New Version for Conversion Released – DPF 3.0

by Dr. Uwe Wächter

In the last two years, there have been many new features and improvements of the different products and components of SEAL Systems. Since the end of May 2021, a new version for conversion has been released – DPF 3.0. This new version is available as a new release for our customers. This article describes the most important innovations and discontinuations.

New Features and Improvements

As of this release, the Digital Process Factory® (DPF) is also available on Linux: both Windows and Linux Server programs are 64-bit versions.

The command line DPF client uses the REST web service internally. This replaces the proprietary file transfer protocol FRANS. This makes the transfer more secure and requires fewer open ports. For a transition period, the old method will still be supported.

The new DPF SAP Retriever component is included in the scope of delivery for using the DPF in SAP conversion servers. This allows direct communication with the Conversion Control Center (CCC) from CIDEON. This means that projects without CAD conversions can also be implemented directly with the DPF without a detour via the CIDEON CEC (Conversion Engine Client).

SAP Viewserver

The SAP Viewserver has been completely revised: The script-based solution was replaced by the two flexible, extensible DPF processes, “DPF4VIEW.main” and “DPF4VIEW.list”. This simplifies customer-specific extensions— monitoring and operating use the proven tools known from other DPF solutions.

We know many requirements from previously implemented projects, such as stamps, signature pages, and PDF encryption, are included in the standard with the new version. In addition, the new processes are largely compatible with the change header scripts of the old solution so that “specialties” of their current implementation can be adopted with little effort.

The new process “DPF4VIEW.list” allows merging, stamping, and checking all files in a file list.

Conversion and PDF/A Creation

In addition to minor bug fixes and security updates, the application conversion can now handle the application version Corel Draw 2018 and PowerPoint Template (POT) files and create multiple target formats simultaneously.

The conversion can now process PDF XFA forms and transform them into normal PDFs.

The mail conversion can now process signed multipart MSG files.

In addition, PDF Longlife Suite (PDFLLS) has received an update to the basic Callas library to version 12.1 and now supports PDF 2.0, which means it can now check and adjust PDF/A-4 files.

Updated Infrastructure

Almost all third-party components that form the basis of our software have been updated to current versions. This provides a future-proof infrastructure for the coming years, which will continue to be updated regularly according to the German Federal Office for Information Security (BSI) instructions. (Apache Web Server 2.4.46, Tomcat 9.0.39, Java 11 compatibility, PostgreSQL 12.6, Perl 5.30, JBOSS 20).

Discontinuations

Until now, the editor GVim was delivered as part of our software. Since this has led to support cases that were difficult to resolve several times in recent years, we have removed the files from the standard delivery. However, installation packages are still available in Owncloud under /FM/Utilities.

ABBYY Finereader has discontinued support for version 10 of its OCR libraries. Customers with OCR recognition enabled must update to ABBYY 12.

The PDF tools: Pdfdck, fixfontbox, pdfsethyperlinks, pdfgxchft have not been used in our products for some time. With this release, they have also been removed from the standard scope of delivery.

The C907gribs and HPGLgribs converters have not been used in our products for some time. With this release, they have also been removed from the standard scope of delivery.

The DPF has been using file-based licensing since version 2.0, which significantly simplifies license management on the servers. With version 3.0, the old registry-based licenses are no longer supported after a four-year transition period.

SAP has discontinued support for the RFC (Remote Function Call) libraries on which the SEAL SAP tools are based (Sapcli). Instead, we now uniformly use jsapcli, which is based on Java JCO, for the coupling.

In the system status, the status display for SAP systems has been removed without replacement.
