Executing a sh file from java program in foreground

[Mukti chandnani]

Hi

My purpose is to restart my Java application from within the application.
For this I have created a Java program that runs a sh file. This sh file has the command to start the same java Program.
when i run the parent Java program it executes the sh file and runs the Java Program in it in background. I want this program to run in foreground since the program takes inputs from the user. How can i make the program run in foreground.

Following is the code i use to execute the sh file

  

String LINUX_CLIENT_BATCH_FILE = "client.sh";
String command = "./" + LINUX_CLIENT_BATCH_FILE;
Process theProcess=Runtime.getRuntime().exec(command);
System.exit(0);

Following is sh file

   

#!/bin/bash -e

rm -rf sdt-socket-client.log*
cp=".:conf:"

for lib in `find -name \*.jar`
do
	cp="$cp:$lib"
done
if [ $1 ]; then
java -XX:NewSize=128M -XX:MaxNewSize=128M -XX:SurvivorRatio=8 -Xms350M -Xmx350M -Xrs -cp $cp com.sdt.A.D 'conf/' "localhost" 4445 'db/' $1 $2 $3 & echo $! > /usr/local/srb/srb_java.pid
else 
java -XX:NewSize=128M -XX:MaxNewSize=128M -XX:SurvivorRatio=8 -Xms350M -Xmx350M -Xrs -cp $cp com.sdt.A.D 'conf/' "localhost" 4445 'db/'
fi

Thanks

What do you mean here by foreground and background? Can you please be a bit more elaborate?

If I understand you correctly you should able to use the command "fg" to bring your background job to the foreground. However, I don't know how to put this running foreground job back to background because you are inside the java program. If you Ctrl+C you then exit the java program killing the job. At least that's what I got on my linux box.
