Open browser in backend

Question

Hi,
First of all, when I click on the document link, the data will pull out from the database and display the contents within the browser by invoked the AFP web viewer plugin.
The method that I used to do that through setContentType("application/afp"), and using ServletOutputStream.
The case above happened when I only click on one document link.
However, I need to select multiple documents by checking the checkbox and print without opening them.
Therefore, I m just wondering that can I open the documents and invoke the plugin in the backend, which mean the documents is open up without user seeing it, is invisible to user. And then call the javaScript print to print the documents.
My concern is is it possible to do it this way?
Thanks

I expect some of your original description is happening on the client and some on the server. You didn't bother to explain which, so it's hard to understand. Perhaps you don't understand it yourself and that's your problem.
Anyway, using the HTTP protocol you can only return one thing in the response. What that "thing" can be depends on what's receiving the response, but in general if you're going to be returning more than one file in the response, you're going to have to package up the files according to the requirements of whatever is going to receive this multi-file package. So check the documentation of this AFP thing and see if it can receive multiple files, and if it can how it wants them packaged.
