Hi,

ex: HashMap m = new HashMap();

First of all I would say that there is no "add" method for Hashmap, its put
secondly try this

How to use the method for field-exit to trigger the workflow?

Dear all,
     I want the workflow to trigger , when ever the check box for DELIVERY COMPLETED is checked in ME22N .
     I have developed a method in SE18 for the corresponding field and defined function module SWE_EVENT_CREATE with BOR bus2012 and event CHANGED.
    Now how to use this method to make my workflow to trigger?Shall I create an event in delegated bus2012 and can I call this method?
Thanks and regards,
S.Suresh

Hi
You want to place your method which is defined for particular filed.right?
For that you can go for BADI. First you check whether any badi is getting called form that tcode ME22N. Then to place your method, implement that BADI. So whenever that BADI is getting called, it will call your event. Through Event workflow will be getting triggered.

How to use getContent() method in custom JSP Provider to display a HTML Pag

Hi,
If anybody knows how to use getContent() method to use in custom jsp providers (developed by ourselves) so that it can be used to retrieve a jsp page (a simple html page) ..
I want the code in the provider java file to for the getContent method...
Pls. get back to me asap....if any body has implemented a custom jsp provider...as it's urgent...
I have alreday placed the JSP file in the directory structure /etc/opt/SUNWps/desktop/default/channel_dir..But still the jsp is not being displayed..
Pls get me the getContent() method code to retrive the JSP file..
satyabrata

Hi,
You don't have to do anything in the custom JSPProvider's getContent method except the call { return super.getContent(request,response); } . If all you want is just to show your jsp, then create a channel from the default JSPProvider, and edit the property contentPage of that channel from samplecontent.jsp to your jsp name, save the changes and login again. You should see your JSP.

Problems using GET method in JSP

Hi,
I had some problems using GET method in JSP.
I'm using Apache web server 1.3 and Tomcat 3.3.1 in windows 2000.
And I'm using language English and Korean.
When I send messages using POST method, all is good
But when I send message using GET method, English is good, but Korean is not good.
I tried to encode using
URLEncode.encode(str, "UTF-8")
and decoding it using
URLDecode.decode(request.getParameter(tag), "UTF-8")
but it didn't work.
How can I receive request including Korean using GET method in JSP?
If anyone have solutions, please let me know.
thanks.

thanks.This problem appears, when one use UTF-16 encoding in JSP - am I right?
If so there are two solutions:
1) Temporary: Use "UTF-8" - or any other 8 bit encoding scheme and
encode Korean symbols with "&1234;" kind of escapes - though it
may not work
2) Absolute: get my piece of code, which I have managed to write
just a month ago resolving absolutely similar problem with UTF-16
in code using Chinese/Russian/English encodings
But I wouldn't say that it's costs 10 DDs :) - it's much more
expensive... So try 1st variant if it wouldn't help - let me know.
I'll figure :)

How to use Aggregations Method generated by WIZARD

Hi All,
          I used ABAP wizard to develop I report.
This wizard generated one class and method as below
zcl_bt_alv_template=>factory(
                 exporting im_syrepid = sy-repid
                            im_lheader = gv_title
                            im_allowls = abap_true " Allow layout save
                 importing ex_alvo    = r_alv_template
                 changing   ch_datatab = it_efficiency ).
Inside this Factory Method there is one method for aggregations.
ex_alvo->r_aggregations = ex_alvo->r_table->get_aggregations( ).
How to use this Method for getting aggregations for some fields.
Thanks,
Prasad.

Hi Patel,
               I am getting DUMP for this.
Its saying Access via 'NULL' object reference not possible.
Patel when I am double clicking the
aggregation = if_salv_c_aggregation=>total
This if_salv_c_aggregation is not having any methods.
So may be the dump is coming.
The dump is
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: "R_AGGREGATIONS").
Thanks,
Prasad.

