Hi, I solved this problem importing the .jar(s) files directly from Eclipse using "import->file system". Obviously before the import operation I deleted by hand the .jar files. After that I modified the application.xml and manifest.mf by hand inserting the correct names for the .jar. This problem is solved now, but I have another one with Datasource. Thanks!
