public class restart_tomcat {
public static void main(String[] args) throws SDKException, IOException {
Runtime rt = Runtime.getRuntime();
try {
// Process process1 = Runtime.getRuntime().exec("cmd /c start cmd.exe /K " + cmd1);
rt.exec("cmd /c start cmd.exe /K \"cd C:\\Program Files (x86)\\SAP BusinessObjects\\tomcat\\bin&&startup.bat\"");
System.out.println("successful");

I need to restart my Tomcat server from Java code. I'm a beginner in Java. I try to do that by cmd. I need to stop tomcat then restart it. I try this code. It works with just two commands (one &&) and it doesn't work if I add a third command (two && in the line exec("cmd /c start cmd.exe ...)).
PS: If another way exists to restart Tomcat with Java code please tell me
public class restart_tomcat {
public static void main(String[] args) throws SDKException, IOException {
Runtime rt = Runtime.getRuntime();
try {
// Process process1 = Runtime.getRuntime().exec("cmd /c start cmd.exe /K " + cmd1);
rt.exec("cmd /c start cmd.exe /K \"cd C:\\\\Program Files (x86)\\\\SAP BusinessObjects\\\\tomcat\\\\bin&&startup.bat\"");
System.out.println("succesful");
} catch (IOException e) {
e.printStackTrace();
}
}
}

这可能是好的了解为什么需要从Java代码启动/停止Tomcat，这是一项作业还是其他什么事情吗？在现实世界中，我们有初始化脚本，可以通过在终端中运行它们来启动/停止它。您可以使用一个非常简单的Shell脚本（yourscript.sh）来自动化这个过程，并添加以下内容：
#!/bin/bash
<path_to_tomcat>/bin/shutdown.sh
<path_to_tomcat>/bin/startup.sh
如果您真的需要从Java代码中执行此操作，您可能会在以下资源中找到答案：

It would be good to know why do you need to start/stop Tomcat from java code, is that a homework or something else? In the real-world, we have initialization scripts that can start/stop it by simply running them from the terminal. You can automate that with a very simple shell script (yourscript.sh) and add the following content:
#!/bin/bash
<path_to_tomcat>/bin/shutdown.sh
<path_to_tomcat>/bin/startup.sh
If you really need to do it from Java code, you may find your answer in one of these resources:
