Can't execute query on geocoding service

I'm building Flex 3 application and I have a geocoding service (http://.../GeocodeServer) on a ArcGIS server (ESRI). I'm trying to execute a query on this service in order to retrieve some

informations.

Unfortunately, when I execute the query, I get this error : [RPC Fault faultString="" faultCode="400" faultDetail="Inva开发者_JAVA百科lid URL"]

It's definitely not the URL that is invalid since my locator uses it without any problem. What could possibly the cause of this?

Thank you.

Have you tried executing against the URL using something like CURL or even in your browser. Please make sure those work first.

Simple answer after all.

Esri GeoCoding services aren't able to answer queries.
