Oops, it's too hard for me! Three days ago it has been the first time I installed an apache tomcat, and I have no experience about it or
java.
So probably I set up the service wrong and I would like to explain what I did:
- after I assured, that Tomcat starts right on my Windows server with the script "startup.bat", I decided to run it as a service.
So I read the documentation
http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html and found that the script "service.bat" should install it as a service. But the service didn't start up, it makes an service specific error 0 ...
it's silly:
When writing this answer I did the same as yesterday, and now the script works and the service even works fine. Don't know why, but yesterday it didn't...
So thank you, for spiritual help!
