Problem in serialization "scala.math.BigDecimal does not have a no-arg default constructor"
I'm new to scala programming and java so here is my problem:
I have an object to be serialized with a BigDecimal Property
import java.util.Date
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter
import reflect.BeanProperty
class TestObject {
@XmlJavaTypeAdapter(classOf[BigDecimalAdapter])
var test: BigDecimal = 0.00
}
I receive this error:
scala.math.BigDecimal does not have a no-arg default constructor
XmlAdapter:
import javax.xml.bind.annotation.adapters.XmlAdapter
class BigDecimalAdapter extends XmlAdapter[String, BigDecima开发者_StackOverflowl] {
def unmarshal(str: String) = BigDecimal(str)
def marshal(bD: BigDecimal) = bD.toString()
}
SOAPServer:
import javax.jws.soap.SOAPBinding
import javax.jws.{WebParam, WebMethod, WebService}
import javax.xml.ws.Endpoint
@WebService(targetNamespace="test", name="testws", portName="test", serviceName="wsTest")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
class Server {
@WebMethod(action = "test")
def test(@WebParam(name = "testParam") testParam:TestObject): TestObject = {
return testParam
}
}
object SoapServer { // defined Companion Object for our class
def main(args: Array[String]) { // main method to make this a runnable application
val endpoint = Endpoint.publish("http://192.168.189.132:8080/wsTest", new Server())
System.out.println("Binded to port 8080. Waiting for requests...")
}
}
I think you probably want to be using java.math.BigDecimal
, as opposed to scala.math.BigDecimal
. Use the fully-qualified path name:
import java.math.{BigDecimal => JDec}
var test: JDec = new JDec(0)
It seems like the jaxb framework is expecting a no-arg constructor; I'm not familiar enogh with it to understand why
