This page describes how to install Weasis.

Weasis is launched from the dcm4chee administrative web interface, as shown in the pictures below. It may also be copied to a CD (or other removable device) with images.

For dcm4chee-arc4 (alpha version)

dcm4chee-arc4 does not have a web interface yet. However Weasis can be launched via weasis-pacs-connector, see configuration of weasis-pacs-connector for dcm4chee-arc.

For dcm4chee-web3 (recommended stable version)

  • Install dcm4chee, if not already done.
    • dcm4chee-web3 is not compatible with versions of dcm4chee before 2.16.0
    • dcm4chee 2.16.0 to 2.17.0 are compatible with dcm4chee-web3, but the older dcm4chee-web is installed by default.
    • For dcm4chee 2.17.1+, dcm4chee-web3 is already installed.

      To check if it is the latest version, start dcm4chee-web3 (http://localhost:8080/dcm4chee-web3/), log in, and mouse over the icon in the upper right corner.

  • Go here and download these Weasis files.
    • From the folder with the latest version number:
      • weasis.war
      • weasis-i18n.war - Optional for internationalization (translation)
    • From weasis-pacs-connector folder:
      • dcm4chee-web-weasis.jar
      • weasis-pacs-connector.war

        Download issue

        Some browsers (Internet Explorer) may rename war files to zip. If so, use the Save As option when downloading. Change the name back to war.

  • Place these files in the dcm4chee deploy folder (server/default/deploy/).
  • To activate Weasis, go to the JMX console (at http://localhost:8080/jmx-console)
    • In dcm4chee.web select service=WebConfig and set these two values:

      WebviewerNames = weasis
      WebviewerBaseUrl = NONE

      From weasis-pacs-connector 5.0 WebviewerBaseUrl can have different values:

      • Launch Weasis as an external application (default value when NONE): WebviewerBaseUrl = weasis:/weasis-pacs-connector/viewer
      • Launch Weasis as an Applet in the web browser (not recommended as several browsers block Java plugin) : WebviewerBaseUrl = weasis:/weasis-pacs-connector/viewer-applet
    • Click the Apply Changes button
  • Configure Weasis (This step is optional if you just want to keep the default configuration. It is required when the AE Title DCM4CHEE has been changed)
    The default configuration of Weasis is stored in two files inside weasis.war.
    To override the default configuration:
    • Go here.
      weasis-pacs-connector 4.x and 5.x: Download and rename it

      weasis-pacs-connector 6.x and superior: Download the current and rename it, and download

      Download issue

      From github interface, click on "raw" button for downloading the file with the "save as..." menu of the browser.

    • Copy the files into a folder in the classpath of the servlet container. In JBoss (inferior to version 7), the best location would typically be server/default/conf.
    • Edit the configuration as needed.
      For example, dcm4chee may be running on a different computer than Weasis, or the AE Title of dcm4chee may have been changed.
      If so, edit Change, pacs.port, and pacs.aet.
    • To add new properties or arguments in the JNLP file, see configuration of weasis-pacs-connector

That's all, now restart dcm4chee and launch Weasis from the dcm4chee-web3 portal.

For dcm4chee-web (old web interface - before 2.17.1)

  • Place these three files into the deploy folder (server/default/deploy/) of dcm4chee.
  • Modify the permission in /dcm4jboss-web/src/etc/conf/dcm4chee-web/folder.permissions or in server/default/conf/dcm4chee-web if dcm4chee is already installed

    folder.*=edit,move,delete,view,*export,edit.newStudyUID,mergepat,study_permission,study_permission.free_role_action,query_has_issuer folder.*export=export_tf,export_xds



That's all, now restart dcm4chee and launch Weasis from the web portal.

Write weasis-portable to DICOM CDs with dcm4chee-cdw

  • Install dcm4chee-cdw (see doc/INSTALL.txt in the archive)
  • Extract into the ../dcm4chee/server/default/data/mergedir directory
  • Go to the dcm4che jmx console (dcm4chee.cdw):
    •  Select the MediaCreationMgtSCP item and set to true the value of DefaultIncludeDisplayApplication
    •  Select the MakeIsoImage item and set to 4 the value of isoLevel
  • Click on the Apply Changes button

    Embedding a Java Runtime for Windows

    The executable (weasis-win32.exe) allows to embed a JRE in the directory "jre/windows" (weasis-portable/jre/windows/bin/java.exe). The embedded Java Runtime is used only when no runtime is available on the system. When Java is run from CD, it could be a little slow.

    i'm new in this solution, recently i installed the dcm4chee solution on a Windows Server 2003, using jboss ass a webserver, and it's works.

    now,i am trying  to incorporate this weasis solution, and i copied the two war files and reload the jboss wserver, but i don´t know how to modify the permissions. without the modification of the permissions all works fine, but the weasis icon doesn't appear.

    please help with that; and sorry about my english

      the problem was solve. the permission's folder was change in C:\apps\dcm4chee-2.16.2-mysql\server\default\conf\dcm4chee-web, folder.permissions file

      and this version of weasis only works with java 6-24, with 6-25 doesn't.
