Run .sh file using java

[Manpreet Patil]

Hi guys,

i want to reload apache trrough my java application on opensuse server.My .sh file placed on the path "/usr/share/tomcat6/ ". I am using following code but the output printed on tomcat log is " null "

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("sh apacheReload.sh");
process.waitFor();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
System.out.println("><><>apache restart<><><>"+br.readLine());

where apacheReload.sh is my bash file that contains:-
#! /bin/bash
/etc/init.d/apache2 reload

But when i try to reload the apache through" sh apacheReload.sh" on console it works fine.

Regards,
Manpreet

Start by reading this article.
Also, you should use absolute paths to all involved files instead of relative paths like "sh" and "apacheReload.sh".

i tried with the absolute path like this

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("sh /usr/share/tomcat6/apacheReload.sh");
process.waitFor();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
System.out.println("><><>apache restart<><><>"+br.readLine());



but still i am facing same problem.........

hi,

have you tried the way of tomcat restarting as it tomcat-manager does ? tomcat ships with ant task that does redeployment well. and invoking ant task from java code looks better than running sh manually. plus it will gives you crossplatfom-compatibility.
