How to compose user-defined Event?
I want to realize a event and event listener pair to work, the basic idea as follows:
interface ConditionChangeListener extends EventListener {
public void conditionChange(ConditionChangeEvent cce) {}
class ConditionChangeEvent extends EventObject {
class EventHandler implements ConditionChangeListener {
public void conditionChange(ConditionChangeEvent cce) {
// do my work;
class EventSource {
// how can I fire a ConditionChangeEvent?
}but how can I fire a ConditionChangeEvent in my code like above?
Thanx
class ConditionChangeEvent extends EventObject {[...]
"yourEventQueue".dispatchEvent( "new
ConditionChangeEvent" )
or
"yourEventQueue".postEvent( "new ConditionChangeEvent"
}Is this enough or don't you know how to get
"yourEventQueu" or is your problem how to create the
new ConditionChangeEvent?Sorry for this answer - every time I see the word event I think one must talk about AWTEvent. But this is not what you are doing! So what you need is the whole
"event generator idiom"
described at the page
http://www.javaworld.com/javaworld/jw-09-1998/jw-09-techniques-p2.html
Hope now this is a real help for you

HI ALL
JUST WANT TO KNOW CAN WE HANDLE USER DEFINED EVENTS BY SETTING USER DEFINED PF -STATUS IN ALV
FOR EG :
call function 'REUSE_ALV_LIST_DISPLAY'
exporting
i_callback_program = gd_repid
I_CALLBACK_PF_STATUS_SET = K_STATUS
I_CALLBACK_PF_STATUS_SET = 'ZTEST1'
i_callback_top_of_page = 'TOP-OF-PAGE' "see FORM
i_callback_u ser_command = 'USER_COMMAND'
I_CALLBACK_USER_COMMAND = K_USER_COMMAND
IS_LAYOUT = GD_LAYOUT
IT_SPECIAL_GROUPS = KR_SP_GROUP
i_grid_title = outtext
is_layout = gd_layout
it_fieldcat = fieldcatalog[]
it_special_groups = gd_tabgroup
IT_EVENTS = GT_XEVENTS
i_save = 'X'
IS_VARIANT = K_VARIANT
IT_EVENTS = KR_EVENTS[]
is_variant = z_template
tables
t_outtab = it_ekko
exceptions
program_error = 1
others = 2.
if sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
endform. " DISPLAY_ALV_REPORT
I HAVE MY OWN PF-STATUS IN WHICH I HAVE CREATED 1 BUTTON WHEN I GET THE OUT PUT AND CLICK ON THAT BUTTON THAN IT GOES TO STANDARD PROGRAM ....I WANT WHEN IT CLICK ON THAT BUTTON IT GOES TO MY Z PROGRAM HOW CAN I DO THAT ...
IF POSSIBLE PLZ PROVIDE CODE OR SOME EXAMPLE .
THANKS
TARANU can have button on application toolbar.
You just have to use the new pf status in your report program.
You should copy the 'STANDARD' GUI status from program SAPLKKBL using transaction SE90 >Programming SubObjects> Gui Status.
Execute this transaction to get to next screen. select status using checkbox. click on GUI Status --> Copy.
Enter your Z program name and the name you what for this status - you can keep it as 'STANDARD' to be simple.
Then you can edit the new status to add or delete buttons. This will also bring in the standard SAP ALV functionality.
Have a look at below code for using the new status.
TYPE-POOLS: slis.
DATA: i_qmel LIKE qmel OCCURS 0.
data v_repid type repid.
SELECT * FROM qmel INTO TABLE i_qmel.
v_repid = sy-repid.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = v_repid
<b>I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'</b>
I_CALLBACK_USER_COMMAND = 'USER_COMMAND'
i_structure_name = 'QMEL'
TABLES
t_outtab = i_qmel
EXCEPTIONS
program_error = 1
OTHERS = 2.
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
<b>form set_pf_status using rt_extab type slis_t_extab.
set pf-status 'TEST'.
endform.</b>
FORM user_command USING ucomm LIKE sy-ucomm
selfield TYPE slis_selfield.
data lv_ucomm type sy-ucomm.
lv_ucomm
= sy-ucomm.
CASE lv_ucomm.
WHEN 'BUTTON'. "Double Click line Item
**Write ur functinality here
endcase.
endform.
Also have a look at below links.

