Separate database configuration - mysql

Question

I've been dealing with this problem for couple of days now and I can't get around to solve it. The working setup that I need is: two separate databases, one for JUnit testing and the other for the pure application access purposes.
I've been using MySQL for the the application part, since I need the full control and support and the other database that I am considering is Derby or H2 since the speed is essential here.
Okay, the MySQL database is working as it should, the JUnit tests are 100% success when I run them through
and there are no problems there. However, when I try to configure my project with the second database, the
problems arise. I've been searching for answers and I found the following setup when adding additional database to your spring-roo project:
Additional ApplicationContext that I've put in: src/test/resources/META-INF/spring/ and named as: applicationContextTest.xml
As well as additional ApplicationContextSecurity file that I've created in the same folder and named applicationContext-securityTest.xml
Necessary changes in pom.xml, persistence.xml and web.xml files
And also I've configured #ApplicationContext in JUnit test class to use appropriate files
Also separate database_test.properties located in the same folder as mentioned above
The exception that I am constantly getting is that the EntityManager has not been injected. I know this is a scarce information to work on, but I just want to get few opinions before, lets say, posting the whole code and the files that go along so that you people can see if I have made some silly mistakes(which at this point I am sure I haven't) or that I am missing some additional changes that need to be made.
The configuration I am using is: latest spring roo, maven and eclipse 4.2.2
Here is the stack trace that I get for the exception:
java.lang.IllegalStateException: Entity manager has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?)

Answer 1

I have experienced this problem before.
I have written a blog article on how to achieve this setup:

Answer 2

I had this problem when the environment in which I executed the roo project could not load AspectJ for some reason.
Specifically, it occurred to me when:
The pom.xml in eclipse give errors on the aspectj dependencies (M2E plugin execution not covered error). Solution was to do a quick fix on the error, ignore plugin goal, then set it as execute on preferences, as explained here http://wiki.eclipse.org/M2E_plugin_execution_not_covered.
I was running the Roo project on Jetty version 8. Solution was to switch to version 9.
It maybe not your case but I hope will help others!
