Problem with Model import through exsiting webservice

i created one converter webservice and deployed on sap j2ee engine,tested successfully.

after that i am trying to import the existing webservice as model class in to my webdynpro.

but it is saying invalid WSDL or no WSDL exits.

below one is my webservice

http://INLD50043555:50000/converter/Config1?wsdl

finally i able to import the webservice with small modification on the above url that is replaced <b>INLD5004355</b> with <b>localhost</b>.

my doubt is why it is not recognising the system name.

if webservice is on remote machine what is the case?

can any one give me the explanation to this?

thanks in advance
