[jboss-user] [JBossWS] - Web Service Response encoding problem

[AndersM]

Hi,
I'm having problem with the encoding of java.lang.String in my Web Service response.
Seems like a String in a complex data structure will be returned as ISO-8859-1 instead of UTF-8. 
If the WebMethod only returns a String it will be interpreted correctly as UTF-8. Very odd.

I've written a small example made up of one interface:

package se.test.webservice.bean;
  | 
  | @javax.jws.WebService
  | @javax.jws.soap.SOAPBinding(style = javax.jws.soap.SOAPBinding.Style.RPC)
  | public interface Text extends java.rmi.Remote {
  | 	@javax.jws.WebMethod(operationName = "TEST1")
  | 	String test1(@javax.jws.WebParam(name = "Text1")
  | 	String x);
  | 
  | 	@javax.jws.WebMethod(operationName = "TEST2")
  | 	String[] test2(@javax.jws.WebParam(name = "Text2")
  | 	String x);
  | }
and a stateless session bean:
package se.test.webservice.bean;
  | 
  | @javax.ejb.Stateless
  | @javax.jws.WebService(endpointInterface = "se.test.webservice.bean.Text")
  | public class TextBean {
  | 	public String test1(String x) {
  | 		return ">" + x + "<";
  | 	}
  | 
  | 	public String[] test2(String x) {
  | 		String[] returnValue = {">" + x + "<", ">" + x + "<"};
  | 		return returnValue;
  | 	}
  | }
The jar is deployed on JBoss AS 4.2.1.GA.
Calling method TEST1, I'm using the Web Service Explorer from within Eclipse, with a character string containing Swedish special characters "&uuml;&aring;&auml;&ouml;&Uuml;&Aring;&Auml;&Ouml;–" (I hope these will come out OK when I submit this post) the response looks fine. But calling method TEST2 with the same string will produce a response that looks like it is UTF-8 characters interpreted as ISO-8859-1: "üåäöÜÅÄ֓". Strange.

This is the produced wsdl:

  | 		</port>
  | 	</service>
  | </definitions>

This is the response from TEST1:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  | 	<env:Header />
  | 	<env:Body>
  | 		<ns0:TEST1Response
  | 			xmlns:ns0="http://bean.webservice.test.se/">
  | 			<return>>&uuml;&aring;&auml;&ouml;&Uuml;&Aring;&Auml;&Ouml;<</return>
  | 		</ns0:TEST1Response>
  | 	</env:Body>
  | </env:Envelope>

And the response from TEST2:

  | <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
  | 	<env:Header />
  | 	<env:Body>
  | 		<ns0:TEST2Response
  | 			xmlns:ns0="http://bean.webservice.test.se/">
  | 			<return>
  | 				<item>>üåäöÜÅÄ֓<</item>
  | 				<item>>üåäöÜÅÄ֓<</item>
  | 			</return>
  | 		</ns0:TEST2Response>
  | 	</env:Body>
  | </env:Envelope>

I hope someone can shed some light on the problem.

I looked at the preview and of course all the characters looked like crap.
I'll try to restore them above but if I fail the correct version of the characters should look like "üåäöÜÃ
ÄÖ" or "&uuml;&aring;&auml;&ouml;&Uuml;&Aring;&Auml;&Ouml;" whatever version looks best.
I wont even try to fix the TEST2-response.

 Anders
