Tomcat starts but home page cannot open with url http://localhost:8080

Question

I am a newbie in Java, and I am trying to develop a web application. I have Windows 7 32 bit. I have installed Java 7 and set the path and classpath as well. After that I installed Tomcat 7.

When I try to open tomcat home page using URL localhost:8080, it does not open and Tomcat stops automatically.

Please help me.

Can you check the tomcat logs to see if tomcat encountered any error? It'd be under /logs. Please check catalina.out and localhost log files for any exception. And if there is, post them here. — Praba, Jan 09 '14 at 13:09
One place to check would be the log files for Tomcat. You should be able to find them in your /{TomcatDirectory}/logs/. Check the catalina.out file, it can sometimes give you some insight. — Russell Shingleton, Jan 09 '14 at 13:10

Make sure no other application using port 8080 before starting tomcat. If that's not the problem please paste tomcat log.

If you want to change tomcat's default port, go to tomcat folder and open conf folder, in which you can see server.xml. In that file you can see something like <Connector port= . Change the port value and start tomcat.

how can I check if other application is using port 8080 ? – Aniket Joshi Jan 09 '14 at 13:24

To check if an other application is using port 8080, you can use TCPview. See on the followig link http://supportlife.wordpress.com/2011/03/18/tcpview-identify-and-close-open-connections-on-your-windows-machine/ – Pracede Jan 09 '14 at 13:37

Why can't you edit the server.xml? that's not a reasonable constraint – NickJ Jan 09 '14 at 13:51
I am using windows 7 32 bit – Aniket Joshi Jan 09 '14 at 14:16
because it was located in Windows drive. You just copy your conf file into you desktop. Now edit. Then relocate to same position. – San Ka Ran Oct 16 '15 at 05:15
@AniketJoshi "how can I check if other application is using port 8080 ?" open cmd.EXE as Administrator and type `netstat -ab`, press Enter. You will see all the ports being used and what if anything is listening. – codeMonkey Jun 14 '18 at 16:14
Tomcat wouldn't start if another port is using 8080. There would be a bind error...so, this can't really be the answer given the OPs question....though this is often the answer if someone can't start tomcat as they've left a process running accidentally or something. – Brad Ellis Oct 02 '18 at 12:38

If you started tomcat through eclipse, It can be solved in different ways too.

Method 1:

Right click on server --> Properties
click on Switch location and apply.

Method2:

Double click in the server in eclipse.
Change Server location to Use tomcat installation(takes control of tomcat installation).

Your issue is not with port 8080, but with port 8005. Port 8005 is the shutdown port for Tomcat.

Rather than trying to figure out what is using port 8005, it may just be easier to edit TOMCAT_DIR/conf/server.xml and change the shutdown port to 8006

<Server port="8006" shutdown="SHUTDOWN">

thanks for your reply.I am trying to edit that server.xml but I can't save.Can you please tell me how to edit that file.thank you. – Aniket Joshi Jan 10 '14 at 06:52
You may find that the file needs administrator permissions to edit. Right-click your editor (notepad.exe - or whatever) and select 'Run as Administrator'. Then File > Open > server.xml – Will Keeling Jan 10 '14 at 07:17
This worked for me! Thanks. @WillKeeling , why did we have to change the shutdown port? – Pooja Sep 19 '18 at 11:59
This is a resolution if you get the error "SEVERE: StandardServer.await: create[localhost:8005]: java.net.BindException: Cannot assign requested address: JVM_Bind" as mentioned in the comments of the original post. – ap-osd Feb 20 '20 at 13:53

If you are using eclipse to start the server then check for the server location being used and the deployment path:

In my case changing this to Tomcat installation instead of workspace metadata worked for me.

For *Unix based systems, you can check the ports used by a particular application by issueing the following command in the terminal

[~/.]$ netstat -tuplen

You will get the list of all the ports that are being currently held and used by their respective process ID's

For windows user, type netstat -anin command prompt to see ports that are listening, this may come handy.

1) Using Terminal (On Linux), go to the apache-tomcat-directory/bin folder.

2) Type ./catalina.sh start

3) To stop Tomcat, type ./catalina.sh stop from the bin folder. For some reason ./startup.sh doesn't work sometimes.

For mac users

First Try : go to activity monitor -> search for java and kill the instance then restart the server and try.

Second Try: Check log file for any errors under tomcat logs folder.

