Thanks for reply.

It is a compiler error

Thanks for reply.

Code snippet:

AmazonECS service = new AmazonECSQuery(accessKeyId, associateTag);
....
ItemLookupRequest request=new ItemLookupRequest();
....
ItemLookupResponse response = service.itemLookup(request);

Eclipse complains that

The method itemLookup(ItemLookupRequest...) in the type AmazonECS is
not applicable for the arguments (ItemLookupRequest)	Test/src/com/
amazon/webservices/test	AWSTest.java

Thanks,

What version of Java are you using?  Try compiling it, and paste the

Maybe your method is overloaded.

May you show the entire source?