How to import user defined class in UIX page?
Does anyone know how to import user defined class in UIX page so that the class can be called in the javascript in the UIX ?
Thks & Rgds,
Bennywhat you are referring to is not javascript.
it is JSP scriptlets. These are very different.
In order to keep a strict separation between View and Controller, it is not possible to run arbitrary java code from within your UIX code.
However, you can run java code from within a UIX event handler; see:
http://otn.oracle.com/jdeveloper/help/topic?inOHW=true&linkHelp=false&file=jar%3Afile%3A/u01/app/oracle/product/IAS904/j2ee/OC4J_ohw/applications/jdeveloper904/jdeveloper/helpsets/jdeveloper/uixhelp.jar!/uixdevguide/introducingbaja.html
event handler code is run before the page is rendered. -

U can define it the the PF-STATUS ( Menu for ALV ).
For that u have to define it in the EVENTCAT.

call function 'REUSE_ALV_EVENTS_GET'
exporting
i_list_type = 0

list_type_wrong = 1
others = 2.
if sy-subrc <> 0.

with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
clear i_event.
read table p_i_eventcat with key name = slis_ev_top_of_page into
i_event.
if sy-subrc = 0.
move 'TOP_OF_PAGE' to i_event-form.
append i_event to p_i_eventcat.

move 'USER_COMMAND' to i_event-form.
append i_event to p_i_eventcat.
endif.
And in the DISPLAY
call function 'REUSE_ALV_GRID_DISPLAY'

i_callback_program = v_progname
i_callback_pf_status_set = 'SET_PF_STATUS'
i_callback_user_command = 'USER_COMMAND'
i_callback_top_of_page = 'TOP_OF_PAGE'

endif.
*MENU SETTINGS.
form set_pf_status using rt_extab type slis_t_extab.
set pf-status 'ALV_MENU'.
endform. "SET_PF_STATUS

Now double click on ALV MENU nad u can create a button in the application bar.

How to use user-defined packages in JAX-RPC web service
I am trying to use Object of my class located in my package in jax-rpc webservice,the code is
package supercomputer;
import Hello.*;
public class SuperImpl implements SuperIF
public String sendParam(String data)
Temp ob=new Temp();
int i=ob.get1(10000);
return data+"returned by supercomputer";
Temp is located in Hello package,I have jar the Hello package as Hello.jar and has set its classpath in targets.xml of Ant tool.
The code compiles well and service is deployed successfully,but when i try to call the service from the client its gives me following error.
[echo] Running the supercomputer.SuperClient program....
[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:357)
[java] at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:228)
[java] at supercomputer.SuperIF_Stub.sendParam(SuperIF_Stub.java:60)
[java] at supercomputer.SuperClient.main(Unknown Source)
I dont know if it deploys why it gives error on client side.
Please tell how to use user-defined packages and class in jax-rpc service code ,i am not talking about passing user-defined parameters i am just talking about making objects of user defined classes in jax-rpc service.I think there is some problem in classpath.
Please guide me in doing that.
Thanks,
FarrukhFarrukh,
I don't know if your error is about a missing class from your custom package, ... what track did you followed to say that?
To use your package in the implementation of you web service, you should only follow the rules of making a web application: put your package jar in your \lib directory inside WEB-INF/ or your package classes unjared in classes (also in WEB-INF/).
As I already said, I have doubts that your error should be originated from a missing class from your package, but:
-try to see the logs (errors?) when you deploy your web service that could give a hint about the problem.
-try to see if you can access your endpoint through your browser to see if there is a online status
-display your config/WSDL file, and the steps you did to build your web service.

How to map user-defined fields in XML communication on SRM site
Hi All!
We use the External sourcing scenario and we transfer requirements from ERP in SRM through XI (PurchaseRequestERPSourcingRequest_In)
We should transfer the user-defined fields, but we can not map it in SRM site.
We have enhanced enterprise service in XI, have realized BADI PUR_SE_PRERPSOURCINGRQCO_ASYN on ERP site.
I see the XML message with ours z-fields in tr. SXI_MONITOR (into SRM), but I can not find it in BBP_PDISC.
We try to use BADI BBP_SAPXML1_IN_BADI (there is no method for SC), and BADI /SAPSRM/BD_SOA_MAPPING (z-fields is empty)
Someone can tell how to map user-defined field for SC?
Thanks in advance
Evgeny IlchenkoHello, Julia
We have found solution our problem
We have enhanced standard service in a new enhancement name space and defined own enhancement elements in our namespaces. Then these enhancement elements refered to the SAP standard Enterprise Service.
But In our new interfaces were different XML namespaces
When we have correct an error we could use the next BADI
on ERP site: PUR_SE_PRERPSOURCINGRQCO_ASYN
on SRM site: /SAPSRM/BD_SOA_MAPPING
