Hi, Iam trying to code in java and wanted to run the commands in the Unix remote servers. I have the following code to run multiple GREP commands from a file in a single session. But when i execute this, the first command executes successfully, whereas from the next line it says "Exception Occured java.io.IOException: A remote execution has already started." Following is my code snippet : FileReader fr = new FileReader("grepcommands.txt"); BufferedReader br = new BufferedReader(fr); String inputscript=""; sess= conn.openSession(); while((inputscript=br.readLine())!=null){ sess.execCommand(inputscript); } sess.close(); It would be great if anyone can provide me the solution for this.
