我创建了一个 EJB 包，其中 Glassfish V 4.0 和 postgre sql 分别作为服务器和数据库。Glassfish 和 postgre 是远程安装的。

我创建了一个连接池和 JNDI

让我知道是否需要更多详细信息

当我运行我的类文件时，它给了我以下错误

我的类文件有 main 方法

public static void main(String args[])
{
    dummy p = new dummy();
    PreparedStatement stmt = null;
    String sql="";
    try(Connection connection = DBConnection.getConnection();)
    {
        sql = "INSERT INTO databasename.request (requestId)" +
            "VALUES (?)";
        stmt = connection.prepareStatement(sql);
        stmt.setString(1, "1324");
        stmt.executeQuery();
    }
    catch(Exception ex){

    }
}

DBConnection 类文件包含以下详细信息

public class DBConnection {
    private static DataSource ds;
    static {
        try {
            InitialContext ctx = new InitialContext();
            ds = (DataSource) ctx.lookup("jdbc/databasename");
        } catch (NamingException ex) {
            Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE,null,ex);
        }
    }


    public static Connection getConnection() {
        Connection connection = null;
        try {
            connection = ds.getConnection();

        } catch (SQLException ex) {
            Logger.getLogger(DBConnection.class.getName()).log(Level.SEVERE, null, ex);
        }
        return connection;
    }
}

提前致谢

我通过添加glassfish-embedded-all到我的解决了这个问题pom.xml：

<dependency>
    <groupId>org.glassfish.main.extras</groupId>
    <artifactId>glassfish-embedded-all</artifactId>
    <version>3.1.2.2</version>
</dependency>
