Question

我是servlet jsp的初学者我的pom.xml就像我在apache tomcat 7.0.57中运行它时得到的错误

错误我得到了类型异常报告

message无法为JSP编译类：

说明服务器遇到内部错误，导致无法完成此请求。

例外 org.apache.jasper.JasperException：无法为JSP编译类：

An error occurred at line: [32] in the generated java file: [C:\apache-tomcat-7.0.57\work\Catalina\localhost\deltaWebServices\org\apache\jsp\index_jsp.java]
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

POM.xml看起来像这样

我的index.jsp是

<%@ page language="java" contentType="text/html; charset=windows-1256"
pageEncoding="windows-1256"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">`<%@ page import="come.here.webservices.*"%>`<html><body>`<form action="deltaWebServices/come.here.webservices.ConfigServlet">

            <td>Please Enter Workspace</td>
            <td><input type="text" name="Workspace" /></td>

        </tr>
        <tr>
            <td>Please Enter region</td>
            <td><input type="text" name="region" /></td>

        </tr>
        <tr>
            <td>Please Enter Rule</td>
            <td><input type="text" name="rule" /></td>

        </tr>

        <tr>

            <td><input type="submit" value="submit" /></td>

        </tr>

    </table>
</form>`</body></html>`

我的配置servlet是

package come.here.webservices;

 import java.io.IOException;
 import javax.servlet.ServletConfig;
 import javax.servlet.ServletException;
 import javax.servlet.http.HttpServlet;
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;

 import org.hsqldb.server.Servlet;

 /**
 * Servlet implementation class ConfigServlet
 */
public class ConfigServlet extends HttpServlet {
private static final long serialVersionUID = 1L;

 /**
 * @see HttpServlet#HttpServlet()
 */
public ConfigServlet() {
    super();
    // TODO Auto-generated constructor stub
}

/**
 * @see Servlet#init(ServletConfig)
 */
public void init(ServletConfig config) {
    // TODO Auto-generated method stub
}

/**
 * @see Servlet#destroy()
 */
public void destroy() {
    // TODO Auto-generated method stub
}

/**
 * @see Servlet#getServletConfig()
 */
public ServletConfig getServletConfig() {
    // TODO Auto-generated method stub
    return null;
}

/**
 * @see Servlet#getServletInfo()
 */
public String getServletInfo() {
    // TODO Auto-generated method stub
    return null;
}

/**
 * @see HttpServlet#service(HttpServletRequest request, HttpServletResponse
 *      response)
 */
protected void service(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
}

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
 *      response)
 */
public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    // TODO Auto-generated method stub
    ConfigBean config = new ConfigBean();
    config.setWorkspace(request.getParameter("Workspace"));
    config.setRegion(request.getParameter("region"));
    config.setRule(request.getParameter("rule"));
}

/**
 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
 *      response)
 */
public void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    // TODO Auto-generated method stub
    ConfigBean config = new ConfigBean();
    config.setWorkspace(request.getParameter("Workspace"));
    response.sendRedirect("Added.jsp");
}

}

web.xml是

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
<display-name>Archetype Created Web Application</display-name>

    <servlet-name>ConfigServlet</servlet-name>
    <url-pattern>/deltaWebServices/come.here.webservices.ConfigServlet</url-pattern>
</servlet-mapping>
</web-app>

错误是：

org.apache.jasper.JasperException: Unable to compile class for JSP:

在JSP中，我在页面底部发现了一些代码工件为'（单引号）：

</form>`</body></html>`

尝试清除并检查它。
