Reliable/Safety-critical JAVA middleware - Best practices

Question

What are the best practices for implementing reliable and safety-critical Java middleware?

Answer 1

The following properties come into my mind:

• You might use Real-time Java for time-critical operations
• Build fault tolerance and lots of retry into the communication if you have a proprietary protocol
• You might consider a SOAP provider with WS-Reliability extension for example.
• Have an industrial PC and hardware, not a desktop one.
• You might want to use watchdogs on both ends and for example stop/pause the mechanical movements
