Subject Re: Security restrictions for Tomcat
Date Wed, 26 Sep 2007 17:41:06 GMT
I am confused now
web.xml instructs Tomcat what application needs to be called for a given
MIME type
for example:
- <mime-mapping>

 Tomcat pass the request to the  third party application based on the MIME
type, so if I show the link to the .RTF file and the user selects the link,
the Microsoft Word will display the selected file.  The same with PDF files
- the  the ADOBE reader is invoked
My undesraning is that by writing file bytes to the servlet output, I am
just creating and HTML file where the file content is a body of the HTML

But if I output the bytes of the file to the servlet output, it will look
the same way as I would open RTF file in the notepad - with all controll
characters inside.
Unless I am missing something here...

As far as directory listing - yes, I do see the directory listing for all
folders that are underneath of my application except WEB-INF and I didn't do
any special set up for that - I am using all default XMLs except the
web.xmlwhere I am defining my servlets.

I appreciate your help.
