Mime types Glassfish + JBoss
Adapted from https://github.com/cappuccino/cappuccino/wiki/Server-Side-Issues
You need to have the mime type of file types it doesn’t understand set to something for Cappuccino to work. Specifically, you should set the following mime-type/extension pairs. This can be done in the web.xml:
1 <mime-mapping>
2 <extension>j</extension>
3 <mime-type>text/javascript</mime-type>
4 </mime-mapping>
5 <mime-mapping>
6 <extension>plist</extension>
7 <mime-type>text/xml</mime-type>
8 </mime-mapping>
9 <mime-mapping>
10 <extension>sj</extension>
11 <mime-type>text/javascript</mime-type>
12 </mime-mapping>
