Hi all,
I am new to this forum I would like to know the advantage of Spring 2.5.4 over Sptring 1.2. As we are currently using Spring 1.2 version nd wants to upgrade it to Spring 2.5.4.
Please do the needful.

Thanks in advance.

Hi Balkeshwar,

3.0.5.RELEASE is the current production release. If you read the change logs you'll see that so many defects fixes and new features on latest releases.

Using an older version of spring framework will cause incompatibility issues with other spring projects (i.e. Spring security 3 needs spring framework 3).

Hi All,
As our client wants to stick with Tomact 5.0 and JDK 1.5 so using Spring 3.0 for developing the new application and meanwhile also making the other application which are developed in Spring 1.2 and currently in production making them run smoothly would be possible.I mean to say that there could be any issue arising while migrating.
As the code developed with Spring 1.2 is running smoothly with Spring 2.5.So will the same thing would be case with Spring 3.0.

Thanks
