5) Run client.axis.sh to generate client stubs
In the previous step, you saw that the WSDL file describes the Amazon web service. The WSDL describes every single type of query you can make against the Amazon web service. These queries include a book search (AsinSearch), a WishList search, a Keyword search, and many others. The WSDL also describes all the search parameters and all the fields that are present in its response.
The key to writing a Java Amazon web service client is to produce Java code to set the parameters, initiate the search, and then read the fields in the response. Axis provides a way to generate all of this "boilerplate" code for all of Amazon's search query types directly from the WSDL file.
Open the client.axis.sh or client.axis.bat file. This file contains this one important line:
java org.apache.axis.wsdl.WSDL2Java -v -p com.amazon.soap.axis AmazonWebServices.wsdl
In either DOS or Cygwin, you can type in the above line and Axis' WSDL2Java program will generate all the "boilerplate" code. This is what will happen when you type in this line:
% java org.apache.axis.wsdl.WSDL2Java -v -p com.amazon.soap.axis AmazonWebServices.wsdl Parsing XML file: AmazonWebServices.wsdl Generating com\amazon\soap\axis\ExchangeRequest.java Generating com\amazon\soap\axis\AsinRequest.java Generating com\amazon\soap\axis\OrderItem.java ... lots of output omitted ... Generating com\amazon\soap\axis\AmazonSearchServiceLocator.java Generating com\amazon\soap\axis\AmazonSearchPort.java Generating com\amazon\soap\axis\AmazonSearchBindingStub.java
The key thing to realize is that the WSDL2Java from Axis will generate files in the directory tree com/amazon/soap/axis:
% ls -R com com: amazon/ com/amazon: soap/ com/amazon/soap: axis/ com/amazon/soap/axis: ActorRequest.java MarketplaceRequest.java AddItem.java MarketplaceSearch.java AddShoppingCartItemsRequest.java MarketplaceSearchDetails.java AmazonSearchBindingStub.java ModifyShoppingCartItemsRequest.java AmazonSearchPort.java OrderItem.java AmazonSearchService.java PowerRequest.java AmazonSearchServiceLocator.java Price.java ArtistRequest.java ProductInfo.java AsinRequest.java ProductLine.java AuthorRequest.java RemoveShoppingCartItemsRequest.java BlendedRequest.java Reviews.java BrowseNode.java SellerFeedback.java BrowseNodeRequest.java SellerProfile.java ClearShoppingCartRequest.java SellerProfileDetails.java CustomerReview.java SellerProfileRequest.java Details.java SellerRequest.java DirectorRequest.java SellerSearch.java ExchangeRequest.java SellerSearchDetails.java FeaturedProduct.java ShoppingCart.java Feedback.java ShortSummary.java GetShoppingCartRequest.java SimilarityRequest.java GetTransactionDetailsRequest.java SkuRequest.java GetTransactionDetailsResponse.java TextStreamRequest.java Item.java ThirdPartyProductDetails.java ItemQuantity.java ThirdPartyProductInfo.java KeyPhrase.java Track.java KeywordRequest.java UpcRequest.java ListManiaRequest.java Variation.java ListingProductDetails.java WishlistRequest.java ListingProductInfo.java _package.java ManufacturerRequest.java
These files will be used by the code in the JavaSampleCode directory.
