- 11. Use Case 1: SQL statement Find string from string id in SYSIBM.SYSXMLSTRINGS table 11 SELECT STRINGID, SUBSTR(STRING,1,60), IBMREQD FROM SYSIBM.SYSXMLSTRINGS;
- 12. Client development using studio • Create a new MobileFirst Project: File>New>MobileFirst Project, select “Hybrid Application” 12 index.html main.js
- 13. Sever side Pre-req for SQL adapter Add DB2 info to server.xml 13 sever.xml
- 14. Server Side development – Creating a SQL Adapter • File>New>MobileFirst Adapter 14 Hello2DB2Adapter.xml
- 15. Creating a SQL Adapter – cont’d Hello2DB2Adapter-impl.js • deploy a adapter: Right-Click the adapter>Run As>Deploy MobileFirst Adapter • Test a adapter Right-Click the adapter>Run As>Call MobileFirst Adapter
- 16. Test a SQL Adapter Right-Click the adapter>Run As>Call MobileFirst Adapter Result: What is this?
- 17. How to use the adapter result? main.js
- 18. Build all Environments • Right click <apps>Run As>Build All Environments • Select iPhone, iPad, Android phones and tablets 18
- 19. MobileFirst Console • Right Click <project> > Open MobileFirst Console 19
- 21. Run on Android Native Emulator • (require Android SDK, ADT Eclipse plug-in, creating Android Virtual Device) • Right Click <project><apps>Android>Run As>Android Application 21
- 22. Use Case 2: Calling a Stored Procedure 22 RUNSTATS
- 23. RUNSTATS – SQL adapter 23 RunstatsSQLAdapter.xml RunstatsSQLAdapter-impl.js
- 24. Call external REST API – Yahoo Weather API (i.e. SQL Adapter is NOT needed) 24 Main.js
