Preferences
The WEB distribution (weasis.war) allows delivering preferences from the server-side to the client-side. Some preferences on the server-side are used by Weasis only during the first launch because they can be changed later in the Weasis user interface. The other preferences at the server-side are used by Weasis at every launch.
Local preferences can be changed by:
- The Weasis user interface: File > Preferences
- The weasis protocol with the command weasis:config and the pro parameter
Preferences on the server-side can be changed by:
- Replacing ext-config.properties which extends and overrides config.properties, see the tip below.
- Using query parameters in weasis-pacs-connector
- The weasis protocol with the command weasis:config and the pro parameter
Tip
How to modify ext-config.properties:
- Unzip weasis.war, modify the file and zip it again.
- It is also possible to change the default location of ext-config.properties with the Java property “felix.extended.config.properties” with the parameter
cdb-extof the weasis service . The ext-config.properties file can also be placed in a plugin package, see How to build and install a plug-in .
Priority order for loading a property
Here is the priority order to set a property:
- Java System property providing from parameters of weasis:config or the launching URI )
- Property defined in weasis/conf/ext-config.properties or in weasis/conf/config.properties
- The default value of the property (see table below)
Example to change language property (It will work only during the first launch of Weasis on a user session, otherwise delete ${user.home}/.weasis/preferences/).
- If you are using weasis-pacs-connector, add the property
locale.lang.code:http://localhost:8080/weasis-pacs-connector/weasis?patientID=9702672&pro="locale.lang.code%20fr_CH" - Add the property in weasis/conf/ext-config.properties:
locale.lang.code=fr_CH - The default value is “en_US”

Examples of properties in ext-config.properties
Changing the default theme of the user interface
# Define the theme for the first launch according to the platform (macosx, linux, windows)
weasis.theme=org.weasis.launcher.FlatWeasisTheme
weasis.theme.macosx=com.formdev.flatlaf.FlatIntelliJLaf
weasis.theme.linux=com.formdev.flatlaf.FlatDarculaLafCustomize resources
The default resources are located:
- For the web distribution in “resources.zip” at the root of weasis.war (see above how to set a new URL for resources)
- For the installed distribution in installedPath/app/resources
How to add DICOM nodes or DICOM printers at the server-side
- From the graphical user interface, configure the DICOM printers (File > Print > DICOM Print) or DICOM nodes (File > Preferences > Dicom node list)
- Go to the folder ${user.home}/.weasis/data/weasis-dicom-explorer
- Copy the desired configuration files: dicomNodes.xml, dicomPrinterNodes.xml, dicomWebNodes.xml and dicomCallingNodes.xml
- Paste at the root path of resources. For web distribution, unzip, place files and zip again.
- The new configurations should appear for all the users as non-editable configurations in Weasis.
