HttpProcessor Problem - Starting background thread

2004-04-16 Thread Namasivayam, Sudhakar (Cognizant)
Hi,
   My webapp was running fine for 2 days when suddenly, a static thread had stopped... 
this thread should be always alive 
I searched the logs but find only this entry

2004-04-16 13:43:41 HttpProcessor[8080][6] Starting background thread

What does this mean? Please can any  tell me the scenarios it could happen ?? 
Can i do some thing before or after  this event is called, like pesisting the 
objects???

I m using Tomcat standalone running on port 8080. 

Linux  +  tomcat 4.0.4 + JDK 1.4


Thanks in advance,
sudhakar

usually when i start/stop the thread i find these

Hi,

2004-04-16 13:43:41 HttpProcessor[8080][6] Starting background thread

What does this mean? Please can any  tell me the scenarios it could
happen

It means there was sufficient concurrent load on the server that it
needed to start another processing threads, and that less than the
maximum number of threads for connector were already started, so it went
ahead and started another.

Can i do some thing before or after  this event is called, like
pesisting
the objects???

Only if you want to write some very tomcat-specific code, and you don't.
This is not a highly significant event in terms of resources, just
another thread, and the 6th (or 7th) one at that so it's not even a high
load scenario.

Hi,
It's funny that you wrote your own thread manager and have to ask this
question.

No, tomcat cannot destroy all your threads and objects referred to from
these threads.  Tomcat can only destroy daemon threads for you.  You
need to take care of the rest by yourself.  A ServletContextListener's
contextDestroyed method is an excellent place to do this: shut down your
thread manager and all your threads, otherwise tomcat's JVM process will
not die.

hi all,
   I have a Thread mgr which will create a thread. No if i Start
and
Stop the Tomcat, The older mgr object seems to be still in the JVM and
this
causes a problem because a new mgr is created and i have two copies of
threads running simultaneously..
  Can any one tell me whether all objects will be destroyed if i do
start and stop of tomcat? Should i do anything in the  Context

destroyed but the thread seems to be alive?

Hi,

 No luck in that mailing list :(  May be i thought this might have to do some thing 
with tomcat... 

I am using the default RequestPrcessor only. I m using the default package of struts!

Hi,
You might have more luck with this in the struts-user mailing list.

Are you using a custom request processor?  If so did you extend
org.apache.struts.action.RequestProcessor or
org.apache.struts.tiles.TilesRequestProcessor?

Hi all,

This error happens only in Tomcat 4.0  and not Tomcat 5.0.19 in Linux 7.0.
Am i missing any library files? I have put the latest library files. I did
find similar mail in the struts archives but no response to that...  Or is
this the problem with my manager webapp?

  I do not get Class cast exception message when i stop and start the
webapp. Only when a action is invoked this exception occurs!!
Both the times( stop-start   and   action.do ) it is trying to get the same
RequestProcessor object but the second time it throws an error.

If i insert a try catch block in the ActionServlet class,it works fine...
Can any one explain me why this exception occurs?
I did  verify that  getServletContext().getAttribute(key);  in
ActionServlet.java:855 returns a RequestProcessor object.
Pls find the log and my server.xml at the end of the mail.

Thanks in advance,

2004-03-17 Thread Namasivayam, Sudhakar (Cognizant)
Hi all,
   I deployed my webapp using the war file biult using ant 1.6.  The webapp is 
deployed and works well. But when i stop and atart again through the manager I get the 
exception Zip file closed error.  But removing and installing again works well...  
What could be posssible cause???
I dont  get this error if i unpack the war and deploy.  But tomcat 4.0.4 under linux  
(jdk 1.4)  does not unpack by default but creates a context.   Reload also works well. 
  Is there any way to unpack the war by default   This issue does not arise in 
tomcat 5.0. But i need to use 4.0 :(

Config : tomcat 4.0.4 ,Struts 1.1, jdk1.4


Thanks in advance,
