How to configure "Start/Stop a service" in install4j? - install4j

Question

I have created an application with install4j and after successful installation, I need to restart few services in Linux/Windows machine.
I have written a following script to stop and start the services in java. But I want to handle this operation within install4j.
int restartService = Util.showOptionDialog("\nClick on \"Yes\" to restart the service now and Click on \"No\" to restart the service manually later.",new String[]{"Yes","No"},1);
//0= yes restart
//1= no
if(restartService == 0){
if(Util.isWindows())
{
context.getProgressInterface().setStatusMessage("Checking service is present or not...");
context.getProgressInterface().setPercentCompleted(10);
String serviceName = "vspherewebclientsvc";
try {
boolean isProcessActive = false;
Util.logInfo(null,"Step 1 : Checking service is present or not...");
Process p = Runtime.getRuntime().exec("sc query " + serviceName);
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = reader.readLine();
while (line != null) {
if (line.trim().startsWith("STATE")) {
while (!("4".equals(line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim()) || "2".equals(line.trim().substring(line.trim().indexOf(":") + 1, line.trim().indexOf(":") + 4).trim()))) {
Util.logInfo(null,"running");
}
Util.logInfo(null,"\t-> Service is Active!");
isProcessActive = true;
}
line = reader.readLine();
}
if (isProcessActive) {
context.getProgressInterface().setStatusMessage("Stopping service...");
context.getProgressInterface().setPercentCompleted(20);
Util.logInfo(null,"Step 2 : Stopping service...");
String[] stop = {"cmd.exe", "/c", "net", "stop", serviceName, "/yes"};
Process p1 = Runtime.getRuntime().exec(stop);
p1.waitFor();
BufferedReader reader1 = new BufferedReader(new InputStreamReader(p1.getInputStream()));
String line1 = reader1.readLine();
while (line1 != null) {
line1 = reader1.readLine();
}
context.getProgressInterface().setStatusMessage("Waiting for Stop service...");
context.getProgressInterface().setPercentCompleted(40);

How can we achieve this with "Start/Stop a service" in install4j?

Answer 1

There are "Stop a service" and "Start a service" actions in install4j that you can use for this purpose.
