Redirect input through channel and java

Question

Redirect input through channel and java

I read Creating a child process with redirected inputs and outputs on MSDN.

And I redirected the output. But input redirection is different from this example in my case.

I performed java -jar xxx.jarin a child process. And redirect the input to stdinPipe successfully. But I found that the child process, jar, is not reading the input.

I redirected the input descriptor as follows:

ZeroMemory( &siStartInfo, sizeof(STARTUPINFO) );
siStartInfo.cb = sizeof(STARTUPINFO); 
siStartInfo.hStdError = g_hChildStd_OUT_Wr;
siStartInfo.hStdOutput = g_hChildStd_OUT_Wr;
siStartInfo.hStdInput = g_hChildStd_IN_Rd;
siStartInfo.dwFlags |= STARTF_USESTDHANDLES;

// Create the child process. 

bSuccess = CreateProcess(NULL, 
    szCmdline,     // command line which I use "java -jar xxx.jar"
    NULL,          // process security attributes 
    NULL,          // primary thread security attributes 
    TRUE,          // handles are inherited 
    0,             // creation flags 
    NULL,          // use parent environment 
    NULL,          // use parent current directory 
    &siStartInfo,  // STARTUPINFO pointer 
    &piProcInfo);  // receives PROCESS_INFORMATION

When i use bSuccess = WriteFile(g_hChildStd_IN_Wr, pCmd, strlen(pCmd), &dwWritten, NULL);. It works fine on my small test jar file that is used System.out.println(), and System.in.read()for output and input.

jar, , . , , jar ConsoleReader(System.in, System.out). java. , - , ?

!

P.S. , , .

, , jline.console.ConsoleReader.readLine(">",null). java arg -nojline, !

jline.console.ConsoleReader. , - System.in.read() jline.console.ConsoleReader.readLine(">",null).

:

if (!useConsole) {
        return;
    }
    // CraftBukkit end

    jline.console.ConsoleReader bufferedreader = this.server.reader; // CraftBukkit
    String s;

    try {
        // CraftBukkit start - JLine disabling compatibility
        while (!this.server.isStopped() && this.server.isRunning()) {
            if (useJline) {
                s = bufferedreader.readLine(">", null);
            } else {
                s = bufferedreader.readLine();
            }
            if (s != null) {
                this.server.issueCommand(s, this.server);
            }
            // CraftBukkit end
        }
    } catch (IOException ioexception) {
        DedicatedServer.az().error("Exception handling console input", ioexception);
    }
