How to call User Define Function

Hi,
I need a help....
In my Project I have Login.jspx page in which there is a textbox Username.
I have second success.jspx page which has its success.java bean class in which i have define a method "display()".Now i want to cal display() in my success.jspx page.
can anyone help me out what is the way to do this.
Thanks in advance...
Thanks,
Nehal

Hi Abhijit,
Sure i can give you more details on the same:
I have written a displayVal method in ForgotPassword.java bean class
public String displayVal() {    
String txtVal = AdfFacesContext.getCurrentInstance().getPageFlowScope().get("testValue").toString();
nameID.setValue(txtVal);
return txtVal;
Now in ForgotPassword.jspx page i have one input text box named "nameID" in which i want to display some value from the user-define method called displayVal()
now i am trying to call my user-define method in my ForgotPassword.jspx page:
<af:inputText label="Name"
binding="#{backingBeanScope.backing_FrgtPwd.nameID}"
id="nameID"
value="#{backingBeanScope.backing_FrgtPwd.displayVal}">
</af:inputText>
but is is showing an error that: backingBeanScope.backing_FrgtPwd.displayVal is not a property as this a method.
So now my query is : Is there any way by which i can call my user-define method on the jspx page from the bean class of the same page.

  • How to call User defined functions in Mathscript Node ?

    Hi,
    I have created a user defined function and saved it to Search path of Labview as an M file. If I run my program in Math script window, the function is recognized and the program works properly. If I do the same with MathScript node , the user defined functions are not identified.
    Kindly help me with this problem. Thanks in advance

  • Matscript node void ouputs when calling user-defined functions

    Hi,
    I have a (for most of you, probably simple) problem with calling user defined function within a mathscript node.
    I have a script inside a MathScript node which calls three UD functions. When I try to output variables, LabView sets their type to void, so I cannot use them further. this would imply, that the script is nondeterministic, (since the types would get set at runtime). However, if I replace the call to the UD function with the actual contents of the function, the variable becomes deterministic. Now, since I have several call to these functions, I have no desire in writing all of them many time, introducing many variables etc. What would you advise me to do?
    Find attached my scripts and functions.
    I need this script running on a RT Target, and have been battling this for weeks, with almost no success!
    Thanks, Regards,
    Luka

    MArtin, hello!
    As far as I know, LabView checks the syntax as you write in the MS Node, and since there is no X mark next to the line number, it indicates, that the syntax is correct. Since i have set the path to the UDF in both the VI options and in the general MAthScript setting, how does adding the path command help? even if I add path('directory') command, a yellow exclamation mark appears, saying the command is slowing down performance.
    (this is the original help explanation:
    The warning glyph indicates that LabVIEW operates with reduced error checking at edit time and slower run-time performance for the MathScript Node. The following conditions cause the warning glyph to appear. To remove the warning glyph from the MathScript Node and improve run-time performance, modify your script as follows to resolve the condition in your script:
    Your script calls addpath or pathremove (legacy name rmpath), or calls cd, path, or userpath with one or more inputs, which change the MathScript search path list at run time. Remove these functions and use the MathScript page to configure the default search path)
     Could you please post a screenshot of your VI, just to see, if you've got anything different set up?
    I am running LV2012.

  • Calling user defined functions through OBIEE

    Can anyone tell me how I can call the user defined functions on database through the new BI tool.
    The idea is to collect certain parameters through the prompt when launching the request, the function is supposed to pick up the parameters, make a certain calculation, and return a value.
    I wrote the function, I just need help over how to call the function through the BI tool - that was pretty easy in the old Discoverer.
    Thanks.

    Hi Kresimir ,
    You can use EVALUATE function to call a user defined function.
    EVALUATE('FUNCTIONNAME(%1,..)' As DATATYPE,parameter1,...)
    Here DATATYPE is the returntype of function.
    Hope this will help.
    Thanks

  • Calling user defined function in Oracle BI Answers?

    Hi
    I am new in Oracle BI . I want to use the user defined function in Oracle BI Answers as a column,function written in Oracle database to calculate the Sales Revenue.
    I am using Oracle BI Standard Edition One and Oracle 10g database.
    Please suggest me.

    Search for EVALUATE function you can call function and pass parameters
    Example:
    EVALUATE Function
    This function is intended for scalar and analytic
    calculations.
    Syntax: EVALUATE('DB_Function(%1)', {
    Comma separated Expression})
    Example: SELECT

  • How to migrate User Define Function to another mapping in other namespace

    Hi Everybody
    I have define many User Define Functions in mapping
    How can i use them in other mapping
    Thank you in advance

    Hi,
    I tried to explain the steps.
    1. Take the JAVA code of your User-Defined Functions
    2. Go to a JAVA editor (e.g NWDS, Eclipse, etc...)
    2.1. create a Java project
    2.2. create a Java class
    2.3. inside your Java class, put each JAVA code of your User-Defined Function inside a Method
    2.4. Export your Java class to a JAR file (e.g my_tools.jar)
    3. Go to IR
    3.1 create an Imported Archive (IA) and upload your JAR file.
    3.2 in this IA, you see your Java class which contains all your methods.
    4. inside your mapping,
    4.1 create a User-Defined Function <u>and import</u> your class
    4.2 use your method.
    So, you define in only one place your code (thanks to a IA) and you will be able to use it inside several mappings.
    I hope I don't forget steps...
    Advantage: if tomorrow, you want to create a new function, just add a new method to your Java class and re-import your JAR file
    Oh, I missed: your IA must be created inside a specific Software Component (SC__TOOLS) and this one must be linked with the others by a "Usage dependency", else your IA will be recognise only in one Software Component (and maybe only in one namespace)

  • Calling user defined functions in Matlab Script Node

    Greetings!
    I am not successful in calling a user defined function inside a Matlab Script Node.
    The path has been added to Matlab, but the Matlab script node is not calling my function.
    I am calling it as follows:
    a= fcd(b,c);
    and the fcd.m file is calculating the 'first central difference' - works in Matlab, but not in LabVIEW:
    function MtxOut=fcd(MtxIn,dt)
    %MtxOut=fcd(MtxIn,dt)
    %first central difference method of finding instantaneous
    %first derivatives
    %MtxIn = MxN matrix of inputs
    %dt = time change between inputs
    %MtxOut = MxN matrix of first derivatives of inputs

    c=size(MtxIn,2);
    MtxOut(1,=(MtxIn(2,-MtxIn(1,)/dt;

    for i=2:r-1

  • How to call user define data type as data type for concurrent parameter

    Hi All,

    i.e.
    i have one of the parameter of table type i.e. user define data type at PLSql program
    now i need to register same PLSQL program into oracle applications as concurrent program
    but while i am creating Parameters for concurrent program
    How could i define that user define data type at database level in oracle applications using 'Value set' ?
    any one save me from this Problem
    thanks and Regards,

    Don't think this can be done..
    One way I can think of is to wrap your PL/SQL program under another procedure/package that can accept "normal" parameter,and use/register this wrapper instead of your original pl/sql program.

    Hi Sandeep,
    Please kindly refer to the definition of this type:
    You can use this type of field to print secured images, such as official
    stamps, which you are not legally permitted to save on your computer as
    regular pictures, but as *.dll files. The source types available for
    External Data fields include the values Procedure Name, Database,
    Formula and System Variable.
    To select an external data source type to print a fixed image:
    1. Choose Properties - Field > Content tab.
    2. Select Procedure Name in the Source Type field:
    3. Enter the name of the required *.dll file in the Procedure
       Name field.
    The *.dll file must be located in the extensions folder defined in
