Question

We are using very old version of spring 2.0.6 in our code, We were trying to upgrade it to the latest 3.1.1.RELEASE, But facing issues.

First, The latest version of spring artifacts mentioned below are 2.0.8:
spring-jmx
spring-dao
spring-support

Where are these in new SPRING?

Second, Somehow, it seems that our code is not compatible with these 3 artifacts:
spring-beans -3.1.1
spring-jdbc -3.1.1
spring-context -3.1.1

What are the changes in these latest versions compared to old version (2.5.6)?

Answer 1

I strongly recommend to do it step by step:

• upgrad to Spring 2.5
• then to Spring 3.0 (the most changed)
• and then to 3.1

in Spring 3.0 are some libary changes. But I think you will find some stack overflow question on how to upgrad from 2.5 to 3.0.
