No configured connection to host 'localhost' #152

Closed anarak closed 5 years ago

anarak commented 7 years ago

When creating a plot using VisIt viz service, I got the following error:

Caused by: java.lang.Exception: ConnectionVizService error: No configured connection to host "localhost".
    at org.eclipse.eavp.viz.service.connections.ConnectionVizService.createPlot(ConnectionVizService.java:91)

This error is thrown because a) connectionByHost in VizConnectionManager is called before it's initialized, or b) connectionByHost never meant to contain/recognize 'localhost' as its member element, as implementation of getConnectionsForHost allows for connectionByHost to be null. But then, the next stack call throws this error saying it can't be null.

Did anyone try to consume EAVP's VisIt viz service before?

Solution to this would be having default connection values preset programmatically before calling getConnectionsForHost.

I'm looking at this now. Will you post you full stack trace please? Also, what branch are you using?

Sorry, I don't have any additional insights to share. If I was you, I would run it through the debugger and see what the value of host is at ConnectionVizService.java:84.

@SmithRWORNL will probably have to fix this.

anarak commented 7 years ago

The value of host is null at ConnectionVizService.java:82 but then it's reassigned to 'localhost' at ConnectionVizService.java:84. I already debugged this issue and I explained its cause in the description.

VisIt will no longer be supported in 0.3
