Hi List, This is my first post to this list ...
I have been chasing some problems when using the optional ant task FTP to access a MVS type host. Part of the problem is the MVSFTPEntryParser.java seems to be only halfway implemented. Here is a updated version of org/apache/commons/net/ftp/parser/MVSFTPEntryParser.java for review, note there is a lot of debug info, and further note, I am not really a java programmer but are willing to learn, so just shoot on whatever is moving ... looking forward to hear your comments. Henrik
