How to solve AbstractMethodError in Hibernate 5?

By Hibernate

I am trying to use hibernate 5 in Java EE in tomcat 7, and I receive this error:

I am using JPA 2.1 and I deleted any old jpa version of the jar.

When I execute the code that throws the exception for the second time , I get a NoDefClassFoundError.

Hibernate seems to start in the log, but it is not creating an entity manager.

How to solve this?

When the jar you use to compile is not compatible with the jar referenced when the server runs the code , Throw AbstractMethodError.

http://docs.oracle.com/javase/7/docs/api/java/lang/AbstractMethodError.html

“When the application Thrown when the program tries to call an abstract method. Normally, the compiler will catch this error; if the definition of some class has changed incompatible since the last time the currently executing method was compiled, this error can only occur at runtime .

This may be due to the version of hibernate-search&. Hibernate Entity Manager

Hibernate search seems to be using hibernate-commons-annotations 4.0.5 final

< p>http://mvnrepository.com/artifact/org.hibernate/hibernate-search-engine/5.3.0.Final

and

Hibernate entity manager seems to be using hibernate -commons-annotation-5.0.0.Final

http://mvnrepository.com/artifact/org.hibernate/hibernate-entitymanager/5.0.1.Final

Check in eclipse Dependency Hierarchy tab of pom.xml to find out which jar version is being used. Used to exclude incompatible versions. Usually this is done automatically by pom. You can also check WEB-INF/lib folder to see what is being downloaded jar file.

I also see that you are using this jar. If you use tomcat 7 better use it and make its scope “provided” because the web application references the tomcat servlet api jar at runtime .

When the jar you use for compilation is incompatible with the jar referenced when the server runs the code, an AbstractMethodError is thrown.

http://docs.oracle.com/javase/7/docs/api/java/lang/AbstractMethodError.html

“Thrown when an application tries to call an abstract method. Normally, compile This error will be caught by the browser; if incompatible changes have occurred in the definition of certain classes since the last time the currently executing method was compiled, this error can only occur at runtime.

This may be due to hibernate-search& hibernate entity manager
