Hi
I am working with tomcat 4.1.37 and follwing are 2 problems i m facing.

1. After coming to tomcat web applicaiton manager page i see a list of applications. These are sample web applications that came when tomcat was downloaded. Now my problem is

When i click on any of those applications i get

HTTP Status 404 - /examples/

type Status report

message /examples/

description The requested resource (/examples/) is not available.

2. MYAPP is my application. I am trying to see the form.html(located in Tomcat 4.1\webapps\MYAPP). But i dont see MYAPP in tomcat manager at all.

If anyone can suggest me what to do it would be great.

Thanks
Lakshmi

Hello

To give few more details,the MYAPP application i mentioned above is a simple one with just form.html
the web.xml in the WEB-INF of MYAPP has the tag
<display-name>MYAPP</display-name>
<description>a basic application.</description>

I began with a basic application, sorry if its too simple to post in the forum.

Thanks
Lakshmi

Have you looked at any of the Tomcat logs to see what, if anything, is going wrong?

hi
thanks for responding

about problem number 1 that i mentioned above I see only the following update in the log after i clicked on an application.

2008-05-06 12:39:55 HTMLManager: list: Listing contexts for virtual host 'localhost'

Do i have to do anything with web.xml?

Thanks

Is this all that's in web.xml?
If so, I'd be surprised that there is nothing in the logs telling you why this app wasn't deployed.

BTW: Why are you using such an old version of Tomcat?
Help on forums like this gets harder and harder to find as your version gets further and further from being current.

hi
i had installed tomcat 6 version, i still get the same problem, when i click my application i get

HTTP Status 404 - /MYAPP/
type Status report
message /MYAPP/
description The requested resource (/MYAPP/) is not available.

no error message in logs. web.xml is

<web-app>

I have tried searching google but no use. It would be great if anyone can come up with some idea.

Thanks

Take a look at the web.xml heading in tomcat/webapps/ROOT/WEB-INF/web.xml.
Make sure yours looks like that.
Use the one that shipped with the particular version of Tomcat that you're running.

Also, what is the directory structure of your web app and where, exactly, is it located on your machine?

thanks for trying to help.

i checked, MYAPP/WEB-INF/web.xml and ROOT/WEB-INF/web.xml have the same heading.
directory structure of my application:
Tomcat 6.0\webapps\MYAPP is the application and it has form.html and WEB-INF.
WEB-INF has 2 folders - classes and lib(both empty) and web.xml
The location of my application is F:\LAKSHMI\Lak software\Tomcat 6.0\webapps\MYAPP.
Do you think environment variables have something to do with this problem?


thanks

Do you know if Tomcat is running?

Does http://localhost:8080 show you the Tomcat welcome page?

yes tomcat is running and i can see the tomcat page too. I am running tomcat on 1030 port as 8080 is being used by another application. http://localhost:1030 shows me the tomcat page.
Can you give me some info on what/how should the environment variables be? they are as follows right now

CATALINA_HOME F:\LAKSHMI\Lak software\Tomcat 6.0
JAVA_HOME F:\LAKSHMI\Lak software\jdk1.5
PATH F:\LAKSHMI\Lak software\jdk1.5\bin
CLASSPATH F:\LAKSHMI\Lak software\jdk1.5\lib

thanks

Hello,


I have a simular problem. I run the server Apache Tomcat - after installing Eclipse and Tomcat on a new computer - in Eclipse and haven't any problem: INFO: Server startup in 575 ms. But when I type http://localhost:8080/, I didn't get the Apache Tomcat Home Page, but get the following error message : HTTP Status 404 error in tomcat, The requested resource is not avaliable. What did I wrong?


Thanks forward.


Yours sincerely,


Emmanuel

Running web server from IDE and otherwise is different sometime.

Try running startup.bat from TOMCAT_HOME/bin and then try the url localhost:8080.

Hi Dev

Thanks for Response

Tomcat is working fine in Eclipse IDE. And also executing fine while I am trying to run the program in Eclipse.

