problem with upload

i have the same problem in the FCKeditor included with BP BLOG... any solutions? could it be permissions?

Hi,
I have a problem with uploading file and also with filemanager.
1. I deployed fckeditor.java demo war on WebSphere application server. Everything works perfect.
2. When I deployed this same war on WebSphere portal server, this error appeared after clicking on choose on server (in image window):

Please do you have any suggestion where should be problem. Thank you very much.

Too lazy to read the stack trace? It says the exaclt reason why it's failing.

Yes, you are right.
I thought that it must see the constant if it is defined in library and looked for the mistake elsewhere.
I don't know why because DirectoryFileFilter.DIRECTORY is not depricated and should be used in older java versions, but when I changed it to DirectoryFileFilter.INSTANCE it runs well.
So thank you.
