Use the Java Wrapper to generate a Java server interface object. See Generating a Java Server Interface Object. Write your Java server and proceed as described under Generating a Java Server Interface Object.
Build an EntireX RPC client using any EntireX wrapper. See EntireX Wrappers. For a quick test you can:
use the IDL Tester; see EntireX IDL Tester in the Designer documentation
generate an XML mapping file (XMM) and use the XML Tester for verification; see EntireX XML Tester in the XML/SOAP Wrapper documentation
