I have installed Netweaver 7.4 using the "Process Integration and Orchestration Package". Then followed up with the post processing including the PO wizard in nwa as described in the help. The installation and the wizard did not report any errors. Everything seems to have worked.
This system is a java only stack.
In the runtime workbench, the Integration engine is flagged as red. When clicked, it shows the above error. Details show a very long stack trace the end of which is:
Message: Neither messager server nor application server are defined for system ---
Stacktrace:

You will notice the last thing it seems to do mentions "R3Sytem". There are no JCO connections defined; there is no abap stack.
I have followed the following notes:
Note 764176 - Manual correction of XI content in SLD
Note 1031321 - Self-Registration of Adapter Engine and RWB fails
Note 1117249 - Incomplete Registration of PI components in SLD
and also:
...but the problem remains.
I have encountered a similar problem on a dual stack and the notes above did help. However this is a single stack 7.4 java and they do not seem to apply.
Any suggestions welcome.
