Spring – org.springframework.beans.factory.BeanCreationException: Error creating bean with name

I'm having the following error:

I'have already done a lot of research in google and so on, but I can't just get a good answer to my problem, and I've seen a lot more people with the same problem or almost the same.

I already have the necessary jars in the classpath and in the WEB-INF/lib folder (I mean, I do think so)

• antlr-2.7.6
• aspectjweaver
• commons-collections-3.1
• commons-dbcp-1.4
• commons-logging
• commons-pool
• dom4j-1.6.1
• ehcache-1.1
• hibernate3
• hibernate-jpa-2.0-api-1.0.1.Final
• hsqldb
• javassist-3.12.0.GA
• jstl
• jta-1.1
• mysql-connector-java-5.1.11-bin
• slf4j-api-1.6.1
• slf4j-simple-1.6.1
• spring
• spring-test
• spring-webmvc
• standard
• standard-1.0.2

I'm doing the project with Eclipse.

This happens when I start or restart the server.

Solved! Seems it was library conflicts
