== 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''':

{{{#!highlight xml
<mime-mapping>
     <extension>j</extension>
     <mime-type>text/javascript</mime-type>
</mime-mapping>
<mime-mapping>
     <extension>plist</extension>
     <mime-type>text/xml</mime-type>
</mime-mapping>
<mime-mapping>
      <extension>sj</extension>
      <mime-type>text/javascript</mime-type>
</mime-mapping>
}}}

== Download file ==

{{{#!highlight objectivej
    DownloadIFrame = document.createElement("iframe");
    DownloadIFrame.style.position = "absolute";
    DownloadIFrame.style.top    = "-100px";
    DownloadIFrame.style.left   = "-100px";
    DownloadIFrame.style.height = "0px";
    DownloadIFrame.style.width  = "0px";
    document.body.appendChild(DownloadIFrame);
    //....
    DownloadIFrame.src = "http://localhost:3000/uploads/fileXpto";

== Index of string ==
{{{#!highlight objectivej
var idx = [data rangeOfString:@"str xyz"];
