[opencms-dev] Connecting to a extern database

[Georgi Naplatanov]

If your database schema is ready, you can use OpenJPA's reverse mapping 
tool [1] to generate your persistence classes. It works well, but you 
have to adjust class names for multi-column primary keys and add @Lob 
annotation for binary fields and do not forget to use build time 
enhancement.

Using cache, database connection pool and prepared statements improve 
performance.

Best regards
Georgi
