Symptom: Reversing the calling order for the default and backup MIAWSservers (metoc.guide.net at GuideNet, and ran.apl.washington.edu at APL)causes incorrect server calls resulting in workflow system failure.Severity: Under normal usage this never happens, so it isn't a problem.However, if you are testing out the backup server specifically and alterthe run.bat to reflect this, an unexpected error may be caused.Reason for failure: System works correctly if "metoc" is listed as thedefault server and "ran" as the backup server in the run.bat. Initialcharacters from the default jws home page are parsed to see if theserver is up and performing correctly. If the servers are reversed,then the wrong character stream is used for comparison.Solution: We have discussed a ServerStatusServlet which would returnsome identifying server string when called. This servlet would alwaysload when the JWS is initialized. Failure of the servlet to return theproper string should cause MIAWS to consider the server as unresponsiveand to query an alternative server.

Not fixed as of 06.25.01 -- Since the fault only occurs whendevelopers are playing with the system, I think we'll defer fixing thisuntil the ServerStatusServlet is completed (should be soon)
