[Wrapper-user] Runtime.exec() problem

[Adrian M. <ama...@ge...>]

Hello everyone,

I have a Java application that uses Runtime.exec() to start another .NET
app. This works just fine when running my program 'standalone'.
The problem arises when I use the wrapper to install my Java app as a
service: Runtime.exec() executes ok, the .NET app is launched and it
seems to work without issues up to about one and a half / two minutes
into execution, where it freezes and is seen as 'not responding' by windows.

I have browsed through the mailing lists archives and seen some problems
with exec() related to the access to network drives or error dialog
messages that are not displayed on screen, but I don't think any of this
applies to me. Of course I considered that the problem may be caused by
the .NET app running as SYSTEM, but (and I find this quite puzzling)
after the freeze if I stop the java service or just plain kill the java
process the .NET app resumes normal execution as if nothing had happened
and has no more problems.

A couple more details:

- My java app has no GUI; the .NET one does.
- The java service seems to keep running in normal fashion after the
.NET app hangs.
- (Don't know if this is relevant) The .NET app acts as client to some
web services. It invokes them some times without any apparent issues
before hanging.

If anyone could point me in the right direction where to look regarding
this it would be greatly appreciated (I'm quite lost here).

Many thanks.

Adrián.
