Subject OFBiz 13.07 - Communication error with the client while processing the request
Date Sat, 19 Apr 2014 15:20:29 GMT
Hi,

I'm trying to work through the tutorial at ...

https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Tutorial+-+A+Beginners+Development+Guide#OFBizTutorial-ABeginnersDevelopmentGuide-CreatingPracticeApplication(HelloWorld...)

But, so far I haven't been able to get a successful result.  Every time 
I try to display the result page, I get nothing.  Just a blank web 
page.  In the log, it seems like the request is being process normally, 
except that the following warning message comes up....

ControlServlet.java:220:WARN ] Communication error with the client while 
processing the request: /practice/control/person

I'm assuming that this warning message is indicating there was a problem 
communicating back to the browser.  Googling the message, I saw 
discussions that this message occurs when the connection to the browser 
is lost, for whatever reason.


Here is the portion of log that appears when the request is submitted...

Is there anyone that can offer guidance or suggestions as to why this is 
happening and how to solve it?  It would be much appreciated.  Thanks.
