How to launch a java application from Microsoft SQL Server

Question

Hi everyone
I noticed the following line in a trigger will launch an executable.
EXEC master..xp_cmdshell '"C:\Program Files\SkillSets.exe"', NO_OUTPUT
Does anyone know if this same statement will launch a java program? Or does anyone have any positive experience with that ?

Answer 1

yes...
check this basic example:
public class GoodWindowsExec{
public static void main(String args[]){
if (args.length < 1){
System.out.println("USAGE: java GoodWindowsExec <cmd>");
System.exit(1);
try{           
String osName = System.getProperty("os.name" );
String[] cmd = new String[3];
if( osName.equals( "Windows NT" ) ){
cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
}else if( osName.equals( "Windows 95" ) ){
cmd[0] = "command.com" ;
cmd[1] = "/C" ;
cmd[2] = args[0];
Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec(cmd);
// any error message?
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");
// any output?
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT");
// kick them off
errorGobbler.start();
outputGobbler.start();
// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
t.printStackTrace();
