Test XSLT Server Extension on Tamino 3.1.1.1 - Storing Style

I have defined the doctype “xsl:stylesheet” in the collection “stylesheet” by using the enclosed schema file “Stylesheet.tsd” with the Schema Editor.

When I load the *.xsl file with Java Loader

java -classpath h:\xml_data\JavaLoader.jar;h:\xml_data\xerces.jar; c
om.softwareag.tamino.db.tools.loader.TaminoLoad -f h:\xml_data\list-filter.xsl -
u http://user:password@localhost/tamino/infotherm/stylesheet -d -p

then following exception messages returned:

ERROR: While checking API Version the following error occurred:
java.io.IOException: Server returned HTTP response code: 401 for URL: http://user:password@localhost/tamino/infotherm/stylesheet?_diagnose=apiversion
API Version = 1.0
TaminoLoad is started.
Block = 0, elements = 1

java.io.IOException: Server returned HTTP response code: 401 for URL: http://user:password@localhost/tamino/infotherm/stylesheet

Can anybody help me ?
