title: which jar contains org.springframework.util.MultiValueMap in spring2.5?
body: <p>I am using spring2.5. and trying to implement a custom CommonsMultipartResolver for ajax upload.</p>
  
  <p>After I submited form, I got following error:</p>
  
  <p>org.springframework.web.util.NestedServletExceptio n: Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.web.multipart.commons.CommonsF ileUploadSupport$MultipartParsingResult.getMultipa rtFiles()Lorg/springframework/util/MultiValueMap;</p>
  
  <p>It seems that I need class org.springframework.util.MultiValueMap. But I can not find it anywhere in spring2.5.</p>
  
  <p>Can you tell me which jar contains it?</p>
  
  <p>thanks </p>
