Writing a bash script from java

Question

I have a java program that writes a bash script. Unfortunately when this script is saved, I need to modify it (ubuntu 10.04) to enable running it as an executable. Any way of circumventing this?

I understand that it is a security thing...

If you are not using JDK 1.6 you can do following:

After writting file you can do something like

Runtime.getRuntime().exec("chmod +x "+yourfile.sh);
