尝试使用JDBC连接到DB2时出现DisconnectNonTransientConnectionException

Question

在尝试使用Java JDBC连接到DB2时获取异常。

当我使用Scala连接到相同的数据库时，它正在运行，但是使用JAva JDBC时我无法连接，请帮助我解决此错误，我已经可以访问防火墙了。

package com.java.tutorial;

import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class DBConnection {

public static void main(String args[]) {
    Connection conn = null;
    Statement stmt = null;
    ResultSet result = null;
    try {
        Driver myDriver = new com.ibm.db2.jcc.DB2Driver();
        DriverManager.registerDriver(myDriver);

        String URL = "jdbc:db2://mopvsm1.mop.com:38362/RDBND10A";
        String USER = "BIMDLM";
        String PASS = "GOOD424";
        String sql = "select * from MODELING_VERSION";

        conn = DriverManager.getConnection(URL, USER, PASS);
        stmt = conn.createStatement();
        result = stmt.executeQuery(sql);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } finally {
        try {
            if (conn != null && result != null && stmt != null) {
                conn.close();
                result.close();
                stmt.close();
            }
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
}

我应该能够使用此代码连接到数据库。但是出现以下异常：
