Subject [jira] Commented: (CXF-1771) WstxUnexpectedCharException when returning a String from a CXF SOAP service containing specific characters (used with CXF client)
Date Fri, 29 Aug 2008 15:42:44 GMT

    [ https://issues.apache.org/jira/browse/CXF-1771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627017#action_12627017
] 

Martijn Brinkers commented on CXF-1771:
---------------------------------------

True but my CXF soap service just returns a String. So does that mean that when you return
a String from your CXF soap service you (the one implementing the CXF service) must be sure
that the String does not contain illegal characters? In other words I need to filter all the
Strings that I return from the CXF soap service?

>             Project: CXF

>    Affects Versions: 2.1.2

> If my SOAP service returns a String that contains control characters and the service
is consumed by a CXF client a com.ctc.wstx.exc.WstxUnexpectedCharException is being thrown.
> It's easy to duplicate (in my setup) by modifying one line of the CXF 2.1.2 sample samples/java_first_jaxws:
>     public String sayHiToUser(User user) {
>         System.out.println("sayHiToUser called");
>         users.put(users.size() + 1, user);
>         return "Hello "  + user.getName() + '\27';          <<<===== add '\27'
to the String being returned
>     }
> Now when you start the client sample the following exception is being thrown:
> INFO: Interceptor has thrown exception, unwinding now
