I am writing a servlet in which I call Amazon web service. Here is
what I did:
1. Used Amazon tools and compiled their classes to a jar file called
azwsdl.jar.
2. Used JBuilder to construct a servlet.
3. Added azwsdl.jar as a required library.
4. In my doGet method, put something like:
com.amazon.soap.axis.AmazonSearchService service = new
com.amazon.soap.axis.AmazonSearchServiceLocator();
However, the servlet crushed at the the statement above.
Could anyone help?
Thanks,
Here is the print-out:
