Any java/servlet/string function where we can find out the mimeType of a file in AEM

Hi All,

It's something we are seeing up for restricting certain file types in 6.2.

You can use Apache Sling - MIME Type Support (commons.mime and commons.contentdetection) in AEM.

To access asset's mimetype, use the API Asset (Adobe CQ 5.6.1 Java Documentation 5.6.1 API)

-> I wanted a java/servlet function which extracts the mimeType of a file that we are putting for upload

AEM Assets already extracts Mimetype and persist under asset's metadata:

/content/dam/test.jpg/jcr:content/metadata/dam:MIMEtype

In Servlet, you could use the service as I have mentioned[0] to detect mime type from an input stream of the file (sourced by TIKA library).
