WstxUnexpectedCharException when returning a String from a CXF SOAP service
containing specific characters (used with CXF client)
---------------------------------------------------------------------------------------------------------------------------------
Key: CXF-1771
URL: https://issues.apache.org/jira/browse/CXF-1771
Project: CXF
Issue Type: Bug
Affects Versions: 2.1.2
Reporter: Martijn Brinkers
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
