How to inject complex Map (such as Map >)

[gushen yuan]

  I can not found openEjb which can inject complex map. How to inject complex 
Map (such as Map <String, Map<String,String> >)?   I try to create custom 
resources (Map <String, Map<String,String> >). But I am not found any function 
for custom resources in openEjb.xml. Thanks!
