I have a problem i'm triing to launch a war with the tomcat server.
In fact, when i click to launch the war (run on tomcat server) and i go to a localhost:8080, the page of the server says that no wars are on server.
I have try to put the war directly in the application folder of the server, but it's the same thing.
Can someone help me ?
Is it a problem with the war ? i have try with an other war, it's the same thing ?
I'm using a window 10.
Thanks you
.war is a archive file.
You Must Open the file. You can rename the file to .tar and use any Tar Tape-archiver implementation.
Or you can use 7zip to Open the file.
Install the Extension Tomcat for Java
Turn to Tomcat Servers in left side, and add tomcat
Right click the tomcat and choose start, after it's started successfully, right click and choose Debug War Package, this will debug the war, if you don't want it, just stop the debugging
Rigth click the war then choose Open in Browser:

I am new to java web programming and eclipse-apache Tomcat. I have small login web-application which includes (one jsp page , one servlet class).
I want to configure/deploy this application on apache web application manager. I mean I don't want to run this application in eclipse. I hope you understand my point.
Whenever I run my server in eclipse it run successfully. But when I want to open apache default page by typing http://localhost:8080 or http://localhost:8080 to configure my app It wouldn't open.
Please advice me.
To deploy a web application on Tomcat, you need to first compile your web application into a WAR file. Then, take that WAR file (let's assume it's called "MyApp.WAR") and put that into the tomcat/webapps directory. Restart the tomcat service. Tomcat will extract that WAR to a folder in the webapps directory. After that, any request to localhost:8080/MyApp will go to your webapp.
Make sure you have java installed, and add JAVA_HOME to your environment variable. (it is the path to java installation directory for e.g. C:\Program Files\java\jdk-1.6)
i.e
JAVA_HOME=C:\Program Files\java\jdk-1.6
install TOMCAT from here "http://tomcat.apache.org/download-70.cgi"
make sure you do not install it in you "c:\program files" due to some permission issues.
Lets say you installed tomcat at "c:\webserver\apache-tomcat\" this is your CATALINA_HOME, add it to your environment variable
i.e CATALINA_HOME=c:\webserver\apache-tomcat\
to acess tomcat webapp manager you need to configure user in %CATALINA_HOME%\conf\tomcat-users.xml
Add a role and a user :
Have your WAR file ready with you (this is how you create WAR "How to make war file in Eclipse")
move your WAR file to "%CATALINA_HOME%\webapp" directory. lets say "TestWeb.WAR" is your application with index.jsp page in it.
Now go to your %CALALINA_HOME%\bin and launch the startup.bat file (you would be using startup.bat to start and shutdown.bat to stop tomcat)
once tomcat is up and running check http://localhost:8080 is working fine.
P.S. If port 80 is already in use then try configuring your tomcat to some other unused PORT here "http://www.mkyong.com/tomcat/how-to-change-tomcat-default-port/"
go to your browser type http://localhost:8080/TestWeb/index.jsp
now you can to lot of configuration to your web app like having a default page and all
Hope this help you !
Normally eclipse uses Tomcat as an eclipse project, hence it uses metadata.
Server > Double click on the tomcat server instance > Server Location > Select "Use Tomcat installation"
Update: Tested just now. Set Deploy path to webapps folder. Works fine :)
I added my local tomcat 8.0.14 with eclipse successfully. My local tomcat is located at /Users/masum/tool/tomcat-8.0.14. I can see it form eclipse runtime Environment as well. Whenever I deploy any webapp to eclipse's tomcat. It doesn't appear in local tomcat-8.0.14/webapps directory. I expected it should go there. But it doesn't.
Also is I do any changes in tomcat/conf/server.xml. These changes doesn't effect in eclipse integrated tomcat. Also if local tomcat is running, port number conflicts with eclipse's tomcat. I have to stop local tomcat to work with eclipse tomcat. Looks like two different instance of tomcat.
My question is where does eclipse tomcat physically located? If I deploy any web app in eclipse tomcat where it actually goes? How can I configure Tomcat so that I can control it both from eclipse and also manually?
Thanks in advance.
Double click your tomcat server in the servers tab. In the servers tab you will see "Server path" under server locations. This is the location of eclipse's tomcat working directory. If you stop tomcat and undeploy all web apps, start and stop again, you will be able to select other options. Click "Use custom location" to set the location to a place of your choosing. In project Explorer you should see a tomcat folder. Under that folder you will find server.xml and the other config files, which you can modify as needed.
I have copied the sample.war file into the webapps directory of Tomcat, and I can access localhost:8080.
Now how will Tomcat deploy it, I mean do I need to open it in browser? How can I access the application?
You can access your application from: http://localhost:8080/sample
Deploying or redeploying of war files is automatic by default - after copying/overwriting the file sample.war, check your webapps folder for an extracted folder sample.
