ExtenXLS Spreadsheet Server By Extentech, Inc.

ESS delivers realtime spreadsheet web services and automation in a technology bundle that includes the following technologies:

1) ExtenXLS version 6, the latest version of our best-of-breed Java Spreadsheet SDK. ExtenXLS:


gives developers total control over spreadsheet functionality
includes the most robust Excel-compatible Java spreadsheet SDK available
is trusted by hundreds of companies worldwide
has Enterprise, Social, and Web2.0-enabled functionality that controls:

change tracking and versioning
group-based security
JSON and XML output
user objects
concurrent multi-user collaborative access


2) The Sheetster Open Source Web Spreadsheet with:


GPL spreadsheet interface and data grid
clean, Object-Oriented, developer-friendly source code based on RESTful ExtenXLS API and the popular javascript toolkits: prototype.js, script.aculo.us
collaborative shared spreadsheets editable by multiple concurrent users
realtime data mapping from server-defined data sources
Web Spreadsheet (GPL)
high-performance web spreadsheet allows near-native spreadsheet size and performance
skinnable, web-based, multi-language MDI interface allows for editing and collaborating on multiple documents concurrently


3) CellBinder that


Maps realtime data from JDBC data sources to spreadsheets
Parameterizes queries and hyperlinks enable drilldown reporting
Includes multiple data sources and queries can be mapped into a single spreadsheet


4) R3S (Really Simple Spreadsheet Syndication) for publishing dynamic spreadsheet feeds
and patent-pending technology for publishing your live data mapped spreadsheets.

5) REST PADS


"Pluggable Application Data Services" GPL REST framework gives control and power to override and enhance built-in spreadsheet Web services with custom code.
Pluggable REST API, enables secure access to server objects through reliable REST urls.
Securely extend and integrate Java code within the Dexterity URL namespace.
Web2.0-friendly technology allows access of Dexterity functionality by non-Java developers including RUBY and .NET web developers.


6) Luminet-- An integrated lightweight Java Application Server


ESS can be run on any Java-compatible server, client, or virtualized environment
Turnkey app server with performance monitoring, built-in scheduler, shared secure database connection pooling and more.

7) Ontologically-enhanced Document Management System:


Categorizes and enhances documents with metadata adds value to your information.
Flexible and dynamic data schema that can store any type of information.
Presents documents with multiple collaborative and social features such as blogs, RSS feeds, attachments, comments and more.
Workgroup-based security and document types gives total control over access to documents






Using ExtenXLS Spreadsheet Server, developers and power users can visually define queries and data sources and drag and drop fields onto a Java swing spreadsheet to define data mappings and then with a single click, deploy to the Sheetster web spreadsheet interface for access by end-users.

Using the intuitive REST API, developers can also access calculated spreadsheet cells from their SOA or web services consuming applications.

The REST API is built upon an extensible, pluggable architecture called "PADS" -- Pluggable Application Data Services.

REST PADS allows developers to enhance and extend the functionality of Dexterity Spreadsheet Server by implementing simple interface in their Java objects, and then dropping the compiled classes into a plugins directory. Dexterity Spreadsheet Server can then be instructed to reload plugin classes -- without restarting the server or interrupting application services -- and the new functionality is available instantly through the RESTful URL.

In conjunction with the full power of the ExtenXLS Spreadsheet SDK, fine-grained role-based security and fully brandable Web spreadsheet interface, the Spreadsheet Server will become an indispensible and ubiquitous addition to your application infrastructure.


For example, the application can be mapped into a portal or other website namespace to provide spreadsheet reports to users, with fresh data mapped into the output spreadsheet file.

ExtenXLS Spreadsheet Server includes the Open Source web spreadsheet, Sheetster 2.0 -- which means you can embed the fully functional Web spreadsheet (with the live data mapping) in your Web applications.

All published spreadsheets are accessible through a REST API as described here:

The REST API enables very powerful applications to be built using Web2.0 technologies.

For example, mapping data to a spreadsheet cell as a Web service has the following immediate benefits:
A formula cell can be exposed as a web service to perform calculations based on realtime data
The formula can be edited and maintained by spreadsheet-savvy end-users
The developer does not have to rewrite the formula logic in Java or C++
There is no maintenance or testing required to deploy the business logic -- if it works in the spreadsheet it will work as a service
The business user can be involved in future iterations of the business logic, or in successively more advanced use cases
ExtenXLS Spreadsheet Server is a revolutionary step in the history of spreadsheets as well as application development.

Extentech Inc. continues its proud tradition of leadership in this area.
