從How to set up a JDBC Connection Pool on Glassfish我想將MyQueue連接到Glassfish中的Birds JDBC資源。我收到的錯誤類似於：The name of the driver class for the datasource is missing;唯一的區別是，我使用的，而不是PostgreSQL的MySQL的：數據源的驅動程序類名稱缺失
鳥類資源：
成功的ping：
（平確實表明連接屬性是正確的？）
塊小：

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++;
}
}
豆子和facelet裏都工作正常，我只是想MyQueue連接到數據庫。我想用JPA連接到數據庫。
編輯字段的選項變灰。

Netbeans做了一些魔術，並創建了連接（我認爲）單擊企業應用程序並選擇新建 - > glassfish> jdbc連接池。
太陽resources.xml中：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE resources PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 9.0 Resource Definitions //EN" "http://www.sun.com/software/appserver/dtds/sun-resources_1_3.dtd">

</resources>
的persistence.xml：
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<exclude-unlisted-classes>false</exclude-unlisted-classes>

</persistence-unit>
</persistence>
我有點不安與sun-resources.xml並希望直接看到在GlassFish該配置。我不確定這會起作用，但是它允許netbeans從這個連接創建一個實體類，所以這看起來像是進步。雖然如此，sun-resources.xml實際上並不在glassfish中，因此這不是一個完美的解決方案。
還看到：https://netbeans.org/kb/docs/javaee/ecommerce/connect-db.html雖然似乎有點過時，但似乎與上面的教程保持一致。和http://wiki.netbeans.org/UsingJSFAndFaceletsInNetbeans – Thufir 2014-09-30 08:51:23
