"Failed to load ApplicationContext" when using repository data access layer

[britter]

Hi,

I'm trying to build up a small app using roo. Here is the roo script:

perform eclipse

When I imported the project to eclipse I ran into problems: roo (1.2.0.RELEASE [rev 39eb957]) generated an incompartible applicationContext-jpa.xml. It seems that spring-data-jpa-1.0.2 is not compartible to spring-core-3.1.0. Eclipse will show you some strange XSD validation errors. So I modified my pom.xml to use Spring 3.0.0 and everything seemed to work fine. But when I run perform tests on my project nothing seems to work and I do not have a clue why. I'm getting "Failed to laod ApplicationContext" on 54 of 55 tests.

I checked the AspectJ test configuration and it configures the applicationContext correctly:

@ContextConfiguration(locations = "classpath:/META-INF/spring/applicationContext*.xml");

Does anybody have an idea what I am missing?

Regards
Benedikt

Are you using STS or regular Eclipse? So far I've only had luck getting my projects to work properly in STS so would recommend using that instead, at least in the beginning to get things going.

I'm kind of using STS. In fact I downloaded eclipse 3.7.1 and installed STS features from the marketplace. Unfortunately the STS feature installed a version AJDT that was incompartible to eclipse Indigo. So I had to manually remove AJDT and reinstall the correct version. But that is just a side info :-)

I have re-startet my project using plain spring, because I couldn't get roo to work and I ran into similar problems. But this time I was able to fix those, because they were not hidden in the depth of generated aspects. I can not recall every single problem and the solution, but as far as I can tell you have to be very cautions that your framework versions will work together. For example hibernate-jpa-3.5.4-Final will NOT work with spring release 3.0.0 (you will get some AbstractMethodError). You will have to use release 3.0.1.

For those how are quite new to spring and are facing similar problems I can just recommend to look at the root cause of your exception (don't get confused by "Failed to load ApplicationContext"). If you will see NoClassDefFound oder AbstractMethod execptions, try to search your workspace for the mentioned classes. It is likely, that you are using incompartible libraries.
