I am with a problem in my application.
It obtains data from websites through Crawler4j and it needs to create some directories and files to manipulate data, but tomcat doesn't give permissions. The answer is like that:
Couldn't create this folder: /data/crawl/root
How to configure tomcat to give permission for external jars to create directories and files in my application?

Thanks for all.
I've found an answer.
It was because a dash in the beginning and it tries to create a directory in the beginning of the system and the user doesn't have permission to that.
I've already changed the folder and all is working.
