create a REST connection to a server in Java

I need the connection to the REST API defined at [login to view URL] implemented. I created 15 unit tests to check the connection works with the life server. These tests are the milestones: 1: canGetPriceDataWithDepth 2: canLoginWithoutException, canGetAssets 3: canCancelAllOrdersWithoutRaisingExceptions 4: canSendBuyOrderAndCancelItWithoutRaisingExceptions 5: canSendSellOrderAndCancelItWithoutRaisingExceptions 6: canSendOrdersAndCancelThem 7: toIdentifyOrdersTheExternallyGivenUniqueOrderIdMustBeUsedInDriver 8: whenOrdersWereSent_getOpenOrderMap_returnsAllReceiptsNotInEndState, whenOrdersWereSent_getAllOrderMap_returnsAllReceiptsNotYetClearedFromDriver, whenOrdersWereSent_getReceipt_returnsAlsoReceiptsInEndstate, whenOrdersWereCanceled_clearReceipt_deletesOrderFromCache 9: whenOrdersWereSent_cancelAllOrders_cancelsThemAll 10: noStaticMethodsExceptInFactoriesAndTests, noMethodsThrowingCheckedExceptions You find the tests in [login to view URL] [login to view URL] [login to view URL] The implementation has to be done in package [login to view URL] A ZIP with the project is available as attachment. Each of the milestones is worth 10% of the total pay. Please set up 10 milestones. I will release payment for each passing and reviewed group of tests.
