Question

I am new to spring development and I tried to add maven dependency for spring orm, in the pom.xml file it gives the following exception when the server starts. Also when I remove that dependency, the exception goes. Can you please tell me what is wrong with this.

Thanks.

Looks like something is wrong with the jar file. — Delete it from your local m2. repository and maven will download it again. I hope this fixes the problem.
