title: Error 500: Filter [Spring OpenEntityManagerInViewFilter]: could not be loaded
body: <p>I am trying to deploy a Spring application on WAS 6.0 (JDK 1.4.2). Day back I was getting tons of (Unsupported major.minor version 49.0) errors. I replaced most of the jar files and now I am left with only one error on:</p>
  
  <p>org/springframework/orm/jpa/support/OpenEntityManagerInViewFilter (Unsupported major.minor version 49.0)</p>
  
  <p>what jar file do I need to replace for this? Also when I am running my URL in the browser I am getting the error:</p>
  
  <p>Error 500: Filter [Spring OpenEntityManagerInViewFilter]: could not be loaded </p>
  
  <p>Can you please guide me ,where exactly I am doing wrong. Attached is my Web.xml.</p>
  
  <p>Your help is highly appreciated.</p>
