Open Source Alternatives to LiveCycle Data Services

LCDS is a great solution for Flex/Java enterprise projects, but it's not the only one

Clear Tookit on Ulitzer

Development of enterprise Flex/Java rich Internet applications benefits from using automated data integration solutions and productivity tools.

Currently Adobe offers LiveCycle Data Services ES2 (LCDS) and open source BlazeDS 3.

While LCDS is certainly a great piece of software for those who are looking to support thousands of concurrent users via the most efficient communication protocols, its high licensing cost makes LCDS unaffordable for the vast majority of the enterprise applications let alone small businesses and startups.

If you are looking for an alternative solution for integrating Flex and Java EE layers, consider using GraniteDS, WebOrb, and Clear Toolkit.

The first two products offer their own implementation of the AMF protocol, and Clear Toolkit uses the AMF libraries that come with BlazeDS . If you are looking for an open source implementation of the Real-Time Messaging Protocol (RTMP), the Red5 server (currently in version 0.7) may be your option.

The feature matrix below compares LCDS, BlazeDS, and open source Clear Toolkit. This feature matrix was created using the data from the LCDS/BlazeDS comparison chart published by Adobe .

The current version of Clear Toolkit is 3.2.1. The features that are currently not available but will be implemented in Clear Toolkit version 4 by the end of 2010 are marked as v4 in the chart below.

Disclaimer. I'm one of the creators of Clear Toolkit. But if the owners of GraniteDS, WebOrb, and Red5 would like to be listed here, please let me know, and I'll gladly update this feature matrix.

*   Farata Systems can develop an NIO-based BlazeDS solution on a per-customer basis under a separate consulting agreement. Read and watch performance tests of our high concurrency Jetty/NIO/BlazeDS solution at http://flex.sys-con.com/node/720304

** Currently, Farata Systems is working on a solution to introduce the model-driven development to Clear Toolkit.

*** LCDS offers advanced server-side PDF generation. Clear Toolkit components support PDF generation on the client (WYSIWYG), but does not support working with forms.

**** Adobe doesn't publish the cost of the LCDS ES2 license. The price listed here is based on the data shared by current users whose employers allegedly paid (read the comments to the following blog post of Adobe LCDS/BlazeDS Product Manager).

I'll be demoing Clear Toolkit in action at the Flash and The City conference in May in New York City. If you'll be in town on May 17, consider attending our hands-on master class on the modularization of Flex applications.

Every organization is facing their own Digital Transformation as they attempt to stay ahead of the competition, or worse, just keep up. Each new opportunity, whether embracing machine learning, IoT, or a cloud migration, seems to bring new development, deployment, and management models. The results are more diverse and federated computing models than any time in our history.

Digital Transformation is much more than a buzzword. The radical shift to digital mechanisms for almost every process is evident across all industries and verticals. This is often especially true in financial services, where the legacy environment is many times unable to keep up with the rapidly shifting demands of the consumer. The constant pressure to provide complete, omnichannel delivery of customer-facing solutions to meet both regulatory and customer demands is putting enormous pressure on...
IoT is rapidly becoming mainstream as more and more investments are made into the platforms and technology. As this movement continues to expand and gain momentum it creates a massive wall of noise that can be difficult to sift through. Unfortunately, this inevitably makes IoT less approachable for people to get started with and can hamper efforts to integrate this key technology into your own portfolio. There are so many connected products already in place today with many hundreds more on the h...
The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications.
