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.

 

Weasis in dcm4chee-arc-light
Weasis in dcm4chee-web3
dcm4chee-web


For dcm4chee-arc-light

  • Install dcm4chee, if not already done.

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

      • 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.

    • Select the “Deployments” tab
    • Add the .war files using the “Add” button (Choose Upload a new deployment or select Replace when the file already exists)


  • Configure weasis-pacs-connector (Required to change the default WADO configuration)
    The default configuration is stored in two files inside weasis-pacs-connector.war.
    To override the default configuration:

    • Go here.

      Requires weasis-pacs-connector 6.x and superior: Download the current weasis-connector-default.properties and rename it weasis-pacs-connector.properties, and download dicom-dcm4chee.properties (configuration of the dcm4chee archive)

      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 wildfly/standalone/configuration.
    • As the default configuration of dicom-dcm4chee.properties is defined for dcm4chee-web3, it is necessary to modify at least:   
      • The WADO url of arc-light: arc.wado.url=${server.base.url}/dcm4chee-arc/aets/DCM4CHEE/wado

      • To accept all the syntaxes (otherwise arc-light will uncompress all the images): wado.addparams=&transferSyntax=*

    • 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 weasis-pacs-connector.properties or dicom-dcm4chee.properties (Change pacs.host, pacs.port, and pacs.aet).
    • To add new properties or arguments in the JNLP file, see configuration of weasis-pacs-connector


  • To activate Weasis in dcm4chee-arc-light user interface (required 5.10.2 or superior), you need need to changes two attributes in the configuration

For dcm4chee-web3

  • Install dcm4chee, if not already done. For security see also how to limit the server access.
    • 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 dcm4chee.org 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

        weasis-pacs-connector configuration

        The new way of launching Java Westart file (jnlp) will require an absolute URL:

        • weasis:jnlp://YOUR-host:8080/weasis-pacs-connector/viewer
        • weasis:jnlps://YOUR-host:8443/weasis-pacs-connector/viewer (SSL connection)

        From dcm4chee 2.18.3, it possible to reuse the host name of dcm4chee:

        • weasis:jnlp://${server.host}:8080/weasis-pacs-connector/viewer
        • weasis:jnlps://${server.host}:8443/weasis-pacs-connector/viewer
    • 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 AETitle DCM4CHEE has been changed)
    The default configuration is stored in two files inside weasis-pacs-connector.war.
    To override the default configuration:

    • Go here.
      weasis-pacs-connector 4.x and 5.x: Download weasis-connector-default.properties and rename it weasis-pacs-connector.properties

      weasis-pacs-connector 6.x and superior: Download the current weasis-connector-default.properties and rename it weasis-pacs-connector.properties, and download dicom-dcm4chee.properties (configuration of the dcm4chee archive)

      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 weasis-pacs-connector.properties or dicom-dcm4chee.properties for weasis-pacs-connector 6.x. Change pacs.host, 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

    ...

    folder=WebUser(send,view);DatacareUser(edit,move,delete,export_xds,view);WebAdmin(*)

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 weasis-portable.zip 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 (viewer-win32.exe) allows to embed a JRE in the relative directory "jre/windows" (e.g. weasis-portable/jre/windows/bin/java.exe). To support 32 and 64-bit architecture, copy 32-bit Java Rutime from its installed directory.

    Note: 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.
