  3. 3. Working with Custom faults Q)What are custom faults ? A) Custom faults are those faults which is defined by developer for certain limitations . Summary: Aim of custom fault project is that to catch those faults which are defined by developer at the time of service development so here in topper student project when someone input wrong student marks i.e input marks of individual subject should not be smaller than zero & greater than hundred , so this kind of restrictions are provided by developer so if wrong marks input then it shows custom fault message that input marks is invalid . Step wise procedure on topper student project with fault handling (custom fault): Step 1: Open ProcessStudent Project & under it open ProcessStudentProcess.bpel as shown below Step 2: In design mode Drag & Drop Switch Activity so that bpel can set condition www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 3
  4. 4. Step 3: Click on condition part to set if condition for switch activity Motive of Switch Activity Our motive is setting condition that if marks are smaller than zero or greater than hundred then throw custom/business fault & also reply this fault as output else choose otherwise condition if input marks are correct & keep all components inside this otherwise condition Step 4: Click on Expression builder shown below : www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 4
  5. 5. Step 5: Click on lang1 marks ---> insert into expression ---> Logical Function ----> smaller ---> insert into expression ---> 0 (zero) or Click on lang1 marks ---> insert into expression ---> Logical Function ----> greater ---> insert into expression ---> 100 (hundred) or Click on lang2 marks ---> insert into expression ---> Logical Function ----> smaller ---> insert into expression ---> 0 (zero) or Click on lang2 marks ---> insert into expression ---> Logical Function ----> greater ---> insert into expression ---> 100 (hundred) or Click on lang3marks ---> insert into expression ---> Logical Function ----> smaller ---> insert into expression ---> 0 (zero) or Click on lang3 marks ---> insert into expression ---> Logical Function ----> greater ---> insert into expression ---> 100 (hundred) as shown below www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 5
  6. 6. Step 6: Click on Ok . Step 7 : Drag & drop Assign Activity & Rename It as AssignCustomFault : www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 6
  7. 7. Step 8: Drag & drop Throw Activity "This activity throws the fault data to the catch activity" Step 9: Rename throw activity as ThrowInvalidMarksFault www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 7
  8. 8. Step 10: Double Click On Throw activity & Edit Throw activity , Click On Browse icon shown below Step 11: Observe that there is no fault message under Project WSDL Files in ProcessStudentProcess.wsdl so first create fault message inside ProcessStudent wsdl file for custom fault . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 8
  9. 9. Step 12: Observe ProcessStudentProcess.wsdl in design mode that inside port type it has only two process one is Input & other output but not containing Fault as its third process so create it in source mode . Step 13:Now edit this wsdl in source mode www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 9
  10. 10. Step 14: Edit PortType as shown below : <wsdl:fault message="InvalidStudentMarksFaultMessage" name="Error"/> www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 10
  11. 11. Step 15: Edit Message Type Definition as shown below : <wsdl:message name="InvalidStudentMarksFaultMessage"> <wsdl:part name="InvalidStudentMarksFault" element="err:Error"/> www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 11
  12. 12. Step16: Import Error.xsd from oramds , open resource palette ---> SOA-MDS-->dev mds conn -->apps--->Error.xsd to get schema location of error.xsd click once on it & use ctrl +shift+c then paste inside schemalocation , delete all before apps & write oramds:/ before apps . then copy namespace from error.xsd & paste here inside namespace . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 12
  13. 13. Step 17: Register namespace of Error.xsd with prefix "err" . xmlns:err="http://www.bispsolutions.com/training/soa/schema/Student" www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 13
  14. 14. Step 18: As completed editing wsdl click on design mode & observe fault process Explore fault on clicking [+] sign & see that it contains InvalidStudentMarks faultMessage associated with its part . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 14
  15. 15. Step 19: Click on Imports & check imported xsd Step 20: click on Schema mode to see included xsd . Step 21: Open ProcessStudentProcess.bpel & Edit Throw activity again www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 15
  16. 16. Step 22: Now observe that this time wsdl contains Invalid studentMarksfaultMessage click on it & hit ok . Step 23: Create Variable as shown below & click OK www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 16
  17. 17. Step 24: Check detail & hit OK . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 17
  18. 18. Step 25: Check variables by clicking on icon . Step 26: Check that all QName is associated with its prefix , so observe here that InvalidStudentMarksFaultVar does not contains its prefix so click on QName & edit variable , it should be message type , click on Browse www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 18
  19. 19. Step 27: Click on that InvalidStudentMarksFaultMessage & click OK Step 28: Again Check variables by clicking on icon . Step 29: Click on assign custom fault & start assigning fault data www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 19
  20. 20. Step 30: To assign faultCode click on expression Drag & Drop on faultCode as shown below Step31: Write Expression i.e fault code as 'FMW-002' www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 20
  21. 21. Step 32: Similarly severity as 1 Step 33: Select Date Functions & under it select current-date-Time then insert intoExpressionthen click ok Step 34: Similarly Detail as 'INVALID MARKS SELLECTION' www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 21
  22. 22. Step 35: For CompositeName click Advanced functions ----> getCompositenName then Step 36: For ComponentName click Advanced functions ----> getComponentName then insert into Expression www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 22
  23. 23. Step 37: For CompositeInstanceId click Advanced functions ----> getCompositeInstanceId then insert into Expression Step 38: Observe all assigned values www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 23
  24. 24. Step 39: Drag & drop Reply Activity & click twice on it to edit reply as shown below: Step 40: Edit Reply as shown below : www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 24
  25. 25. Step 41: Click on compile icon to compile the bpel process www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 25
