When you say the problem is on Linux but works fine on Windows, do you mean: a) If you deploy the servlet to a jboss as running on Windows, then when users access the data it works correctly, but when you deploy he servlet to jboss as running on Linux then when the users access the data they get the old data? b) When users running a browser on Windows access the data they get the correct data, but when users running a browser on Linux access the data they get old data? If the answer is (b), what browser if being used on each system? Also, if the Linux user hits the refresh button on the browser, does the correct data show up?
