title: Need Spring version# - only have spring.jar file
body: <p>I've inherited an app that uses Spring. The original developers are not available. The Spring jar file is just "spring.jar", so there's no version# in the filename to help me. I'd like to download the Spring source corresponding to the jar file. The MANIFEST.MF file has "Spring-Version: 1.2" however that's not precise enough. I've looked at version 1.2.1 and 1.2.9 and it doesn't match up quite right. The key thing is that <code>org.springframework.web.servlet.view.AbstractCachingViewResolver</code> has a <code>prepareView</code> method which is called from <code>resolveViewName</code> and it does not seem to be in 1.2.1 or 1.2.9.</p>
  
  <p>Is there any easy way to track down the right version?</p>
