Answer 1

We didn't develop the Java API ourselves but it sounds like you're not passing a number for the amount field of the request but instead some kind of string.

Comments

However, the 'parameter' of 'sendtoaddress' in a multichain is defined as a string and a real number

---

That API, like many others, has more than one parameter. You need to pass a string (for the address) AND a number (for the amount).

umm...
If you look at my source code above, you'll see that 'address' is a string and 'amount' is a real number. What's the problem?

OK, sorry about that. We can't see anything immediately wrong with what you're doing, so it's worth contacting the creator of the Java library to see if he can help.
