Java Development Tools

Hello Experts,

I'm quite sure that in this forum there are analogous issues, but I haven't been able to find one who matches.

The IDE used is JDeveloper 11.1.1.5.0.

The issue: I created some custom classes and I deployed inside an archive1.jar.
I generate a new testing code, "Test.java" and, from JDeveloper, I'm able to import the above library, invoke it and I'm correctly able to use the methods present inside my custom classes.
I generate a deployment profile, I edit it and inside the "File Groups" I add:

"WEB-INF/lib" as target directory and group file name.

I make sure that inside the voice "filters" is present the previous jar that I imported inside this project and I deploy.

Running from console I get the following error:

C:\>java -jar mainClass.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/MyList
at com.test.main(test.java:7)
Caused by: java.lang.ClassNotFoundException: com.MyList

I opened the mainClass.jar file and I checked that inside the folder WEB-INF/lib is correctly present the mylist.jar file, although it says that it's not able to find it inside the jar file.

How could I fix this problem?

Thank you
