Amazon seller MWS API and eBay API import to filemaker

Hi Guys, Goal: I want to automatically import information from my amazon Seller account using amazon MWS API (import to filemaker) and use this information to update my seller account in ebay using ebay API I started doing it but I am not good in Java and would like someone to help me - you don't need to know anything about filemaker - within filemaker there is a plugin called scriptmaster that uses groovy and java language - It seems pretty trivial - Amazon has a clear documentation with Java library and example on how to use it - when I search the web it seems like everyone can use the amazon sample code out of the box but I tried to use eclipse and I am not sure what I am doing wrong - same goes for ebay portion What I need: Well, I need a java code where I can input my amazon developper credential and the result should be all my non-amazon order information ( in the regular xml format) - then I need a second java code that will allow me to POST in my ebay API to update the tracking number info that I got from amazon you will not write anything from scratch all the codes are in the web - I just dont know how to use them - I dont know java - Thanks
