Cohesions 2.0 Technical Overview

Cohesions 2.0 is shipped as a set of Java class libraries and APIs.

Supported Operating Systems and Java Virtual Machines
Cohesions 2.0 supports the use of the Javasoft JDK/JRE 1.4, minimum release level 1.4.2_02 on the following platforms:
Sun Solaris 9.0 (SPARC)
Red Hat Linux AS/ES 2.1 (kernel 2.4.9)

  Support for other environments is subject to customer demand.

Supported carrier protocols
Cohesions 2.0 supports the following carrier protocols for coordination messages:
Java Remote Method Invocation (RMI)
Java RMI over T3 (BEA WebLogic 8.1 only)
SOAP over HTTP/HTTPS
  Application messages are not restricted to any specific carrier protocol.

Supported application containers
Applications may be freestanding or hosted in Web Service or J2EE containers (including support for applications using EJBs). Cohesions 2.0 supports the following application containers:
BEA Weblogic 8.1
IBM Webshpere 5.1 / Axis 1.1
Cape Clear Server 4.0
Oracle 9iAS Release 2 (minimum build 9.0.3)
Apache Tomcat 4.1 / Axis 1.1
  Further application container support is planned for future releases.

Database support
Cohesions 2.0 requires a Java Database Connectivity (JDBC) 1.0 accessible relational database that supports standard SQL and local transactional features.
Oracle 9i Release 2 (minimum build 9.2.0.1.0)
  Further database support is planned for future releases.

Compliance with business transaction standards
Cohesions implements the following transaction protocols:

OASIS Business Transaction Protocol (BTP) 1.0 Committee Specification

WS-Coordination and WS-Transaction (WS-C+T) 1.0 draft specifications* published by BEA, Microsoft & IBM
   
* As these specifications are only licensed for research and analysis, and have not been put before any standards body, Choreology is unable to make its working implementation of WS-C+T available for commercial use. We maintain an active interest in the latest versions of these specifications - WS-AT and WS-BA - as they progress through the standardization process.
