Hi there,
Im a  newbie, so I dont know If Im doing this thing right.

I am trying to create an XML file from a flat file and it keeps giving me errors.
Ok,Ive got the files all saved under D:\TEST_SERVINGXML, the files are the following: presentingxml.jar , objempr-servingXML.xml(the file that creates the XML file) and INFORMA_RE
JECT_FILE v2.txt (the txt file). I have writen the following in order to get the XML file, but it keeps giving me errors.

D:\TEST_SERVINGXML>java -jar presentingxml.jar objempr-servingXML.xml INFORMA_RE
JECT_FILE v2.txt ObjEmpresas

The error is as follows:
D:\TEST_SERVINGXML>java -jar presentingxml.jar objempr-servingXML.xml INFORMA_RE
