java - 以编程方式执行服务器 Jar (Caucho Resin)

Question

我已经成功使用了 Caucho Resin Web 服务器，并且正在考虑将其打包到 java 应用程序中。他们提供了一个 jar 文件和代码，以便以编程方式启动服务器。

Example: example/TestResin.java

package example;

import com.caucho.resin.*;

public class TestResin {

  public static void main(String []args)
  {
    ResinEmbed resin = new ResinEmbed();

    HttpEmbed http = new HttpEmbed(8080);
    resin.addPort(http);

    WebAppEmbed webApp = new WebAppEmbed("/", "/var/www/htdocs");
    resin.addWebApp(webApp);

    resin.start();
    resin.join();
  }
}

但是我收到以下错误

解决方案:

添加了在 glassfish 安装目录中找到的 javaee-16.jar 库和所有作品。显然从 Oracle 下载 glassfish-api.jar 不起作用，因为只包含方法声明而没有实现。

Answer 1

使用它来解释 jar，就像使用 java -jar ... 运行它一样:

File f = new File("resin-3.1.0/lib/resin.jar");
URL url = new URL("file", null, f.getAbsolutePath());
ClassLoader cl = new URLClassLoader(new URL[] {url});
Class<?> mcls = cl.loadClass("a.b.c.Main");
Method mmethod = mcls.getMethod("main", new Class[] {String[].class});
mmethod.invoke(mcls);

在这里，Resin 将在它自己的类加载器中运行。
