getConfigurationHost() and getCompositeHost() are deprecated macros. Since introduction of the new component diagram with Builder 6.0, it is not possible anymore to specify a deployment in the xUML model and these macros will only return "localhost".

Syntax
getCompositeHost()
SemanticsReturns the name of the Bridge node instance the compiled xUML service was deployed to.
Examples
set host = getCompositeHost();
