XmlRpc.parse problems
Hello. I am getting a java.lang.NumberFormatException when calling execute
on my client with specific parameters (the stack trace and debug output is
below). I am trying to call execute with 5 parameters. Each of them is a
string, but for some reason the parser is trying to convert the two date
strings to integers. I need them to be strings and not integers or the
date type, in order for the xml-rpc server to process the call. Here is
the call (from debug output).
Client calling procedure 'PIPES.NetworkMeasurement' with parameters [V4,
STTL, DNVR, 20031102000000, 20031103000000]
Anyone have any idea how I can force it to not convert the date strings to
integers?
Stack Trace and Debug:

Hmm. No, its the same code. I even deleted the class files and recompiled
to make sure and also tried toggling debug output on and off. So I am sure
its the same code.
Actually, could this be an error in the response instead of the request?
Thats probably why it says "startElement: methodResponse"... heh. Ok, if
so, I'll have to contact the person who wrote the server to get it sorted
out I guess. Darn, sorry for the trouble.
Thanks,
Tanya

The code you post looks fine. However it does not correspond to the parse
trace you posted. Is it possible that you are not running the code you
posted?

I'm using the org.apache.xmlrpc.XmlRpcClient. Here is the code I have to
create the client (changed a bit for privacy):
client = new
XmlRpcClient("http://someurl.org/xmlrpc_server.cgi");
Vector xmlrpcParams = new Vector();
xmlrpcParams.add("V4");
xmlrpcParams.add("STTL");
xmlrpcParams.add("DNVR");
xmlrpcParams.add("20031102000000");
xmlrpcParams.add("20031103000000");
Vector results = (Vector) client.execute("PIPES.NetworkMeasurement",
xmlrpcParams);

I guess thats what I thought I was doing by adding them to the execute
vector parameter as strings.

What XML-RPC client are you using? It is sending the "date" values as
<int>s. It's also sending the first parameter as a <struct> with the first
member being another <struct> with the "data" as the first member of the
inner <struct>.
You would be better off sending your "date" values as <string>s if you want
to use this format.
