help - problem with "Holiday" tutorial

[sairndain]

Hi

I am new to Spring WS and am having trouble with the "Holiday" tutorial.


PROBLEM:
When I run "mvn clean dependency:copy-dependencies package", it shows the example fails to compile!...

Is anyone familiar with the Spring WS "Holiday" example??
(e.g., "http://static.springframework.org/spring-ws/site/reference/html/tutorial.html#tutorial-creating-project")
-- Is the "HumanResourceService" class cited in the compile error message (below) a generated class?... Or, is it to be found elsewhere?... Or, am I supposed to created it (If so, I don't know what its supposed to contain)


The following exception stack is generated (this is a portion)

I think that is not the only problem with the code. You're also missing the bean definition for holidayEndpoint in spring-ws-servlet.xml.

The holiday example contains 2 packages: com.mycompany.hr.ws, where the endpoint implementation lays and com.mycompany.hr.service, where the class & interface actually doing the booking lay. Your directory structure should look like (sorry for the ascii art) :

+com
  +mycompany
      +hr
           +service
                HumanResourceService.java (this is an interface)
                StubHumanResourceService.java (this is the interface implementation
           +ws
                HolidayEndpoint.java

These should be in the sample code which is downloadable from the spring site. Basically the interface defines one method "bookService(Date, Date)" and the class logs something whenever the method is called. You can see that in HolidayEndpoint.java this is being called in the method invokeInternal().

You can download the tutorial examples from the spring website, go to download and then just make sure you get the "spring-ws-with-dependencies.zip" file.

If you just use that (you'll find it under samples/tutorial), all should be ok and there are several more examples to see, some that don't require parsing XML at all (the airline example).
