Running Java applications as a service - startup error captures? -

-

i'm in arduous process of trying upgrade couple of our servers use current version of application installed on , i've gotten bit stuck. i've gotten replaced , have narrowed issue down 1 .jar file. if use new version of specific file, can not service start, , using old version (and new version of every other file), runs fine.

when try start service message: could not start <service> service on local computer. service did not return error. internal windows error or internal service error.

i've looked in event viewer, , has these entries every time try start it:

<service> has started

could not find service start class

<service> has failed start

is there place else can might able give bit more information on why it's failing start?

we using 'javaservice' utility create windows process. server running jboss.

edit: have determined not issue sql database did of upgrades between versions. still can't start new .jar, , old .jar still works.

thanks!

you can't execute java application service. windows services implement specific interface java.exe or javaw.com not. need wrapper implement functionality. 1 such wrapper http://wrapper.tanukisoftware.org.
