如何用不同于tomcat的用户在tomcat中运行我的Web应用程序？

Question

What Ian wanted to do is run some external program or command from my WEB application (.sh, .pl even use directly ProcessBuilder or Runtime)

I achived to run the program or commands in my server, but the problem is that all of then are running as tomcat user. Then, for instance when I try to use ssh with public key I need to do a sudo -u "user" and then run the program or command. But unfortunatelly, I dont know why, it deesn't work.

After three days of troubleshooting, prof&error and google it, I'm thinking to run my application or procces wit a diferent user, thus avoid to use sudo command.

Then, I would like to know if somebody could tell me how I can do it or if there is any other best way to do that.

Answer 1

Finally what I've done is to exacute my ssh throught JSch and public key authentication. On this way I dont need to use sudo command since I can point out my user and private key. Oviously it's not run tomcat with different user but it fix my problem.
