just registered, so sorry if the topic is wrong in "Spring", wasn't sure, its kind of basis Eclipse Stuff i guess.
I have a simple and working Spring Project with an Aspect, an ApplicationContext, javaagent is declared and i have a META-INF/aop.xml File. The Program runs, the context works well, but the Weaving won't take place. The Weaver only reacts when I put the META-INF\ Folder directly into the bin\ Folder in my Workspace. Of course that works for a moment, until Eclipse deletes it in the build process. I have been trying around with some Classpath and Buildpath Setups in Eclipse, but i have no Idea. Another way was just putting the aop.xml into a .jar File named "META-INF" and add it as external jar, that worked too, but that looks pretty stupid.
Welcome to CodeRanch! The IDEs forum is the best place. I've added it there for you.
It looks like the META-INF folder is in the root of your project in the screenshot. It should be in the src folder. That way when Eclipse rebuilds, it automatically gets copied from src/META-INF to bin/META-INF.
I would encourage you to use a tool like maven. The simple archetype will set up your java jar application in the correct fashion. META-INF does not need to be a src folder as is depicted in your image.
