Question

从How to set up a JDBC Connection Pool on Glassfish我想将MyQueue连接到Glassfish中的Birds JDBC资源。我收到的错误类似于：The name of the driver class for the datasource is missing;唯一的区别是我使用的是MySQl而不是PostgreSql：

鸟类资源：

成功ping：

（ping确实表明连接属性是正确的？）

            </ui:define>

和bean：

package dur;

import java.io.Serializable;
import java.util.logging.Logger;
import javax.inject.Named;
import javax.ejb.Singleton;
import javax.enterprise.context.ApplicationScoped;
//import javax.inject.Singleton;

@Named
@ApplicationScoped
@Singleton
public class MyQueue implements Serializable {

    private static final long serialVersionUID = 403250971215465050L;
    private final Logger log = Logger.getLogger(MyQueue.class.getName());
    private int next = 1;

    public MyQueue() {
    }

    public int getNext() {
        log.info("next\t" + next);
        return next++;
    }
}

bean和facelet运行正常，我只想将MyQueue连接到数据库。我想使用JPA连接到数据库。

编辑字段的选项显示为灰色。

通过右键单击企业应用程序并选择新的 - ＆gt; Netbeans做了一些魔术并创建了连接（我认为） glassfish＆gt; jdbc连接池。

太阳resources.xml中：

我对sun-resources.xml感到有些不安，并希望直接在glassfish上看到这种配置。我不确定这会起作用，但它允许netbeans从这个连接创建一个实体类，所以这似乎是进步。但是，sun-resources.xml实际上并不是玻璃鱼，这使得这不是一个完美的解决方案。

Answer 1

我有一个类似的问题，它基本上是netbeans问题（这就是为什么在glassfish管理控制台中一切似乎都很好）。

解决：
1.将mysql-connector-java-5.1.23-bin.jar添加到“{$ installation_folder} \ NetBeans 8.0.1 \ ide \ modules \ ext”
2.重启netbeans
现在它应该按预期工作

此bug report也是相关的

Answer 2

要解决您遇到的同样问题，我必须在连接池中添加“driverClass”附加属性（“password”，“user”，“URL”旁边）。它的值将是“com.mysql.jdbc.Driver”。
