Question

I have a case: make work with forum by API fo Forum Engine IP.Board.

So i wrote next code:

package ru.test;

import java.net.MalformedURLException;
import java.net.URL;

import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;

public class mainClass {

    /**
     * @param args
     */
    public static void main(String[] args) {
        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
        try {
            config.setServerURL(new URL("http://hbf.by/interface/board/index.php"));
            XmlRpcClient client = new XmlRpcClient();
            client.setConfig(config);
            Object[] params = new Object[]{"74600b7376c4b1db69eaf8f155f2d157", "ipb","','"};

            Object result = client.execute("fetchOnlineUsers", params);
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XmlRpcException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

But i get exception

org.apache.xmlrpc.XmlRpcException: IP.Board could not locate an API module called ''

What’s wrong?

In Documentation (http://community.invisionpower.com/resources/documentation/index.html/_/developer-resources/miscellaneous-articles/xml-rpc-api-r246) sayed:

You should submit XML-RPC calls to the interface/board/index.php file.
You should send all parameters as a struct.

Every request must submit two parameters: api_key – this should be
the key set up earlier. api_module – this should be “ipb”.
Theoretically, you can create other modules, but “ipb” is all that
ships with IP.Board.

Where i make mistake.

And also how i can get methods.php file?

I write URL http://hbf.by/interface/board/modules/ipb/methods.php

But get blank page.

But also in Documentation sayed:

Open the interface/board/modules/ipb/methods.php file to see which
parameters each method expects to receive and will send back in
response

May be some server need configurations, but in internet i can’t find it.

Answer 1

Your code does seem to match the documentation.

But, XMLRPC often specifies the module in the call like this

Object result = client.execute("ipb.fetchOnlineUsers", params);

You could try that.
