Be careful with that as you may not get the correct results What I would do is
transform to text/plain
Here is the GWT doc
The back-end server is expected to respond with a content-type of 'text/html',
meaning that the text returned will be treated as HTML. If any other
content-type is specified by the server, then the result html sent in the
onFormSubmit event will be unpredictable across browsers, and the
FormHandler.onSubmitComplete(FormSubmitCompleteEvent) event may not fire at
all.
Tip:
The initial implementation of FormPanel specified that the server respond
with a content-type of 'text/plain'. This has been intentionally changed to
specify 'text/html' because 'text/plain' cannot be made to work properly on all
browsers.
RequestBuilder.java integrates with RPC as demonstrated here
/*
* Internal method that actually sets our cached headers on the underlying
* JavaScript XmlHttpRequest object. If there are no headers set, then we
set
* the "Content-Type" to "text/plain; charset=utf-8". This is really lining
us
* up for integration with RPC.
*/
private void setHeaders(JavaScriptObject xmlHttpRequest)
{
XMLHTTPRequest.setRequestHeader(xmlHttpRequest, "Content-Type",
"text/plain; charset=utf-8");
}
So the solution is your server will transform your output from XML to
text/plain and send it back to the client as text/plain or JSON so that your
RPC plumbing will work..
Once that is working I would get your server to transform XML to HTML and send
that back
If you are constrained to implement XMLHttpRequest with content-type=text/xml
then look at Dojo as they
have a XSLTransform that works from the client (reference
/tests/xml/test_XslTransform.html)..although you may have to modify your XSLs
(full-page.xsl specifically) to properly transform and format your XML to HTML

Subject: Re: Calling Axis2 services from GWT
Hi,
I think Content-Type is not set right.
Try this,
builder.setHeader("Content-Type", "application/xml");
before builder.sendRequest().
If it doesn't work try, builder.setHeader ("Content-Type", "text/xml");
Hope this works

I am getting errors when I try to call an Axis POJO service from a Google
Web Toolkit application. The service I am trying to call is the sample service
called "Version". It returns a string with the Axis version number. The first
question I have is whether it is possible to call Axis2 services from non Axis2
clients. In my case, the client is an AJAX application built using GWT.
Here is the GWT code that makes the call:
public static void doGet(String url) {
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);
try {
Request response = builder.sendRequest(null, new
HTTPResponseHandler() );
} catch (RequestException e) {
System.out.println("Exception caught.");
}
}
Where url = "http://localhost:8080/axis2/services/Version/getVersion "
If I make the request as GET request, I get the following error:

If I make the request as a POST request, I get the following error:

If I hit the service from my browser, I get successful response:
<ns:getVersionResponse xmlns:ns=" http://axisversion.sample";>
<ns:return>Hello I am Axis2 version service , My version is
1.3</ns:return>
</ns:getVersionResponse>
The Axis2 service is the sample POJO service called "Version".
Any help or guidance would be greatly appreciated.
Best Regards.
