I'm getting a NoSuchMethodError exception in my application. But where is the "L" getting appended infront of "com/test/.."

Question

Execution exception NoSuchMethodError occured : com.test.refFilesDataService.service.RefFilesDataServiceDelegate.fetchSegmentation(Lcom/test/refFilesDataService/service/RefFilesDataServiceSegmentationRequest;)Lcom/test/refFilesDataService/service/RefFilesDataServiceSegmentationResponse;

Calling using the following line:

RefFilesDataServiceSegmentationResponse response = getService() .fetchSegmentation(request);

This is a newly added method to the external jar I'm referring to. All other methods in the jar works without a problem except this. Works in my local but fails in the Dev environment

Answer 1

Try

javap -classpath yourexternal.jar com.test.refFilesDataService.service.RefFilesDataServiceDelegate

on your test & dev environment and compare the method & signatures.
