CapabilityMap returned a null media type
I've developed a portal using spring portal mvc and deployed it on jetspeed
portal server. Everything was fine until recently (say for the past 1
month), when we try to access the portal it gives "Null media Type" error on
the browser.
My portal front page (index page) has some images and a flash animation on
it.
One more thing is i modified portal features from jetspeed (i modified
header.vm, footer.vm etc) to arrive at my desired page layout. It works
perfectly fine and suddeenly it gives the following error. Once we receive
this error, only way to get out of it is to restart the server. Since we are
going to release the alpha very soon, i need to fix this error at the
earliest. So, any help/clue in this regard is highly appreciable.
The error thrown on the browser is as below:
********************************

Can anybody tell me what is causing this error? If you need any further info
on the code/architecture, pls tell me. I ready to provide the info.
Please help me to solve this error at the earliest.
Thanks so much.

Sounds like your MySQL connection is timing out due to inactivity.
I used to believe there was a MySQL JDBC autoreconnect property you
can use for ex:
jdbc:mysql://localhost/test?autoReconnect=true
I think this setting may be deprecated.
I just tested it and it does not work for me. I killed the connection
using MySQL Administrator, and this setting had no effect.
Im using 5.1.6 of the MySQL Connector, and MySQL version 5.0.67
There are two my.cnf settings you can add to your My SQL
configuration. Look at "interactive-timeout" and "wait-timeout"
settings.
Or you can set that via the MySQL Admin program under Options-
>Advanced Networking. Set it to a value greater than the longest
period of interactivity
It defaults to 28800, which is 8 hours. Try some value greater than
your longest inactivity, say a long weekend
# 3 days
interactive-timeout=259200
wait-timeout=259200
I think a better solution would be to shorten the timeout of the JDBC
connection pool on the Jetspeed side (OJB), I will look into this,
but for now the settings above should solve the problem

Thanks so much David for the help.
I did the necessary changes you mentioned. Hope i won't get that problem
again.
Please let me know how to set the timeout period of JDBC Connection.
Thanks a lot. I appreciate your help.

Re: CapabilityMap returned a null media type
Posted by laxmiraghu <la...@yahoo.com>.
Thanks VIvek.
Actaully the error appears in firefox as well. SO, it may not be IE issue
alone.
I checked the jetspeed.log file. IT's empty. May be, next time that error
occurs, i need to watch that file. WE just restarted the server today
evening.
Actually i changed the layout files of jetspeed - header.vm, footer.vm,
layout.vm and decorator.vm files of jetspeed to arrive at my desired layout.
Will there be something causing this error? If need be, i can send those
files to you.
Thanks again. IF you have any clue, pls mention. Thanks for helping again. I
need to resolve this error by next MOnday.

Hi
I am talking about logs at this location "webapps/jetspeed/logs"
In jetspeed 2.1.3, there is no client configuration of IE 7. so there
can be issue for IE 7.
I am little bit surprise with you situation, as it seems to be difficult
to under-stand, it is giving null pointer in CapabilityMap, once server
is running.
I would say check you log file, there would be something there and
serving images is not an issue.

Re: CapabilityMap returned a null media type

Thanks again VIvek.
IN /usr/lcoal/Jetspeed-2.1.3/logs folder, i don't see any jetspeed.log. I
see admin*.log, catalina*.log, localhost*.log, host-manager*.log,
manager*.log and catalina.out.
I checked in catalina.out, but when that error occurs there is no log
content generated on catalina.out.
ONe more thing - this may help in identifying the issue.
The portal works just fine after restart for sometime. After that that error
pops up that too on some machines only. In my office, we are still able to
access but outside our office, when somebody accesses it, it gives that
error. For some it works, for some it doesn't. We tried it on IE
(InternetExplorer) and Firefox.
The portal i developed is a social networking portal which deals with lot of
images. When i try sending images say around 75 images, it will send the
images say upto 55-57 images, and then end up in error message
(SocketTimeoutException). I experienced this error in firefox after the
above mentioned error. IT's again a guess. Not sure what's causing the error
actually.
Can you please help me solve the error? THank you.

Hi
In that case there can be only two things now
Jetspeed database in not populated correctly or you are not able to
connect to data.
There is some there while starting the jetspeed.
Please check jetspeed.log under /logs folder of jetspeed.

Re: CapabilityMap returned a null media type
Posted by laxmiraghu <la...@yahoo.com>.
Thanks Vivek for the quick reply.
I installed Jetspeed in /usr/local/Jetspeed-2.1.3/shared/lib folder, i found
the following:
jetspeed-api-2.1.3.jar
jetspeed-commons-2.1.3.jar
mysql-connector-java-5.1.6-bin.jar
pluto-1.0.1.jar
portals-bridges-common-1.0.4.jar
portlet-api-1.0.jar
And my application's /WEB-INF/lib folder doesn't have any jars related to
jetspeed.
What is it that causing the error? Please help.
IF i go to /usr/local/Jetspeed-2.1.3/

Hi
Please check you portlet application lib, It* should not* contain
jetspeed-common or jetspeed-api jars.
Jetspeed-common and api should be provided via shared lib.
