Oracle Forms

Hi All

I was wondering if someone can help me with the following problem.

I'm trying to download a file from custom table, but I'm getting an error:

http://127.0.0.1:8081/apex/HELP%20DESK.download_my_file?p_file=2780601060015956

Bad Request
The HTTP client sent a request that this server could not understand.

If I use OHR schema I was able to download files without any problem.

Something cought my eye, my schema named as HELP DESK, and there is a space between two words, as you can see in URL.

I'm getting this error because of the space in the schema or something else is wrong?

Example I was using from the following URL:
http://download.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm


I spent good 4 hours for this and I still cannot get to work

Please help

Any ideas are very welcome

Thanks in advance
