joey...

no matter what command i use between <<EOF and EOF, all the commands are terminated after a while with the same exception that is coming from java class which util.sh is using.

The thing is that when i run the same commands (that are in <<EOF and EOF) seperately...the commands are not terminated until they are finished. Further the console waits for "exit" command to exit the console.

If you still asking questions...then we are wasting time to understand the behaviour of util.sh.

It is the shell which is disconnecting after supplying the commands to util.sh (that are in between <<EOF and EOF).

What I am looking for is a way to run the commands inside <<EOF and EOF while waiting till the commands are finished. I wonder whether it is possible if we use <<EOF...EOF ?????

first off - the problem is probably in util.sh.

Since we are "black-boxing" util.sh it makes it really hard. I think you are getting a SIGHUP sent to a child process in util.sh, so let's try a nohup...
This script assumes util.sh uses read to get commands

Code:

# script1
echo "
connect
dump 
" | util.sh

Code:

nohup script1 &
wait

It would be far easier to nohup whatever is going on inside util.sh.... this is just a (probably) bad guess.

jim thanks for the suggestion.

I tried it and still no luck.

Probably I need to follow up with the vendor.
