Listing User Sandboxes

On clicking on the web project, the sandbox view appears displaying the Staging and User Sandboxes Each User Sandbox contains the existing web project content

The sandbox labeled My Sandbox belongs to the currently logged in user (in this

case, the administrator) As the administrator, you have access to the sandboxes of all users associated with the web project

By default, only the Staging Sandbox and the User Sandbox display; however, you

can select the Show All Sandboxes option in this view to display all the sandboxes

available to you, as shown in the following screenshot:

[ 94 ]

Refresh your browser page to view all the User Sandboxes if the browser is not refreshed automatically

You cannot add the content directly to the Staging Sandbox Here is the process you need to follow in order to create the content

1 Create content in your User Sandbox either by uploading the files or using bulk import feature

2 Preview the content to ensure the accuracy

3 Optionally verify the broken links using the links checker

4 Submit the approved content to the Staging Sandbox

5 Deploy the content from Staging Sandbox to external servers using the filesystem deployer

Add content to the web project

There are multiple methods of adding and creating content for a web project In addition to creating web content within a project, you can also upload individual files from your computer or perform a bulk import of a ZIP file with web project contents as shown in the following screenshot:

When you install WCM, you will also get sample files to create web projects Refer to the file alfresco-sample-website.war, which is provided as a default example in the Alfresco bundle, from c:\alfresco\extras\wcm

Trang 4

[ 95 ]

To bulk import content of this file, select Bulk Import in the Create menu Use the

Browse button to locate and upload the alfresco-sample-website.war file Once

uploaded, click on OK to begin the import.

The war file, which you imported into the current directory (the ROOT webapp), appears in expanded form in your User Sandbox

If you don't have the sample war file, then add few sample files to your User

Sandbox from your local computer using the Add Content option In the Alfresco

WCM, a lock is automatically placed on content items created, imported, modified,

or deleted, in order to prevent editing clashes In our sandbox, notice that all of the items (not folders) currently display a padlock icon with a key ( ) This indicates that you own the lock and can perform actions on the content A lock owned by another user appears as a plain padlock ( ) You can position the mouse cursor over the icon to display a tooltip indicating the lock owner

Click on Preview Website in the sandbox header to see the website in its current state.

The preview window displays how the website or web application will look with the

submitted User Sandbox content Click on About us and then on News to display the empty Alfresco Press Releases page You will come back to this again later once

you have added some content

Close the preview and return to User Sandbox Click on Project Name in the

breadcrumb path to return to the sandbox view

Submit content to the Staging Sandbox

At this point, the web project is populated with content items, some imported

and some created, some submitted and some not You must now deal with the submission of the remaining items to staging

Trang 5

[ 96 ]

In the User Sandbox, expand the Modified Items list to display the imported content.

Click on Submit All and, on the Submit Items page, provide the information that

will display as the name and description of the corresponding snapshot in staging:

Label: Initial Import

Description: Sample Website

Trang 6

[ 97 ]

Click on OK The submission takes place in the background and each content item remains in the Modified Items list until its submission is complete.

Refresh the page as necessary until the Modified Items list is empty In the Staging Sandbox, expand the Recent Snapshots list to view the snapshot you have created as

shown in the following screenshot:

Filesystem projection

The AVM repository and its virtual stores are made available by projection

through CIFS

To mount the CIFS directory in Windows Server/XP, follow these steps:

1 Open up Windows Explorer

2 Under the Tools menu, Select Map Network Drive….

3 Select an available drive letter Example: Z:.

Trang 7

[ 98 ]

4 For Folder enter the CIFS server name Example:

\\<your_server_name>A\AVM

Windows will open the mapped drive and you should see something similar to the following that includes the current web projects:

AVM CIFS projection provides:

• Access to all available sandboxes (Read/Write)

• Access to all available layers (Preview)

• Access to all snapshots in read-only mode under top-level Versions Directory

• Access to all file metadata under top-level METADATA directory

• Mounting of AVM virtual store "docroots" to test servers

Bulk loading of content XML files and previously rendered files (HTML, XML, and RSS feeds) will not recreate mapping between source file -> rendering template -> output file This is also the case for bulk uploads into a web project

There is a Web Projects tool on the Alfresco Forge, but it is for Version 2.2 These tools provided import and export features, and re-association of renditions with content and templates, among others

Virtualization server

A Virtualization server is a customized version of Tomcat that treats each User Sandbox, Staging Sandbox, and workflow instance as a separate Tomcat web

application It understands an "overloaded" hostname format that allows it to map requests to specific sandboxes These "overloaded" hostnames use wildcard DNS entries to map all request to the same Alfresco Virtualization server

