Question

运行Websphere App Server V8.5 Liberty Profile。我没有找到任何可以解决这些警告的帮助。我正在吃日食。

        **************   Here's my servlet code ************
        package com.rocketsoft.zoskmip.kmipuser;

        import java.io.IOException;
        import java.io.PrintWriter;
        import javax.servlet.ServletException;
        import javax.servlet.annotation.WebServlet;
        import javax.servlet.http.HttpServlet;
        import javax.servlet.http.HttpServletRequest;
        import javax.servlet.http.HttpServletResponse;
         /**
         * Servlet implementation class AddUser
         */
        @WebServlet("/user")
        public class AddUser extends HttpServlet {
     private static final long serialVersionUID = 1L;

         public AddUser() {
    super();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
       throws ServletException, IOException {
    PrintWriter printWriter = response.getWriter();
    printWriter.print("Welcome");
    String firstName = request.getParameter("fname");
    printWriter.print(firstName);
}
}

********警告*************

[警告] CWWKC0044W：扫描类和注释数据时发生异常。例外是{0}。

[警告] CWWKC0022W：[com.ibm.ws.anno.info.internal.ClassInfoCache@957735840]类[java.lang.Object]的扫描导致异常。消息是：[class [java.lang.Object] from resource [java / lang / Object.class] Exception creation reader]由[null]引起。

警告看起来非常像您尝试在Java8下运行Liberty Profile。

Liberty profile does not (yet) support Java8，据我所知，您目前唯一支持的选项是返回Java7。
