Running tomcat from my code
Hello. How can i start and stop tomcat from my own code? Something like startTomcat() and stopTomcat() methods, which in its turn calls to some of tomcat methods. (There is a problem that doesn't allow me to simply calls *.bat(*.sh) files). tomcat version = 6.0.13. Thanks for your work.

The main question is:
- Of which type is the OP's application-code? Java? C? C++? Lisp? ;)
But most important.
What is the OP trying to achieve? It might well be that there's a
smarter solution to the original request.

Can you elaborate a bit on the above, in just 2 lines ?
Don't go too deep in Java, or I would be lost.
Is it like :
You start a JVM with your own code, then your code starts a thread
running Tomcat's bootstrap.jar, and Tomcat then starts its own threads
etc.. Because your application started the main Tomcat thread, it has
control over it ?

Not in so many words, Pan Mikolaj, but the general tone of the question
kind of implied that.
Which is why I felt qualified enough to give a first tentative answer.
Usually, I do not dare, because they are way over my head.
Fortunately, there are real experts here to correct my mistakes.

I did not think I would find a 2-line answer in Google.
And apparently I was right. Thanks anyway for suggesting it.
Ok, so it's apparently a lot more complicated than what I suggested.
Why did I expect a 2-line answer with anything to do with Java anyway,
silly me.
;-)
(yes, I know, it depends how long the lines are..)
Anyway, to get back to the OP's question thus, that was not really a
simple answer to his problem, was it ?

You have to be lost before you can be found:

Use JMX for such purpose.

You can embed Tomcat in your code as well.
It depends what your requirements are.

You can stop the whole Tomcat, by connecting to the "shutdown port" (see
server.xml) and sending the magic shutdown string defined there.
You can probably stop and start individual *applications* within Tomcat
programmatically, since that is what the Manager application does.
Since that application's source code is available, you can peek in it to
see how it works.
But to start Tomcat, I believe the only way is to start the JVM in which
Tomcat runs, and for that you probably do need to issue an
operating-system level command.
