Re: [enhydra] InvocationTargetException

Hi,

For multiple database instances you should use:
<env-entry>
   <env-entry-name>DatabaseManager/Databases[]</env-entry-name>      
   <env-entry-value>setnet_host, setnet_stage</env-entry-value>
   <env-entry-type>java.lang.String</env-entry-type>
</env-entry>

Database driver must be loaded by the same class loader as DODS 
binaries. Therefore if you have DODS binaries loaded by 'Shared Class 
Loader' (loads binaries from <enhydra_root>/multiserver/shared/lib) you 
should place your driver binary here also (to be loaded by the same 
class loader). This way DODS will be able to see your driver implementation.

Additionally, when you are using DataSource DatabaseManager 
configuration your DataSource object is actually initialized by Tomcat 
itself. Therefore, in this case your DB driver implementation is not 
obligate to be placed together with DODS binaries (but Tomcat requires 
driver implementation to be placed either in 
'<enhydra_root>/multiserver/common/lib' or in 
'<enhydra_root>/multiserver/shared/lib').

Hope this clears things up!
