Spring Batch Admin Sample war overlay - tomcat error

[jtroxel]

I decided to try the approach of creating a maven war project using spring-batch-admin-sample as a war dependency, in other words making my project a thin war-overlay. The pom has the following:

    <dependency>
      <artifactId>spring-batch-admin-sample</artifactId>
      <groupId>org.springframework.batch</groupId>
      <version>1.0.0.RELEASE</version>
      <type>war</type>
    </dependency>

This builds OK, but when I try to start the war in tomcat, I see the following in catalina.out:

org.springframework.beans.factory.parsing.BeanDefi nitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath*:/META-INF/spring/batch/bootstrap/**/*.xml]

NoSuchMethodError usually comes from having the wrong version of the class on the classpath. I don't know much about war overlays, but it sounds like you could build a war with two versions or the wrong version of Spring quite easily.
