Mime-Type are used to provide identifiers for file formats on the Internet.

By default, XAP files are not recognized as a Silverlight application in Tomcat or IIS 5.1. You can set a Mime-Type to identify XAP files on both servers.

Setting Mime-Type in Tomcat

in %TOMCAT_INSTALL%/conf directory, edit web.xml file. Add the following description to identify XAP files

<mime-mapping>
    <extension>xap</extension>
    <mime-type>application/x-silverlight-2-b2</mime-type>
</mime-mapping>
  • Restart Tomcat and clear your navigator cache,
  • get a XAP file to ensure that the Mime-Type is correctly set
