Websphere App server[警告]CWWKC0044W和[警告]CWWKC0022W:

Question

运行Websphere App server V8.5 Liberty配置文件。我找不到任何可以解决这些警告的帮助。我在Eclipse上。

        **************   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]CWWKC0022W:[com.ibm.ws.anno.info.internal.ClassInfoCache@957735840]对类[java.lang.Object]的扫描导致异常。消息是:[Class[java.lang.object]from resource[java/lang/object.Class]Exception creating reader]broading[null]。

这些警告看起来非常像您试图在Java8下运行Liberty Profile。

Liberty profile（还）不支持Java8，所以据我所知，您目前唯一支持的选项是回到Java7。
