java.lang.NoClassDefFoundError: org/springframework/asm/ClassVisitor
Hi,
I'm new to Spring and trying to work through one of the tutorials while using the STS tools (Version: 2.3.0.RELEASE Build Id: 200912171331)
The tutorial in question is this one:
http://static.springsource.org/docs/...C-step-by-step
The tutorial seems to be not quite up-to-date with recent tools and framework releases, so I'm just trying to use STS and latest Spring release and "fill in the gaps" as I go.
I installed STS with tc-server. Rather than use the "build.xml" file in the tutorial I'm running this via the "Run As > Run On Server" and I seem to have gotten this working with just the "index.jsp" page (i.e. no beans used so far).
When I start adding in Spring stuff in the web.xml files I'm running into problems.
Here's what I did:
1) Added a single "Hello" bean as in the tutorial's instructions.
2) Downloaded: spring-framework-3.0.0.RELEASE
3) Put all of its .jar files into the WebContent/WEB-INF/lib/ dir of my dynamic web project. (This seems to add them to my classpath as intended)
I get this error: java.lang.NoClassDefFoundError: org/springframework/asm/ClassVisitor while it is trying to initialize my webapp.
I was guessing that it should be in "org.springframework.asm-sources-3.0.0.RELEASE.jar", but when I look into that .jar file, it appears to be empty (only a META-INF directory is present).
Questions:
1) Am I doing something wrong? (E.g. is downloading and copying them into my lib directory the right way to make STS tools find the spring jars)
2) Where do I get the org.springframework.asm.ClassVisitor class that seems to be needed here.
Thanks for any help with this problem.

Server console output follows below (just in case it might be helpful in diagnosing the problem).
