How to define a function/subroutine in JSP?

thanks.

The implicit object out is available only in scriplets writtin inside <% ... %> tags. And not inside declaration tags <%! ... %>
Thats is so because the implicit object out is a local variable in the _jspService( ) method of the servlet produced corresponding to your JSP.
For moredetails read the JSP specifications.
For your specific case, it seems you need to pass out as a parameter to your hello() method...
hello(javax.servlet.jsp.JspWriter out)

How to define recursive functions in JSP

Hi,
If anybody knows, how to to define recursive functions pls help. I am using an XML file for the creation of a tree menu. In order to display the menu, i have to use recursive functions...Also out.println throwing error in the function..
Thanks,
Philips

I do not have my Java book at work with me today so you'll have to bear with me. The following routine assumes that you can get some sort of branch object from your tree menu object (also assuming you have something like this). Furthermore, it assumes that the branch object can return some sort of collection of all leaves and branches on a particular branch through a made-up getLeaves() method call.
<%!
          public void displayLeaves(Branch branch)
               Iterator branches = null;
               branches = branch.getLeaves().getIterator();
               Object leaf = null;
               while( branches.hasMoreItems() )
                    leaf = branches.nextItem();
                    if(leaf instanceof branch)
                         displayLeaves((Branch) leaf);
                    else
                         out.println( ((Leaf)leaf).getValue() );
%>This code fragment should be just the logic you need to expand a tree as JSP output. To invoke this method all you have to do is pass the root branch element to the method from within your JSP. Please let me know if you need additional info.

ARFC : How to define the return subroutine ?

Hi,
In an ARFC how we will define a return subroutine?
call function 'Z_RFC_EXEC'
       starting new task g_task_name
       destination in group us_srvgrp
       performing <b>task_return</b> on end of task
do we have to define the subroutine task_return in the main program ? if so how to build it ?
Could we put an ARFC inside an OPEN CURSOR and CLOSE CURSOR ?
rgds,
abhilash

Hi abhilash,
1 do we have to define the subroutine task_return in the main program ? if so how to build it ?
Yes, in your se38 program itself.
in this manner.
<b>FORM task_return USING TASKNAME</b>
2. This code may help u (just copy paste_
3.
report abc.
DATA: INFO LIKE RFCSI,
Result of the RFC_SYSTEM_INFO function
      MSG(80) VALUE SPACE,
Exception handling
      RET_SUBRC like SY-SUBRC.

How to define Excel function using BEx formula

Hi experts,
May I know how to define the following Excel function using BEx formula?
IF(AND(Revenue<0,Cost<0),"N/A",(Profit/Lost/ABS(Revenue)))
Thanks!

for me its easy to implament logic with * and + rather than AND and OR respectively
((Revenue<0)(Cost<0))Value +((Revenue>0)(Cost>0)) ( Profit&Lost / ABS(Revenue))
As i have mentoned already,for Else case i have considered (Revenue>0) and (Cost>0) only.
Value can be a KeyFigure/Formula/formula variable/CKF/RKF
its not possible to type characters in the formula window so 'N/A'

RETURN TRUE ;
else
RETURN FALSE ;
end if;
END chk_notnull_blank;
======================
pls advice
thanks/kumar

