OVERVIEW
The FileCatalyst Server supports writing to external file systems. Our
application can read and write directly to these cloud-based storage
vendors by adding them to the User account on the FileCatalyst Server.
The following is a list of storage vendors we currently support:
* Amazon S3
* Azure Blob
* OpenStack Swift
* Google Cloud Storage
* Backblaze B2
* Wasabi
* Dropbox (Labs)
We recognize that there are many vendors who support specific feature
sets, however, we wou...
Overview
For the last decade, we have embedded an SFTP module inside our
FileCatalst Server which was sourced using the Apache MINA libraries.
Security has been a foremost concern for our clients and in our last
few releases, we have tried to harden our security, for example making
all our software TLSv1.2 complaint out of the box. This is possible
since we can control the source code.
SFTP is highly secure and requires consistent updates to maintain
the security level. The update schedule fo...
OVERVIEW
For FileCatalyst Workflow and Webmail (discontinued), we have been
producing a Windows-based installer that contained an embedded Tomcat.
In the last five years, we have seen many vulnerabilities with Tomcat
which have been exposed such as POODLE, Logjam and other
man-in-the-middle attack variants. In some cases, Tomcat has been very
responsive to patching CATALINA and in other instances, there has been
the need to engineer a solution.
For the Windows platform, we currently have two ...
OVERVIEW
The FileCatalyst Server traditionally offered an installer on Windows,
Linux and macOS. Alongside these packages, we built tools to
administer these Servers which are called the Server Remote Admins.
With the recent changes announced by Apple about their
processors and the input we have received from our customers a
decision was made to move away from supporting the FileCatalyst Server
on macOS. There has been a significant decline in the number of
downloads for this installer in the ...
OVERVIEW
Internet Explorer has been the stock web browser that has been
packaged in every Windows OS. As of November 30, 2020, Microsoft plans
to end extended support for this browser. Following in the same
footsteps we will also be terminating support for Internet Explorer
browsers at this time as well.

Behaviour:
Trying to open the FileCatalyst Central Administration page results in
Central encountering a 500 error in the web browser. This occurs after
installation of Java Version 8 Update 91 or higher on Linux or Windows
Environments. MAC OSX users are unaffected by this update of Java 8.

OVERVIEW
There are two transfer features in the FileCatalyst HotFolder which
have shown some issues when used simultaneously. The Progressive
feature allows the HotFolder to transfer the file as it grows. The
Incremental feature will limit file transfers to files that are new
or have been modified. The Delta of a file is defined as portions of
the original file that have been modified or changed. Depending on the
Incremental setting selected, either the whole file or File Deltas
will be sent t...
OVERVIEW
When hosting the FileCatalyst Server on Amazon Web Services (AWS) -
EC2 instances, S3 buckets can be added to the FileCatalyst Server as
an external storage device. Amazon provides libraries that we have
used to integrate this storage device into the Server where we can
read and write to this endpoint.
In FileCatalyst Server v3.6 beta 27, when the Security Group on the
EC2 instance is set to allow all IPs the transfer experiences some
packet loss and when our congestion control algor...
OVERVIEW
Google has made changes in the default settings of Chrome version 42,
released April 14th, 2015, that block Java applets from running in
that browser.
This is part of Google’s announced strategy
(http://blog.chromium.org/2014/11/the-final-countdown-for-npapi.html
[http://blog.chromium.org/2014/11/the-final-countdown-for-npapi.html])
of eliminating all NPAPI (or NP-API) applet support by September 2015.
For FileCatalyst users, this means that right now you are going to be

OVERVIEW
FileCatalyst Workflow v4.9.9 introduced a new feature called Strict
Security. This feature requires the use of the Administration account
on the FileCatalyst Server to create and authenticate Virtual Users on
the FileCatalyst Server. On Workflow deployments which have a large
volume of activity the Server Remote Admin connections can multiply
and remain open for long periods of time. These open connections hang
and do not close properly. If you use Strict Security as part of your
deploy...
OVERVIEW
When you use Java 7 to run the FileCatalyst HotFolder, it can not
delete a task from the HotFolder Web Admin UI. This issue was observed
when using the FileCatalyst HotFolder Web Admin through FileCatalyst
Central or connecting directly to the FileCatalyst HotFolder
deployment.
This issue is only present in Java 7 RE and Java 7 DK.
Environment
Oracle Java 7
FileCatalyst HotFolder v3.7.1 and newer.
Resolution
The best solution would be to upgrade the Java deployment on the

Overview
Currently, there is a known issue with transferring files that contain
some Asian characters in the file name when using the OpenStack EFS
driver on the FileCatalyst Server.
This is currently impacting our 3.7.1 build 7 and newer releases. This
issue is client independent as the Server contains the driver in
question.
We are actively working to resolve this and will update this
notification when we have news.
Environment
FileCatalyst Server v3.7.1 and newer.

In Tomcat 9, the core engine starts up faster than previous Tomcat
versions and the web front end is active. This means that the HTTP
Connector is open and listening to requests from your web browser.
Our application which is a container in the application is still
starting and as a result, the end user is presented with a HTTP 500
error.

OVERVIEW
A recent update to the Firefox framework introduced behaviour where
the sessionStorage information no longer persists across new tabs
created by our web applications. For example, new tabs are created
with the activity views and Server log pages. Because of the new lack
of persistence, our web applications experience issues when attempting
to authenticate WebSocket connections with the underlying WebServers.
These issues cause the customer's pages to properly load, which then
leads to ...

In October of 2015, Mozilla had issued an advisory where Firefox
Development intends to remove support for most NPAPI plugins by the
end of 2016. (NPAPI Plugins in Firefox

With Oracle releasing Java 9, clients may encounter issues running
older versions FileCatalyst applications. This issue will only impact
clients using Windows and Linux Environments.
The resolution section will outline how to configure the various
FileCatalyst Direct Applications for use with Oracle Java 9.
The parameter that needs to be added is located in the Java Additional
Properties section in the FileCatalyst configuration file.

OVERVIEW
The TransferAgent Client contains an SSL Certificate to secure the
domain localhost.filecatalyst.net. This domain is used to access the
configuration pages and the Express application that is hosted inside
the TransferAgent client.
Older builds of TransferAgent (older than v3.7.1) that have not been
upgraded at customer's site will start having a warning dialog when
they try to browse to the TransferAgent. The warning looks something
like this:
