my java-servlet application working properly yesterday is not working now. application has not changed. when an exception occurs, application prompts error messages. But, it doesn't prompt anything now. Test case: click http://www.unal-bilisim.com/products/itrprof/itrprof.html don't select any thing. just click upload button. You should recieve: itp-02 [0] : Wrong file name. Cause : File name is not entered. Action : Enter file name. but, nothing appears in browser. application is same application.... I guess, this is a resin issue. thanks in advance...    More>>
