6.10. File Upload, File Download, Showing Image Files, and Playing Audio Files You can generate File Upload, and depending on the type of file, File Download or Show Image or Play Audio for database columns of types ORDSYS.ORDDOC, ORDSYS.ORDIMAGE and ORDSYS.ORDAUDIO. If you have stored your files in BLOB columns instead, see section Using JHeadstart File Up/Download on BLOB Columns. Attention: The abovementioned types are object types defined in the Oracle interMedia feature of the Oracle database. The ORDSYS.ORDDOC type can store any heterogeneous media data including audio, image, and video data in a database column. ORDSYS.ORDIMAGE can process and automatically extract properties of images of a variety of popular data formats, and ORDSYS.ORDAUDIO can process audio specific properties. For more information, see the interMedia section of the Oracle Technology Network (http://otn.oracle.com/products/intermedia). Example of generating a file upload field in the HR sample schema for uploading photos of employees: 1. Make sure you have a table with a column of the correct datatype. This is sufficient: alter table EMPLOYEES add photo ordsys.ordimage; 2. Add the new Photo attribute to the ADF Entity Object and ADF View Object for Employees. 3. Add the Photo item to the Employees group of your JHeadstart Application Definition (by synchronizing the group) and generate your application. You will get something like this: With the Browse button you can select the image file you want to upload for this record. 3. If instead, you want that field to display the photo, you can change the Display Type of the item to image. 4. If instead, you want that field to display a hyperlink that downloads the file in a separate window, you can change the Display Type of the item to fileDownload. Attention: The display type ‘image’ means that ADF Faces renders the file as a download link, image, or audio player, depending on the nature of the individual file. After changing the Display Type to image and regenerating, you will get something like this (do not forget to upload a picture first!): 6- 24 Generating User Interface Widgets JHeadstart Developer’s Guide
6.10.1. Combining File Display Options If the file you uploaded was an audio file (this is possible with the ORDDOC and ORDAUDIO types), you will get something like this: Suggestion: By default there are limits on the size of the file that can be uploaded. If they are exceeded, you get a Java exception: java.io.EOFException: Per-request disk space limits exceeded. If you want to change the file size limitations, have a look at the Development Guidelines for Oracle ADF Faces Applications, chapter File Upload, section Configuration, at http://www.oracle.com/technology/products/jdev/htdocs/partners/addins /exchange/jsf/doc/devguide/fileupload.html - Configuration. For generating both file upload and file download (or image or audio player) for the same database column, create an extra item as follows: 1. Open the Application Definition Editor. 2. Add an extra item to the group. 3. Copy all properties of the original file item (Photo). 4. Change the Name of the new item (for example to ShowPhoto), and change the Display Type to fileDownload or image. 5. Consider to change the prompt of one or both of the Photo items If you don’t change the prompts, you will get something like this: JHeadstart Developer’s Guide Generating User Interface Widgets 6- 25
