You can always recreate "statefulness" by using keys to access a list or map
of singleton data objects. Your server object would create/store init'd
values for use on subsequent calls:
client.execute("init", ["mykey",x,y,z]);
would be handled as:
// create new MyObj and associate it w/ "mykey" (if necessary)
MyObj o = MyObj.getInstance("mykey");
o.init(x,y,z)
and
client.execute("doSomething", ["mykey",b]);
would be:
// get existing MyObj associated w/ "mykey" (exception if doesn't exist)
MyObj o = MyObj.getInstance("mykey");
o.doSomething(b);
Of course you'd have to clean-up the map/list occasionally...but there are
several object pool implementations available for that type of situation.

Subject: Re: Accessing non-static methods
Thanks for the comments & discussion, but I still have the problem.
I tried tweaking the code such that I wasn't calling a method with null
arguments:
My Object is now of the form
MyObj o = new MyObj(x,y,z)
o.doSomething(Boolean b);
I've adapted this to:
client.execute("o.init", [x,y,z])
client.execute ("o.doSomething", [b])
but I'm still getting null errors; all the methods accept and return a
value (although they're ignored), so I suspect the null is due to the
"loss" of the object.
I wonder if this is to do with the "Statelessness" of XML-RPC - I
haven't read the code, but if it is stateless, then there's perhaps no
carry over between the two calls.
Can anyone give any advice on this?
Thanks,
Matt
