Virtuoso Sesame Provider displays the blank page when clcik on new repo - sesame

I have configured my sesame according to this tutorial (http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository) to add virtuoso extension into it . When i click on new repository, it display blank page. Can anyone tell me where i did mistake.
I just performed the following steps.
Setup Sesame HTTP Repository
This section details the steps required for configuring and testing a Virtuoso HTTP Sesame Repository.
Install Apache Tomcat web server
From the Sesame 2.3.1 or higher "lib" directory copy the "openrdf-sesame.war" and "openrdf-worbbench.war" files to the tomcat "webapps" directory where they will automatically be deployed creating two new sub directories "openrdf-sesame" and "openrdf-workbench".
Place the Virtuoso Sesame Provider "virt_sesame2.jar" and JDBC Driver "virtjdbc3.jar" into the Tomcat ~/webapps/openrdf-sesame/WEB-INF/lib/ and ~/webapps/openrdf-workbench/WEB-INF/lib/ directories for use by the Sesame HTTP Repository for accessing the Virtuoso RDF repository.
Place the "create.xsl" and "create-virtuoso.xsl" files in the Tomcat ~/webapps/openrdf-workbench/transformations/ directory. Note "create.xsl" replaces the default provided with Sesame and contains the necessary entries required to reference the new "create-virtuoso.xsl" template file for Virtuoso repository configuration.
The Sesame HTTP Repository will now be accessible on the URLs
http://localhost:8080/openrdf-sesame
http://localhost:8080/openrdf-workbench
The Sesame OpenRDF Workbench is used for accessing the Sesame HTTP Repositories, loading "http://localhost:8080/openrdf-workbench" will enable the default "SYSTEM" repository to be accessed.

What kind of version Virtuoso Sesame provider did you use?
NOTE:
Virtuoso Sesame provider ver >= 2.7.3 required virtjdbc4.jar file(Virtuoso JDBC driver) instead of virtjdbc3.jar.

For a given path, even it finds the resource in Git, it still queries vault and report failure as the resources are not available at both sources. My requirement is to look for a resource and if its found, no need to query the other source. Please suggest if its possible. Thanks

Tomcat8 The origin server did not find a current representation for the target resource or is not willing to disclose that one exists

HTTP Status 404 – Not Found

It works !
If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!
This is the default Tomcat home page. It can be found on the local filesystem at: /var/lib/tomcat8/webapps/ROOT/index.html
Tomcat8 veterans might be pleased to learn that this system instance of Tomcat is installed with CATALINA_HOME in /usr/share/tomcat8 and CATALINA_BASE in /var/lib/tomcat8, following the rules from /usr/share/doc/tomcat8-common/RUNNING.txt.gz.
You might consider installing the following packages, if you haven't already done so:
tomcat8-docs: This package installs a web application that allows to browse the Tomcat 8 documentation locally. Once installed, you can access it by clicking here.
tomcat8-examples: This package installs a web application that allows to access the Tomcat 8 Servlet and JSP examples. Once installed, you can access it by clicking here.
tomcat8-admin: This package installs two web applications that can help managing this Tomcat instance. Once installed, you can access the manager webapp and the host-manager webapp.
NOTE: For security reasons, using the manager webapp is restricted to users with role "manager-gui". The host-manager webapp is restricted to users with role "admin-gui". Users are defined in /etc/tomcat8/tomcat-users.xml.
but i need apache tom server site

Accessing file system resources using the Apache Sling Resource API

I want to access the file System using the sling resource API . I can access the JCR nodes but not don't know how to access the file System resource . How the resourceResolver will resolve the resource objects for filesystem ?
To access filesystem resources a Sling Resources you need to install the org.apache.sling.fsresource bundle and create at least one OSGi configuration to activate it.
See the docs at
http://sling.apache.org/documentation/bundles/accessing-filesystem-resources-extensions-fsresource.html

Automatic JDBC Realm configuration

I want to know if it's possible to create JDBC Realm configuration in Glassfish 3.1 without admin console, like creation of a Data Source with the glassfish-resources.xml.
When developers download my GIT repository they don't like to configure Glassfish, it's configured in deployment time.
Best regards
Mounir
I'd create a shell script or batch file which runs the required asadmin commands.
Here you can find a complete example: Creating JDBC Objects Using asadmin
(Btw, DTD of GlassFish Resources Descriptor does not contain any realm-related tag (include create-auth-realm).)

Access older revision of SVN repo via HTTP / mod_svn

Using the mod_svn module for apache you can access the repository not onl via SVN client but also directly via HTTP using the same URL. You only get a plain directory listing showing the HEAD revision in such a case.
It is possible (may be via URL parameters) to access older revisions of the SVN repository if they has net been copied/tagged within the SVN?
I know that there are 3rd party software that allows to do so like ViewCV or WebSVN but I am interested in how far you get with only a plain SVN repository accessible via mod_svn and HTTP(S).
You can use the r querystring parameter to access older versions of files and directory listings with mod_dav_svn. For example:
http://host.example.com/repos/project/trunk/README.txt?r=1234
The SVN Book has more details on how this works.
