Method Detail

getContentType

public static java.lang.String getContentType(java.io.File file)

Returns the content type from the file.

Parameters:

file - the file of the content

Returns:

the content type if it is a supported format or "application/octet-stream" if it is an unsupported format

getContentType

public static java.lang.String getContentType(java.io.File file,
                                              java.lang.String fileName)

Returns the content type from the file and file name.

Parameters:

file - the file of the content (optionally null)

fileName - the full name or extension of the file (e.g., "Test.doc", ".doc")

the content type if it is a supported format or "application/octet-stream" if it is an unsupported format

getContentType

public static java.lang.String getContentType(java.io.InputStream inputStream,
