IE 5.5 SP1 posting twice on one Submit

spider737 · Feb 1, 2002

Has anyone noticed such an error previously? I've written a Java app that submits a form to a servlet (using Tomcat 3.3 and Apache 1.3.20--Java SDK 1.3.1) when a user wishes to save page values. I found that when the user presses the Save button on the JSP page, the servlet registers that a POST was made, then after some business logic executes, the servlet registers that a second POST was made. I'm checking on the page (using Javascript) that the button, even if pressed twice, will not submit the form twice, so I'm somewhat confused. Further, when I perform the same action using IE 5.00.2314, my servlet only registers that a single POST was made, as I expect. I've included the JSP below. I haven't seen any reference made to this issue on the Microsoft site or any other forums I've checked. Thanks in advance for any help.
