Re: [jetty-users] Embedded Jetty: Failed to locate resource XmlRpcServle

["Georg M. Sorst" <georgsorst@xxxxxx>]

Hi David,

thanks for your pointers, just what I was looking for.

It seems the XmlRpcServlet.properties was located in the wrong 
directory. It is loaded via .getResource(...), and from what I have read 
the rule is:

  * files in src/main/webapp/WEB-INF/classes are loaded with 
getServletContext().getResource()
  * files in src/main/resources are loaded with getClass().getResource()

At any rate, I moved the file to src/main/resources and everything works 
fine. Just for the record, is this the correct location?

Also weird: before I moved it the file wasn't even copied to the target/ 
directory, unless I explicitly added src/main/webapp/WEB-INF/classes to 
the list of source folders in Eclipse. Is this excepted? Just curious, 
this is a whole different topic :)


Thanks again, David, and best regards,
Georg
