[Wrapper-user] Wrapper stdout redirection in realtime

[Daniel M. <dan...@be...>]

I have a C#/.NET 2.0 GUI application I use as a front end to a Java
application I have developed. Traditionally, this Java app was invoked
via a DOS batch script which constructed classpaths and executed the
Java command directly. Within the GUI application, I was able to invoke
the batch script and redirect stdout and stderr to capture the Java
app's output in realtime and display it to the user. In order to gain
more control over the indirectly-invoked Java app, I have encapsulated
it in the Service Wrapper, to good effect (For instance, I can now
capture the pid of the Java/wrapper instance and kill it from the C#
application). I realize this isn't necessarily the intent of the
wrapper, but launch4j can't do all the classpath stuff I need, and I
don't have access to an exe4j license. So bear with me...

My problem is this: since I modified the batch script to invoke the
wrapper rather than the Java command itself to launch the application,
my C# application no longer gets realtime output from stdout/stderr when
the wrapper is running. The C# code itself hasn't changed; in fact,
output from the batch script itself gets redirected properly and in
realtime as before. It's just the wrapper output which is funky: it
doesn't actually get passed back to stdout until it's completely run its
course.=20

Any ideas what could be causing this? Obviously it's redirecting
somewhat properly, because I do eventually get the stdout stream... but
not until the end of the wrapper execution. I searched and couldn't find
any configuration properties related to output redirection.

Heeeelllp! :)
