Examples of org.exist.util.MimeTable

org.exist.util.MimeTable
Global table of mime types. This singleton class maintains a list of mime types known to the system. It is used to look up the mime type for a specific file extension and to check if a file is an XML or binary resource. The mime type table is read from a file "mime-types.xml", which should reside in the directory identified in the exist home directory. If no such file is found, the class tries to load the default map from the org.exist.util package via the class loader. @author wolf
