VFSServlet.JdbcFileDAO (BCD-UI Api)

java.lang.Object
- de.businesscode.bcdui.vfs.web.VFSServlet.JdbcFileDAO

All Implemented Interfaces:

VFSServlet.FileDAO

Enclosing class:

VFSServlet
```
public static class VFSServlet.JdbcFileDAO
extends java.lang.Object
implements VFSServlet.FileDAO
```
unfortunately we cant work with DatabaseFileSystem / DatabaseFileObject directly to store data, so we do here lowlevel BLOB handling, works with bcd_virtualFileSystem binding-set NOT THREADSAFE
