I had the same problem  and the cause was the missing of  commons-logging-1 2 jar  I add it to the lib folder  then my Apache Tomcat 7 server executed without problems

Your web app has servlet container specific libraries like servlet-api jar file in its  WEB-INF lib  This is not right  Remove them all  The  WEB-INF lib should contain only the libraries specific to the Web app  not to the servlet container  The servlet container  like Tomcat  is the one who should already provide the servlet container specific libraries  If you supply libraries from an arbitrary servlet container of a different make version  you ll run into this kind of problems  as your web app wouldn t be able to run on a servlet container of a different make version than those libraries originated from   This is a pretty common starter s mistake when they encounter compile-time errors  as they haven t set up their IDE project right  See also How do I import the javax servlet API in my Eclipse project

This one is for all the Maven users out there  using their dependencies for the classpath and not copying them into  WEB-INF lib  just add this  which copies the dependency libraries  before  lt  plugin gt    lt plugin gt       lt artifactId gt maven-dependency-plugin lt  artifactId gt           lt executions gt               lt execution gt                   lt phase gt process-sources lt  phase gt                   lt goals gt                       lt goal gt copy-dependencies lt  goal gt                   lt  goals gt                   lt configuration gt                       lt outputDirectory gt WebContent WEB-INF lib lt  outputDirectory gt                   lt  configuration gt               lt  execution gt           lt  executions gt       lt  plugin gt

So the problem is connected with the metadata errors of elcipse  Go to the metadata folder where this configuration is saved  For me one of the erorrs was that       SEVERE  Error starting static Resources java lang IllegalArgumentException  Document base C  Users Cannibal workspace  metadata  plugins org eclipse wst server core tmp0 wtpwebapps FoodQuantityService does not exist or is not a readable directory   So go there is in the workspace of your eclipse it is different for all and delete all its content   My services was named FoodQuantityService so I deleted all files in org eclipse wst server core but before that delete your server configuration from Eclipse    Then create new configuration File- New- Other- Server select Tomcat and then projects which you want to be published  Start the server and everything will be ok

I do have same problem when i was trying out with first Spring MVC webapp   What i had done was downloaded the jar files given from the link Download spring framework    Among the jars on the zip extracted folder the jar files I was expected to use were    org springframework asm-3 0 1 RELEASE-A jar org springframework beans-3 0 1 RELEASE-A jar org springframework context-3 0 1 RELEASE-A jar org springframework core-3 0 1 RELEASE-A jar org springframework expression-3 0 1 RELEASE-A jar org springframework web servlet-3 0 1 RELEASE-A jar org springframework web-3 0 1 RELEASE-A jar     But as I get the Error  looking out for solution  I figured out that I also need the following jar too    commons-logging-1 0 4 jar jstl-1 2 jar   Then I searched and downloaded the two jar files separately and include them in   WEB-INF lib folder  And finally I was able to get my webapp running using the Tomcat server

I did not have a servlet-api jar in the application s WEB-INF lib directory  or any other jar there    The problem was that in WEB-INF web xml I had this                  lt servlet gt         lt servlet-name gt MyServlet lt  servlet-name gt         lt servlet-class gt com bizooka net MyServlet lt  servlet-class gt       lt  servlet gt       lt servlet-mapping gt         lt servlet-name gt MyServlet lt  servlet-name gt         lt url-pattern gt  MyServlet lt  url-pattern gt       lt  servlet-mapping gt               according to a tutorial   Removing that still allowed the servlet to function  and did not get the error

I had this issue too  and all I did to get rid of it was to delete the existing Server  in my case Tomcat  configurations from project and eclipse workspace  This issue in my case occurred when I played around with my Maven settings and finally screwed them too  But eventually I fixed my Maven issues to realize the tomcat server wont start and failed to load the application context s  of various apps involved in my project  That s when I decided to drop the existing server configurations  I then added the Apache Server once again all over afresh  Then followed with my project specific setting additions  And it finally worked like a charm

If any project that you were using and now closed in workspace might lead to this issue  try deleting context from server folder inside eclipse or open the projects
