Hi All,

I have a Web Service written in Java (Web Logic) and I am trying to call it
in my ASP. NET client. I am facing a problem while getting the data from the
Web Service Method. My Web Service returns me an object which is a wrapper
around an array of objects. (Earlier I was trying to read the array directly
but could not succeed - so I wrapped that array with another object.)

Now the primary issue is regarding the chunky characters (Some character
data) that I am getting in the SOAP Envelope Response. I trapped the Response
with the TCPTrace and found that the data is getting chunked while transfer.

I am getting the data like this:

HTTP/1.1 100 Continue

In between the data there are some characters which are inserted by HTTP1.1
for chunking. This example shows only one object returned from the Web
Service. AS the objects increase, the chunked data also increase. Because of
this I am unable to deserialize the data on my ASP. NET client.
I get the following exception while doing the same...
System.InvalidOperationException: There is an error in XML document (1,
2998). ---> System.InvalidCastException: Cannot assign object of type
System.Xml.XmlNode[] to an object of type
JavaWSClient.SIWebService.CashflowViewList.

I don't know whether the error is coming because of the Encoding (encoded
instead of literal) or something else.
By default Web logic is returning me the WSDL with "RPC/Encoded" Encoding.

Please help me with some pointer regarding the error message that I am
getting at the client application. I am totally struck with the same and am
not in a position to proceed further.
