why getting 404 error? page is there.

[ankur rathi]

Hi,

I am really confuse and stuck with this problem.

I have placed a project SessionTest into webapps directory of tomcat like this way:

         tomcat 
           |
        webapps
           |
       SessionTest
        |       |
   index.jsp   WEB-INF
                |   |
           web.xml  classes
                       |
                      com
                       |
                       my
                       |
                    MyFirstServlet.class

And now when I type [http://localhost:8080/SessionTest/index.jsp] at browser, it gives me 404 (page not found) error.

Tomcat is installed properly, because other applications are fine.

Please help me, what can be the problem?

Thanks.

Hi Rathi
can you type the url "http://localhost:8080/SessionTest" and then check whether your web browser shows jsp or not .

404 (page not found) here also....

:roll:

[jyothi malapaka]

Go to http://localhost:8080 and select tomcat manager.
login with the user id, password present in tomcat users for manager.
Then check if the application is running or if there is some error in it

Sorry, but what is the username and password for this...

Please tell me. where I can find it??

Thanks.

[jyothi malapaka]

<tomcat_installation_directory>-----conf(folder)----tomcat-users.xml
tomcat_installation_directory is same as catalina-home

In the tomcat-users.xml you will find an entry similar to (may not be same)
<user username="admin" password="" roles="admin,manager"/>
Just check the exact one in your xml file.

use this username and password for getting registered as manager.

Mostly whenever there is some mistake in web.xml you will get such sort of an error. Just check it

This is my tomcat-users.xml file:

  
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>
 

I tried all the combination, but it gave me 403 (access denied) error.

Please suggest me...

Thanks.

[jyothi malapaka]

Hi Rathi

add this code into the tomcat-users.xml
<role rolename="manager"/>
<role rolename="admin"/>
<user username="admin" password="" roles="admin,manager"/>

After that restart ur tomcat and try to login

Yes, My this application is not in the list. But how can add that into this list...

Please suggest.

Thank you for changing your display name, but last initials aren't accepted. You can browse the display name rules here.

Please correct your display name.

Deploy your web application.

If you are using advanced IDE's like WSAD (or) IntelliJIDEA they will do all the work for you. All you have to do is just configure your web/application server with the IDE.

No, I am using notepad for writing all code.

[jyothi malapaka]

hii could you send me your web.xml and the java file??

There might be some problem in it....
If you are sure that there is no problem in any of them ....then change the name of your SessionTest(web application) folder....
sometimes it works .....just try it..

And then restart your tomcat...refresh ur browser and check if it is present in tomcat manager...

[Ben Souther]

Have you looked that the logs under tomcat/logs?
If there was a problem deploying your app, you would see some messages there.

[ankur rathi]

<url-pattern>MyFirstServlet.do</url-pattern>
</servlet-mapping>

</web-app>

I changed name also but the same problem...

Please suggest some way...

Thanks a lot.
