Passing Servlet ENV Variables to a PERL program 1

lotsToLearn · Oct 8, 1999

Hi, 
 
I am creating a servlet that executes some thrid party CGI scripts. I have got the servlet set up so that it executes a perl, reads the results of the program and outputs it to the client. See code snippet. 
 
BufferedOutputStream out; 
Runtime rt; 
Process p; 
BufferedInputStream in; 
String s; 
byte[] buff; 
int read; 
 
buff=new byte[4096]; 
rt=Runtime.getRuntime(); 
p=rt.exec("perl D:\\InetPub\\

http://wwwroot\\tf\\cgi-bin\\alh.cgi");

in=new BufferedInputStream(p.getInputStream()); 
out=new BufferedOutputStream(res.getOutputStream()); 
while ((read=in.read(buff, 0, 4096))!=-1) { 
if (read>0) { out.write(buff, 0, read); } 
} 
in.close(); 
out.close(); 
 
 
Where alh.cgi is. 
 
#!/usr/bin/perl 
 
print "Content-type: text/html\n\n"; 
print "<HTML><HEAD><TITLE>Missing Much Data</TITLE> 
 
<script LANGUAGE=JAVASCRIPT> 
 
 
 
</script> 
 
</HEAD>"; 
print "<BODY BGCOLOR='#FFFFFF'>"; 
print "<TITLE>Unauthorized</TITLE><H1>You are Unauthorized</H1> BLAH BLAH BLAH"; 
print "</BODY></HTML>"; 
 
 
Now incredibly, thanks to OTTO (incredible given my coding experience ) this works. However to take it to the next stage I need to pass the Environment variables to the the perl script being executed. 
 
If you know how to do this, or can offer any suggestions as to how might do this please respond. 
 
Thanks

Hi! 
 
See the "environment variables" thread. 
I posted a solution in August. 
 
Good luck. Bye, Otto. 
PS: Why do you need cgi? You could do it all with servlets (I think).
