Spring + Hibernate + Tomcat Dependency problems

Question

when I run tomcat and the war is deployed I get : NoClassDefFoundError : org/apache/commons/collections/map/LRUMap

 Invocation of init method failed; nested exception is
 java.lang.NoClassDefFoundError:
 org/apache/commons/collections/map/LRUMap
 at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:527)
 ~[spring-beans-3.1.0.RELEASE.jar:3.1.0.RELEASE]

What is strange is that I got the commons-collections-2.1.jar (I even tried 3.1) in my WEB-INF lib folder.

Edit : I did copy the commons-collections from WEB-INF/lib to Tomcat lib and it seems to work. However I won't be able to do that on the production server, why isn't it taking my WEB-INF/lib version ?

Answer 1

Ok so I did put version 3.2.1 of commons-collections and the error disappeared. I unfortunately still don't know which library is depending on this version. Even mvn dependency:tree didn't help ...

Answer 2

I had this exception when I was with xdoclet on dependencies.

If you are with this dependency, just exclude it.

Answer 3

I have the same probleme, maybe it's too late to approve the answer but it's still benefitial for people who will have this problem in the futur. So I exclude commons-collections from net.sf.jasperreports, after that the tomcat runs perfectly whithout any problem.

<dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>4.1.1</version>
    <type>jar</type>
    <scope>compile</scope>
    <exclusions>
        <exclusion>
            <artifactId>commons-collections</artifactId>
            <groupId>commons-collections</groupId>
        </exclusion>
    </exclusions>
</dependency>
