I dont map the Result as it does not seem to need it, but if i do i get the same
problem so i dont think its that.
The problem manifests itself as follows;-
If i map the B8DisplayContext in the B8ElementTile class (as a returned parameter
called imageInfo) .. Note that i have also mapped the class in the sent parameter list
as a B8DISPLAYCONTEXT so in effect its mapped twice.
I find that SOAP ignores the mapping name (ie QName) and used the class as the
reference when it receives or sends a class that need serializing. This seems wrong..
I can demonstrate it as follows.
If i map the output parameter called viewContext (a B8DisplayContext) as follows
(contains 6 doubles: blX, blY, trX, trY, width, height)
smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "B8DISPLAYCONTEXT"), B8DisplayContext.class, new
org.apache.soap.encoding.soapenc.BeanSerializer(), new
org.apache.soap.encoding.soapenc.BeanSerializer());
(also the 6 doubles are mapped)
And i map the input element (B8ElementTile) as follows (contains String url, int
repositoryID, int mapLevelID, B8ElementContext imageInfo) .. note i have not mapped
the imageInfo but commenting it out
smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "url"), null, null, new
org.apache.soap.encoding.soapenc.StringDeserializer());
smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "repositoryID"), null, null, new
org.apache.soap.encoding.soapenc.IntDeserializer());
smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "mapLevelID"), null, null, new
org.apache.soap.encoding.soapenc.IntDeserializer());
// smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "imageInfo"), B8DisplayContext.class, null, new
org.apache.soap.encoding.soapenc.BeanSerializer());
I get the message
[SOAPException: faultCode=SOAP-ENV:Client; msg=No Deserializer found to deserialize a
':imageInfo' using encoding style

targetException=java.lang.IllegalArgumentException: No Deserializer found to

IE the imageInfo isnt mapped.... (as would be expected)
The output XML payload is as follows;- (sensible results are returned from this
message)

OK so i now add the mapping for the imageInfo into the B8ElementTile maps...

NOTE that the <viewContext>... line has a different namespace (ie imageInfo).... the
one i added in the B8ElementTile mapping which is obviously wrong......
Is this due to the mapping of types using the class name and not the parameter name
?????
By the way... i can put anything in the namespace and name in the mapTypes of
imageInfo and it will ALWAYS get back sensible results but will fail to map the
imageInfo back to its class. Note that the the <viewContext>.. line name changes
accordingly when i change these strings..
The sensible output is as follows

Ian,
Do you also map Result, e.g.
smr.mapTypes(org.apache.soap.Constants.NS_URI_SOAP_ENC, new
org.apache.soap.util.xml.QName("", "Result"), B8ElementTile.class, null,
new org.apache.soap.encoding.soapenc.BeanSerializer());
If so, it looks to me like Apache SOAP should be able to deserialize the
response. If you do have this mapping and it does not deserialize,
could you post the stack trace from the SOAP exception?
As for the message you are sending, is the server handling the
parameters correctly? STK 2 and .NET ignore parameters that have
xsi:type attributes when literal encoding is expected. If you need to
send literal encoding (well, if you want to suppress the xsi:type
attributes), you can do so with a nightly build of Apache SOAP. The
doclit sample shows how to specify "doc/lit" serialization by using the
new call.setDocLitSerialization(true) method. Caveat: don't be fooled
by the method name. This is a hack for improving interop that is not
perfect; it merely suppresses xsi:type and encodingStyle attributes.

I agree axis would work in this instance as i started with this solution
but the use of
AXIS breaks applet security policy, which is what we are designing. So i
need another solution.
The untyped nature of MS SDK means that it does not qualify each element
with its type so you would see entries like
<id>123</id> and not typed to an integer (or whatever)

I am not certain what "Server is MS SDK v3 (untyped)" means, or more
specifically, what "(untyped)" means. Does that mean the server uses
literal encoding of messages? If so, you should understand that Apache
SOAP has a couple of hacks to help it work in literal environments, but
does not have a full implementation. If you need to work with literal
encoding, you would do well to switch from Apache SOAP to Axis
(http://xml.apache.org/axis), which has much more complete support for
this.
If you want to resolve the issue you are having with Apache SOAP, could
you please post the mapTypes calls you are making? Also, wire dumps of
the SOAP messages would be of great help.

Subject: Complex types within complex types
serialization/deserialization
I have a problem with a complex type going into and out of a SOAP
routine in that it will not deserialize the resulting structure.
The setup is ..
I have a structure - DISPLAYCONTEXT that is send to a rpc service. This
service returns another structure, ELEMENT, that contains a
DISPLAYCONTEXT structure. So in effect I have
DISPLAYCONTEXT { int x; int y; } (as the input parameter)
ELEMENT { int z; String s; DISPLAYCONTEXT dc; } (as the output
parameter)
They are both configured as JavaBeans.
The problem is in mapping the types in the call. If i map the
DISPLAYCONTEXT and the returned 'dc' using SMR.mapTypes(), both as
beans, then the SOAP client complains that it there is no deserializer
for 'dc'. If i try any other way of mapping them i get the same message.
Note it doesnt work if i only map it once as a bean.
It seems that you can only map ONE class per call. i.e. i require to
map the same class twice (one for the output and one for the input), but
the mapping registry will only look for one and ignore the other causing
an error on deserialization.
Is there a correct way of mapping this ... or is it a bug in SOAP 2.3.1
??
MS SDK v3 returns a correct XML response.
Client is Apache SOAP 3.2.1, Server is MS SDK v3 (untyped).
