ModeShape 3

Using Repositories with WebDAV in EAP

The ModeShape kit for EAP includes a WebDAV interface that clients can use to access, create, update, and delete update nt:file and nt:folder nodes in the repositories, treating these nodes as if they were simply files and folders on a network file system. Many applications and operating systems are WebDAV clients and can be used with ModeShape. For example, you can mount a repository (or parts of it) as a network drive on most operating systems, and then upload or download files and folders using standard OS operations and graphical tools. All ModeShape repositories can be accessed, and authentication is done using the ModeShape 'connect' role (although this can be customized).

The WebDAV service is packaged as a WAR file and is automatically deployed when the ModeShape kit is installed. Simply undeploy it if it is not needed.

The rest of this page describes connecting to the WebDAV service and advanced configuration.

Connecting to the repository with WebDAV

The WebDAV service is available on your EAP instance at the URL:

http://localhost:8080/modeshape-webdav/repositoryName/workspaceName/pathInWorkspace

where

  • repositoryName is the (required) name of the repository you want to connect to

  • workspaceName is the (required) name of the workspace to be accessed

  • pathInWorkspace is the JCR path to the top-level nt:folder (or nt:file) node to be accessed

For example, the following images shows how to use the Finder on OS X to connect to the "default" workspace in the "artifacts" sample repository included by default in the ModeShape installation.

Connecting to a repository over WebDAV

Once connected, your operating system or WebDAV client can simply access the content of the repository as if it were just a regular file system.

Configuring the ModeShape WebDAV Server

The ModeShape WebDAV server is deployed as a WAR and configured mostly through its web configuration files located within the deployment (at standalone/deployments/modeshape-webdav.war).

The WEB-INF/web.xml defines several parameters:

Parameter Name

Description

Value

org.modeshape.web.jcr.REPOSITORY_PROVIDER

The fully-qualified name of the class that implements the org.modeshape.web.jcr.spi.RepositoryProvider interface. Unless you are using the ModeShape WebDAV server to connect to a different JCR implementation, this should never change.

org.modeshape.web.jcr.spi.FactoryRepositoryProvider

org.modeshape.jcr.URL

This parameter, specific to the FactoryRepositoryProvider implementation, specifies the JNDI URL of the ModeShape Repositories implementation.

jndi:jcr

org.modeshape.web.jcr.webdav.CONTENT_MAPPER_CLASS_NAME

The fully-qualified name of the class that implements the org.modeshape.web.jcr.webdav.ContentMapper interface, which is responsible for mapping content nodes to WebDAV responses. The DefaultContentMapper implementation maps nodes with type nt:folder and nt:file to WebDAV folders and files, respectively (see other parameters). You can provide your own implementation to map WebDAV content to other node content or structures.

org.modeshape.web.jcr.webdav.DefaultContentMapper

org.modeshape.web.jcr.webdav.NEW_FOLDER_PRIMARY_TYPE_NAME

Each folder created through the WebDAV servlet will be created as a node with this primary node type.

nt:folder

org.modeshape.web.jcr.webdav.NEW_RESOURCE_PRIMARY_TYPE_NAME

Each resource (e.g., file) created through the WebDAV servlet will be created as a node with this primary node type.

nt:file

org.modeshape.web.jcr.webdav.NEW_CONTENT_PRIMARY_TYPE_NAME

Content created through the WebDAV servlet will be created as a node with the primary node type

nt:resource

org.modeshape.web.jcr.webdav.RESOURCE_PRIMARY_TYPE_NAMES

Nodes with any of the primary node types in this comma-delimited list will be exposed to WebDAV clients as file nodes.

nt:file

org.modeshape.web.jcr.webdav.CONTENT_PRIMARY_TYPE_NAMES

Nodes with any of the primary node types in this comma-delimited list will be exposed to WebDAV clients as content nodes (that is, nodes that have the content of the files).

nt:resource, mode:resource

There are also sections dictate how authentication is to be performed:

<!-- 
 The ModeShape WebDAV implementation leverages the HTTP credentials to for authentication 
 and authorization within the JCR repository.  Unless the repository provides for anonymous 
 access, it makes no sense to try to log into the JCR repository without credentials, so 
 this constraint helps lock down the repository.
 
 This should generally not be modified. 
-->
<security-constraint>
  <display-name>ModeShape WebDAV</display-name>
  <web-resource-collection>
    <web-resource-name>WebDAV</web-resource-name>
    <url-pattern>/*</url-pattern>
  </web-resource-collection>
  <auth-constraint>
    <!--  
      A user must be assigned this role to connect to any JCR repository, in addition to 
      needing the READONLY or READWRITE roles to actually read or modify the data.
    -->
    <role-name>connect</role-name>
  </auth-constraint>
</security-constraint>

<!--  
  Any auth-method will work for ModeShape.  BASIC is used this example for simplicity.
-->
<login-config>
  <auth-method>BASIC</auth-method>
</login-config>

<!-- 
  This must match the role-name in the auth-constraint above. 
-->
<security-role>
  <role-name>connect</role-name>
</security-role>
