You'll need to create a new WOComponent. Or just a class file that
extends from WOComponent.
Then override the appendToResponse and set the response content to the
data that you want to return. The tricky part is setting the mime type
correctly.
public void appendToResponse(WOResponse response, WOContext context) {
super.appendToResponse(response, context);
NSData content = yourDownloadableData();
if (content != null) {
response.setContent(content);
response.setHeader(new String("inline; filename=\"" +
"thefilename.ext" + "\""), new String("content-disposition"));
response.setHeader(Integer.toString(content.length()), new
String("content-length"));
response.setHeader(new String("CORRECTMIMETYPE; name=\"" +
"thefilename.ext" + "\""), new String("content-type"));
}
}

Hello -
Well for better or for worse I have decided to save my documents in the
database.
I made two EOs for this.. one to list them and then one to hold the
actual BLOB.
I am using mySQL for this.
I have successfully uploaded the file into the database. I now have a
page that lists
the files. I then created a hyperlink to bind to my download method:
public NSData downloadableData() {
NSData downloadable = null;
try {
downloadable =
theDocumentItem.projectDocumentObject().documentObject();
} catch (NullPointerException npe) {
System.err.println("Error: " + npe);
}
return downloadable;
}
This however always gives me ClassCastException. Any thoughts?
Thanks,
James Cicenia
