Accessing static files through Apache HTTP Server in Linux

Accessing static files through Apache HTTP Server in Linux

This post will explain accessing static files through Apache HTTP Server in Linux

Create  a folder in server to store the static files  e.g. /app/apache/static/

Copy all the static files to /app/apache/static/ folder

Add the below contents to httpd.conf file

##Grant the access to unix user that will access the static folder
<IfModule unixd_module>
      User apacheuser
      Group apacheuser

DirectoryIndex index.htm index.html

ErrorDocument 400 /error.html
ErrorDocument 401 /error.html
ErrorDocument 403 /error.html
ErrorDocument 404 /error.html
ErrorDocument 405 /error.html
ErrorDocument 408 /error.html
ErrorDocument 414 /error.html
ErrorDocument 500 /error.html
ErrorDocument 502 /error.html
ErrorDocument 504 /error.html

<VirtualHost *:80>
  DocumentRoot /app/apache/static/

 Alias /files  "/app/apache/static"

<Directory /app/apache/static>
    Order deny,allow
    Allow from all
    SetHandler default-handler

Now we can access the static file with the following url -<<file name>>

The Apache server referred here is 2.2.15

403 Forbidden/403 XSRF Protection Failure error while invoking Eloqua Send mail API

403 Forbidden/403 XSRF Protection Failure error while invoking Eloqua Send mail API

We will be receiving 403 Forbidden/ 403 XSRF Protection Failure error while invoking the Eloqua Send mail API - /api/rest/1.0/assets/email/deployment

Verify whether the user has the role "Engage Users", if not add the "Engage Users" security group to the user and Save the changes.

If the Engage Users role is already added then clear the browser cookies and try again.

Checkout: Unable to mount filesystem - Adobe Experience Manager(AEM)

Sometimes you may receive the following exception while exporting the  repository content to eclipse through vault.

Jcr File Vault [version 2.4.34] Copyright 2011 by Adobe Systems Incorporated
[ERROR] checkout: Unable to mount filesystem
caused by: javax.jcr.RepositoryException: URL scheme http not supported. only

For me the issue got fixed after clearing the temp folder contents.

How to configure Hybris Server to use Oracle Data Base

How to configure Hybris Server to use Oracle Data Base

The following steps can be followed to configure the Hybris server to use Oracle database.

Configure database user:

Login to Oracle database and create the required user and provide the grants.
create user <username> identified by <password> default tablespace <table space name> temporary tablespace <table space name>;
grant connect, resource to <username>;

Configure Hybris server

Copy the oracle driver (e.g. ojdbc6.jar) to /hybris/bin/platform/lib/dbdriver

Go to /hybris/config and edit by adding the following:
db.url=jdbc:oracle:thin:Username/password//servername:port-id/database name

Verify the configuration details and initialize

Access the Hybris server URL and check the following details:
                   a) Database Name displayed
                   b) User name Displayed
                   c) Database Driver Displayed.
                   d) Check for the default objects (e.g. product, cart etc) already selected.

Click on initialize button on the top of the page. It will take some time and initialize all the tables, table spaces and schemas required.

After successful completion of initialization the server gets automatically restarted, or else it will display errors which need to be rectified.
