问题
I need help with an error which make me crazy.
I started to study Java EE and I am going through tutorial on youtube. Everything went well till I came to Spring, Hibernate, JSF preparing project.
I added dependencies to my pom.xml project like you can see below, but in my config files I am having an error:
"Build path is incomplete can't find class file for org/aspectj/weaver/BCException"
I was looking on google and also here for an answer answer to my question. I found that I need to add aspectj dependency, but still it doesn't work and I am having the same error.
I included following libaries to my project: (So I guess its not a problem with missing libary)
My pom.xml file:

And here you can see one of the files which contains an error: ( I deleted xml declaration and added comments in the place when an error occurred)

I would really appreciate your help.
Benzonico I checked in my classes, if BCExcepction is visible, seems it is. Also I added externals jars aspectj and xwork and it still doesn't work.
The problem is weird imo, since on the explorer tab on the left side of the eclipse, when you check you will find that there is no error placed in the class name. Now in the center of the eclipse where code is placed you can see, that problem occurs.
Still I need help with this question. Anyone?
回答1:
This does not address directly your problem but will help you to figure it out :
You can do two things to check that your missing class is on the classpath of your project :
In Eclipse : press ctrl+shift+t and type the name of your class, if it does not show up then it is not in your class path.
You can also check in which jar is your class using findjar and verify that this jar is on your classpath somewhere.
回答2:
Sometimes, the order of importing your libraries is important, try to make your app load the library earlier. if your using eclipse, check in build path configuration, order of import.
