So your question is not about Struts, it is about how to store binary data in a database? Try searching for "blob" (Binary Large OBject). Storing large amounts of binary data in a database is frowned upon in general. Databases are designed for storing and querying relational data. File systems are designed for storing binary data.
In any case, I'll move this post to the JDBC forum.
