there is no problem with tomcat    I have suffered 4-5 days to resolve the issue  same issue mentioned above   here i was using tomcat 8 5  Finally  the issue got resolved  the issue was with the  Corrupted jar files   You have to delete all your  m2 repository  for me C  Users Bandham m2 repository   den run  mvn clean install  command from your project folder    happy coding   Give one UP if it is solved your problem

This is usually the problem with web xml descriptor file  May be you have mixed up the annotations and web xml servlet description definitions  Please check the console for more information

This seems like that the servlet api version which you using is older than the xsd you are using in web xml eg 3 0  use this one      http   java sun com xml ns javaee   id  WebApp ID  version  2 5

This is what i have been facing for long time    This happened last time and figured out that one case could be a bad war deployment  which came after i update library maven dependencies on pom and re installed it   SOLUTION    right click on the server  gt   remove the war and  right click on the server again  gt  clean make sure the maven dependencies are added to deployment assembly right click on the project  gt  Run As  gt  maven clean right click on the project again  gt  Run As  gt  maven install  and finally deploy the project on to the server  This helped me to solve the issue

When a servlet 3 0 application starts the container has to scan all the classes for annotations  unless metadata-complete true   Tomcat uses a fork  no additions  just unused code removed  of Apache Commons BCEL to do this scanning  The web app is failing to start because BCEL has come across something it doesn t understand   If the applications runs fine on Tomcat 6  adding metadata-complete  true  in your web xml or declaring your application as a 2 5 application in web xml will stop the annotation scanning   At the moment  this looks like a problem in the class being scanned  However  until we know which class is causing the problem and take a closer look we won t know  I ll need to modify Tomcat to log a more useful error message that names the class in question  You can follow progress on this point at  https   issues apache org bugzilla show bug cgi id 53161

I solved a similar problem by updating the web xml declaration to Servlet 4 0 specification as follows  I use Tomcat 9     lt  xml version  quot 1 0 quot  encoding  quot UTF-8 quot   gt   lt web-app xmlns  quot http   xmlns jcp org xml ns javaee quot        xmlns xsi  quot http   www w3 org 2001 XMLSchema-instance quot        xsi schemaLocation  quot http   xmlns jcp org xml ns javaee                           http   xmlns jcp org xml ns javaee web-app 4 0 xsd quot        version  quot 4 0 quot        metadata-complete  quot true quot  gt         lt  --      your content here      -- gt   lt  web-app gt   You can check which servlet version Tomcat supports by refering to the chart on Tomcat s which version page

I have faced a similar problem  but it consoles the error like an encoding issue  After changing the IDE encoding  it works fine

If you are thinking that previously it was running properly and now on it started showing the particular issue  Then it is just a hit and trial method to solve  so to get better solution you could follow below steps   remove your existing tomcat  if possible remove your project and add your project with a new build add your tomcat server clean the project and refresh the project go for running or debug mode

User · Answer

I have seen this exception while tomcat started and it almost took many hours to figure out the reason  Finally I found out that there were some Spring JARs of a lower version in the lib folder in addition to the Spring jars in the Maven dependencies  The JARs in the lib were automatically added by Eclipse when I added a new Spring Rest controller  I removed those from the lib folder and then let Maven handle the JARs dependancies and it was fine  Bottom line is if the JARS managed by maven and jars in the WEB-INF lib causes a classpath issues  you may encounter this error

create configuration files  servlet xml  and write code for the servlet in the web xml file

for me one case was I just missed to maven update project which caused the same issue  maven update project and try if you see any errors in POM xml

User · Answer

As a generic solution  I recommend that you remove all the secondary dependencies and run the application  if it worked  revert back some  and continue doing the same as long as the application starts  in the end  you will be able to identify which dependency caused the issue   Using the same way  for example  I found that dependencies whose the groupId is  org apache axis2 have caused the issue     lt dependency gt           lt groupId gt org apache axis2 lt  groupId gt           lt artifactId gt axis2-transport-local lt  artifactId gt           lt version gt 1 6 1 lt  version gt    lt  dependency gt    lt dependency gt           lt groupId gt org apache axis2 lt  groupId gt           lt artifactId gt axis2-transport-http lt  artifactId gt           lt version gt 1 6 1 lt  version gt    lt  dependency gt

you can fix it with     lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt servlet-api lt  artifactId gt       lt version gt   servlet-api-version  lt  version gt       lt scope gt provided lt  scope gt   lt  dependency gt      provided solves this problem

Don t panic  You have you copied the servlet code  Ok    WebServlet   HelloWord   public class HelloWorld extends HttpServlet   private static final long serialVersionUID   1L    You gave the same path  WebServlet   HelloWord   for both servlets with different names   If you create a web xml file  then check the classpath
