Re: [Wrapper-user] Cannot bring up a browser

Senthil,
    One other thing.  Unless you specify an account to run as, the 
Wrapper runs as a service
using the default SYSTEM user.  This means that any child processes will 
also be run as
the system user.   Back when I was playing with Excel, I was having a 
problem launching
Excel as the SYSTEM user because Excel likes to bring up a configuration 
wizard when
it is launched for the first time for a given user.
    I am wondering if your browser is crashing because it is not finding 
its expected
configurations for the SYSTEM user.
    I was able to get around this with Excel by running the Wrapper as a 
user for which I
had already initialized Excel.  The problem for you though is that when 
running as a user
other than SYSTEM, it is not possible to set the interactive flag.  In 
my case, I was using
Excel to run a VBS script that generated a CSV file and exited.  No user 
interaction
required so it all worked.

    Not sure what browser you are using, but you might want to try 
googling around
using this as a base.

    The memory properties of the wrapper simply set the -Xms and -Xmx 
parameters to
the JVM, they have no control over the child processes.

Cheers,
Leif
