Server response not UTF-8 encoded (but claims to be)
----------------------------------------------------
Key: AXISCPP-964
URL: http://issues.apache.org/jira/browse/AXISCPP-964
Project: Axis-C++
Type: Bug
Components: SOAP
Versions: current (nightly)
Environment: All platforms, except OS/400
Reporter: Henrik Nordberg
(See the end of this description for a one-liner that works around this problem
for most cases.)
SoapSerializer.cpp, line 379 says
serialize( "<?xml version='1.0' encoding='utf-8' ?>", NULL);
that is that the SOAP response is UTF-8 encoded. But this is only true for
OS/400 as can be seen in HTTPTransport.cpp, lines 311-
#ifndef __OS400__
*m_pActiveChannel << this->getHTTPHeaders ();
*m_pActiveChannel << this->m_strBytesToSend.c_str ();
#else
// Ebcdic (OS/400) systems need to convert the data to UTF-8. Note that
free() is
// correctly used and should not be changed to delete().
const char *buf = this->getHTTPHeaders ();
utf8Buf = toUTF8((char *)buf, strlen(buf)+1);
*m_pActiveChannel << utf8Buf;
free(utf8Buf);
utf8Buf = NULL;
utf8Buf = toUTF8((char *)this->m_strBytesToSend.c_str(),
this->m_strBytesToSend.length()+1);
*m_pActiveChannel << utf8Buf;
free(utf8Buf);
utf8Buf = NULL;
#endif
This leads to clients trying to decode the response as UTF-8, and will have
errors whenever the response contains non-ASCII characters (i.e., > 127).
Axis Java, for example, will prduce this error upon decoding:
"java.io.UTFDataFormatException: Invalid byte 2 of 3-byte UTF-8 sequence."
A simple workaround is to change SoapSerializer.cpp, line 379:
from
serialize( "<?xml version='1.0' encoding='utf-8' ?>", NULL);
to
serialize( "<?xml version='1.0' encoding='ISO-8859-1' ?>", NULL);
The real fix, however, is to encode the response with UTF-8 for all platforms
(not just OS/400).
