Configuration
Application Properties
jmix.webdav.applications
Maps document formats to external applications that should open these documents. For each application you can configure a set of file extensions in the "extensions"
property.
For example, the following mapping makes the system to open PPT and PPTX files with Microsoft PowerPoint:
"ms-powerpoint":{\
"name":"Microsoft PowerPoint",\
"protocols":{"writable":"ms-powerpoint:ofe%7Cu%7C","read_only":"ms-powerpoint:ofv%7Cu%7C"},\
"extensions":["ppt","pptx"]\
}
Default value:
{"ms-word":{"name":"Microsoft Word","protocols":{"writable":"ms-word:ofe%7Cu%7C",\
"read_only":"ms-word:ofv%7Cu%7C"},"extensions":["docx","doc","rtf"]},\
"ms-excel":{"name":"Microsoft Excel","protocols":{"writable":"ms-excel:ofe%7Cu%7C",\
"read_only":"ms-excel:ofv%7Cu%7C"},"extensions":["xls","xlsx"]},\
"ms-powerpoint":{"name":"Microsoft PowerPoint",\
"protocols":{"writable":"ms-powerpoint:ofe%7Cu%7C","read_only":"ms-powerpoint:ofv%7Cu%7C"},\
"extensions":["ppt","pptx"]}}
Example value for LibreOffice:
jmix.webdav.applications = {"vnd.libreoffice.command":\
{"name":"LibreOffice","protocols":\
{"writable":"vnd.libreoffice.command:ofe|u|",\
"read_only":"vnd.libreoffice.command:ofv|u|"},\
"extensions":["odt", "ods", "odp", "doc", "docx", "xls", "xlsx", "ppt", "pptx"]}}
jmix.webdav.authentication-method
Defines the authentication type.
Default value: basic
.
Although it is not recommended, you can set digest
in this property and avoid setting up HTTPS on the server. In this case, do not forget to change the jmix.webdav.url-prefix property for generating links with correct server protocol and port. Also note that all users must have hashed passwords stored separately in the database. The add-on updates these passwords when you change the password for a user, so you have to do it for each user after setting up the digest authentication.
jmix.webdav.auto-generate-unique-resource-uri
If this property is set to false
and a newly uploaded document has the URI already assigned to another document, the unique constraint violation occurs.
If this property is set to true
and the URI is already assigned to some document, then the new path will be automatically generated with the {id}.extension
format.
Default value: true
.
jmix.webdav.document-versions-cleaning-cron
This property allows you to change the schedule of WebdavDocumentVersionsCleaningJob as cron expression if necessary.
The default value is 0 0 0 1 * ? *
(once a month).
jmix.webdav.expired-lock-cleaning-cron
This property allows you to change the schedule of ExpiredLockCleaningJob as cron expression if necessary.
The default value is 0 0 0/2 ? * *
(every two hours).
jmix.webdav.file-storage
Defines a file storage used for storing WebDAV files.
By default, a file storage returned by FileStorageLocator.getDefault()
is used.
jmix.webdav.lock-timeout
Defines the default interval in milliseconds for a document locking.
Default value: 600000
.
jmix.webdav.use-default-document-versions-cleaner-quartz-configuration
This property allows you to disable the default configuration that creates and schedules the WebdavDocumentVersionsCleaningJob job.
Default value: true
.
jmix.webdav.use-default-expired-lock-cleaner-quartz-configuration
This property allows you to disable the default configuration that creates and schedules the ExpiredLockCleaningJob job.
Default value: true
.
Configuring HTTPS
HTTPS on the server is required to authenticate desktop applications. Below are simple instructions for setting up HTTPS in your development environment.
The use of a self-signed certificate is appropriate only for testing. Always use SSL certificates issued by a trusted authority for running production applications. |
Creating a Keystore File
-
Generate a keystore using the keytool utility provided by JDK:
keytool -genkey -keyalg RSA -alias localhost -keystore localhost.jks -validity 365 -keysize 2048
You will be asked for the keystore password and then for some names. Remember the password and the names.
-
Export certificate from the keystore:
keytool -export -keystore localhost.jks -storepass <password> -alias localhost -file localhost.cer
Use the password entered on the first step instead of
<password>
. -
Register the certificate as trusted in your operating system.
-
On macOS:
-
Double-click on
localhost.cer
file in Finder. The Keychain Access application will open. -
Find your certificate under the name entered on the first step as "your first and last name" on the Certficates tab.
-
Double-click the certificate and select Trust → When using this certificate: Always Trust.
-
-
Configuring Server
This section explains how to use the certificate generated in the previous section in your application when it runs from the IDE or as an executable JAR.
-
Create
src/main/resources/<base-package>/keystore
directory and copylocalhost.jks
into it. -
Set the following properties in the
application.properties
file replacing<base-package>
and<password>
with actual values:# Enables HTTPS server.ssl.enabled=true # The format used for the keystore server.ssl.key-store-type = JKS # The path to the keystore containing the certificate server.ssl.key-store = classpath:<base-package>/keystore/localhost.jks # The password used to generate the keystore server.ssl.key-store-password = <password> # The alias mapped to the certificate server.ssl.key-alias = localhost # Changes the server's port server.port = 8443
Maintenance Tasks
To use Quartz Job Scheduler for periodic invocation of maintenance tasks, include Quartz in your project as described in the Quartz Job Scheduler Setup section.
ExpiredLockCleaningJob
Removes expired lock objects. This job runs every two hours by default.
To change the job schedule, use the jmix.webdav.expired-lock-cleaning-cron property.
WebdavDocumentVersionsCleaningJob
Removes WebdavDocumentVersion
instances, which do not have links to documents. This job runs once in a month by default.
To change the job schedule, use the jmix.webdav.document-versions-cleaning-cron property.
