What are you, people? On dope?

I’m really interested in seeing the Grails and Groovy work that has been including in STS 2.2.1. I followed the instructions here: http://blog.springsource.com/2009/06/24/installing-sts-into-eclipse-35/, but unfortunately I got stuck at step 6. It kept asking for a mylyn feature group 3.3.0I20091013,3.4.0.

Ugh!

No doubt installing it now has caused the instructions to go out of date.  Fortunately at http://www.eclipse.org/mylyn/downloads/ there were a bunch of weekly updates.  After adding the weekly update sites to eclipse:

http://download.eclipse.org/tools/mylyn/update/weekly/e3.4  and http://download.eclipse.org/tools/mylyn/update/weekly/extras

This enabled me to install STS.

UPDATE

If you want to install STS on Eclipse.  Visit this page:  http://www.springsource.com/products/eclipse-downloads.  It will give you a current version of Eclipse 3.5.1.  Run Update on it, then install the STS link update.

Roo looks like it aims to eliminate/reduce some of the complexity with the setup of an Java application. I tried my hand at the vote and petclinic application by following the instruction in the readme. I ran into a problem with deploying the app to my local tomcat 6 instance. Roo uses the Hibernate EntityManager, but for some reason, I’m getting these errors.  I would have thought that this example would have worked right out of the chute.

I found that from http://forum.springsource.org/forumdisplay.php?f=67 I could run mvn package and get it to run correctly under Tomcat.  It appears to be a problem with the AspectJWeaving.
