Subject AW: datasource-realm troubles
Date Tue, 30 Jan 2007 15:11:49 GMT
Problem solved.

The missing glue is, if you define Realm and DataSource inside the Context, don`t forget to
specify 

	localDataSource="true"

	When the realm is nested inside a Context element, this allows the realm to use a DataSource
defined for the Context rather than a global DataSource. If not specified, the default is
false: use a global DataSource.

Thanks to Alessandro

regards Oliver
