Error related to decimal format when spring application try make a payment with PayPal -

In my current spring project, I recently added support to PayPal. But right now, the payment has only been exhausted when I have tightened the values ​​of the amount in the source code. The methods that handle the payment process in my service category mount the variable where this value is stored in this way:

  decimalf df = new substitute ("0.00"); Float value = hero (client); String svalue = df.format (value) .replace (',', '.'); System.out.println ("valor =" + value); System.out.println ("hero (string) =" + tailoring); Description Details = New Description (); Details.setShipping ("0"); Details .Setbottle (Silv); Details.setTax ("0"); Zodiac = new amount (); Amount.setCurrency ("BRL"); Zodiac. Settool (silva); Amount.setDetails (description); Transaction Transactions = New Transactions (); Transaction.setAmount (amount); Transaction.setDescription (select "No Site Loose On Line");  

When I run the application and try to pay, I get this error:

  Depth: Error code: with 400 responses : {"Name": "VALIDATION_ERROR", "details": [{"field": "transaction [0]. Monetary digit", "issue": "The amount of currency should be a non-negative number, alternatively alternative form From two decimal places to '' ', optional thousands separators',', decimal digits "}, {" field ":" transaction [0] .mount.details.subtotal "," issue " The first is limited to 7 digits: "limited to 7 digits prior to" currency amount non-negative number, alternatively decimal point "}", alternate thousands separator ',' alternatively by two decimal places alternatively Can be included: "Invalid request - view details", "notification_link": "http://ttg.developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR", "debug_id": "9639791c47625"} < / Code> 

Can anyone tell me what I am remembering here? I think that decimalf df = new To use Dsmlvfl ( "0.00"); The total value should be enough to format my subtotals, but apparently I am doing something wrong.

It looks like when you pass the "code" in the zodiac sign in the svalue. ; " String type

I will advise you to do this:

  Amount .Setallol (float .Parflat (Silv));  

and also here:

details.setSubtotal (svalue); to details.setSubtotal (Float.parseFloat (svalue));
