JBoss6 serve external file static content docBase vhost

Par PlaceOweb le vendredi, novembre 11 2011, 18:32 - JAVA - Lien permanent

There are no more "virtual directories" in JBoss 6. Apparently this went out with JBoss 5. The only availables options or solutions I've found are :

  • Way 1 : using 2 war, one for your project, one other to publish static files (under another
  • Way 2 : symlink (to a simple file system or on a war folder with inside a blank /WEB-INF)

Using ExternalDirectories doesn't work with JBoss 6

<Host name="localhost" ...>
        <!-- ADD static images DIRECTORY -->
        <Context path="/images" 
                docBase="/home/myuser/images"
                reloadable="true">
        </Context>
        <!-- The rest of your Host entity -->
</Host>

This Context deployement result :

ERROR [AbstractKernelController] Error installing to Start: name=WebServer state=Create: org.jboss.xb.binding.JBossXBException: Failed to parse source: xml_stream@163,112

DEPLOYMENTS IN ERROR:
 Deployment "WebServer" is in error due to the following reason(s): **ERROR**, org.jboss.xb.binding.JBossXBRuntimeException: DefaultContext not found as a child of Host in unordered_sequence: Listener* Valve* Alias* Realm? attributes?
 Deployment "jboss.web:service=WebServer" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.web:service=WebServer' **

Solution : Way 1

Under you war (unzipped when deployed), in file "myProject\WebContent\WEB-INF\jboss-web.xml"

<?xml version="1.0" encoding="UTF-8"?>
<!-- http://www.jboss.org/schema/jbossweb/jboss-web_6_0.xsd -->
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-web_6_0.xsd"
           version="6.0">
 
           <context-root>/files</context-root>
           <virtual-host>publicweb1</virtual-host>
 
</jboss-web>

With your backoffice, write in this unzipped deployed war, to serve static files.

Solution : Way 2

Adding allowLinking="true" in Jboss context (C:\jboss-6.1.0.Final\server\default\deploy\jbossweb.sar\context.xml)

<Context cookies="true" crossContext="true" allowLinking="true">
...

or only in your project (DeployedProject\WebContent\WEB-INF\context.xml)

<Context allowLinking="false">
 
</Context>

All others context (with or not vhost) inherit the attribute allowLinking="true" and the symbolic link is working inside my DeployedProject.war/mySymLink




Adding the system symbolic link : DeployedProject.war/mySymLink linked to /tmp



DeployedProject.war# ln -s /tmp mySymLink




Now, you can access to http://localhost:8080/DeployedProject/mySymLink/myPicture.jpg and myPicture.jpg is stored in /tmp/myPicture.jpg






Enjoy, and if you can solve this problem without symlink...




An alternative way to returning files outside war, seem to be using a servlet, for get and return external file system... not try, but exemples in followings links.





External Static Directories Ressources







    

  • jbossweb
    • 

  • The Resources Component The Resources element represents the web application static resources, from which classes will be loaded, HTML, JSP and the other static files will be served. Note: Running a webapp with non-filesystem based Resources implementations is only possible when the webapp does not rely on direct filesystem access to its own resources, and uses the methods in the ServletContext interface to access them.
    • 

  • The Context Container The Context element represents a web application, which is run within a particular virtual host.

      

    • docBase : The Document Base (also known as the Context Root) directory for this web application, or the pathname to the web application archive file (if this web application is being executed directly from the WAR file). You may specify an absolute pathname for this directory or WAR file, or a pathname that is relative to the appBase directory of the owning Host.
      • 

    • path : The context path of this web application, which is matched against the beginning of each request URI to select the appropriate web application for processing. All of the context paths within a particular Host must be unique. If you specify a context path of an empty string (""), you are defining the default web application for this Host, which will process all requests not assigned to other Contexts. The value of this field must not be set except when statically defining a Context in server.xml, as it will be inferred from the filenames used for either the .xml context file or the docBase.

      • Serving Static Content: JBoss provides a default application that serves content for the root application context. This default context is the ROOT.war application in the jbossweb-tomcat50.sar directory. You can serve static files not associated with any other application by adding that content to the ROOT.war directory. For example, if you want to have a shared image directory you could create an image subdirectory inside of ROOT.war and place the images there. You could then access an image named myimage.jpg at http://localhost:8080/images/myimage.jpg.
