Re: [Wrapper-user] Runtime exec in my app fails when app is installed as a service

[Hubert F. <Hub...@ab...>]

Hi,

If possible try to avoid using the redirector from a service. You won't =
get lucky with this.
One of your problems is, that services running with localsystem account =
cannot access the the redirector (network).=20
-You would have to establisch a "null session share" to the target =
machine. That't means absolutely no security. Otherwise=20
you must run the service with a dedicated user account.=20
-Your service has to be dependant on Windows Server service and Workstation=
 service  to wait for the network first.
-You have problems mapping the drive while a user is logged in.
-You loose that drive as soon as the user logs out.
-You'd have to enumerate the user shares to find the relation from mapped =
network drive to the share name. If you cannot avoid it, you should use
UNC names instead of drive letters.

I would do it in another way, if possible.

Hi,

My Java app (Jar1.MainClass) calls Rumtime.exec() to execute another java
app (jar2.MainClass). This works when I run the app from the command line
(hence I would assume my Rumtime.exec() is working properly). It
successfully execs the new process.

But when I wrap the app (inside the java service wrapper, the app (
jar1.MainClass) starts up fine, but the Rumtime.exec() fails. My app gets =
a
NoClassDefFoundError on the call to the Runtime.exec() - Its not able to
find the main class of the process that my App is trying to exec(). What
intrigues me if how does wrapping my app in a service differ from running
the app from the command line. The service is not failing since it runs my
app (jar1.MainClass), but somehow it fails on the exec.

I have tried the following:
- Since my path includes a network drive, I thought the problem might be
related to security - so I run the service as a permissioned user instead =
of
the default system user.
- Since this could be a classpath problem I added the jar to wrapper's
classpath in the conf file.

I searched the website, but could not find something that would help me
solve the problem. It would be great if any of you have a suggestion for
this.

Thanks
