I just wrote a few codes today, although I found it in the project, I have improved it through my revision.
1 Sendmail - The sender of the greeting card for the project is originally here: http://www.9cbs.net/develop/read_article.asp? ID = 14929 This code has modified some implementations. You can increase any attachment, which can support HTML. If you do not consider the set title, whether the content is reasonable, etc., the JavaMail and Jaf package are used, and you need to download additional download from http://java.sun.com, and use my own Logger class, you can modify it according to your situation
2 ftpConnection - Download Management in the project provides simple features such as FTP browsing, lists, due to the limitations of the B / S architecture that cannot be used. Only applicable to administrator single users use the web way to access the FTP and upload the meaning of the download, only the browsing function is to get the file name from the FTP and join the database to provide the Database to provide the FTPCLIENT class with SUN. achieve. This type of function is extremely weak .... In Servu server test, by improvement: If you want to make more people to use, you can consider adding its instance to session.
