Re: how to export a ArrayList in gwt to external file?

Finally I use a textbox to store the search criteria history and set its visibility to false, then submit the form (FormPanel) to server and in servlet, get the textbox value using request.getParameter("XXX");
there is just some minor unknown about the RPC

An RPC expects an RPC serialized response

What does this exactly means? the response generated with ServletOutputStream.flush is not allowed, right?

Thanks for the help!!

Thanks for your reply.
yes, I am using rpc for the previous code.
to post a form, I remember FormPanel. but the example above is just a simplified case. in real, I need to pass a search history Map (time as the key, criteria string as the value) to servlet and use the servlet to export the Map content to a text file, Using FormPanel, how to pass the Map to servlet?
Also, seem this forum cannot edit post, so how to redact the titles of my previous attachment? delete it?
