Re: [Wrapper-user] Converting Java Application into Windows Service ?

Almond,
You need to read the documentation again :-)
http://wrapper.tanukisoftware.org/doc/english/integrate.html
Most likely method #1 will work for you:
http://wrapper.tanukisoftware.org/doc/english/integrate-simple-win.html
There were a few problems with what you said below:
1) You should start with a clean directory and copy the required Wrapper
files into your
application rather than the other way around. There are some things
that you will not
need such as the wrappertest.jar file.
2) You should create your wrapper.conf file based on the template file:
WRAPPER_HOME/src/conf/wrapper.conf.in rather than using
WRAPPER_HOME/conf/wrapper.conf.
3) As specified in the documentation and in the wrapper.conf file,
the wrapper.java.mainclass property is used to specify the main class
passed to the JVM. In most cases however, this is not your application's
main class. The Wrapper has some code which must be initialized in the
JVM first. This is covered clearly in the above documentation. Try this:
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp
Your main method is then specified as the first parameter to the above main
class.
wrapper.app.parameter.1=<YourMainClass>
4) From the output that you sent however, it looks like your main class
starts, prints a startup message, a shutdown message and then exits.
Even if you do all of the above correctly, your application will still quit
immediately because your main method does not appear to be designed
to stay running. Running your class standalone in Java would have the
same effect.
The Wrapper works correctly in cases like this. But from your post, it
sounds like you are expecting that the JVM stay running. Your application
needs to start at least one non-daemon thread within the JVM that does not
terminate. When all such threads have terminated, the JVM things the
application has completed and the JVM will exit.
5) When you are still trying to get things working, I suggest running the
application in a console window using TestWrapper.bat rather than running
as a service. It is easier to see what is happening. Once that is all
working,
THEN, you should try it as a service.
6) Not required, but I suggest copying your bat files out of the
WRAPPER_HOME/src/bin and then naming them after your application.
Let me know if you have more questions...After checking out the docs of
course.
Cheers,
Leif