But while I am trying manually from browser. Say like "http://localhost/8080" it showed me Oracle home page.
So I changed the port number of "server.xml" in "conf" folder in "tomcat" by following the link "http://lkamal.blogspot.com/2008/06/tomcat-how-to-change-port-8080.html".

Now when I try "http://localhost/8081" it is showing me the home page of tomcat. but when I am trying the application it is showing me the 404 status error.

Application deployment
tomcat6-->webapps--->DemoApp(Myapplication)-->WEB-INF-->classes-->servlet.java/servlet.java

I am also the providing the data presented in servlet.java and web.xml file


servlet.java

import java.io.*;

public class Servlet1 extends GenericServlet{

public void service(ServletRequest request, ServletResponse response) throws ServletException,IOException{

PrintWriter pw = response.getWriter();
pw.println("<html><body text=blue>");
pw.println("<h1> Servlets Demo Using Manual Configuration </h1><hr>");
pw.println("This is first servlet....");
pw.println("</body></html>");
pw.close();




}

}

Trying to understand the issue , you are facing.
Firstly can you confirm if post starting the Tomcat from the eclipse IDE , and then typing ttp://localhost:8080 on the browser , is showing the Tomcat page.

If Yes, then now your Tomcat server setup on Eclipse is okay.

Next question is , are you trying to change default Tomcat port from 8080 to 8081 ?
If so , what are the steps you followed and what is the error message it prompted ?

Hi Dev.

Thanks for reply


1) I started tomcat from Eclipse IDE and from my browser I tried to "http://localhost:8080/" it is showing me error message 404 status error.

2) yes I changed the port number from 8080 to 8081 by following the link "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

So , I guess http://localhost:8081 is showing you the Tomcat Welcome Page.
If Yes , then you query with propective to this thread is solved.

Could you list out what is the exact error you are encountering ?
Quick Tip ---> can you try the url-pattern as "*.htm" and try

From where are you starting tomcat?

As a starting point, start from bin folder and check in IE.

Then add Tomcat to Eclipse and start from ther and check in Eclipse

Then use the info in this thread to start tomcat in Eclipse and check in IE...

When I go to Go to section 'Server Location', the radio button and all the section was greyed out. Why is that?
Thanks,

On Server tab
>Select Tomcat Server (the one you are trying to start)
> Right Click - Select Open
> Go to section Server Location
>Selct Radio button for Use Tomcat Installation
>Set Server Path to //:the_tomcat_home_location
>Set Deploy Path to //:the_tomcat_home_location

i tried to solve this problem in this way as told by u:

On Server tab
>Select Tomcat Server (the one you are trying to start)
> Right Click - Select Open
> Go to section Server Location
>Selct Radio button for Use Tomcat Installation
>Set Server Path to //:the_tomcat_home_location
>Set Deploy Path to //:the_tomcat_home_location

but the problem is that section "server location" is not highlighted...so i am not able to make any changes there.
if anyone can tell me to highlight that section so that i can do changes it will be helpful

hey your url pattern is wrong
<url-pattern>firstservlet</url-pattern>
change it to
<url-pattern>/firstservlet</url-pattern>

Hey Guys ensure your tomcat server is up by visiting the following link http://localhost:8080
Then to run your jsp for example- If i want to run first.jsp

1. go to the tomcat installation directory C:\apache-tomcat-7.0.14\webapps\

2. Make a folder of your choice (navneet_examples in my case)

3. keep your .jsp files in this directory (first.jsp)

4. run your jsp by typing the following link http://localhost:8080/navneet_Examples/first.jsp

Hope it works for you

Well there is no use of this. I am running tomcat from exclipse and in my previous experience when i run apache outside in browser it works but if i run inside eclipse it gives the same error.

Now the situation its not running either way. I have Eclipse EE and tomcate 6.0 and when i try to run get 404 error. So no solution working so far. I changed the port to 8088 as it was giving error of already inuse. What to do now?
