Hello everyone, I’m new to EntireX and I need some help. I have to make a RPC to a remote system and the only thing I know is the IP, the port and some other stuff about the methods I can invoke (names, params, etc). So my question is, how can I make a simple client? Note that I don’t have any API / JARs from Software AG. Can I invoke with Java RMI / CORBA or something like that? What do I have to know about the server for my client? I searched through the Demo Zone and I found only the client generating stuff with the IDL (!?) file and with the EntireX Eclipse which I don’t want to use. Is there any alternative? Thanks in advance! ---

Kevin, you will need the EntireX runtime jar, there is no way around that, because it implements the protocol to talk to the RPC server. Best regards, Wolfgang ---

Thank you for the quick answer. Is this free to download or do I have to send a request for it? Is the server hosting company allowed to send me the jar? Or (which would be the worst) do I have to pay for it? ---

What protocol do you want to use to talk to your remote system? ---

Is the EntireX runtime jar free of charge or is it licensed ? TIA Andrzej ---
