Question

我正在尝试通过Java Web Start运行嵌入式tomcat应用程序。该应用程序在eclipse上运行良好，但是作为Web启动文件启动时会导致问题。这是我现在面临的错误。我在Maven和Tomcat 8.5.23中使用Eclipse光子

请帮帮我！

这是我的错误日志...

                                 ServletException {
String docBase = "src/main/webapp/";

Tomcat tomcat = new Tomcat();
String webPort = System.getenv("PORT");
    if(webPort == null || webPort.isEmpty()) {
        webPort = "8189";
    }
    tomcat.setPort(Integer.valueOf(webPort));

tomcat.addWebapp("/", new File(docBase).getAbsolutePath());
System.out.println("configuring app with basedir: " + new File("./" + 
docBase).getAbsolutePath());

tomcat.start();
tomcat.getServer().await();
}
}

将我的tomcat版本更改为最新的9.0.10 还将所有依赖项也更改为上述版本。这解决了问题。试试看。
