[Wrapper-user] Dynamically passing arguments in wrapper.conf

[Silent K. <the...@gm...>]

Hi all,

I am a happy user of Java Service Wrapper, using it in several 
components. But I have a few queries regarding the use of the 
configuration file.

Is it possible to use environmental variables in the config file 
(wrapper.conf)? For example, one of the command line arguments that I am 
using is now of the form,

wrapper.java.additional.1=-Dbase=C:\installroot

But installroot is something that is decided by the user while 
installing the product. In such a case, is it possible to dynamically 
change the value of my argument in the configuration file? I can see two 
possible ways of doing it.

Option1: Set an environmental variable during installation. Something 
like MyProductInstallHome which points to C:\installroot. And I should 
be able to set the property in the configuration file as

wrapper.java.additional.2=-Dbase=%MyProductInstallHome%

Option2: Allow batch commands in the configuration file. So that I can 
do something like

wrapper.java.additional.2=-Dbase=%cd%\..

(what I mean here is that %cd% should give me the current directory, 
which in my case is C:\installroot\config and \.. will take me one level 
up so that I can get to the correct install root.

I hope I have been clear in my request so far.

Out of the two options I have stated above, is any of them possible? If 
at all possible, I would prefer the second option so that I do not have 
to rely on environmental variables.

Or I am completely off track here? Is there some other way to handle 
dynamic arguments?

Any pointers on this would be greatly appreciated.

Thanks,
SK