If it doesn't open properly, check the log files (e.g. tomcat/logs/catalina.out) for problems with deployment.
step-1. here I'm deploying pos.war First go to tomcat webapps folder and paste it
step-2. go to tomcat->bin folder start tomcat by clicking startup.bat
step-3. go to browser write localhost:port/project name eg. localhost:8080/pos (here my tomcat run on port 8080)
Done....
You just need to put your war file in webapps and then start your server.
it will get deployed.
otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
Manual steps - Windows
Copy the .war file (E.g.: prj.war) to %CATALINA_HOME%\webapps ( E.g.: C:\tomcat\webapps )
Run %CATALINA_HOME%\bin\startup.bat
Your .war file will be extracted automatically to a folder that has the same name (without extension) (E.g.: prj)
Go to %CATALINA_HOME%\conf\server.xml and take the port for the HTTP protocol. <Connector port="8080" ... />. The default value is 8080.
Access the following URL:
[<protocol>://]localhost:<port>/folder/resourceName
(E.g.: localhost:8080/folder/resourceName)
Don't try to access the URL without the resourceName because it won't work if there is no file like index.html, or if there is no url pattern like "/" or "/*" in web.xml.
The available main paths are here: [<protocol>://]localhost:<port>/manager/html (E.g.: http://localhost:8080/manager/html) and they have true on the "Running" column.
Using the UI manager:
Go to [<protocol>://]localhost:<port>/manager/html/ (usually localhost:8080/manager/html/)
This is also achievable from [<protocol>://]localhost:<port> > Manager App)
If you get:
403 Access Denied
go to %CATALINA_HOME%\conf\tomcat-users.xml and check that you have enabled a line like this:
<user username="tomcat" password="tomcat" roles="tomcat,role1,manager-gui"/>
In the Deploy section, WAR file to deploy subsection, click on Browse....
Select the .war file (E.g.: prj.war) > click on Deploy.
In the Applications section, you can see the name of your project (E.g.: prj).
In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).
Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.
There are two ways:
Either you can do hot deployment (Hot deployment means deploying when server is running/up).
Or you can do cold deployment (Cold deployment means deploying when server is stopped).
Just use tomcat manager console for console deployment or simply copy and paste your application in webapp folder of your server's tomcat_home directory.
Note: Make sure if your war file size is more than 52 MB (the default configuration value),
you need to make two little changes in web.xml file of Manager application of your webapp folder(Manager application is provided by Apache tomcat by default upon installing the server).
Go to the web.xml of the manager application (for instance it could
be under /tomcat7/webapps/manager/WEB-INF/web.xml.
Increase the max-file-size and max-request-size values in web.xml file:
<multipart-config>
<!– 50MB max –>
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
Increase the size by putting the values for <max-file-size> and <max-request-size> according to your requirement.
This has been working for me:
Create your war file (mysite.war) locally.
Rename it locally to something besides .war, like mysite.www
With tomcat still running, upload mysite.www to webapps directory.
After it finishes uploading, delete the previous version mysite.war
List the directory, watching for the directory /mysite to disappear.
Rename mysite.www to be mysite.war
List the directory, watching for the new /mysite to be created.
If you try uploading the new file as a war file, with tomcat still running, it will attempt to expand it before it is all there. It will fail. Having failed, it will not try again. Thus, uploading a www file, then renaming it, allows the whole war file to be present before tomcat notices it.
Hint, don't forget to check that the war file's owner is tomcat (Use chown)
If you installed tomcat7 using apt-get in linux then, deploy your app to /var/lib/tomcat7/webapps/
eg.
sudo service tomcat7 stop
mvn clean package
sudo cp target/DestroyTheWorldWithPeace.war /var/lib/tomcat7/webapps/
#you might also want to make sure war file has permission (`777` not just `+x`)
sudo service tomcat7 start
Also, keep tailing the tomcat log so that you can verify that your app is actually making peace with tomcat.
tail -f /var/lib/tomcat7/logs/catalina.out
The deployed application should appear in http://172.16.35.155:8080/manager/html
For deploying the war file over tomcat,
Follow the below steps :
Stop the tomcat. powershell->services.msc->OK->Apache Tomcat 8.5->stop(on left hand side).
Put the .war file inside E:\Tomcat_Installation\webapps i.e. webapps folder i.e. put.war (put.war is just an example)
After starting the tomcat(to start tomcat powershell->services.msc->OK->Apache Tomcat
8.5->start )
you will get one folder inside E:\Tomcat_Installation\webapps**put**
In this way you can deploy your war file in Apache Tomcat.
1.Generate a war file from your application
2. open tomcat manager, go down the page
3. Click on browse to deploy the war.
4. choose your war file.
