Description
From a user:
In Processing section there are may climate extreme indices (WPS for simple indices) but when I tried to calculate some simple indices using example files from KNMI I’ve got “Error: SAXException: Premature end of file. for URL http://climate4impact.eu/impactportal/WPS?OUTPUT=/pywps-142661205115.xml”

Maybe a duplicate of bug #159?

This might solve it, in impactportal.wps.WebProcessingInterface.java, line 451, method monitorProcess:
/*
* It seems that the statuslocation XML file is sometimes not completely written by PyWPS, or not immediately available after the process has been executed.
* Solution: Retry to read the XML file a couple of times until we have a good result. *
*/
int maximumTries = 10;
boolean success = false;
do{
maximumTries--;
try{
b.parse(new URL(statusLocation));
success = true;
}catch(SAXException s){
Debug.errprintln("Statuslocation does not contain valid XML, retrying..., attempts left: "+maximumTries);
Thread.sleep(200);
if(maximumTries == 0){
throw s;
}
}
}while(maximumTries>0 && success == false);
