How-to use GAE Blobstore Java API with GWT?

Question

I have GAE application and I'd like to download CSV file from Blobstore and display it in a table using GWT. Is there any example showing how to do this?

Answer 1

I think you'll just have to create a GWT-RPC service that reads the data from Blobstore using read(), converts the bytes back to csv, then puts it into some reasonable format (e.g., List<Row> or Map<String, Row> for some Row class you write) to return to the GWT client-side code.
