Xmlparser.parse fails with ORA-20100 when reading from mapped network drive

Question

Hi
I have a problem with the xmlparser when parsing an xml document from a mapped network drive. If I read the xml document from a local drive, then there is no problem.
I haven't been able to find any documentation specifying this. Is there any way to parse a file from a mapped network drive???
To clarify, I have created an example procedure, that parses an XML doc from disc, notice that the G: drive is a mapped drive:
CREATE OR REPLACE procedure test_xmlparser is
p xmlparser.Parser;
dir varchar2(100) := 'G:\Vejdirektoratet\root\xsl';
errfile VARCHAR2(32) := 'error.log';
begin
p := xmlparser.newParser;
-- set parser properties
xmlparser.setValidationMode(p, FALSE);
xmlparser.setErrorLog(p, dir || '\' || errfile);
xmlparser.setPreserveWhiteSpace(p, FALSE);
-- parse xml file
xmlparser.parse(p, dir || '\' || 'HelloWorld.xml');
xmlparser.FREEPARSER(p);
end;
The file HelloWorld.xml contains the following:
<?xml version = '1.0'?>
<message>
<text>Hello World</text>
</message>
When running this in SQL*Plus I get the following error:
ORA-20100: Error occurred while parsing: Invalid argument
ORA-06512: at "SYS.XMLPARSER", line 22
ORA-06512: at "SYS.XMLPARSER", line 69
ORA-06512: at "VD.TEST_XMLPARSER", line 14
ORA-06512: at line 1
Changing the value of the variable dir to 'C:\' makes it all work.

Answer 1

Hi again
I need to ask a last, hopefully ;-), question on upgrading the JDK to 1.3.1:
As far as I understand, this is how I do it:
1) Install JDK 1.3.1 on DB server
2) tell Oracle DB, to use that JDK.
Is this the correct way? And how is step 2 done?
Looked on metalink, google etc., but could only find this for 9iAS (not the DB) and Oracle Applications 11i.
thanks, Sxren
