Thanks, Jason Hodge jason.hodge@eesoh.com By: Lucian Chirita - lucianc RE: Sub-report class loader not filled in... 2005-12-16 00:09 Hi The REPORT_CLASS_LOADER parameter has been introduced in JR 1.0.3. This is way 1.0.1 does not fail. As a workaround, you could use java.util.HashMap instead of java.util.Hashtable as the former supports null values.
