Re: Failure Parsing XML Document from Servlet

Hi AThinerCoin,

I agree with you : "I'm pretty sure it's not a GWT issue"...

1) if you want to serve XML from your servlet, why do you need to parse it ????? Simply serve it. That's all
2) did you set correct content type from your sevlet ? -> response.setContentType("text/xml");
3) did you close your stream with the close() method of the OutPutStream ?
4) your GWT client receive a raw XML stream. What do you do with it ?

I hope it helps.

Regards.

I'd like to pass an xml file to my gwt client.  I created another
servlet that fetches it from the local file system and returns the xml
file when I call its url.

If I go to the url from my browser, it looks fine.  If I fetch the url
from curl, it uses the &gt;&lt; kind of format.  If I fetch the url
from my gwt client, I get different results and error messages in
development versus production mode.

If I archive the xml file directly into the war, my program works
perfectly.

I'm pretty sure it's not a GWT issue, but I'm not sure where else to
turn.  Any guidance would be appreciated.

In development, it looks like I don't get a result at all and my error
is:

In production, I get what looks like the right result back (based on
