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
