Bizarre Web Service Error

[Jay Robinson]

The following text is the result of calling a web service
(FN003) locally using the test page. During its
processing, the web service calls a second web service
(FN006) on the same box.

It appears to be searching for a missing temporary dll,
though I have no idea why. The name of the dll changes
from one call to the next. Any help would be greatly
appreciated.

[Dino Chiesa [Microsoft]]

there is an error in the XML serializer than can sometimes lead to this
symptom.
In the case where you have particularly complex object graph, involving
jagged arrays without a specific attriubute applied to them, the Xml
Serializer will choke. If you apply the attribute, the serializer will be
fine.

See [url]http://tinyurl.com/rqwl[/url]

to troubleshoot this, I would recommend:
1. examine your datatypes for a jagged or 2-d array
2. simplify the data types being sent and received to simple types
3. add in complexity, until you see the error
4. apply the attribute and see if this resolves your issue

There can be other causes of this mystifying message, but this is the one I
have seen most commonly.
