Resolving java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract.. error

I was trying out the code available here – ‘Getting started with Spring MVC’ (http://blog.springsource.com/2011/01/04/green-beans-getting-started-with-spring-mvc/) – today and was facing an irritating error (see below) everytime when I deployed the code. Finally, found the reason and fixed the issue.

Reason

I included this dependency in my project, unaware of the fact that it’s just the api and the implementation should be provided by the application server/web container. We need to remove this jar from classpath to solve this error. But this might be required during compilation. Hence, I modified the maven scope to provided, and that way, the JAR was not copied to the generated app WAR , thereby solving my problem.

<dependency>
 <groupId>javax</groupId>
 <artifactId>javaee-api</artifactId>
 <version>6.0</version>
 <scope>provided</scope>
 </dependency>
