As I said, the exception looks to me like an issue related to the JAXP
implementation you have installed as part of the JR. If you follow the
stack trace for this exception
org.xml.sax.SAXNotRecognizedException: Feature:
http://xml.org/sax/properties/lexical-handler
you'll see that EMF is trying to set up a lexical handler on the SAX
parser. That should just work, and clearly works most of the time (all
the time in my experience) except in this stand-alone environment your
running. What JRE are you using?

It sounds like it should be fine, but clearly it isn't. Given you have
both a context where it works and one where it doesn't, and you have a
stack trace for the point of failure, you're the one in the best
position to figure out why it would work in one case but not the other.
I seems to me this exception implies your JAXP implementation doesn't
support lexical handlers so you might look at the implement class being
used to implement the SAXParser interface in each case. You might try
this option to avoid needing lexical handler support:
/**
* Determines whether comments and CDATA will be preserved in any
mixed text processing.
* This option is applicable for loading XML resources (from DOM
node or an InputStream)
*/
String OPTION_USE_LEXICAL_HANDLER = "USE_LEXICAL_HANDLER";

First big big thanks. I tried to use my load options for the
editingDomain but i dont know to get it run?
try {
Resource resource = null;
Map options = new HashMap();
options.put(XMLResource.OPTION_EXTENDED_META_DATA, Boolean.TRUE);
options.put(XMLResource.OPTION_USE_ENCODED_ATTRIBUTE_STYLE, Boolean.TRUE);
options.put(XMLResource.OPTION_USE_LEXICAL_HANDLER, Boolean.TRUE);
try {
resource.load(options);
resource.resourceSet.getResource(fileURI, true);
} catch (IOException e) {
...
}
}
....
This wont work because resource is null. So how can i set the load
options? Must i use a XMLMap?

Mike,
Typically you set options in the resource factory that's used to create
the resource, but a resource set also getLoadOptions that will be
applied to all resources demand loaded in that resource set. Don't
specify more options than you actually need. You wanted to try
Boolean.FALSE for the lexical handler right?

I change OPTION_USE_LEXICAL_HANDLER in the
XYZBuildResourceFactoryImpl() to False. Works fine now. Thanks.
But cant i set the load optins in my Standalone Application? A
code Example would be useful?
Again big thanks
