ERROR #6242 SOAP UNBOUND ADAPTER : Can't contact the web service ( HTTP error 301 )

Hi everyone.

I'm using a Buisness operation which have a SOAP outbound Adapter : 

We receive a HL7 message as the Request.. we parse it and we send a request to an API ( SOAP )

I imported my classes with the tools : 

I write some code for that, for the moment its just hard coded : 

I receive an error with HTTP error code 301 : 

I searched a lot on google but i didnt find any topic about that.

Can someone heal pon this one please ? 

Thank you 

Vessiere Thomas.
