Google App Engine 上的 Quercus：类未加载
致命错误：没有匹配的类连接
index.php
<?php
import database.connection;
$connection = connection::get()->getPersistenceManager(); // ***ERROR HERE***
?>
connection.java
package database;
import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManagerFactory;
public final class connection {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("transactions-optional");
private connection() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
Quercus 在其他方面配置良好，PHP 实现在 GAE 上运行顺利。但是当我尝试初始化类时，PHP 找不到它们。我做错了什么？
Fatal Error: no matching class connection
index.php
<?php
import database.connection;
$connection = connection::get()->getPersistenceManager(); // ***ERROR HERE***
?>
connection.java
package database;
import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManagerFactory;
public final class connection {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("transactions-optional");
private connection() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
Quercus is otherwise configured fine, PHP implementation works smoothly on GAE. But when I try to initialize classes, PHP can't find them. What am I doing wrong?

我是因为你发布这个问题才发现Quercus的存在！
我的猜测是 Quercus 无法实例化该对象，因为“连接”类有一个私有构造函数。
查看文档，类似 java_class("database.connection") 之类的东西可用于访问无法实例化的类中的静态方法。
I only discovered that Quercus existed due to you posting this question!
My guess would be that Quercus cannot instantiate the object because the class "connection" has a private constructor.
Looking at the documentation, something like java_class("database.connection") can be used to access static methods in classes which cannot be instantiated.
