Problem
In Hibernate development, it hits…
java.lang.ClassNotFoundException: org.objectweb.asm.Type
Solution
This is caused by the missing of asm.jar, you can get it from asm official website, or get it via Maven
<dependency>
<groupId>asm</groupId>
<artifactId>asm</artifactId>
<version>3.3.1</version>
</dependency>
Hi Mkyong,
You always save our time 🙂
I had the same issue with a jax-rs (cxf | jsr311-api) application deployed in wso2 application server, and adding this dependency solve my problem.
Thank you verymuch.
