OFBiz 13.07 - Communication error with the client while processing the request

[ericnk]

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...

Hi Ashish,

Then we should mention it. The tutorial  says only <<This tutorial is intended to be used with the latest SVN revision. It will /not/ work with
Release 4.>>

Or better update it ;)

Hi Jacques, Ashish

I have to check the authenticity and infect thinking to have a fresh and new light weight tutorial for beginners. Its been a long time we haven't done any major changes here, I have recently revisited it and think it needs overhaul.

Thanks and Regards

I had the same error message and a blank screen.
The reason was a typo in the page-reference
of the screen component.

<view-map name="xxx" type="screen"
page="component://myComponent/widget/xxx.xml">

If the valid name is XXX.xml instead of xxx.xml
this message occures (maybe it occoures also in other cases,
but with this typo I can produce a blank screen).

If the error (bug) still exists, please feel free to create a JIRA issue.

Best regards,

Pierre Smits
