Package org.openxava.web.servlets

Class ZipFilesServlet

  • All Implemented Interfaces:
    java.io.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.
