hi all follwing is the sample code written using dbus, where there is one server which has got method ManyArgs which i want to invoke from client. Following is the code snippet, MyServer.xml <?xml version="1.0" encoding="UTF-8" ?> <node name="/com/example/MyServer">   <interface name="com.example.MyServer">     <annotation name="org.freedesktop.DBus.GLib.CSymbol" value="my_server"/>     <method name="ManyArgs">              <annotation name="org.freedesktop.DBus.GLib.CSymbol" value="my_server_many_args"/>     </method>   </interface> </node> MyServer.c #include <stdio.h> #include <glib-object.h> #include <glib/gi18n.h> #include <dbus/dbus-glib.h> #include "server.h" static gboolean my_server_many_args() {     if(1)     {         printf("\nmy_server_many_args\n");              return TRUE;            }     return FALSE; } #include "my-server-glue.h" static GMainLoop *loop; DBusGConnection *connection; static MyServer *server; G_DEFINE_TYPE(MyServer, my_server, G_TYPE_OBJECT); /* Class init */ static void my_server_class_init (MyServerClass *my_server_class) {   //g_type_class_add_private (e_data_book_factory_class, sizeof (EDataBookFactoryPrivate));   printf("\ni am class init\n");   dbus_g_object_type_install_info (G_TYPE_FROM_CLASS (my_server_class), &dbus_glib__object_info); } /* Instance init */ static void my_server_init (MyServer *server) { } int main (int argc, char **argv) {   GError *error = NULL;   guint32 request_name_ret;   g_type_init ();   loop = g_main_loop_new (NULL, FALSE);   /* Obtain a connection to the session bus */   connection = dbus_g_bus_get (DBUS_BUS_SESSION, &error);   if (connection == NULL)   {       printf("\nFailed to open connection to bus\n");   }      server = g_object_new (TYPE_MY_SERVER, NULL);   dbus_g_connection_register_g_object (connection,                                        "/com/example/MyServer",                                        G_OBJECT (server));   g_main_loop_run (loop);          dbus_g_connection_unref (connection);   return 0; } MyClient.c //#define DBUS_API_SUBJECT_TO_CHANGE #include <dbus-1.0/dbus/dbus.h> #include <dbus-1.0/dbus/dbus-glib.h> #include "my-server-bindings.h" int main (int argc, char **argv) {   DBusGConnection *connection;   DBusGProxy *proxy;      DBusMessage *message;      GError *error;   char **name_list;   char **name_list_ptr;   guint32 request_name_ret;   g_type_init ();   error = NULL;   connection = dbus_g_bus_get (DBUS_BUS_SESSION,                                &error);     if (connection == NULL)     {       g_printerr ("Failed to open connection to bus: %s\n",                   error->message);       g_error_free (error);       exit (1);     }   /* Create a proxy object for the "bus driver" (name "org.freedesktop.DBus") */     proxy = dbus_g_proxy_new_for_name (connection,                                      DBUS_SERVICE_DBUS,                                      "/com/example/MyServer",//DBUS_PATH_DBUS,                                      "com.example.MyServer");    // com_example_MyServer_many_args (DBusGProxy *proxy, GError **error)     if(!com_example_MyServer_many_args (proxy,&error))      //printf("i am failed");     {       /* Just do demonstrate remote exceptions versus regular GError */       if (error->domain == DBUS_GERROR && error->code == DBUS_GERROR_REMOTE_EXCEPTION)         g_printerr ("Caught remote method exception %s: %s",                 dbus_g_error_get_name (error),                 error->message);       else         g_printerr ("Error: %s\n", error->message);       g_error_free (error);       exit (1);     }   g_object_unref (proxy);   return 0; } Steps I do, I run first server program which according to me registers object to dbus (object which has method ManyArgs) Then I run client which establish connection with dbus and gives call to ManyArgs, Output I am getting is error: Error: org.freedesktop.DBus does not understand message ManyArgs Can anybody tell me what is wrong. Any Pointers on it will be helpful. <hr size=1></hr> Here’s a new way to find what you're looking for - <a href="http://us.rd.yahoo.com/mail/in/yanswers/*http://in.answers.yahoo.com/">Yahoo!
