Java Servlet exception

Question

I try to start the server using servlet but I get a java exception

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
    at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:60)

It says that the {60 is not a valid line number in org.apache.catalina.startup.Bootstrap}

in bootstrap.class in a class file editor, it shows that: the source attachment does not contain the source for the file Bootstrap.class. can I get any help, please?

This looks like a duplicate, take a look at this answer for additional help. Basically you need need to check that you have the tomcat-juli.jar file on the classpath. If you don't see it in the Tomcat lib dir, you can add it.

For maven add it as a runtime dependency:

<dependency>
  <groupId>org.apache.tomcat</groupId>
  <artifactId>tomcat-util</artifactId>
  <version><!-- version from tomcat-embed-core --></version>
  <scope>runtime</scope>
</dependency>
