OTA? Do you mean "open travel alliance" or "over the air"? (HINT: never use abbreviations that are not very well known; when in doubt, spell things out)
Perhaps if you described what it is you are trying to accomplish it would help.
i meant Open Travel Alliance, i have to send Data about an hotel reservation to Travel Fusion (a Global Destribution Service), in order to get a list of available Hotels, i tried to follow the tutorial of sourceforge that uses JiBX but it wasn't clear also i think that the joinded codes contain some errors besides i must use JAXB
To be more clear, i want to connect to Travel Fusion web services via OTA RQ and RS
