NOTE: Starting from 7.5, MedDream is effectively Java-only and contains an embedded web server – Apache is no more needed.

Supported operating systems

MedDream supports the following operating systems:

  • Windows Server 2008 (32 bit and 64 bit) and newer;
  • Windows 7 (32 and 64 bit) and newer;
  • Linux (32 bit and 64 bit).

Supported PHP scripting interpreters

Since 7.5.1 MedDream does not need PHP by itself. However PacsOne does, and MedDream provides a file applet.php for integration into its web interface.

This module requires the cURL extension and is regularly tested under PHP 5.4 . . . 7.1 (newer ones might also work).

Supported Java runtime

Only Java 8 is supported and was tested.

  • We recommend OpenJDK 8. The entire JDK is not needed, a JRE is sufficient. Builds for Windows are harder but still possible to obtain;
  • Java 8 from Oracle is the traditional choice but less affordable as of now.
