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
"üåäöÜÅÄÖÂ" (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: "üÃ¥äöÃÅÃâ¦ÃâÃâÂ".
Strange.
This is the produced wsdl:

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>>üåäöÜÅÄÖ<</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>>üÃ¥äöÃÅÃâ¦ÃâÃâÂ<</item>
|
<item>>üÃ¥äöÃÅÃâ¦ÃâÃâÂ<</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 "üåäöÃÃ
ÃÃ" or
"üåäöÜÅÄÖ" whatever version looks
best.
I wont even try to fix the TEST2-response.
Regards,
Anders
