Java JDBC executeUpdate arraycopy：长度-1434为负值。

Question

我在DB2中调用存储过程时遇到了问题。如果我不使用java运行它，它就能正常工作。谁能帮我解决这个问题？这个问题不取决于消息变量，我不知道它有什么问题。

下面是代码。

CallableStatement cstmt = con.prepareCall("call tb.proc(?,?,?,?, ?)");
        cstmt.setString(1, message);
        cstmt.registerOutParameter(2, Types.VARCHAR);
        cstmt.registerOutParameter(3, Types.VARCHAR);
        cstmt.registerOutParameter(4, Types.INTEGER);
        cstmt.registerOutParameter(5, Types.CHAR);
        cstmt.executeUpdate();

SP定义，按照要求，这个调用其他存储过程。

CREATE PROCEDURE tb.proc (IN MESSAGE VARCHAR(300), OUT RESPONSE VARCHAR(300), OUT RESPMESSAGE VARCHAR(300), OUT E INTEGER,  OUT ESTATE CHAR(5))

BEGIN

    DECLARE varCode VARCHAR(300);
    DECLARE varUPD_SID VARCHAR(300);
    DECLARE varP_ZAPR VARCHAR(300);
    DECLARE varDATE_PLREM VARCHAR(300);
    DECLARE varDATE_PLSP VARCHAR(300);
    DECLARE varP_XAR VARCHAR(300);
    DECLARE varUPD_TIME VARCHAR(300);
    DECLARE varUPD_USER VARCHAR(300);
    DECLARE varOperation VARCHAR(300);
    DECLARE varNINV VARCHAR(300);
    DECLARE SQLCODE INTEGER;
    DECLARE SQLSTATE CHAR(5);

    DECLARE ErrorCode CHAR(5) DEFAULT NULL;
    DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING
        BEGIN
        SET E = SQLCODE, ESTATE = SQLSTATE;
        END;

    CALL TB.SPLITMESSAGE(MESSAGE, varCode, varUPD_SID, varNinv, varOperation, varP_Zapr, varDate_Plrem, varDate_Plsp,  varP_Xar);
    CALL TB.VALIDATEFORMAT(varCode, varUPD_SID, varNinv, varOperation, varP_Zapr, varDate_Plrem, varDate_Plsp,  varP_Xar, ErrorCode);
    IF ErrorCode IS NULL
        THEN
            CALL TB.VALIDATEFIELDS(varCode, varUPD_SID, varNinv, varOperation, varP_Zapr, varDate_Plrem, varDate_Plsp,  varP_Xar, ErrorCode);
    END IF;

    CALL TB.PROC2(Message, varCode, varUPD_SID, varNinv, varOperation, varP_Zapr, varDate_Plrem, varDate_Plsp,  varP_Xar, ErrorCode,
                            RESPONSE, RESPMESSAGE);

END 

这就是错误的地方

这看起来是一个 已知问题 - 你需要升级到最新的DB2 JDBC驱动程序。
