How to open IE from a java program

Hey I tried to open IE from a java program. the command start iexplorer works on command prompt and terminal but when used in a java program throws a IOException. When I execute the command cmd start iexplorer the program is just running without stopping for almost 15 minutes

 String command = "cmd start iexplore";
        try {
            Process p = Runtime.getRuntime().exec(command);
            p.waitFor();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

This is the call stack of from VScode: image

can someone help me with this please

Solution

  • All you are doing is running "cmd" in background. If iexplore is on your system Path then this may work:

    String[] cmd = new String[] {"cmd", "/c", "start iexplore"};

    The "/c" option tells CMD.EXE to start the process, and then CMD exits immediately [in your case it is hanging around for more input]. Also you need to read the STDERR stream of the process to see any error messages from CMD.
