Sorry for my mistake, i actually return the correct variable, i only copy wrong code here... and is numeric key, and i'd like to be like that.

In LuaJava, the LuaState object has the same methods that is in C. If you know how to do is in C, i think we can do it with LuaState in java.
I try replace in lua script the line "t[03] = "3"" for "t["03"] = "3"" and really work, i get the number "3" (the value of key "03"), but i'd like to use numeric keys.

Thanks for reply.

What java API/bindings are you using to access Lua?

Those are numeric keys.
That table will contain:
{
[3] = "3",
[11] = "19",
[12] = "25"
}

Also the return is using the wrong variable name.

Here you are trying to get a string key "03" from a table that only has
numeric keys. I don't know what Java API you are using to access Lua, but
there should be a way to get numeric keys from the table.
