Problem handing bitflag enums in Axis2 serialization.
System.flags is used in dotnet to identify a bitflag enum, where one
value is associated with each bit of the enum, and multiple values/bits
can be set for the value of the enum (see dotnet generated WSDL below).
The problem is, how do you specify the null set, and can Axis2 handle
such a case in serialization? Enums are a tricky type since their
representation as a numeric entity (bits) making them a non-nullable
type, although their value is transfered as a string with multiple
concatenated enum values.
There are two classes generated by wsdl2java to handle the bitflag enum
at the server (eg. EnumMWSSearchFlags, EnumMWSSearchFlags_type0- see
attached). EnumMWSSearchFlags contains an array of
EnumMWSearchFlags_type0, each element of which can refer to a bit value.
Both dotnet and java clients serialize the empty set as a zero length
string. This zero length string is parsed, at the server, looking for
individual enum values. Of course, none are found, and when the zero
length string is used in a table lookup for valid members of the enum
(in EnumMWSSearchFlags_type0) an IllegalArgumentException is generated.
I have been able to get this to work by commenting out the check for
valid enum members being passed in, but obviously this isn't the best
way to do this (see specific commented out code below).
Shouldn't Axis2 generated serialization handle the special case where a
zero length string is passed in as the value of a bitflag enum??
Thanks, Dave Kraus
Altered code - see comment:
public static EnumMWSSearchFlags_type0
fromValue(java.lang.String value)
throws java.lang.IllegalArgumentException {
EnumMWSSearchFlags_type0 enumeration =
(EnumMWSSearchFlags_type0)
_table_.get(value);
//drk: Comment out so that bitflag enum can accept
an emptyset enum
/*if (enumeration==null) throw new
java.lang.IllegalArgumentException();*/
return enumeration;
}
WSDL representation of a bitflag enum:
<s:simpleType name="EnumMWSSearchFlags">
<s:list>
<s:simpleType>
<s:restriction base="s:string">
<s:enumeration value="MWSAbbreviationWildCard"/>
<s:enumeration value="MWSDescriptionWildCard"/>
<s:enumeration value="MWSFolderBrowseStyle"/>
<s:enumeration value="MWSModificationTime"/>
<s:enumeration value="MWSNameWildCard"/>
<s:enumeration value="MWSRootRecursive"/>
<s:enumeration value="MWSUsedByOneOf"/>
<s:enumeration value="MWSUsedByRecursive"/>
<s:enumeration value="MWSUsesOneOf"/>
<s:enumeration value="MWSUsesRecursive"/>
<s:enumeration value="MWSVisibleOnly"/>
<s:enumeration value="MWSBrowseAsync"/>
<s:enumeration value="MWSOwnedByCurrentUser"/>
</s:restriction>
</s:simpleType>
</s:list>
</s:simpleType>
WSDL representation of usage of the bitflag enum as a parameter showing
minoccurs=1 because it's a non-nullable type.
<s:element maxOccurs="1" minOccurs="1" name="eFlags"
type="tns:EnumMWSSearchFlags"/>

Dims,
Wow. thanks!! I didn't expect such a quick response with an example in
jyhton...
Thank you very much. You've made my week. I've been struggling with this
for a while now. I was expecting it to be harder.
Regards,
Greg.

How to handle soap faults?
Posted by "Moore, Greg" <Gr...@adp.com>.
Hi,
Done some searching of axis and other lists as well as google searches
and I haven't come up with anything that explained what I am wondering
about.
I'm posting an xml file containing a soap envelope to a service and I
get back a xml response that will either contain a soap fault or a CDATA
element. I'm using apache commons HttpClient to do this.
My question is it possible to use Axis to handle soap errors and/or
faults using this method. If it is a pointer on how to do it brief
example would be greatly appreciated.
Thanks in Advance,

can I handle soap faults when using httpClient?
Posted by "Moore, Greg" <Gr...@adp.com>.
Hi,
Done some searching of axis and other lists as well as google searches
and I haven't come up with anything that explained what I am wondering
about. Maybe some kind person will take pity on the confused. :)
I'm posting an xml file containing a soap envelope to a service and I
get back a xml response that should contain a CDATA element. I'm using
apache commons HttpClient to do this. Below is the essential Jython code
that I'm using as an example similar to what I'm doing. I originally
was trying to do this using Axis but after several days of trying was
never successful.
My question is it possible to use Axis to handle soap errors and/or
faults using the method below or do I have to parse xml or beat my head
against a wall until I figure out how to get the axis client to work.
from org.apache.commons.httpclient import *
from org.apache.commons.httpclient.methods import *
from java.io import File
xmlData = File(xmlFilename)
length = xmlData.length()
url = "http://myserver.somewhere.com/ services/Check.asmx"
soapAction = "http://GateWay/Services/CreditCheck/GetReportXml"
post = PostMethod(url)
entity = FileRequestEntity(xmlData, "text/xml; charset=utf-8")
post.addRequestHeader("Content-Length", str(length))
post.setRequestEntity(entity)
post.addRequestHeader("Content-type", "text/xml; charset=utf-8")
post.addRequestHeader("User-Agent", "SQA_TestClient0")
post.setRequestHeader("SOAPAction", soapAction)
httpClient = HttpClient()
statusCode = httpClient.executeMethod(post)
if statusCode == HttpStatus.SC_OK:
resultText = post.getResponseBodyAsString()
else:
# I'd like to check for soap fault here instead of a generic
# failure.
print " failure: " + post.getStatusLine().toString()
Did I mention I was new to Axis? :)
Thanks in advance,
