I am using Java Communications API. Want to know that is it compulsory to set CSCA (Service Center Address) using the AT command: AT+CSCA= for sending sms through java application? Or we can just skip that part and send the AT Command AT+CMGS= to send the message? Any help would be appreciated. Thanks!

Presumably your sending via a hardware device with a SIM card; that card will most likely come configured with a profile that specifies the home networks service centre number – after all you don’t have to enter one yourself when you acquire a SIM for your own phone.
You can test for one with
+CSCA?.
