hi am having problem to deploy my java web application. I'm using myEclipse for spring 10 and tomcat 7.
am having these errors:

org.apache.catalina.core.StandardContext startInternal
SEVERE: Error listenerStart
org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/projectname] startup failed due to previous errors

Anyone know how to solve this issue?

As from http://stackoverflow.com/questions/13115880/how-to-deploy-war-file-in-eclipse-to-tomcat-server

ok I figured it out my self. I searched the google for

SEVERE: Error filterStart
and found, check the localhost_yyyy_mm_dd.log file for more information about error.

In that file there was an error called java.lang.UnsupportedClassVersionError. The reason for that was my jdk and jre versions are different.

So I changed jdk and jre versions as same level from project properties. after that I built the project and exported the project to webApp again. I restart the tomcat server again. All errors are gone.

This might help you to solve your problem.

may be renaming the default servlet to something else like myDefaultServlet in web.xml could help.
