TomEE - 无法为Web模块创建注释扫描程序：null

时间：2014-04-07 20:00:06

标签： java java-ee tomcat gwt

我很抱歉问题标题的模糊性，但我不完全确定我问的问题是什么。我正在尝试部署我在TomEE上使用GWT构建的示例应用程序，但由于某种原因部署失败。我有一个堆栈跟踪，但那个文本墙对我来说完全没有意义。我知道注释扫描仪是什么，但我不知道为什么tomee无法创建一个或如何与我必须做的任何事情相关联来解决它。该应用程序基本上是来自here的StockWatcher。我除了把gwt输出放在我的战争的根目录上之外什么也没做，然后像这样添加一个web.xml（我不是那个有实际客户端服务器通信的部分所以我只添加默认的servlet到提供静态内容）（在linux下运行，使用oracle jdk 1.7）

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     version="2.5">

    </servlet>

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

这是catalina.out的最后一项输出

再一次，抱歉这不是一个更具体的问题，但我实际上并不了解这一点，实际上可以说出错误的原因。

1 个答案:

答案 0 :(得分：5)

Caused by: java.lang.IllegalArgumentException

您是否尝试使用Java 8编译的类？ AFAICT，ASM4仅支持Java 7字节码（或旧版本），并且您需要ASM5 for Java 8.

尝试重新编译面向Java 7的类。
