This week's book giveaway is in the Java in General forum. We're giving away four copies of Think Java: How to Think Like a Computer Scientist and have Allen B. Downey & Chris Mayfield on-line! See this thread for details.
I have a Struts 1.x application which serves a webpage for desktop users. Now I have to do an optimized version for smartphones which is working pretty nice. For this mobile version I have to filter out all images and make telephone numbers dialable in the mobile browser.
My plan was to use a filter which works on everything with /mobile/ in the url and basically do a .replaceAll(...). The filter is called but now I am stuck because I have no clue how to change the content of the response. All I find on the net is change content types. I also tried the getWriter() method to get the printwriter but I have no clue on how to change the text content of the repsonse.
