Hello,

I have a web service of my own on a server (vb.net). I must declare it with
SoapRpcMethod to be used with JAVA.
This is a simple exemple method of my vb source :

>************************************************************************
> <WebMethod(), System.Web.Services.Protocols.SoapRpcMethod()> _
> Public Function HelloWorld() As
> <System.Xml.Serialization.SoapElementAttribute("return")> String
> HelloWorld = "Hello World"
> End Function

>************************************************************************

The web service seems to be ok, i can access all methods and they work
correctly with the local page generated by iis on the web service url.

The problem is when i want to access the web service methods with a vb form
client.
I create a form, add w.s. reference to the project. This is the code behind
generated by dot net :

>************************************************************************
>
> <System.Web.Services.Protocols.SoapRpcMethodAttribute("http://tempuri.org/CorusFortisDocumentService/RPCCorusFortisDocumentService/Hello"&
> _
>"World",
>RequestNamespace:="http://tempuri.org/CorusFortisDocumentService/RPCCorusFortisDocumentService",
>ResponseNamespace:="http://tempuri.org/CorusFortisDocumentService/RPCCorusFortisDocumentService")>
>_
> Public Function HelloWorld() As
> <System.Xml.Serialization.SoapElementAttribute("return")> String
> Dim results() As Object = Me.Invoke("HelloWorld", New
> Object(-1) {})
> Return CType(results(0),String)
> End Function

>************************************************************************

All seems to be ok but when i call the method an exception is generated at
the Invoke method :

>************************************************************************
>Une exception non gérée du type
>'System.Web.Services.Protocols.SoapException' s'est produite dans

It is the exception when i try it on my WXP with the w.s. on the same box. I
have the same when i put the w.s. on my W2K3S + IIS and i call the method
from my client :

>************************************************************************

Hi Olivier,

Welcome to webservice newsgroup.
From the description of your problem, the webservice's serverside can not
load a certain assembly and that assembly is a random generated one (for
XML serialization .....)... I suggest try accessing the webservcie from
different cliente machine and also check the server's IIS log to see
whether the request have actually arrived the IIS server. If the request
did arrrive IIS server , then we can focus on the serverside... You can
try creating some other simple webservcie on the same server to see whether
it also suffer the same problem.

If there're anything else I missed, please feel free to post here.

Regards,

Steven Cheng

Hi Steven,

I see the client calls in IIS :
22:49:03 127.0.0.1 POST
/CorusFortisDocumentService/CorusFortisDocumentService.asmx 200

I've included the source code of my asmx page in this post (it's a very
simple source).
If i use the source like this my form client can access the IsAlive method.
If i uncomment line 4 and delete line 5 to put it in SoapRPC my form client
raise an exception like the one i described under with a rando generated
assembly name.
I also found that if i comment the method called GetDocumentListByIdAndDate,
i can call the IsAlive normally with class declared SoapRPC. It seems that
only when this method is present all the call from my form will finished in
exception. This method return an array of a type generated with
xsdobjectgen.
I really don't know why, do you have an idea ?

Thnaks for your help.
