Presentation on how to Integrate the old and new Oracle technologies. Communicate from Forms to APEX and v.v. (Demo movie at the end of the presentation)

9. Introduction APEX 3.2 : Forms conversion Thechallenge of converting Simple Forms (60%) Moderate Forms (30%) (Very) Complex Forms (10%) Top 10 % project start project finish

10. The concept comes from… OraFormsFaces Thank you Wilfred!

12. PL/SQL Procedure

13. URLhttp://localhost:7778/forms/frmservlet?config=apex&module=orders

14. Embed a Form in APEX

15. Embed a Form in APEX APEX PAGE APEX REGION ORACLE FORM

17. Modify & Set

18. OuterDiv Width & Height

19. InnerDiv Width & Height

20. Applet Width & Height

21. Applet Margins

22. Address Applet by adding an ID="formsapplet" line

23. Settings browser dependent

24. Use same background color<div id="outerdiv" style="overflow:hidden; border-style:none;"> <div id="innerdiv" style="overflow:scroll; border-style:none;"> #BODY# </div> </div>

25. VisualIntegration

27. Attach a common library to your Form

28. Create procedure runJavascriptRequirement : When I move through a list of Products (Oracle Form), I want to see who bought it and where the customer is located. PROCEDURE runJavascript( pScript varchar2) IS BEGIN web.show_document('javascript:'||pScript, '_self'); END; web.show_document( ‘javascript:showOnMap()’, ‘_self’);

30. Create procedure TriggerApexPROCEDURE TriggerApex( pTrigger varchar2 ) IS BEGIN if name_in('system.current_form') = 'PRODUCTS' then if pTrigger = 'WHEN-NEW-RECORD-INSTANCE' then -- Requery APEX Reports region with parameter on Page 9 -- & Show the data on the Map runJavascript('refreshReport('|| name_in('PRODUCTS.PRODUCT_ID')|| ', ''P9_PRODUCT_ID'');showOnMap();'); end if; end if; END; TriggerApex('WHEN-NEW-RECORD-INSTANCE');

31. Communicate from Forms to APEX

32. Communicate from Forms to APEX APEX PAGE APEX REGION APEX REGION web.show_document APEX Form ORACLE FORM APEX Report APEX Chart

33. Communicate from APEX to Forms Requirement : When I click on a customer in a report, I should be able to edit the customer data – using our current (very complex) Form. When I save the changes the report should be updated immediately.

35. raiseEvent procedure – extend the Forms runtime

36. CommunicatorBean – receive external events

38. raiseEvent triggers (Bean’s) WHEN-CUSTOM-ITEM-EVENT

39. WHEN-CUSTOM-ITEM-EVENT calls execEvent

40. execEvent handles the request

41. Add code to TriggerApex procedure in library to refresh reportfunction queryCustomer( pCustId ) { //Setting Customer Id in Form and Requery execFormAction( 'execute_query', pCustId) } function execFormAction(pAction, pParam) { //Raising an event in Forms //Execute the Action (like 'execute query') $x('formsapplet').raiseEvent(pAction, pParam ); } PROCEDURE execEvent IS BeanEventDetailsParamList; ParamType number := text_parameter; Event varchar2(1000); Payload varchar2(1000); begin BeanEventDetails := get_parameter_list(name_in('system.custom_item_event_parameters')); get_parameter_attr(BeanEventDetails, 'Event', ParamType, Event); get_parameter_attr(BeanEventDetails, 'Payload', ParamType, Payload); if name_in('system.current_form') = 'CUSTOMERS' then if upper(event)='EXECUTE_QUERY' then set_block_property('DEMO_CUSTOMERS' , DEFAULT_WHERE, 'WHERE CUSTOMER_ID = '||payload ); execute_query; end if; end if; end; if pTrigger = 'POST-DATABASE-COMMIT‘ then -- Requery APEX Reports region with pValue, pField parameters runJavascript('refreshReport('''', '''')'); end if;

42. APEX REGION Communicate from APEX to Forms APEX PAGE Extended Forms Applet : raiseEvent APEX REGION APEX REGION web.show_document APEX Form CommunicatorBean / PJC ORACLE FORM APEX Report WHEN-CUSTOM-ITEM-EVENT APEX Chart PJC Library

44. HTML mustbe 100% identical

45. Start up the sameFormevery time (landing)

46. Pass the ‘real’ Form name to the landing form

47. Use WHEN-APPLET-ACTIVATED event to callthatForm

48. Details are in Wilfred’sdoc!! if upper(event) = 'WHEN-APPLET-ACTIVATED‘ then while true loop -- get the form name set_custom_property('BLK_PJC.PJC', 1,'EvalExpression','$v("CALL_FORM_NAME")'); formName := get_custom_property('BLK_PJC.PJC', 1, 'EvalResult'); call_form(formName); appletActive := get_custom_property('BLK_PJC.PJC', 1, 'AppletActive'); if appletActive = 'FALSE‘ then exit; end if; end loop; end if;

51. SUNJRE version (1.6.05)

52. < 10 or

53. switch off“Enable next-generation Java Plug-In

54. Focus and Sticky Cursor Issues

56. web.javascript_eval

57. WHEN-CUSTOM-JAVASCRIPT-EVENT

58. legacylifecycle

60. ‘fixed’ user in formsweb.cfg

61. pass APEX credentials(DB Auth.) to the Form

62. use SSO

63. login into Forms (once)http://localhost:7778/forms/frmservlet?config=apex&userid=&APP_USER./&P101_PASSWORD.@XE

64. Conclusions Thechallenge of converting Simple Forms (60%) Moderate Forms (30%) (Very) Complex Forms (10%) Top 10 % project start project finish

65. Conclusions Convert the major part at once Convert the rest when necessary/possible So reducing effort – (re)build and test money risk But you still need the Forms Server ($) Top 10 % project start project finish

66. Coming soon…. Whitepaper on OTN In cooperation with Iloon Ellen (@ Oracle)
