Hi all,

I have some problems with RAP in my productive enviroment.
I'm using RAP 1.2 in productive and 1.3 in test envir.
App server is JBoss 5.1, OS RedHat, java 1.6.0_07

I look at the tomcat status page and i see many hanged sessions, some
with a Callback others without.

See http://ge.tt/3QuToD1

In my test environment I have tried to add the parameter
-Dorg.eclipse.equinox.http.jetty.context.sessioninactiveinte rval=1200

but the sessions aren't invalidated (in test i have only 1 request of
type GET /rap/xlnet?
nocache=1300729646192&custom_service_handler=org.eclipse .rwt.internal.lifecycle.UICallBackServiceHandler
HTTP/1.1)

Any hints here?
Thank you very much

Hi Elvis,
the blocked UICallBack request will prevent the session from
invalidation (timeout). This happens if you have a running UICallBack
all the time (enabled on application start up and never deactivated).
That's why we suggest to activate the UICallBack only when you really
needed and deactivate it afterwards.
HTH,
Ivan

Hi Ivan,

thank you for your response.
I haven't explicit opened a UICallback.

My application is single-sourced with the RCP one.
I have many Jobs and UIJobs for client operations.

I have a JobFactory implemented in my RAP fragment that runs my jobs as
follows http://paste.ubuntu.com/583710/


Kindly

1.4 is not an option at the moment... :(
It's a productive environment.

Any other hint?

Hi Elvis,
maybe you ran into this bug:
319224: [UICallback] Hanging UICallback request at startup
https://bugs.eclipse.org/bugs/show_bug.cgi?id=319224
It will be good if you provide a snippet to reliable reproduce this
UICallBack hang. If you have such, please attach it to the bug above.
Thanks,
Ivan

Hi Ivan,

i can't reproduce exactly the bug (for now).
it seems a random situation.

the uicallback hanged isn't started at startup... i'm trying to
invenstigate better.
What i can say for sure is that the problem exists in 1.2 and 1.3.

what situations could cause an uicallback?
maybe accessing ui resources in a non-ui job?
can be something i'm doing wrong?

Hi Ivan,

I have news here!
I have hanged a session ;)

I have a File > Exit menu entry created as
ActionFactory.QUIT.create(window);

After doing my tests I select File > Exit and the session hanged with:
709070 ms 0 KB 0 KB 192.168.x.xx server901 GET /rap/
xlnet?
nocache=1300800007775&custom_service_handler=org.eclipse .rwt.internal.lifecycle.UICallBackServiceHandler
HTTP/1.1

In the broswer after a F5 press i have the following:

Is really required a File > Exit menu entry for RAP clients?

Hope this helps.

Hi Elvis,
this will really help us to debug it. Please file a bugzilla with a
self-running snippet to reproduce it.
Thanks,

Ok, Ivan. I'll open a bug and report the number here.
What would you suggest me as workaround?

Removing the File > Exit menu option is good practice?
Can I catch the exception in some manner and avoiding the uicallback hang?

I ask you cause if i have many sessions hanging the server crashes... :(

Kindly

Elvis, without an investigation of the problem I couldn't say anything.
But for a good investigation we need a way to reproduce it :-)
Best,
Ivan

Hi Ivan,

I have resolved my issue :D (therefore virtually marking this thread as
[SOLVED]!)

I try to explain here as reference (sorry for bad english).

My single-sourced app is based on persectives (one function is a
perspective, i.ex. customers management is a perspective, orders
management another and so on).
The user switches perspectives using menu items.
The standard éperspective switcher is disabled.
Before opening the requested perspective I save and close the perspective
using the method:

(...).getActiveWorkbenchWindow().getActivePage().close()

This throwed an exception (cannot dispose active part, if i correctly
remember) that I have always ignored (blame on me).

That situation caused another exception when closing the application, the
Widget disposed too early exception (always ignored too).

In RAP that caused the UICallback to hang infinitely.

Ihave changed the 'Switch perspective action' in
(...).getActiveWorkbenchWindow().getActivePage().closeAllPer spectives
(true,true);
and now I haven't exceptions in switching perspective nor exiting from my
app, thus no uicallback hanging there.

HTH someone else, thank you Ivan for your time
Kindly

Elvis Dominguez
