If i don't use "openjpa.ConnectionURL" this error appears for me

Yes, i made a test with the data sources separately, without the Slice, with
only "openjpa.ConnectionURL", both works.
I don't know if this properties are correct, because i follow the example of
"openjpa.ConnectionUserName", in the site
"http://people.apache.org/~ppoddar/slice/site/index.html";, these properties
doesn't exists. I put because a think that is correct, but i don't know.
<property name="openjpa.slice.SQLSERVER.ConnectionUserName" value="sa"/>
<property name="openjpa.slice.SQLSERVER.ConnectionPassword"
value="testando123"/>
thanks
