Just looked at the NewbieTrails.  So are you looking for volunteers to work
on the following:

Requested Trails

 * UsingCommandLineTools?
 * GettingStartedWithAttachments?
 * BestPracticeForCreatingServices?

 If so, is there are certain approach to supplying the requested information?
 Anotherwords, if I submit something is there any type of editing process
- specifically to ensure everything is technically correct?

Web services are difficult...

The wiki at is
helpful, but there isn't enough detail, or I just am not experienced
enough with XML to understand.

Does anyone any a recommended step-by-step approach to learning how to
write _GREAT_ Web services?

For example, what are the appropriate places to use Web services?

I have seen a lot of messages about sending attachments up to the
server, but that is not how I thought a Web service would be used.  I
was thinking about an example: I send a invoice number to a getInvoice()
web service that returns a PDF file.  Is this appropriate for a Web
service.  It is providing a valued service after all.  But then, how in
the world would you program this?  Heck, I'd love to see a mocked up
example that returns any pdf file in a directory just to see it work.
Would the client need axis?  Could this be accessed with a URL -
something like
Would the PDF then render in the browser?

I would like to see a book (Idiot's guide or something) that had real
examples (working examples):

RPC - Send two numbers, get the result back (easy)
RPC - Send text, get a pdf back of the text as an attachment (hard)
Wrapped seems so close to RPC, that I would include an example of these
with the modified .wsdd file.  Maybe I am wrong, but that is the only
difference I could find.

Message services - What a can of worms this has been.  I have worked for
weeks to get something working (unfortunately, lots of unanswered posts
- how do you ask questions that get answered?).  This is an area that I
have seen very few working examples.  The echoMessage Web service really
didn't help me.  I would love to see a simple example using third type
of Message style using documents.

I found the book "Professional XML Development with Apache Tools" by
Leung to be helpful and also complicated.  Are there other good books
out there that are current.  I keep waiting for the Apache Axis book
from O'Reilly to get published.  It has a publish date of last March,
but I haven't seen it available yet.

If I ever get to understand this stuff, I wouldn't mind writing a guide
myself - sure, I volunteer, but first I need to learn it!

Thanks for listening,

Ken Lee
