Eclipse java JAX-RPC web service import generates an interface instead of a class

Question

therefore, when trying to instantiate an object of the class, the error is

Cannot instantiate the type

Does anyone know why Eclipse would generate an interface instead of a class? The web service was originally written in VB.Net but can be replicated following the simple example given here

1. Start an eclipse project.
2. Add a new Web Service client http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

3. Write the code...

    package test; import NET.webserviceX.www.CurrencyConvertor; import NET.webserviceX.www.CurrencyConvertorSoap; import NET.webserviceX.www.Currency; public class Convert { public static void main(String[] args) { CurrencyConvertor cc = new CurrencyConvertor(); // Gets an implementation of the interface we can use // to contact the web service. CurrencyConvertorSoap ccs = cc.getCurrencyConvertorSoap(); // Send the SOAP request to the server and get the result from the web service double conversionRate = ccs.conversionRate(Currency.GBP, Currency.USD); System.out.println("£1 is worth $" + conversionRate ); } } 

What's happening is the CurrencyConverter.java is imported as an interface, so it can't be instantiated.

It should be imported as a class. Why isn't it?

Answer 1

I cannot reproduce your pb, but if you use java 1.6+ then you can generate your types with wsimport tool provided in JDK.

use following command in a terminal:

Windows:

"C:\Program Files\Java\jdk1.6.0_45\bin\wsimport.exe" -keep http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

Linux:

pathToJDK/bin/wsimport -keep http://www.webservicex.net/CurrencyConvertor.asmx?WSDL

You'll see some warnings, just ignore them. Then you'll get your class CurrencyConvertor.

I've tried this on my machine and it works!

I saw you're trying to us wscompile . In fact, this tool had been replaced by wsimport long time ago. see oracle documentation:

http://docs.oracle.com/cd/E17802_01/webservices/webservices/docs/2.0/jaxws/UsersGuide.html

Part 1.1.2 Fully Dynamic Runtime

It should also be noted that wscompile has been replaced by two new tools: wsimport and wsgen. wsimport is used for importing WSDLs and generating the portable artifacts.

Answer 2

Have to use wscompile from "java web services developer pack" which requires a JDK 5... and was designed for pre-win 7 OS.