There you go!
The application name goes into the context of your tomcat deployed URL,
eg. http://localhost:Port/applicationName.
If your application name is simple then, it should be http://localhost:8080/sample.
By default, Port is 8080, but if you wish to change it, or want to know the port where tomcat is running, simply go to server.xml file in <tomcat-apache-dir>/conf/server.xml, there you can find port & change,
eg. <Connector port="8080" redirectPort="8443" connectionTimeout="20000" protocol="HTTP/1.1"/>
If anything goes wrong, check the log files (e.g. <tomcat-apache-dir>/logs/catalina.out)
Perform the following steps:
Stop the Tomcat
Right Click on Project and click on "Clean and Build"
Go to your project Directory and inside Dist Folder you will get war file that you copy on your tomcat
webApp Folder
Start the tomcat
automatic war file extract and run your project
I followed the instruction in the following link, it works for me.
http://www.coderanch.com/t/487178/Tomcat/war-file-show-load
Stop Tomcat
Delete all the logs in tomcat/logs and all files in tomcat/conf/Catalina/localhost
Remove the war file and the directory it created (if it did) from tomact/webapps
Start Tomcat
While watching the logs, copy the war file to the webapps directory again
After this, keep an eye on the catalina.xxxx-xx-xx.log to find out the issue.
I am developing a dynamic web application on JBoss developer, but I am getting an error message:
Could not load the Tomcat server configuration at
\Servers\Tomcat v6.0 Server at localhost-config. The Servers project
is closed.
Even when I try to start the server on the servers tab, it doesn't start.
Any suggestions?
Sounds to me as if you're doing this inside Eclipse with WTP?
If so then you need to make sure that the Eclipse project called Servers which is created and maintained by WTP is open.
Open the Navigator view
Locate the Servers project
right-mouse click
Open Project
You have been closed server project in eclipse which will come by default after adding tomcat into eclipse. So try to open server project and start Tomcat it will Work..
Steps:
Go to project explorer.
Double click on server project.
You installed Tomcat v6 within eclipse using the “Add server” wizard and the “download and install” button.
You tried to start Tomcat and got the following error:
****“Could not load the Tomcat server configuration at /Servers/Tomcat v6.0 Server at localhost-config. The configuration may be corrupt or incomplete”****
How to solve:
1) . Close Eclipse
2) . Copy all files from TOMCAT_6_HOME/conf to WORKSPACE_FOLDER/Servers/Tomcat v6.0 Server at localhost-config
3) . Start Eclipse
4) . Expand the Servers project, click on the Tomcat 6 project and hit F5
5) . Start Tomcat from Eclipse
6) . Enjoy!!!
Just after many trying I got the solution for this problem. The problem is when your server is created using your IDE(Eclipse, JBoss or any) that time the server is not getting the configuration file. To resolve this problem you need to copy all the configuration files from the tomcat conf directory to your IDE server directory. If I will step out the solution than I can list the steps as-
Locate your Tomcat installation directory
Find the conf directory, sometime you will get it into skel directory
Copy all the files from conf and now change the directory to your IDE workspace
In Server directory paste all the files in your Tomcat configuration directory.
If you are using a Linux-based Eclipse:
Check user and group ownership and permissions to your server directory and subdirectories inside Eclipse. It MUST allow read-write config files by the current Eclipse user. Test it copying config files directly to it and, after that, accessing it through Eclipse text/xml editor.
It's usefull too to check the same for tomcat directory, because Eclipse may be bloked if its owner doesn't have permissions to access that files.
the solution to this problem is :
cd /usr/local/tomcat//conf
chmod 777 *
and it's done
I got the same issue. This is because it's missing "Servers" folder that contains Tomcat in Project Explorer. I already downloaded and configured my Tomcat, but after I created another new java web project, Server stopped working.
To solve this problem right click on "Tomcat v6.0 Server at localhost
[Strated,Synchronized]"
at bottom of your Eclipse.
click "General"
click "Switch Location"
click "Apply"
enter image description here
This usually happens when the "Close unrelated projects" button is clicked. A simple and straightforward solution to this issue:
Go to the bottom of the Project Explorer tab and there will be a project named "Servers". If it's closed, the icon will have a different color than the projects that are open.
Double-click on "Servers". Now the project will be open and this issue will get resolved.
I have copied the sample.war file into the webapps directory of Tomcat, and I can access localhost:8080.

If it doesn't open properly, check the log files (e.g. tomcat/logs/catalina.out) for problems with deployment.
step-1. here I'm deploying pos.war First go to tomcat webapps folder and paste it
step-2. go to tomcat->bin folder start tomcat by clicking startup.bat
step-3. go to browser write localhost:port/project name eg. localhost:8080/pos (here my tomcat run on port 8080)
