I have a class (stored in server/java) that returns a Response type object and I want to use it in adapters. public class CorsResponse { public static Response build() { return Response .ok() .header("Access-Control-Allow-Origin", "*") .header("Access-Control-Allow-Methods", "GET, POST") .header("Access-Control-Allow-Headers", "accept, origin,
我有一个类（存储在服务器/ Java），返回一个Response类型的对象，我想在适配器中使用它。 public class CorsResponse { public static Response build() { return Response .ok() .header("Access-Control-Allow-Origin", "*") .header("Access-Control-Allow-Methods", "GET, POST") .header("Access-Control-Allow-Headers", "accept, origin, content-type")
Is there any way to create a URL from a byte array? I have a custom class loader which stores all the entries from a JarInputStream in a HashMap storing the entry names with their bytes. The reason I'm looking to create a URL from a byte array is to satisfy the getResource(String name) method found in ClassLoaders. I've already accomplished getResourceAsStream(String name) by using a B
有什么办法从字节数组创建一个URL？ 我有一个自定义的类加载器，它将所有来自JarInputStream的条目存储在一个HashMap中，这些HashMap存储了条目名和字节。 我期望从字节数组创建URL的原因是为了满足ClassLoaders中的getResource（String name）方法。 我已经通过使用ByteArrayInputStream完成了getResourceAsStream（String name）。 假设您使用自定义类加载器，并且希望将内容的字节存储/缓存在散列映射中（而不是byte []
Possible Duplicate: Difference betweeen Loading a class using ClassLoader and Class.forName AFAIK, two ways are provided in java to init a class from its name.

In my code, I have a nestted class that holds an object and an integer. This is to mark the beginning and end locations for a sublist method. The code executes to the point that the object and integer have established values. I've verified this in the debugger. The next line then calls ListLoc<E> startNode= new ListLoc<E>(start, startElement); and that is what trips the exc
在我的代码中，我有一个嵌套类，它包含一个对象和一个整数。 这是为了标记子列表方法的开始和结束位置。 代码执行到对象和整数已经建立值的点。 我已经在调试器中验证了这一点。 下一行然后调用ListLoc<E> startNode= new ListLoc<E>(start, startElement); 这就是例外情况。 该类已被定义为 private class ListLoc<E>{ public Chunk<E> node; public int index; /* This object
I am trying to create a custom class loader to accomplish the following: I have a class in package com.company.MyClass When the class loader is asked to load anything in the following format: com.company.[additionalPart].MyClass I'd like the class loader to load com.company.MyClass effectively ignoring the [additionalPart] of the package name. Here is the code I have: public class
我正在尝试创建一个自定义类加载器来完成以下操作： 我在包com.company.MyClass有一个类 当类加载器被要求以以下格式加载任何东西时： com.company.[additionalPart].MyClass 我想让类加载器有效地加载com.company.MyClass忽略包名的[additionalPart]。 这里是我有的代码： public class MyClassLoader extends ClassLoader { private String packageName = "com.company."; final private String myClass
I need to get names of all java packages loaded by the JVM. This is to display a package browser like the ones found in IDEs. I can get the package list of the current classloader and its ancestors by accessing protected "packages" field of the ClassLoader class. But i'm unable to get the packages loaded by other webapps as they have their own class loaders. I'm testing this
我需要获取由JVM加载的所有Java包的名称。 这是为了显示一个像在IDE中发现的软件包浏览器。 通过访问ClassLoader类的受保护“包”字段，我可以获取当前类加载器及其祖先的包列表。 但我无法获得由其他webapps加载的包，因为他们有他们自己的类加载器。 我在Weblogic服务器上测试这个 Weblogic安全模型的预期行为是您无法访问其他Web应用程序的类加载器。 这不是你能够解决的问题 - 请参阅这篇文章以获取更多信息。 您需要
I'm trying to practice myself with custom class loaders, and I've some questions. Is there a way to indicate the JVM to use my custom class loader globally? For example, I wrote small app running under Tomcat 6. The servlet is managed by the container, where should I set my class loader? In addition, the webapp uses some 3rd party jars, can I control the classes loading of those jars?
我试图用自定义类加载器来练习自己，我也有一些问题。 有没有一种方法可以指示JVM全局使用我的自定义类加载器？ 例如，我写了一个在Tomcat 6下运行的小应用程序。该servlet由容器管理，我应该在哪里设置类加载器？ 另外，webapp使用一些第三方jar，我可以控制这些jar的类加载吗？ 对于独立应用程序，上述答案会有所不同吗？ 谢谢！ 您可以将系统默认类加载器设置为JVM参数： java -Djava.system.class.loader =com.
