WFC problem

[Marco Pais]

Hi there.

I'm having a problem with a Web Service that I've created. This WS has
several simple methods, that are working fine... no problem with code.

However, when retieving a bigger number of rows, I get this error:

"The maximum message size quota for incoming messages (65536) has been
exceeded. To increase the quota, use the MaxReceivedMess ageSize property on
the appropriate binding element. "

I then searched google for some help/explanation and I found this site,
amoung others:

http://forums.microsoft.com/MSDN/Sho...34670&SiteID=1

Initialy, my web config on the server is like this:
------------------------
<?xml version="1.0" encoding="utf-8"?>
<configuratio n>
<system.web>
<compilation defaultLanguage ="c#" />
</system.web>

</configuration>
------------------------

If I follow the instructions on that post, my WS returns error.

How can I configurate this??

Thanks in advance,

Marco

Are you sure that is your web.config? WCF typically has a LOT more
config than that (in system.ServiceM odel), for either the client or the
server.

If your app is setting up the configuration through code (which is
entirely possible with WCF) then you need to find the bit of code that
configures the binding. Note that these quotas don't just apply to the
server; setting it at the server is useful for uploading larger arrays
etc, but the quotas may need to be independently set at the client if
the problem is the server *returning* too much data.

I've re-read your post, and indeed it looks like a client issue; try
changing app.config at the client instead. For example, for basic-http
you might have:

<bindings>
<basicHttpBindi ng>
<binding ... maxReceivedMess ageSize="655360 0" maxBufferSize=" 6553600">
<readerQuotas maxArrayLength= "250000" />
</binding>
</basicHttpBindin g>
</bindings>

Additionally, you might want to think about using streamed MTOM if you
are returning binary; you can add transferMode="S treamed" and
messageEncoding ="Mtom" to "binding" for basic-http (but not for all
bindings) - but you need to do this at both the client and the server or
it will break [which is why I didn't add them above].
The quotas etc should be fine set at one end only (since it is expected
that client and server should have different quotas).

Thanks for the reply.

So, you say that I can configure client independently, without the need to
configure the server? The problem is when downloading data, never with
upload. And how can I do this? Because I used this client config:

<?xml version="1.0" encoding="utf-8" ?>

<configuratio n>

<system.service Model>

<bindings>

<basicHttpBindi ng>

<binding name="ServiceSo ap" closeTimeout="0 0:01:00" openTimeout="00 :01:00"

receiveTimeout= "00:10:00" sendTimeout="00 :01:00" allowCookies="f alse"

bypassProxyOnLo cal="false" hostNameCompari sonMode="Strong Wildcard"

maxBufferSize=" 65536" maxBufferPoolSi ze="524288"
maxReceivedMess ageSize="65536"

messageEncoding ="Text" textEncoding="u tf-8" transferMode="B uffered"

useDefaultWebPr oxy="true">

<readerQuotas maxDepth="32" maxStringConten tLength="8192"
maxArrayLength= "16384"

maxBytesPerRead ="4096" maxNameTableCha rCount="16384" />

<security mode="None">

<transport clientCredentia lType="None" proxyCredential Type="None"

realm="" />

<message clientCredentia lType="UserName " algorithmSuite= "Default" />

</security>

</binding>

</basicHttpBindin g>

</bindings>

<client>

<endpoint address="http://servidor:8080/ws/Service.asmx"
binding="basicH ttpBinding"

bindingConfigur ation="BasicHtt pBinding_IOrder Service"
contract="IOrde rService"

behaviorConfigu ration="LargeQu otaBehavior"

name="ServiceSo ap" />

</client>

</system.serviceM odel>

</configuration>
and I get this error:

"There is no endpoint behavior named 'LargeQuotaBeha vior'. "

Thanks in advance.

behaviorConfigu ration relates to the "behaviors" element, and can be
used to create your own stack with custom listeners etc. I think you can
remove this attribute; bindingConfigur ation relates to the binding -
you've named this "ServiceSoa p", so this is what the
bindingConfigur ation attribute should say.

"BasicHttpBindi ng_IOrderServic e" looks like it should be the name (which
can often actually be left blank).

So try:

<client>
<endpoint address="http://servidor:8080/ws/Service.asmx"
binding="basicH ttpBinding"
bindingConfigur ation="ServiceS oap"
contract="IOrde rService"
name="BasicHttp Binding_IOrderS ervice" />
</client>

If you get errors about not finding the configuration, try removing the
name attribute. Also - I'm a little worried about it finding the
contract - I usually use the full-qualified name
(Foo.Bar.IOrder Service), but if it works...

So, you say that I can configure client independently,

without the need to configure the server?

This is pretty-much limited to quotas, maximum sizes, and behaviors
(i.e. a behavour can be used to inject error-handling or performance
metrics - these aren't part of the channel itself). Pretty-much
everything else must match. It will tell you soon enough if there is a
problem...
