUPPLIERSOA;1.INVOICEBAL}
I have set up total 5 such formulas as the number of groups that will be formed is 5. I have put up these formulas on the group footer and suppressed it as I dont want to get it displayed.
The as you suggested the solution for Report Footer I did that and getting the result correctly.
I dont know I may be following a longer procedure
Take Care

How to get the value of a variable in FOX?

Hi,
In the FOX program how to get the value of a variable defined in planning area?
can anyone give me some sample code?
thanks

Adding to the last reply,
you can use VARI(variable) to get the count of the values.
In the latest version of BPS, you may also use the following new foreach construct:
FOREACH var IN VARIABLE variable_id.

<h:inputText id="test" binding="#{Bean.editableInputText}"></h:inputText>
When I load the page I can see the TextField with the value that I set previously (in the backin bean).
The problem is when I try to change the value of the texField:
I change the value, then I click on a button (its action is to call a method to get the value of the field).
In debug mode I see that the value is allways the first set instead of the new value inserted.
I tried with getValue and similar but it does not work.
I tried also to put HtmlInputText in a panel (using a similar logic) and then to get it using getChildren() method but also this does not work.
Any idea?
Thanks in advance

Ok (now I understand)
I have used bean.getEditedInputText() and it is not null.(I got the HtmlInputTextObject)
But bean.getEditedInputText().getValue has allways the first value set.
If I don't set previously the value (in the backin bean) the getValue() is allways null.
So my problem is that I can set but I cannot get the Value when I change it.

Variable type Hierarchy, how to get the value from another similar variable

Hi.
We have created a variable, type hierarchy (using ORGEH hierarchy in HR based on 0ORGUNIT). Let's call this VAR1. We want to fill this with an User Exit, beacuse we want VAR1 to have the value from another variable, VAR2, which is also type hierarchy (and based on the same characteristic).
However, when we program this user exit and use the VAR1 afterwards, it just behaves as if we have a single characteristic value and not a node value. As a result, we just get posts which do have the 'parent itself' as characteristic value, and none of the subnodes... Any hints as to what we can do in our User exit to get the value passed over from VAR2 to VAR1 as a node value? Is there any spesific syntax to be used here that we are missing? ( The VAR1 and VAR2 are both defined as hierarchy variables, we have double checked...).

Hi,
are you on BI7.0? There you can create variables type replacement path and get the value out from a different variable without any coding.

How Can I get the value of a variable name stored in another variable?

I have a scenario wherein i get a record as %rowtype as input parameter into my function and i generate a dynamic sql to check the validity of a particular value in one of the columns of the input parameter record.
I have a variable that stores the column name of input parameter record whose value is to be validated.
The dynamic SQL looks like this:
'Select empno from emp where empname = input_rec.'||v_colname
While using Execute Immediate I get the error - Invalid Identifiier -'input_rec'.'ename'
On Googling I found that the input parameter is out of the scope of the SQL that's being executed in the Execute Immediate.
Is there any way I can get the value of ('input_rec.'||v_colname) so that I can pass it into the Execute Immediate with 'Using' clause?

Best way to get the values of local variables

What is currently the best way to get the values of local variables. I know it is not currently possible to set watchpoints on local variables, but what are the best workarounds?

You have to use StackFrame methods, eg, visibleVariables and getValues. To get a StackFrame for a thread, that thread has to be suspended, eg, by a BreakpointEvent.

Can't get the value of publicdelegatesbl in a variable

Hello,
When a mailbox is disabled if the user was as a delegate in another mailbox and that the user didn't remove him from his delegate, he'll see a unknown SID in his delegate. In order to prevent this I would like to run a script that will remove delegatebl
of that the user who would be disabled.
Servers are on Exchange 2007 SP3 RU6. No powershell V2 is installed... only V1. That's my main problem. I have the Quest cmdlet installed. I can only used them.
I wrote a script but my problem right now is only to get the value publicdelegatebl in a variable... I have a blank return...
$QADUser = (Get-QADUser "$User" -IncludedProperties publicdelegates,publicdelegatesbl).publicDelegatesbl
Write-Host $QADUser
Any help please?

Thanks it worked... but now when I am trying to remove the publicdelegatesbl I have a constraint violation error. I understand what you've told me about the fact we cannot clean up the message without using outlook. But is there any other solution except
Outlook? I meant even with the EWS it's not possible?
Currently I have to be able to remove the delegate added by outlook and by scritpt...
$resFile="C:\Scripts\leavers.txt"
$allLeavers = Get-Content $resFile

$valeurs = $leaver.split(";")
$aliasTH = $valeurs[0]
$smtpTH = $valeurs[1]
$User = Get-Mailbox | Where-Object { $_.Alias -match $aliasTH -and $_.EmailAddresses.ToStringArray() -match $smtpTH }
$userCN = $User.DistinguishedName
$Error.Clear()
$userPath = "LDAP://$userCN"
$user=[adsi]$userPath
$publicDelegates = $user.properties.publicDelegates
$publicDelegatesbl = $user.properties.publicDelegatesbl
Write-Host "$publicDelegates,$publicDelegatesbl"
$publicDelegatesbl.Remove("$userCN")
