Issue
When i run the STS(SpringBoot) application i get the below error:
The attempt was made from the following location: org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1321)
The following method did not exist:
javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;
The method's class, javax.servlet.ServletContext, is available from the following locations:
jar:file:/home/talha/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
jar:file:/home/talha/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.33/tomcat-embed-core-9.0.33.jar!/javax/servlet/ServletContext.class
It was loaded from the following location:
file:/home/talha/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar
The suggestion in the ide is: Action:
Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext
I guess there is something wrong with my pom.xml the code is as below:

I get the error only after adding the above dependencies, the need to add the dependencies is the below class:

Please help me resolve this issue. Thanks in advance
Solution
getVirtualServerName() was added in Servlet 3.1, but you included servlet-api-2.5.jar is your application.
Options:
Change your dependencies to include
servlet-api-3.1.jar(or later)Remove the
servlet-api-2.5.jardependency, since the correct version is included in the Embedded Tomcat file (tomcat-embed-core-9.0.33.jar).
Actually, you should never ship servlet-api.jar with your application, since it will be provided by the Servlet Container. Seems you're missing <scope>provided</scope> in your dependency tag for the servlet-api file.