Configuring the virtual server for preview

The configuration files for the virtual server can be found in the <alfresco home>/ virtual-tomcat/conf directory To enable previews on a development machine, you need to modify the alfrescovirtserver.properties file to utilize the Alfresco wildcard DNS service The alfresco.virtserv.domain value needs to be updated

to replace 127-0-0-1 with the IP of the Alfresco local machine, substituting all "." with dashes:

# Alfresco's free/public wildcard domain service ("EchoDNS")

# returns resource records with a TTL of 1 day Therefore,

# the run-time overhead is quite minimal Once the machine

# has done a name lookup, it will cache the result for the

# next 24 hours (or until you reboot).

#

alfresco.virtserver.domain=127-0-0-1.ip.alfrescodemo.net

If the IP of the Alfresco machine is 192.168.1.25, update alfresco.virtserver domain to alfresco.virtserver.domain=192-168-1-25.ip.alfrescodemo.net Alfresco Virtual Server needs to be restarted at this point

Virtualization URL format

The general format for Alfresco virtual hyperlink is:

http://virtual-hostname.www sandbox.virtualization-domain:port/ request-path

Trang 9

[ 100 ]

where the virtual-hostname is defined as the DNS name when creating a web project, and the virtualization-domain is the wildcarded domain name entry that maps to the Alfresco Virtualization Server The default port for a virtualization server is 8180 Given that a web project was created with "test" as the DNS name, (*.virtualserver.unico.com is a DNS entry for Virtualization Server) and is installed on the default port, the following are true:

• http://unicom.www sandbox.virtualserver.unico.com:8180/ is the preview of the Unicom web project for the Staging Sandbox

• http://admin.unicom.www sandbox.virtualserver.unico.com:8180/

is the preview of the root of the Unicom web project for the admin user's sandbox

• http://jsmith.unicom.www sandbox.virtualserver.unico.com:8180/ index.html is the preview of the file /index.html of the web project in the jsmith user's sandbox There are variations of this for previewing new content before the initial persistence and previews for items within

a workflow

Virtualization server access to the User

Sandbox

The AVM repository and its virtual stores are mapped into the virtual Tomcat working directory:

$VIRTUAL_TOMCAT_HOME/work/Catalina/avm.alfresco.localhost/

This working directory will contain directories like the following, which are similar

to the naming CIFS convention for virtual stores:

TABLE[

$-1$mysite admin preview$ROOT/ $-1$silly admin preview$ROOT/

$-1$mysite admin$ROOT/ $-1$silly admin$ROOT/

$-1$mysite alice preview$ROOT/ $-1$silly alice preview$ROOT/

$-1$mysite alice$ROOT/ $-1$silly alice$ROOT/

$-1$mysite bob preview$ROOT/ $-1$silly preview$ROOT/

$-1$mysite bob$ROOT/ $-1$silly-$ROOT/

$-1$mysite preview$ROOT/ host-manager/

$-1$mysite$ROOT/ manager/

$42$mysite$ROOT/]

Virtual server configuration

Configure the virtual server to allow the previewing of content and review some

of the content in the CIGNEX web project in the user's sandbox Once you are

satisfied that the preview is working, submit the whole project to staging After the submission is complete, preview the website in the Staging Sandbox

1 Determine the current IP of the Alfresco machine using one of the following:

° Windows—open CMD prompt and run the ipconfig command

° Unix(s)—open terminal and run ipconfig -a

2 Open the virtserver.properties file found in the <alfresco home>/ virtual-tomcat/conf directory

c:\Alfresco\virtual-tomcat\conf\virtserver.properties

3 Modify the following line to use the IP found in step one, replacing

all "." with "-" :

For IP of 192.168.1.100 the line would be:

4 Save and exit the file

5 Start or restart the Virtual Server

6 Test previewing the file in the user's sandbox

Click on Submit All to send all files to the staging environment Test preview in the

Staging Sandbox Previewing in the User and Staging Sandboxes should work

Dynamic websites using WCM

A web project it not limited to just static files Web projects can include server-side scripting files including JSP, PHP, CF, or Python files In the end, these files would

be published to the appropriate application server or web server enabled to evaluate these files Specifically for Java, Alfresco supports the evaluation of JSPs and exploded WARs within a web project with support for preview of JSPs by the Virtual Server You could upload archived WARs, have Alfresco deploy them to a web application server for unpacking, and so on For Tomcat, it could place them in the

webapps directory
