What is the benefit of using Java SDK
eBay JAVA SDK is built on SOAP and provides features and functions that you would have to build:
1. ApiCall, ApiContext, ApiLogging and CallRetry classes that included in the SDK Core module provide significant convenience for making API call. It allows you to create an instance of the ApiContext class to hold your developer keys, token and retry/logging settings and to use ApiCall instance to actually execute the API request.
2. SDK exception module built in the SDK enables developers creating a robust and efficient application with minimum exception handling yet decent error signaling.
3. The Ant build file, sdkCodeGen.xml, bundled with the JAVA SDK makes the updating with eBay WSDL much easier.
4. The JAVA SDK is thread safe for multithreaded applications.
