Allowing only zip files to be uploaded through af:inputFile ( in jdev 11g )

Question

I am able to upload all kinds of files through af:inputfile tag. I want to allow only zip files to be uploaded though the af:inputFile tag. Does inputFile provide any feature of this sort???

Answer 1

Let me address two issues here:
1. Chris has posted a correct answer about how to write a ValueChangeListener to allow only zip files. However, by the time this code runs, the file has actually already been uploaded to temporary storage. All this code does is specify what to do with the file once it is on the application server. So if you want to prevent the file from being uploaded unless it is zipped, this catches it too late. To catch it earlier, you have to write your own UploadedFileProcessor, and configure ADF to use it. Read more in Appendix A, section A.6.2.11 of the Fusion Web User Interface Developers Guide for Oracle ADF 11g.
2. While you have to write some code to handle uploaded files yourself (hey - it isn't a lot of code, and I don't care how declarative ADF is, sooner or later you're going to write a little code) if you are uploading to an ORDSYS.ORDDOC column in your Oracle database, ADF CAN do that declaratively.
