I have an Axis Web service developed on Java, which is accepting XML as input and returns XML as output. While I am invoking the webservice from Java client, the input is in form of a proper XML, while when I am invoking the web service from MS .NET client, the XML tags are getting distorted. i.e < is getting converted to < and > is getting converted to >. Can anyone help to locate and rectify the problem?

My Web Service is written in Java, hoisted on Axis 1.1 platform. The Web service takes Element(of org.apache.w3c.Element) as input arguments and returns Element as output. It takes XML as input and returns XML as output. The XML exchange is supported on SOAP protocol. I am trying to access my webservice from .NET client. I have converted the WSDL file to generate the client stub. In the client code, I have defined an object of XmlDocument type and loaded an XML from XmlDocument.Load method and passed the XmlDocument.OuterXml as input. However, when I am monitoring the input on my webservice, I am receiving the SOAP envelop in XML(i.e with opening and closing angular bracket <>), but the XML content, read from the file is getting distorted. The < is getting converted to < and > converted to >. Please help.

OuterXml is a string representation of the XML so that's what gets passed to the service. If the service expects an element then try passing XmlDocument.DocumentElement instead.
If the problem is strictly on the receiving side do you have a link to the WSDL?

Tried the solution. But .NET is giving an error:System.InvaliOperationException: There was an error generating the XML Document. -->The type System.Xml.XmlElement may not be used in this context.

Okay, without the WSDL it's hard to help though.

Hi
I have a web service hosted in WSAD developed in JAVA working on Axis 1.x platform. This web service receives an XML input and returns an XML output. I am trying to consume the web service from a .NET client.
I tried to create the proxy class to invoke the web service referred to by above WSDL by using the wsdl.exe utility of .NET.
I have written a seperate piece of code to invoke this proxy class and to invoke the web service in turn.
Now, when I am invoking the web service from the caller class, I am passing the XML, but the return object is NULL. On inspection of the actual input to the web service, I found that the XML being passed to web service as SOAP body is getting distorted. The < of XML is getting converted to "<" and the > is getting converted to ">". I am not able to figure out what the problem is. However, the angular brackets in the SOAP header is remaining intact and correct.
Can anyone please help?
Also, the return from the web service being caught in the caller class is getting NULL.

Hi Koushik,
I wonder if you were able to resolve this problem. I am having a similar problem. Like to know if the problem was at the .net client side or webservice (java) side
Thanks
