If you want to extract some functionality out of the core and provide a new extension point so that plug-ins can provide an extension, read on.
Example: Let plugins implement how invoices are posted to FACCT.
Replace core code by call to service
- Navigate to Doc_Invoice.createFaccts()
- Insert the line
IInvoicePoster invoicePoster = Service.locate().getInvoicePoster(). Eclipse will highlight some errors, we will repeatedly use Code assist (Ctrl-1) to proceed. - Position the cursor on
IInvoicePoster, create new interface using code assist.- Create the interface in the package
org.adempiere.base - In this package, all core interfaces should resist.
- Create the (empty) interface and save.
- Create the interface in the package
- Back to Doc_Invoice, position the cursor on
getInvoicePoster(), create new method using code assist.- The new method is inserted in the interface IServiceLocator. Save it.
- Back to Doc_Invoice, insert the line
invoicePoster.post() - create new method post() using code assist.
- The method is inserted into the new interface
IInvoicePoster
- The method is inserted into the new interface
