Subject [jira] Created: (AXIS2-3238) Encoding of text messages using SOAP over JMS
Date Tue, 02 Oct 2007 06:47:50 GMT
Encoding of text messages using SOAP over JMS
---------------------------------------------

                 Key: AXIS2-3238
                 URL: https://issues.apache.org/jira/browse/AXIS2-3238
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
            Reporter: Leo Huber


Hi,

I am new to axis2 and jms. We are sending soap messages over JMS textmessages. We are struggling
with a encoding issue and 
I tried to find the source of the problem. I found that the class JMSSender handles receiving
jms text messages like any other message and creates a 
bytestream using the getInputStream method in JMSUtils. However, the bytestream is either
encoded with the encoding set in 
the message or with the default encoding of the operating system (see the copy of the method
below). Later this bytestream is
used to create a SOAP Message object using the encoding set in "Constants.Configuration.CONTENT_TYPE".
This leads to an encoding
issue if the encoding used to create the byte stream and the encoding to read the byte stream
(create the soap message)
are not the same. 

We are developing on windows machines but are testing on linux machines which both have different
default encoding set in the jvm. Therefore, because of the 
behaviour described above axis2 behaves differently on linux and windows. However, I don't
see why axis creates a byte stream with a possibly different encoding
than creating the soap message with that stream.

Regards
Leo