Validations when we use GET method

Hi Team,
I am using GET method with the following URL(example)
http://IP:8080/ords/schema_name/office/users/{user_id}
URI template : office/users/{user_id}
method:get
source type : Feed
Source : select * from emp where empno = :user_id;
Using the above URL I am able to get all the specified user details in the browser.
I want to add the validations to the service now, and response should be user defined.
Ex : when user not in the database
then respond with the error code and error name in JSON format ex:
items:
error code : 404
message: "somthing wrong"
I am not sure how we can achieve this functionality when we use SQL query.
Please suggest any possible solutions for this.
thanks
Chandran

grant dba_users view to apex and change the sql like this:
select * from emp where empno = :user_id and exists (select 1 from dba_users where username=:user_id);

How to use protected method in jsp code

Could anyone tell me how to use protected method in jsp code ...
I declare a Calendar class , and I want to use the isTimeSet method ,
But if I write the code as follows ..
========================================================
<%
Calendar create_date = Calendar.getInstance();
if (create_date.isTimeSet) System.out.println("true");
%>
============================================================
when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

The only way to access a protected variable is to subclass.
MyCalendar extends Calendar
but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
cal.isSet( Calendar.HOUR );

How to use secondary method in workflow?

Hi friends,
can anyone plz let me know how to use secondary methods in workflow? it would be helpful if u explain with an example..
thanks and regards,
Arun.S

Hi Arun Kumar,
The Sec Method can be used in the user decision step. The secondary methods are executed along with the user decision step. You have 3 options. Either execute a secondary method before executing the user decision step or after execution of user decision step or while executing the user decision.
For this define the methods either in Methods before execution of workitem execution to execute it before user decision step or Methods after execution of workitem so as to execute it after the execution of user decision.
In order to execute a method along with user decision step execution use secondary methods (amodal call.)
Let me know if you have any queries.
Regards,
Raj

How to use this method in JSTL?help me please!

I know I can use "<C:set >" like as
<c:set var="clabel3" value="${portalCustomizeBean.portalPage}"/> ,
but now I want to use one method of portalCustomizeBean object not a attribute of it !!!!!
who would tell me how to use?
this is wrong in my code:
<c:set var="clabel" value="${portalCustomizeBean.currentPageLabel}"/>
<c:set var="clabel3" value="${portalCustomizeBean.toEntitiesExceptSpaceEscape(clabel)}"/>
but how to use "toEntitiesExceptSpaceEscape" method in JSTL?????

Why can't you just assign the method's return value to a variable and then print that? A bit of scriptlet code will do the trick. (As much as we all hate to use scriptlet code.)
I believe you'll be able to do what you want in the 1.1 standard JSTL, but for now this will suffice. - MOD

Now that Web Services is around, I'd look at possibly implement a Web Service call in your applet, which can then be given back any object(s) on return. Set up your server side to handle Web Service calls. In this way, you can break the applet out into an application should you want to (with very little work) and it will still function the same

How to use protected method of a class in application

Hi,
will u please tell me how to use protected method of class in application. (class:cl_gui_textcontrol, method:limit_text)
Thanks in advance,
Praba.

Hi Prabha,
You can set the maximum number of characters in a textedit control in the CREATE OBJECT statement itself.
Just see the first parameter in the method . I mean MAX_NUMBER_CHARS. Just set that value to the required number.
Eg:
data: edit type ref to CL_GUI_TEXTEDIT.
create object edit
exporting
    MAX_NUMBER_CHARS       = 10
   STYLE                  = 0
   WORDWRAP_MODE          = WORDWRAP_AT_WINDOWBORDER
   WORDWRAP_POSITION      = -1
   WORDWRAP_TO_LINEBREAK_MODE = FALSE
   FILEDROP_MODE          = DROPFILE_EVENT_OFF
    parent                 = OBJ_CUSTOM_CONTAINER
   LIFETIME               =
   NAME                   =
EXCEPTIONS
    ERROR_CNTL_CREATE      = 1
    ERROR_CNTL_INIT        = 2
    ERROR_CNTL_LINK        = 3
    ERROR_DP_CREATE        = 4
    GUI_TYPE_NOT_SUPPORTED = 5
    others                 = 6
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
In this case, the max: number of characters will be set to 10.
I hope your query is solved.

SP.
