ckeditor on tomcat and roxy filemanager in apache

Hello,

I have a Java web application hosted on a tomcat running on port 8080. There I have a ckeditor and I'm trying to grab images stored in apache running in the same machine but in port 80. But I get the following error:

Error: Permission denied to access property 'CKEDITOR'

Is there any configuration do I need to change in order to make this work.

Thanks a lot
