I have some existing jsp pages and html pages which includes javascript as well. Due to the large number of the pages manual editing is not an option for me. So is there any tool which I can use to atleast help me convert them to some mobile compatible version.
I looked at jquery for mobile too but that doesn’t seem to have any convert option for existing files though for generating new files it is awesome.
Any help on this matter will be much appreciated.
I strongly doubt there is a tool for this, what would it even do? To make a page specially for mobile platforms is an extremly human task.
What you should do is take a look at your CSS files, which should be general for your whole application, and see what you can do with it. It might not be as good as pages specially designed for small screens, but you should be able to remove the worst problems.
