Re: accessing services at xmethods.net
A lot of the services at xmethods are non-standard or don't work. Assuming
you pick one that works properly, you should be able to take the WSDL and
generate a stub to talk to it. Most other SOAP toolkits work the same way,
although some use a call interface instead of a stub interface.

Re: accessing services at xmethods.net

For the most part Axis will generate valid WSDL, but as you can tell from
the discussion list, bugs exist, and sometimes the generated WSDL is not
valid. Sometimes it's just very difficult to generate good WSDLs from
complex object structures --especially if you aren't using beans or if you
are using Collection classes. That's why it's always a good idea to adopt a
WSDL-first development methodology. Many people will use java2wsdl to
generate a first pass at a WSDL definition, but you should always validate
it and verify that the generated WSDL does what you want. You may need to
tweak it to make it validate properly. From that point on, you should use
your validated WSDL as the primary source for the rest of your project --
i.e., generate your code from the WSDL, not the other way around. The same
holds true for other toolkits.
As for the xmethods.org directory -- many of those services have been there
for a long time, and they were developed either by hand or using very old
toolkits, and they simply have errors. In the early years (2000-2003), many
toolkits generated invalid WSDLs.

Thanks you so much for the hint !
But if you are using a web service toolkit that implements WSDL standard - the WSDL get generated should be valid WSDL (Axis for example uses ?wsdl at the end of the URL)
Are you meaning the WSDLs listed at xmethods.net are hand coded by service provider instead of generated by web services tool kits?
-OR- any other things makes the WSDL an invalid WSDL?
Thanks again

xmethods doesn't provide a toolkit -- it just provides a place for people to post their services -- it's up to the folks that post their service to make sure that they are valid. Many are not.
If the WSDL isn't valid, wsdl2java is likely to barf on it.

WSDL should be universal + language independent right?
are you meaning the SOAP toolkit xmethod.net services using didn't implement the WSDL standard, so when I use WSDL2Java to generate my client won't compatible with others?

xmethods doesn't provide a toolkit -- it just provides a place for people to
post their services -- it's up to the folks that post their service to make
sure that they are valid. Many are not.
If the WSDL isn't valid, wsdl2java is likely to barf on it.

Thank you so much anne, but could you explain what is non-standard?
WSDL should be universal + language independent right?
are you meaning the SOAP toolkit xmethod.net services using didn't implement the WSDL standard, so when I use WSDL2Java to generate my client won't compatible with others?
thanks again
