I hava a pmml file which is generated by Knime, I deployed it to sever and I can get its info from server,such as

 curl http://localhost:8080/openscoring/model/dtclf
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

      "dataType" : "integer",
      "opType" : "continuous",
      "values" : [ "[0.0, 51.0]" ]
    }, {
.......

but when I post a json to evaluate, it returned a error:

$ curl -X POST --data-binary @query.json -H "Content-type: application/json" http://localhost:8080/openscoring/model/dtclf
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

  "message" : "For input string: \"3.5\""
}

I tried to use python client, and got the same error.

The error traceback info on the server is

java.lang.NumberFormatException: For input string: "3.5"

You cannot parse a String value of "3.5" to an integer (java.lang.Integer or java.lang.Long) value without loss of precision. In other words, what would happen to the fraction of "0.5"?

The KNIME software is generating invalid PMML documents when there are integer fields involved (both as inputs or outputs). Please open an issue request with the KNIME software instead.

Really thanks a lot, I solved the problem by changing "Integer" to "Double" in the pmml file.
