APPLICATION FAILED TO START

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1178)

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:/C:/Program%20Files/Java/jdk1.8.0/jre/lib/ext/servlet-api.jar!/javax/servlet/ServletContext.class
    jar:file:/C:/Users/Mohamed%20Ramadan/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.21/tomcat-embed-core-9.0.21.jar!/javax/servlet/ServletContext.class

It was loaded from the following location:

    file:/C:/Program%20Files/Java/jdk1.8.0/jre/lib/ext/servlet-api.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext

this is first time user spring boot an ihave this error please any one help me to solve this error i am using springv tool suite

  • the error description at the end of the console output should point you towards the issue. It looks like there is something wrong with the classpath of the project. Did you import the project using the `Maven -> Import As Existing Maven Project` wizard, so that the Maven integration of STS/Eclipse takes care of the classpath libs? And how did you configure your JDK that you use to run the project? Maybe there is the servlet-api JAR added manually to the JDK classpath, so that it appears on every launch. – Martin Lippert Jul 30 '19 at 07:20

Try to specify 8+ tomcat version in your POM

<properties>
<tomcat.version>8.0.30</tomcat.version>
</properties>

  • i added this line in pom.xml but this error is appear **org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultValidator' defined in class path resource [org/springframework/boot/autoconfigure/validation/ValidationAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.validation.beanvalidation.LocalValidatorFactoryBean]: Factory method 'defaultValidator' threw exception;* ** – user9213317 Jul 27 '19 at 09:49
  • if you need the validator add: org.hibernate hibernate-validator 6.0.13.Final – M.Saeed Jul 27 '19 at 11:39
  • otherwise exclude it inside your starter web dependency – M.Saeed Jul 27 '19 at 11:39
