LAB-4939: Spring 3 Annotation-based DI, Exercise 3

[Vance]

I'm having trouble getting Exercise 3 for LAB-4939 to work. Here's the
output I get when I try to run the 'di_configuration_XML' project:


log4j:WARN No appenders could be found for logger
(org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
accountRepository.findById("A123").getBalance() = 1000.0
accountRepository.findById("C456").getBalance() = 0.0

Ok, I fixed that problem by going to www.findjar.com Web site and
downloading and adding the following JAR file:

org.apache.servicemix.bundles.hamcrest-1.2-dev1_1.jar

Now when I try to run the app, I get the following stack trace
complaining about a missing JUnit class:

log4j:WARN No appenders could be found for logger
(org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
accountRepository.findById("A123").getBalance() = 1000.0
accountRepository.findById("C456").getBalance() = 0.0

I went to findjar.com again, and found out that the 'org.junit.Assert'
class is part of the following JAR files:

[CLASS] junit-4.1.jar.org.junit.Assert
[CLASS] junit-4.4.jar.org.junit.Assert

My project is using junit-4.7.jar for some reason.

Actually that 'Assert' class should be part of junit-4.7.jar...

I can't get the 'di_Configuration_Java' project discussed in Exercise
4 to work, either. I've gotten the same error messages as I did for
the Exercise 3 project.

Ok, I've got the 'di_Configuration_Java' project to work. I ended up
doing the following (and this approach also works for the
'di_Configuration_XML' project):

1) Create a 'lib' directory within the project
2) Copy the 'junit-4.7.jar' file to this directory
3) Update the project properties so this JAR file (along with the
'hamcrest' JAR file) is added to the 'Libraries' tabpage of the 'Java
Build Path' page of the project properties window
4) Clean and rebuild the project
5) Run the 'main()' method of the 'Main.java' class

Thanks. In theory, the pom.xml should take care of all this. For the
sake of this exercise,
I removed the dependency on hamcrest. New lab zip file has been uploaded.