Use below command to check tomcat logs in terminal

tail -f {tomcatpath}/logs/catalina.out

Third Try: Check if node or other apps using the same port. Use below command to check which app listening to a specific port. You will see list of apps with pid in second column.

lsof -i :8080 | grep LISTEN

Kill the process using below command

sudo kill -9 pid

My issue has solved.I was getting log as below.

SEVERE: StandardServer.await: create[localhost:8005]: java.net.BindException: Cannot assign requested address: JVM_Bind

My tomcat server was automatically stopping when I tried to open tomcat homepage with URL.

So I just made some changes in windows->System32->drivers->etc->host file. keep only 127.0.0.1 localhost and remove all other. your problem will be solved. Thank you guys for your help :D

If you have your tomcat started (in linux check with ps -ef | grep java) and you see it opened the port 8080 or the one you configured in server.xml (check with netstat --tcp -na | grep <port number>) but you still cannot access it in your browser check the following:

It may start but with a delay of 3-5 minutes. Check the logs/catalina.out. You should see something like this when the server started completely.
INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 38442 ms
If you don't have this INFO line your server startup is not complete yet. The problem may occur due to the SecureRandom class responsible to provide random Session IDs and which can cause big delays during startup. Check more details and the solution here.
Check your firewall (on linux iptables -L -n): You can try to reset your firewall completely iptables -F if you are not into an exposed environment. However, pay attention, that leaves you without protection therefore it can be dangerous.
Check your selinux (if you are on linux).

These are some of the most forgotten and not obvious issues in having your Apache Tomcat up and running.

I am using Eclipse Java EE IDE for Web Developers. Version: Oxygen.1a Release (4.7.1a) in Windows 8.1 x64 with Apache Tomcat 8.5.24 (for testing purpose).

Port Name & Numbers for my Tomcat Server are :

Tomcat admin port   :   8005
HTTP/1.1            :   8081 (my Tomcat Listening Port Number)
AJP/1.3             :   8009

Peoples, for those the Tomcat were running good earlier, and sometimes sudden after stopping tomcat server explicitly by pressing the below shown image button or may be other reasons.

Either they continuously failed to start/restart the tomcat with below said error:

Server Tomcat vX.Y Server at localhost failed to start.

or sometimes the Tomcat Server is started but instead of showing Tomcat Homepage in web browser, it is throwing client exception HTTP Status 404 – Not Found. in preferred web browser.

possibly, there are many reasons i.e. wrong Host name defined, Wrong Tomcat Server Locations defined in eclipse, project JDK/JRE version mismatch with Tomcat JRE dependent version, maven project version mismatch due to maven.compiler.source and maven.compiler.target version not defined under properties tag, mismatch version of project facet Dynamic Web Module to 2.5/3.0, Sometimes Tomcat Server is running on Windows Services level, previous stopped Tomcat port number were still listening and the processing pid were not killed in Tomcat defined timespan Timeouts Stop (in seconds): 15(by default) in eclipse and pid still running, failed to start in defined Start (in seconds): XX, etc.

Here I will give the resolution on, how to check and kill the running existing Tomcat port number's processing pid(beware, you must be aware with after effects).

In Windows, open you command prompt, and follow steps(my tomcat HTTP port is 8081):

netstat -ano | findstr :8081
TCP    0.0.0.0:8081           0.0.0.0:0              LISTENING       2284
TCP    [::]:8081              [::]:0                 LISTENING       2284

if any listening is being there, above command will list details of port listening along with processing pid at last of the line(here pid is 2284).

now kill the running pid like:

taskkill /PID 2284 /F
SUCCESS: The process with PID 2284 has been terminated.

also illustrated the above two steps like following:

Now, after resolving above illustrated reason, start the Tomcat Server.

I had the same issue. My tomcat was started but I was getting HTTP 404 page not found.However, in my situation, I installed tree instances of tomcat. Each instance contains conf, temp, work, webapps and logs folders. Unless I forgot, to copy the global web.xml under conf folder of each tomcat.

    e.g: /opt/tomcat/mytomcatInstance/conf/web.xml

The web.xml Deployment Descriptor file describes how to deploy a web application in a servlet container.

So even if my tomcat was up, my web apps could not be deployed properly.

Look in TomcatDirectory/logs/catalina.out for the logs. If the logs are too long, delete the catalina.out file and rerun the app.

In my case, the port that tomcat was running on was defined in an application.properties file for 8000, not 8080. In my case, it looked like the same problem described here. Just leaving this here in case anyone has a similar setup and issue! :)
