I have been deep into configuring a development ecosystem with my client lately, with a boring session of integration tests for another project going in parallel, so I wanted to try something different for a change.
Eclipse 3.5 is about to come out and I have been playing with the RCs for a while. I’m on a Mac, so one of the things I wanted to see the new support for Cocoa (so far works great, but I have not been able to use Java 6 or 64bits). The other one was updating Eclipse IAM to run on the new Eclipse.
Creating a Lift project
Step one is creating the project from the lift archetype.
After all dependencies are downloaded I was welcome with some build errors on the test cases, which seem to be caused by Lift’s open dependency on Jetty (there were some refactorings in Jetty 7).
Setting an upper bound of 7.0.0 for the jetty dependency fixed those.
<dependency> <groupid>org.mortbay.jetty</groupid> <artifactid>jetty</artifactid> <version>[6.1.6,7.0.0)</version> <scope>test</scope> </dependency>
Clean the project and the errors are gone.
Running the project
Starting with Lift, suggests running the project launching jetty from maven. I wanted to use WTP instead, so I tried to install the Jetty adapter by using the support in WTP for downloadable adaptors. Unfortunately, the installation did not work, so I used the built-in support for Tomcat 5.5 instead.
Before getting into the next chapter of Starting with Lift, I played around with the application I had just built.
- Changes to index.html were shown immediatly
- Same thing when modifying the default.html template
- Modifying the HelloWorld class to return a new value causes the context to be reloaded and the changes can be seen live (no redeployment needed)
- Adding a second method to HelloWorld and using it on the index.html template works as above (as expected)
End of chapter one
There might be some surprises down the road, but the initial impression has been good.
- IAM has "just worked" and stayed out of the way in a non-java project (there is no special support on IAM for Scala or Lift, although esmi is on the works)
- WTP performed well. I expect the issues with the installation of the Jetty adapter to go away soon, since Jetty has joined Eclipse.
- About Lift and Scala... well, I have a lot of things to learn yet.
I am looking forward to keep using these tools together (at least go through the Starting with Lift guide!).
