When i don't give the username, then it is showing an error window. If i don't give the password and don't confirm password then also it is giving error window, and if i just give any username and password and confirm password fields, (password and confirm password fileds are not same.) then it is not showing any error pages. It is showing http status 500 error.</p> <p>Here is my error log details.</p> <pre><code>Sep 22, 2013 4:59:47 PM org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: .:/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java Sep 22, 2013 4:59:47 PM org.apache.tomcat.util.digester.SetPropertiesRule begin WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:WebsiteProj' did not find a matching property.
