Subject Re: How do you pass an XML document between Axis and .Net Client?
Date Mon, 03 Jun 2002 15:38:51 GMT
This all sounds good, and I have been able to pass XML documents back 
and forth as RPC and Document parameters.  The problem is getting it to 
work with .NET.

1. I haven't found a way to access the Document parameters on the .NET 
side.  If somebody has an example, that would be great.

2. I have tried the XML to string route, and it *should* work, 
unfortunately, I get the following error:

String in is <?xml version="1.0" encoding="utf-16">
<test>
   <name>
     Robert Evans
   </name>
   <time tz="EST">
     12:10
   </time>
</test>
- Exception:
org.xml.sax.SAXException: Fatal Error: URI=null Line=1: Character
conversion error: "Missing byte-order mark" (Line number may be too low).
    at 
org.apache.axis.utils.XMLUtils$ParseErrorHandler.fatalError(XMLUtils.java:472)
    at ....


Note that the String is passed in, but I get this mysterious error on 
the XMLUtils utility.  Source code is below:

	System.out.println("String in is " + string);
	StringBufferInputStream is = new tringBufferInputStream(string);
	Document doc = null;
	doc = XMLUtils.newDocument(is);
	    // if you use parse() you use a string of an ELEMENT as put.
	    // This does not contain the xml declaration that is in most
	    // Documents/files
	    // doc = db.parse( is );
	if (doc == null) {
	    return "HelloWorld6.sayHello() had an error parsing the input";
	}

My problem is that I can't figure out one way to have these two 
platforms (Axis and .Net) pass an XML document!
