Question

i am writing my first struts example .i followed the exact steps but even then facing this problem,dont know whats wrong code was working on my teacher's machine but on mine not ,i think there is a small mistake i am doing plz help me to locate 1) i have index.jsp

<%@ taglib uri="/struts-tags" prefix="s" %>
<s:form action="login">
<s:textfield name="username" label="username:"></s:textfield>
<s:submit></s:submit>
</s:form>

2) the bean package with Loginaction class(pogo class)

package bean;

public class Loginaction {
    String username;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
    public String execute()
    {


            return "success";


    }



}

3) the struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
   "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
   "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="demo" extends="struts-default">
<action name="login" class="bean.Loginaction">
<result name="success">welcome.jsp</result>

</action>
</package>

</struts>

4) the welcome.jsp

<h1>hi user.</h1>

5) the web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app id="WebApp_9" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>struts1</display-name>
  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

6) and the directory structure

both package and the struts.xml in the src folder and else in the web-inf (jsps and the web.xml)

on the console i am getting``

Was it helpful?

Solution

This means that a process is already using port 8080. Commonly, newbies are tripped up by starting a tomcat instance without having shutdown the previous one. You should check that. Also, it's possible that there was already another service listening on port 8080. If so, you need to identify what process is using port 8080.

My advice is that you learn what tools are available on your system that will help you answer the following questions:

1) what processes are running?

2) Which ones have network ports open for listening to incoming requests, aka which ones are servers?

Once you can do this, you'll know how to identify the conflicting process and then you just need to go shut it down.

OTHER TIPS

Try killing all the tomcat and Java processes on the machine you saw the error and try starting tomcat again. In your case 8080 is already being used by another process. Kill that first and try again.

Just change the tomcat server http port nb in the server.xml file remaining keep as it is.

to do that follow the below steps:

  1. open ../tomcat5.x/conf/server.xml and change the port nb such like 8081 or 8090 any instead of 8080
    In...
    <---Define a non-SSL HTTP/1.1 Connector on port 8080---->
    <Connector port="8090" ..........>
  2. Save it.
  3. finally start the tomcat server

thats all.
thank you.
