I have produced a perl script to do some printing and database

The script connects to a postgresql database, selects a parent-
record via an argument and then prints some information from the
children records.
When I run this script from a shell, it runs fine.
However, when I call the script from the webobjects application, I
get an error message:
...
The java code that calls the script is:
****************************************
commands[0] = "/usr/bin/perl";
commands[1] = "/usr/local/bin/printorder.pl";
commands[2] = " --ordernr";
commands[3] = order.orderid().toString();
vars[0] = "PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/
bin";
vars[1] = "LD_LIBRARY_PATH=$LD_LIBRARY_PATH";

Is there anybody that has experienced something similar and has
come up with a solution?
You are setting the perl script's environment variables in a way that
doesn't work.
If you run the perl script from a shell, the interpreter inherits a
suitable environment.
If run from java.lang.Runtime, LD_LIBRARY_PATH will be set to
'$LD_LIBRARY_PATH'. The dollar expansion is something done for you
by the shell; but there is no shell, so no substitution is done.
Rewrite your code to initialize vars[0] and vars[1] using explicit
values, perhaps obtained via java.lang.System.getenv().