You cannot define a generic argument in a function,
but you can overload several funtions with the same name and different types of arguments in a package,
in this way (not tested):
create table employees as
select employee_id ssn, first_name, last_name from hr.employees;
create or replace
PACKAGE chk
IS
cursor c is select first_name, last_name , ssn from employees ;
TYPE employee_type IS TABLE OF c%rowtype;
TYPE employee_ssn_type IS TABLE OF employees.ssn%TYPE;
TYPE employee_num_type IS TABLE OF number;
FUNCTION chk_notnull_blank ( colname employees.ssn%TYPE) RETURN boolean;
FUNCTION chk_notnull_blank ( colnames employee_type) RETURN boolean;
FUNCTION chk_notnull_blank ( colnames employee_ssn_type) RETURN boolean;
FUNCTION chk_notnull_blank ( colnames employee_num_type) RETURN boolean;
END chk;
create or replace
PACKAGE BODY chk
IS
FUNCTION chk_notnull_blank ( colname employees.ssn%TYPE) RETURN boolean IS
BEGIN
    if ( colname is NOT NULL and colname in ( -8E14, -7E14, -6E14, -5E14, -4E14, -3E14, -2E14, -1E14, -1E9 )) then
      RETURN TRUE ;
    else
      RETURN FALSE ;
    END IF;
END chk_notnull_blank;
FUNCTION chk_notnull_blank ( colnames employee_type) RETURN boolean IS
BEGIN
     FOR i IN colnames.FIRST .. colnames.LAST LOOP
        IF NOT chk_notnull_blank( colnames( i ).ssn )
        THEN
           RETURN FALSE;
        END IF;
     END LOOP;
     RETURN true;
END chk_notnull_blank;
FUNCTION chk_notnull_blank ( colnames employee_ssn_type) RETURN boolean
IS
BEGIN
     FOR i IN colnames.FIRST .. colnames.LAST LOOP
        IF NOT chk_notnull_blank( colnames( i ) )
        THEN
           RETURN FALSE;
        END IF;
     END LOOP;
     RETURN TRUE;
END chk_notnull_blank;
FUNCTION chk_notnull_blank ( colnames employee_num_type) RETURN boolean
IS
BEGIN
     FOR i IN colnames.FIRST .. colnames.LAST LOOP
        IF NOT chk_notnull_blank( colnames( i ) )
        THEN
           RETURN FALSE;
        END IF;
     END LOOP;
     RETURN TRUE;
END chk_notnull_blank;
END chk;I assumed in this example that if the argument of the function chk_notnull_blank is of the table (collection) type,
then the function returns true if all table elements pass the check, otherwise it returns false.

How to define Partner function!

I want to create a customer as a sold-to party in order to create a sales order.I have set up a account group name is internal sold-to party and use it by this customer,but at the tab of sales data I can't assign the partner function to this customer because of no possible entries exist for the field of PF!
What can i do ?THKS
Brian

Create your customer with the account group 0001-sold-to party.
In case, you have created your own account group, check as to how the same is created/maintained and assigned in Sales and Distribution-Basic functions-Partner Determination-set-up partner Determination.
Here one defines the rules that should be used to perform for automatic partner determination.
When a customer master record is created, the SAP system proposes the allowed partner functions for maintenance. The partners are copied from the sold-to party's customer master records into the sales documents, according to the rules one has defined.

Gaurav.

How to define a function that returns a void?

Hi all,
How can I define a custom function that returns a void?
My understanding is simple UDF can only return a string.
Is there any way around this limitation?
Thanks.

Hi all,
Thank you all for your kind responses.
The scenario I have is I need to insert the value of a particular field into a database table. E.g. MessageId, to keep track of the messages going through XI.
Naturally, such operations return void. These operations are already encapsulated in a custom jar file.
My purpose of using a UDF is solely to invoke the operation.
But I realized I each UDF has to have a return type, and the output of this UDF must be mapped to a node in the outgoing message.
Currently, my UDF returns an empty string, by using the implementation as below, I manage to perform my desired operation without affecting the result:
MessageId -- UDF -- CONCAT -
InstitutionCD_Transformed
InstitutionCode_____
But as you can see, this is not an elegant way of doing things.
That's why I'm seeking alternative solutions for this problem.
Bhavesh, you mentioned something about doing the operation in the initialization/cleanup section.
Can you please explain more?
Thanks.
Ron

How can i call userdefined java functions in a JSP ?

Hi,
i want to define some functions in a java class. is it possible to use these functions in a jsp ? how can i achieve this ?

I suggest you call the function you want in either a custom tag or in the servlets/struts/jsf,... classes you are using.
If you dont want those and you prefer scriplets then 2 step,s.
First import the class then call it.

How do i call a function within the jsp?

Hi,
What i am doing is now allow a user to type in comment and when the user click on "Add" button, it will call my function and write to a txt file.How can i call a custom jsp function within my jsp page or what is the correct way to do this?
[My current codes]
<form name="SubmitEvent" method="post" action="addComment()">
</form>
function addComment()
System.out.println("Entered Add Comment function");
Thanks for your help!

You can define a Java Bean (I presume you know the rules to write a Java Bean) and send the read value as parameter to the Bean and then call a function in the Bean from the JSP.
