Summary

When did I get this?
I have a fresh installation of SOA suite on my stupid Vista laptop.
I had a hard time getting this into it in the first place.
I was damn happy getting this into it and I though wow here I go.
But damn stupid thing, after re-starting my system I could not get the SOA suite working.
I capture what I did to get this wonderful thing working.
What is this error and why I write this?
The first bolt I got was this
“An unknown OPMN error has occurred”
“Error connecting to OPMN (is it running?): Connection refused: connect”
This was when I tried to start SOA suite from the “start SOA suite” from start menu.
