[S2] Inappropriate Error Message
I'm developing using Struts 2 with the Spring plugin within Netbeans
5.5 using the embedded Tomcat as the servlet engine. If I screw up my
Spring applicationContext.xml by incorrectly specifying the path to
the class in a bean element, then when I try to deploy the project I
get the error message in the Tomcat start up logs.
SEVERE: Parse Fatal Error at line 1 column 1: Content is not allowed in prolog.
org.xml.sax.SAXParseException: Content is not allowed in prolog.
rather than a more helpful "can't find class foo.bar.baz.class" It's
not too big a problem at the moment as I only have half a dozen beans
defined, but for larger projects a more helpful error message would be
nice. Is this actually a Struts 2 issue, a Spring issue or a product
of my development environment?
Regards
Roger

I would suggest taking a Look at the XML and make sure there are no null's
cr's lf's tabs or other whitespace characters in the Input XML before
<?xml version="1.0" encoding="ISO-8859-1"? version="1.0">
The encoding attribute is specific to the version of browser
http://www.w3schools.com/xml/xml_encoding.asp
whereas version can either be "1.1" or "1.0"
http://www.w3.org/TR/2004/REC-xml11-20040204/#sec-version-info
be mindful that version="1.1" doc may invoke 1.0 external entities
but the reverse is not true..at least from I see in the doc available

This is repeatable by using a bogus class name, so that suggests that
Struts/Spring is the root cause.

Usually this means that there is something other than the BOM before
your <?xml processing instruction. Are you sure you don't have anything
before the beginning of your XML, or is this easily repeatable by simply
using a bogus class name?
Since this is a SAXException, I'm inclined to agree with Musachy that
this is likely to be an XML problem /before/ Struts gets involved
(loading classes, etc.).

That's a generic SAX exception, and I think in this case is coming from
Spring, right?
