Restarting Tomcat & Threads
Hi,
I would like to ask on strange behavior Im experiencing.
I have webapp that connects to Lotus Notes periodically(every 1 minute).
For this I have class that implements Runnable that takes care about
connection itself.
Im starting this using basic :
Thread t = new Thread(MyClassImplementingRunnable);
t.start();
I have noticed that when I kill Tomcat (shut down its service) then after
start this thread is started
automatically (I can see messages about connecting to Lotus in log when I
didnt start anything).
Is this usual behavior?
Is there any was for threads "not to start automatically" ?
Im beginner with Tomcat so excuse my lack of knowledge.
Thanks
Zbynek

The tomcat code, by itself, has no reason to connect to Lotus.
So if something connects to Lotus, it must be in the code of your application.
But you say above that you do not do that.
So something above is wrong.

Maybe you are running the Lotus connector through a servlet that defines
"load-on-startup"?

So you have to go through that web interface to start the lotus thread,
but you're not doing that and the thread is still starting up?
Sounds like the method that starts the thread is being called from
somewhere that you're not expecting. Any chance it's being fired off
from a timer or a listener?

- How do you kill Tomcat ?
I stop its service.
- You say "after start" and "I didnt [sic] start anything" in the same
sentence; you're contradicting yourself.
I start Tomcat which starts my webapp but connection to Lotus is started
separatedlly.
= I start my webapp but do not start "Lotus connector".
1) My code(thread) could not be executed unless I start it via web
interface.Which I dont.
2) Im talking about log from log4j so it is log of my application.No one
else's.

You say "after start" and "I didnt [sic] start anything" in the same
sentence; you're contradicting yourself.
Tomcat knows nothing about your thread or the connection to Lotus, so one
of two things is happening:
1) Your code is being executed, you just aren't aware of it.
2) Something else is connecting to Lotus and you're mistaking that for your
code.
