Now you have completed your ExternalFileServices reusable part, it's time to test it.
Create a server module called TestFileServicesModule and add the following code to the server module:
* Fields
Define Field(#Fld_SourcePath) Type(*NVARCHAR) Length(1000)
Define Field(#Fld_TargetPath) Type(*NVARCHAR) Length(1000)
Define Field(#Fld_Message) Type(*NVARCHAR) Length(2000)
* Server routine
Srvroutine Name(TestFileCopy)
Field_Map For(*INPUT) Field(#Fld_SourcePath) Parameter_Name(SourcePath)
Field_Map For(*INPUT) Field(#Fld_TargetPath) Parameter_Name(TargetPath)
Field_Map For(*OUTPUT) Field(#Fld_Message) Parameter_Name(Message)
* Create an instance of the FileServices reusable part
Define_Com Class(#ExternalFileServices) Name(#Services)
* Create an instance of the invocation status object
Define_Com Class(#ExternalServiceInvocationStatus) Name(#Status)
* Invoke the Copy method
#Services.Copy SourcePath(#Fld_SourcePath) TargetPath(#Fld_TargetPath) InvocationStatus(#Status)
* If not OK status, get the error message
If (*Not #Status.OK)
#Fld_Message := #Status.ErrorMessage
Endif
Endroutine
Create a webpage to invoke your server module:
Evtroutine Handling(#Com_owner.Initialize)
Define_Com Class(#TestFileServicesModule.TestFileCopy) Name(#FileCopy)
Define_Com Class(#PRIM_DC.UnicodeString) Name(#Message)
* Invoke the copy service via the server routine
* Adjust the source & target file paths
#FileCopy.Execute SourcePath('/home/tony/a.txt') TargetPath('/home/tony/b.txt') Message(#Message)
* Check if the server routine returns any error message
If (#Message.CurChars > 0)
#SYS_WEB.Alert( #Message )
Else
#SYS_WEB.Alert( 'All good!' )
Endif
Endroutine
