Can not deserialize instance of java.lang.Long out of START_OBJECT token

[Rodrigo Vega]

Hi,

i'm trying to a expose a method like this:

boolean isSomeConditionTrue(Long value)

And i'm making this call:

localhost/services/json?json={"method":"isSomeConditionTrue","params":
["long 1312100258"]}

i took this example from other post. However i can't make it work, I
always get the error:

Any clue?

[Wes Widner]

It looks like you're attempting to call a method that expects a Long with a
String. Try calling it with:

localhost/services/json?json={"method":"isSomeConditionTrue","params":

[1312100258]}

-Wes

[Rodrigo Vega]

Looks razonable. I will try it and let you know.

[Rodrigo Vega]

No look...
i tried:

localhost/services/json?json={"method":"isSomeConditionTrue","params":
[1312100258]}

localhost/services/json?json={"method":"isSomeConditionTrue","params":
1312100258}

localhost/services/json?json={"method":"isSomeConditionTrue","params":

{notused:1312100258}}

however i always get the same error:

org.codehaus.jackson.map.JsonMappingException: Can not deserialize
instance of java.lang.Long out of START_OBJECT token
