IMO, something like [icode]client.execute("System.listMethods", new ArrayList())[/icode] or [icode]client.execute("system.listMethods", new ArrayList())[/icode] should do the trick. Re: Need some help interacting with an XML-RPC server 14 Years Ago by leiger I definitely looked at the official website, but I don't remember seeing that particular page. I think those instructions might be out of date though. For one thing it suggests: [CODE]import org.apache.xmlrpc.client.XmlRpcClient;[/CODE] That couldn't be found on my machine. I checked the Jar file and found that it wasn't in a subfolder called … Re: Need some help interacting with an XML-RPC server 14 Years Ago by ~s.o.s~ To find out which JAR a given class belongs to, use a service like GrepCode. It tells you all the possible JAR files which has that particular class along with providing download for the same. For e.g. here's the [URL="http://grepcode.com/snapshot/repo1.maven.org/maven2/org.apache.xmlrpc/xmlrpc-client/3.1.3/"]grepcode result[/URL] for the… Re: Need some help interacting with an XML-RPC server 14 Years Ago by leiger I was able to get system.listMethods working eventually. Turned out that the latest version of Apache XML-RPC only had [I]some[/I] of the JARs I needed... for some strange reason. Had to search through Google for the rest. Now I'm having more problems - any method that requires a parameter doesn't work :S (I can't seem to figure out what data type… Re: Need some help interacting with an XML-RPC server 14 Years Ago by ~s.o.s~ What do you mean by "doesn't work"? Exception? No result? Anyways, have you tried passing in an Object array as shown in the official documentation? Paste the code you are using. Re: Need some help interacting with an XML-RPC server 14 Years Ago by leiger As I mentioned, "I can't seem to figure out what data type to pass in!". What I mean by that is that I am getting an XmlRpcException with the message "Calling parameters do not match signature". [CODE] CLASS: class org.apache.xmlrpc.XmlRpcException MESSAGE: Calling parameters do not match signature [/CODE] Passing in an empty … Re: Need some help interacting with an XML-RPC server 14 Years Ago by leiger Solved the problem. The Apache XML-RPC libraries only accepted a List and Object[] ... so I was trying to explicitly cast to Object[] instead, and was getting problems with that. This worked (passing in a Hashtable, inserted into an Object[]), as it is passing in an Object[] array as the parameter... and the method accepted it: [CODE=Java] // … Re: Need some help interacting with an XML-RPC server 14 Years Ago by ~s.o.s~ > Solved the problem Good thing that you could come up with a solution on your own. A couple of points though in case you are starting with Java: [LIST] [*] Declare/define variables closest to their usage point. In your code, you create an object array on the first line and use it on the 4th line. The lesser the scope of your variables … Re: Need some help interacting with an XML-RPC server 14 Years Ago by leiger I've taken your suggestions on board and have modified my code as you suggested. [I][B]>[/B] A thousand declarations at the start of a method add to the confusion.[/I] Usually, I would compact my code as much as possible when I'm writing it (with the exception that I dislike using the shortened form of an if statement). As anything networking… Re: Socket programming ansic server to java client 13 Years Ago by NormR1 The readLine() method is for reading lines. A line ends with an line end character. The readLine method will continue reading until it gets a lineend. Some solutions: Use the read method and read the data into an array as it comes or have the sender add line end characters Re: Socket programming ansic server to java client 13 Years Ago by Jnk Thanks! Adding the endline did the trick.
