Hi, In a previous mail, I was asking if anyone had issues with ZopeProfiler and Zope 2.8. I have made many more tests and my issue is completely unrelated with Zope 2.8 (I got the same issue with Zope 2.7.6) The issue has to deal with an XML-RPC call to a java service (using the standard xmlrpclib module). The code is (method of a class of my own): def query(self): from xmlrpclib import ServerProxy, loads, ProtocolError try: if self.protocol=='HTTP GET': self.result=loads(urlopen(self.url).read())[0][0] elif self.protocol=='XMLRPC': self.result=getattr(ServerProxy(self.url),self.rpc_method_expr)(*self.params ) except ProtocolError: self.result=None self.zeroconf_exception=1 self.log_exception() except SocketError: self.result=None self.zeroconf_exception=1 self.log_exception() except IOError: self.result=None self.zeroconf_exception=1 self.log_exception() except: self.result=None self.log_exception() This works fine with disabled profiler. However, when I enable the profiler, I get this error : Fault: <Fault 0: 'java.lang.Exception: RPC handler object "cat.getProducts" not found and no default handler registered\n\tat org.apache.xmlrpc.SelfDocumentingHandlerMapping.getHandler(Ljava.lang.String ;)Ljava.lang.Object;(Unknown Source)\n\tat org.apache.xmlrpc.XmlRpcWorker.execute(Ljava.io.InputStream;Lorg.apache.xmlr pc.XmlRpcContext;)[B(XmlRpcWorker.java:183)\n\tat org.apache.xmlrpc.DocXmlRpcServer.execute(Ljava.io.InputStream;Lorg.apache.x mlrpc.XmlRpcContext;)[B(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcServer.execute(Ljava.io.InputStream;Ljava.lang.St ring;Ljava.lang.String;)[B(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcWebServer$Connection.run()V(Unknown Source)\n\tat org.apache.xmlrpc.DocXmlRpcWebServer$Runner.run()V(Unknown Source)\n\tat java.lang.Thread.run()V(Optimized Method)\n\tat java.lang.Thread.startThreadFromVM(Ljava.lang.Thread;)V(Optimized Method)\n'> I can reproduce that error if I omit (*self.params) on that line : self.result=getattr(ServerProxy(self.url),self.rpc_method_expr)(*self.params ) But when I add some logging, self.params looks fine. Changing that line into : self.result=apply(getattr(ServerProxy(self.url),self.rpc_method_expr),self.p arams) Gives the same error. I also tried hardcoding the arguments, and I still get the same issue ! I don't know what to do, I really need to profile my Zope instance. So any suggestion would be highly appreciated... Thanks.
