XMLType and External Entity Resolving

Question

When I try to insert an XML Document like
my table "xmltest" have only one column from type XMLType.
insert into xmltest(xmlType('<?xml version="1.0" encodeing="ISO-8859-1"?>
<!DOCTYPE test PUBLIC "/home/oracle/test.dtd"><test>&amp;auml;</test>'));
i become an Error
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00226: entity "auml" is not declared
Error at line 2
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 1
my question is
is it possible to declare external Entity references in a DTD File, and how i can bind the xmldata to that DTD File
i dont want to put the Entity Declaration into the xmlDocument (as inline DTD)
kind regards
jan

Answer 1

Yes,
outside from XML DB i can parse the file,
it parse also with PL/SQL
but there, the DTD is under an apache URL (http://apachehost/dtd/test.dtd) and dont need Authentification.
in this conjunction the DTD is under "http://testhost:8080/public/test.dtd" and need Authentication and also i think that the XmlType parsing failed.
I have try´d out to Access the DTD with
select xdburitype('http://testhost:8080/public/test.dtd').getClob() from dual;
i get an error with Access Denied
with
select utl_http.request('http://testhost:8080/public/test.dtd').getClob() from dual;
i get the File
The test.dtd was placed with Windows OS over the WebDav function. The file can be accessed from outside the XML DB with Authentication
My Question are
- must this resource explicit registered in the XML DB
- can this happends on other things
- how i can set the Accessability from the resource
