<blockquote>Locking duplicate thread.<br> Please continue here: [[/questions/931312]]</blockquote> Hi, We have one application with Websphere portlet Factory generated JSP as front end, Java in the business layer and finally DB2 as back-end. In certain cases it is being observed when exception has occurred and error page is shown, if we refresh/reload the page the input data is being corrupted if they are Japanese character set and that corrupted character set is then submitted to the server. This is observed only for Japanese characters, for English char set its working as expected. Our query here is who is responsible for gathering form data and resending the same if reload/refresh is pressed? Does the browsers do it or something else? Basically we want to trace the root cause for the corruption of Japanese char set. Your inputs are highly appreciated. It will help us to have better insight about the problem. Thank you for your time.
