Hi Luca,
you can replace on the wsdl of the web service the soap address with a variable, i.e.
<soap:address location="http://${pippo-ws}/
the variable is defined as
pippo-ws=localhost:9090 in an external file
for how to load parameters from an external file you must put this lines on your RTXConfig.properties
#export del file di properties
externalPropertyDirectoryJVMArg=namePathConfig
externalPropertyFileName=name.properties
then you must add this option on your catalina.bat
set CATALINA_OPTS= -DnomePathConfig=C:\anyPath§YouWant
i hope this will be useful
bye
Renato
