Re: Tomcat locking up, not responding to requests
Hi, Using Tomcat 5.0.28 standalone on windows XP with JVM 1.4, I get this error even though I have mapped my servlet in the web.xml file of the web app: HTTP Status 404 - /loginResponse.do type Status report message /loginResponse.do description The requested resource (/loginResponse.do) is not available. Apache Tomcat/5.0.28 I've placed my webapp folder in Tomcats' webapps directory and all the jsp pages run fine as do my POJO's for business logic, any ideas why the servlet code could be causing problems? The servlet mappings: code: -- loginResponse com._ABC.authenticateAdmin adminPassword xxx loginResponse /loginResponse.do -- It's my first time using Tomcat, been a Resin user for years ...
