I have posted your comments on the Struts Wiki. Hopefully this page will be updated as new "gotchas" are found.

I have also found them very helpful.

* jars - I guess its obvious to say you need to replace the jars, but the one people might forget is the new commons-validator.jar for version 1.1.3 of validator. I'm not sure where you can download this from currently, except the Struts 1.2.1 distro includes it.
* tlds - remember to deploy the new versions of the tld files for struts tags. If you don't you won't be able to use the new tag attributes added.
* validator.xml - change the dtd declaration at the top to refer to the dtd for validator 1.1.3
<!DOCTYPE form-validation PUBLIC "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN" "http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd";>
* validator-rules.xml - upgrade to the new version of validator-rules.xml. In the Struts 1.2.1 version the dtd declaration in validator-rules.xml is incorrect - its right in the latest nightly build - either use that or just change the dtd declaration as shown above in the 1.2.1 version of validator-rules.xml.
* struts-config.xml - its not absolutely necessary but you should upgrade to the 1.2 version of the dtd (Note that as well as the version number changing so has the url to struts.apache.org).
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd";>
If you do upgrade to the 1.2 version dtd then there are a couple of attributes which have been removed and you will need to remove them from your struts-config: - debug has been removed from the "controller" element. - dynamic has been removed from the "form-bean" element
Also "contextRelative" in the "forward" element is now considered "deprecated" and a new "module" attribute added.
The only other thing I did was change references to ActionError to ActionMessage - its wasn't necessary to do it, but it got rid of the "deprecation" warnings when I compile.

Subject: Upgrading a Struts 1.1 app to 1.2.1: any 'gotchas' to watch for?
Hi everyone,
After a cursory check of the Wiki & Struts site, I have a question for the collective expertise in the group.
I'd like to leverage all the new features & fixes available in the 1.2.1 release by upgrading my existing app. Here's what we're running now:
Struts/Tiles 1.1 sslext for Struts 1.10 - 4 IBM WebSphere 5.1 JSTL 1.0 (Thanks, IBM ;-)
Has anyone experienced any issues doing such an upgrade?
Thanks in advance for sharing any tribal knowledge,
--Curtis
