I have a jsp page, there I want to execute the following shell script with the exit codes for 0 and 1 for success and fail respectively thru Runtime.getRuntime().exec().



The exection is success while execting the shell script alone and also thru a stand alone Java program. But While calling this shell script from the JSP, I am always getting the negative response, that is the Process.exitValue() returns always 1.

Any suggestions and help appreciated !!!

if [ -f "help.txt" ]



That would appear to depend on the "current" directory. You have no control over the current directory in the servlet environment.

Hi,

Thats how I have done.I am running an exe file to convert dms to tiff.I have used absolute path.

String[] cmd = { "C:\\imaging\\kman_DMStoTiff\\bin\\kman_DMStoTiff.exe", "C:\\imaging\\test.dms", "C:\\jboss-4.0.5.GA\\server\\default\\deploy\\documents.war\\pal1.tiff" } ;
Process p = Runtime.getRuntime().exec(cmd) ;
BufferedReader in =new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
