We had a Problem with JBoss Seam 2.2.1.CR1 Logger. We were not able to log with parameters. (This is a known bug: https://jira.jboss.org/browse/JBSEAM-4606 )

I was looking for a tutorial which covers upgrading Seam, but I did not find any. So this is my solution how to upgrade from Seam 2.2.1.CR1 to Seam 2.2.1.CR2:

It is kind of a trivial job, because in normal case you just have to replace libraries. Here is a step to step tutorial:

Download Seam 2.2.1.CR2 Version from Sourceforge

Copy all files from the /lib folder (without the subfolders „interop“ und „gen“) in your projects /lib folder.

Edit the files „deployed-jars-ear.list“ and „deployed-jars-war.list“ and add the entries:jaxrs-api.jar
resteasy-jaxrs.jar

If you are lucky, you can ignore step 3. In our project we had an issue with resteasy, because in CR2 you have to deploy the two .jar files.