  26. 26. Step 42: Build successful Step 43: Deploy project by clicking ProcessStudent to devsoa www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 26
  27. 27. Note: Before Deployment Start Weblogic Admin Server as discussed in my previous document Oracle Soa Part IV Doc. Step 44: Click on Browser icon shown below: Step 45: Start your enterprise manager by writing url http: //localhost:7001/em/ www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 27
  28. 28. Note : Here localhost is application server & 7001 is a port in which enterprise manager is running. Step 46 : Login using credentials User Name :weblogic Password : welcome1 click on login Step 47: We have successfully login inside Enterprise manager 11g (Farm_dev_soa) we can clearly observe here that admin server is up & all deployment status is also up it means that our admin server is running . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 28
  29. 29. Now In left pane of window under Farm_dev_soa click on SOA radio button now again expand & under default we can easily see all the deployed projects. Click on Processstudent twice Step 48: Click on TEST & create instance Step 49:Explore payload & select tree view www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 29
  30. 30. Step 50: Fill all blank spaces as shown below Step 51: Click on Test Web Service And get Response shown below: Step 52: Now since input lang1 marks is 150 & so it displays custom error or InvalidStudentMarks Error as shown below .Click on close . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 30
  31. 31. Step 53 : Parse wsdl & again try with these inputs shown below : Click on Test Web Service Step54 : Observe response without error because this time all input lang marks are between 0 & 100. www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 31
  32. 32. Step 55: All instances are completed & instance 320002 is completed with custom fault & instance 320003 is completed without errors . NOTE: Now how we catch these faults through invoking service , next steps are concentrated on this question in which calling service is TopperStudent Service . Step 56: Open Topper Student Process . bpel click on Add catch all activity shown below www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 32
  33. 33. NOTE: Catch activity can catch only system faults where as catch all activity catches business fault Step 57: Click on source mode .Copy all activies of catch & paste inside catch all block in sorce mode www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 33
  34. 34. Step 58: Copy catch as shown below Step 59: Paste inside Catch all activity www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 34
  35. 35. Step 60: Change into design mode & save by clicking save icon Step 61: Drag & drop Scope Activity as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 35
  36. 36. Scope Activity : This activity consists of a collection of activities that can have their own local variables , fault handlers, compensation handlers and so on . A scope activity is analogous to a block { } in programming language .Each scope has a primary activity can be complex structured activity that, with many nested activities within it to arbitrary depth. The scope is shared by all the nested activities . Step 62: Now drag & drop all components inside scope activity as shown below : www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 36
  37. 37. NOTE: Since we have made changes in ProcessStudentProcess.wsdl in ProcessStudentProject hence also need changes in imported ProcessStudentProcess.wsdl in TopperStudent Project so that catch activity catch this custom fault as remote fault in TopperStudentProject . Step 63: Open ProcessStudentProcess.wsdl in TopperStudentProject by clicking on it & observe in design mode that it does not have fault process . Aim : Our aim is to copy the required content from 'M wsdl ' to 'N wsdl' Where M= 'ProcessStudentProcess.wsdl' in ProcessStudent Project & N= ' 'ProcessStudentProcess.wsdl' in TopperStudentProject Step 64: Copy imported Error.xsd from M.wsdl as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 37
  38. 38. Step 65: Paste imported Error.xsd to N.wsdl as shown below: Step 66:Copy registered namespace from M.wsdl as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 38
  39. 39. Step 67: Paste registered namespace from N.wsdl as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 39
  40. 40. Step 68: Copy MessageType from M.wsdl as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 40
  41. 41. Step 69: Paste MessageType to N.wsdl as shown below: www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 41
  42. 42. Step 70:Copy PortType from M.wsdl as shown below: Step 71: Paste PortType to N.wsdl & save all by clicking save icon www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 42
  43. 43. Step 72: Click N.wsdl in design mode & observe that now created Fault as process . Step 73: Add Terminate activity to terminate catch process as shown below & save all . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 43
  44. 44. Step 74: Click on compile icon to compile the bpel process Step 75: Compilation successful with o errors & o warnings . Step 76 : Deploy project by clicking TopperStudentProject. www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 44
  45. 45. Deployment Finished Note: Before Deployment Start Weblogic Admin Server as discussed in my previous document Oracle Soa Part IV Doc Step 77 : Click on Browser icon shown below: Step 78: Start your enterprise manager by writing url http: //localhost:7001/em/ www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 45
  46. 46. Note : Here localhost is application server & 7001 is a port in which enterprise manager is running. Step 79 : Login using credentials User Name :weblogic Password : welcome1 click on login Step 80: We have successfully login inside Enterprise manager 11g (Farm_dev_soa) we can clearly observe here that admin server is up & all deployment status is also up it means that our admin server is running . Now In left pane of window under Farm_dev_soa click on SOA radio button now again expand & under default we can easily see all the deployed projects. Click twice on TopperStudentProject . www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 46
  47. 47. Step 81: Click on TEST & Create instance Step 82: Input Student array size =2 www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 47
  48. 48. Step 83: Scroll down page & Provide required input of a students www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 48
  49. 49. Step 84: Click on Test Web Service And get Response shown below: Step 85: Now we can see that catch activity catch the fault & replied to the client as Faultdata Response but here catch activity cached it as remote fault thats why fault code is FMW-0001 & detail of custom fault is displayed inside Detail as FMW-002 , <Detail>Invalid marks </Detail> as shown below : Step 86: Check flow trace www.bispsolutions.com www.bisptrainigs.com www.hyperionguru.com Page 49
