All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class AttachmentServlet

extends javax.servlet.http.HttpServlet

This is a simple file upload servlet customized for JSPWiki. It receives a mime/multipart POST message, as sent by an Attachment page, stores it temporarily, figures out what WikiName to use to store it, checks for previously existing versions.

This servlet does not worry about authentication; we leave that to the container, or a previous servlet that chains to us.

Since:

1.9.45.

Grabs mime/multipart data and stores it into the temporary area. Uses other parameters to determine which name to store as.

The input to this servlet is generated by an HTML FORM with two parts. The first, named 'wikiname', is the WikiName identifier for the attachment. The second, named 'content', is the binary content of the file.

After handling, the request is forwarded to m_resultPage.

Overrides:

doPost in class javax.servlet.http.HttpServlet
