Class ZipFilesServlet

java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
org.openxava.web.servlets.ZipFilesServlet
All Implemented Interfaces:
Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
@WebServlet("/xava/zipfiles") public class ZipFilesServlet extends javax.servlet.http.HttpServlet
Servlet to download all files of a @Files property as a single ZIP.

It is invoked from the upload editor's "Download all" link and streams a ZIP containing all files stored in the library identified by the current value of the property in the active view.

Endpoint: /xava/zipfiles

Expected request parameters (query string):

  • application: OpenXava application name.
  • module: OpenXava module name.
  • propertyKey: Decorated id of the @Files property (for example, xava_App_Mod_prop).
  • windowId: Current window id (used by OpenXava context).

Behavior:

  • Initializes the OpenXava request context and default schema.
  • Resolves the current View and obtains the library id from the property value.
  • Loads all files via FilePersistorFactory and builds a ZIP on the fly.
  • Sets Content-Type to application/zip and a safe file name in Content-Disposition.

Responses:

  • 200 OK: Streams the ZIP.
  • 400 Bad Request: No active view.
  • 404 Not Found: Property has no library id or library has no files.
  • 500 Internal Server Error: Any unexpected error while building the ZIP.

Notes:

  • Zip entry names are sanitized and de-duplicated to avoid path traversal and collisions.
  • This servlet relies on OpenXava context; it is not intended to be used directly without it.
