Error 500: Filter [Spring OpenEntityManagerInViewFilter]: could not be loaded
spring, spring-mvc
Solution
The "Unsupported major.minor version" errors are caused by your using JAR files compiled for a higher version of java than you're running.
I think class file version 49.0 is Java 5, and you're running 1.4. That means you must be using a library that's Java 5 only, and the only version of Spring thats java 5 only is Spring 3.0. If that's the case, then downgrade your Spring to 2.5.6.
Problem
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: org/springframework/orm/jpa/support/OpenEntityManagerInViewFilter (Unsupported major.minor version 49.0) 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: Error 500: Filter [Spring OpenEntityManagerInViewFilter]: could not be loaded Can you please guide me ,where exactly I am doing wrong. Attached is my Web.xml.
