JTOpen 程序调用套接字超时

JTOpen ProgramCall Socket Timeout

我正在开发一个 Web 应用程序(运行 on Tomcat),它使用 JTOpen ProgramCall class( com.ibm.as400.access.ProgramCall).我的问题是程序调用需要超过 30 秒才能响应,这会触发 java.net.SocketTimeoutException: Read timed out exception.

有一个 setTimeout() 方法可用于此 class,但它似乎对套接字超时没有影响。我还检查了我的 Tomcat 配置,没有发现任何会导致此行为的内容。

有谁知道改变这种实现的超时的方法吗?

代码:

pgmCall.setProgram(getCompleteName(), parmList);
initializeAS400TextParameters();

// Run the AS/400 program.
try {
    Trace.setTraceDiagnosticOn(true);
    Trace.setTraceInformationOn(true);
    Trace.setTraceWarningOn(true);
    Trace.setTraceErrorOn(true);
    Trace.setTraceDatastreamOn(true);

    if (pgmCall.run() != true) {
        messageList = pgmCall.getMessageList();
        for (int i = 0; i < messageList.length; i++) {
            log.debug("Error Message " + i + "  " + messageList[i]);
        }
        setCompletionMsg("Program call failed.");
        log.debug("442 Program call failed.");

        return false;
    } else {
        messageList = pgmCall.getMessageList();
        for (int i = 0; i < messageList.length; i++) {
            log.debug("Success Message " + i + "  " + messageList[i]);
        }
        setCompletionMsg("Program called ok.");
        log.debug("452 Program called ok.");

        return true;
    }
} catch (Exception e) {
    // This is where the timeout exception is thrown
    log.debug("Error Running Program: " + e.getMessage() + "  " + e.getLocalizedMessage());
    setCompletionMsg(e.getMessage());
}

嗯,又过了几个小时,我找到了解决方案。显然,最初的开发人员向 JDBC 连接字符串添加了一个 socket timeout 参数 - 只需删除该参数就可以解决问题,因为默认值为 0 或无限超时。

之前:

String connectionStr = "jdbc:as400://" + systemInfo.getIPAddress() + ":1527" + ";naming=system;socket timeout=30000;thread used=false;errors=full;prompt=false;date format=iso;block size=128;transaction isolation=none;user=" + systemInfo.getUserName() + ";password=" + systemInfo.getPassword();

之后:

String connectionStr = "jdbc:as400://" + systemInfo.getIPAddress() + ":1527" + ";naming=system;thread used=false;errors=full;prompt=false;date format=iso;block size=128;transaction isolation=none;user=" + systemInfo.getUserName() + ";password=" + systemInfo.getPassword();
