This document provides instructions for creating a custom application in JDeveloper, adding required libraries, creating a RESTful web service, running the integrated WebLogic server, and testing the REST web service. The key steps are: 1. Create a custom application and Java class project in JDeveloper. 2. Add required Oracle API JAR files to resolve errors. 3. Right click the Java file and select "Create RESTful Service" to add annotations. 4. Run the service on the integrated WebLogic server and test it by sending requests and verifying records in backend tables.

1. Create Custom Application in Jdeveloper
OpenJdeveloper12.1.3.0.0 or 12.2.1.1.0 -File->New->ApplicationorNew Application
SelectCustomApplication
Enter the ApplicationName

2. Enter ProjectName andSelect‘Java’:
Leave the Defaults:

3. Your Applicationwithprojectwouldlooklike below,rightclickonthe Project‘Inv_API’andselect
New->JavaClass
Enter JavaClassName and leave itasdefaultorclick onthe Main methodcheckbox andpressOk

4. Your Java Classwouldbe asbelow,addthe code for invokingOracle PublicAPI:
Build the code required to call the Oracle Public API
AfterAddingthe code youmightsee the errorswith‘OracleTypes’

5. Add Libraries to the Project
To get ridof the errors,add the requiredJARFiles. Rightclickonthe project‘Inv_API’andselect‘Project
Properties’andclickon‘LibrariesandClasspath’andthenclickon‘AddLibrary’and addfollowing
libraries

6. Clickon ‘AddJAR/Directory’andaddthe JARFilesfromyourlocal machine
AfteraddingrequiredJarandlibraryfiles,clickOK

7. Save your work
Make sure youhave no Build-Issues

8. Create Rest Webservice
Rightclickon ‘Rest_Java.java’file andselect‘CreateRESTful Service’,andenterthe requiredinformation

9. Your applicationwithcode wouldlooklike below withthe annotationsaddedautomatically
Save All

10. Running the Integrated Weblogic Server
RightClickon ‘Rest_Java.java’andselect‘Run’,select‘JAX-RSWebService Runner’
IntegratedWebLogicServergetskickedoff andthe followingURLwouldbe generated
Clickon the TargetURL, HTTP AnalyzerWindow opens,enterthe parameters
Checkthe Interface table forthe TransactionInterface Id

11. AfterRestwebservice isrunyoushouldsee the recordinthe base table
Testing Rest Webservice
Clickon ‘SendRequest’afterenteringthe parameters
You shouldsee the message if the RestWebservice issuccessful

12. Nowverifyinginthe backend: Interface table recordgetspickedup
Checkingthe base table
