org.apache.oro.text.regex does not exist

I have created my code inNetBeans 5.0. I have includedorg package inisidescr folder. I am getting the following errors, eventhough the errors mentioned are contained inside myorg package.

I am getting 24 errors and 2 warnings

D:\Mail\src\org\apache\commons\net\ftp\parser\RegexFTPFileEntryParserImpl.java:19: package org.apache.oro.text.regex does not exist

import org.apache.oro.text.regex.MalformedPatternException;

D:\Mail\src\org\apache\commons\net\ftp\parser\RegexFTPFileEntryParserImpl.java:20: package org.apache.oro.text.regex does not exist

import org.apache.oro.text.regex.MatchResult;

.

.

Please tell me why am I getting these errors? Is my org package to be placed elsewhere?
