Since XML-RPC is already built into Zope, you do not need to work about that. You need however to write a java client to access your ZOPE method. There is information and a JAVA client on the xml-rpc site http://www.xmlrpc.com/. You can find enough info to start with. Philip

I'm planning on using Zope as some middleware to an SQL database backend. Zope will implement the per-row ACL checking and such for the database application, and there are two clients - a simple web-based Zope frontend, and a larger standalone Java application. I'd like the Java app to communicate with Zope using XMLRPC, so that I can re-use the middleware portion, and take advantage of SSL'd HTTP, along with all the other bonuses such as not trusting the client :o)

But: I'm having problems that indicate I don't understand how External Methods or the XMLRPC call support works.

I have an SQL query method backed by a persistent DB connection. I want to call that method over XMLRPC remotely. How do I do that? Namely, how do I pass named arguments to the SQL method?

Also, I did some simple External Method examples, and acquisition doesn't seem to work as advertised: This:

def testf(self, REQUEST): return self.index_html()

Gives an error "standard_html_header not found". What's going on?

Regards, Phil
