Manish,
My first advise to you is to Isolate the problem .
Try to write a Simple Java program which runs the unix command..and Make it
to work..
And then try integrating it in to the SErvlet.
I have been doing the same with out any problem ..although it was in
Weblogic App Server
native
Secondly,
Try Studying the servlet demostrated at :
http://www.frontiernet.net/~imaging/FileUploadServlet.html
Thirdly ,
I guess you would have to learn Java programming first before you speed ypur
way in to App Servers..:) J/king
Cheers,
Nagraj

Hye all
I am kinda new to Java Programming as such and so to
Jsp and servlet. I have a couple of questions........
[1] I get exceptions when i try to run unix command
from my servlet To be precise about the error, this is
what I get on the JSWDK1.0.1 startserver screen:
java.io.IOException: CreateProcess: rlpq
-H101.20.35.78 error=0 at
java.lang.Win32Process.create(Native Method) at
java.lang.Win32Process.<init>(Unknown Source) at
java.lang.Runtime.execInternal(Native Method) at
java.lang.Runtime.exec(Unknown Source) at
java.lang.Runtime.exec(Unknown Source) at
java.lang.Runtime.exec(Unknown Source)
I am performing the following command: rlpq
-H101.20.35.78 which will query the printer
101.20.35.78 and check the status of the printer.
However it works perfectly when I execute in a
stand-alone application and I get the above mentioned
IOException when I execute the same command from the
Servlet.
The code which I try to carry out is......
String[] tokenizedCom = new String[4]; String s;
tokenizedCom[0] = "rlpq"; tokenizedCom[1] =
"-H101.20.35.78"; try { Process myProcess =
Runtime.getRuntime().exec(tokenizedCom);
//DataInputStream in = new DataInputStream(new
//BufferedInputStream(myProcess.getInputStream())); }
catch (IOException e) { e.printStackTrace(); }
I kinda am not sure as to what the problem might be.
If possible, do send in a sample code alias to the
above code.
[2] I want to upload file from the JSP page to my
servlet. One solution I found was to use the oreilley
servlet package. I downloaded that. But I dont know
how to use it. I tried to put that in the import
statement, but not of much help. I even tried to
modify my startserver.bat file on JSWDK1.0.1 by
setting the class path.
Please advice on it.
Thanks a lot
Manish
