How to deploy a war file in Tomcat 7

Question

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?

Answer 1

Manual steps - Windows

1. Copy the .war file (E.g.: prj.war) to %CATALINA_HOME%\webapps ( E.g.: C:\tomcat\webapps )

2. Run %CATALINA_HOME%\bin\startup.bat

3. Your .war file will be extracted automatically to a folder that has the same name (without extension) (E.g.: prj)

4. Go to %CATALINA_HOME%\conf\server.xml and take the port for the HTTP protocol. <Connector port="8080" ... />. The default value is 8080.

5. 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:

1. 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"/>
   

2. In the Deploy section, WAR file to deploy subsection, click on Browse....

   

3. Select the .war file (E.g.: prj.war) > click on Deploy.

4. In the Applications section, you can see the name of your project (E.g.: prj).

Answer 2

This has been working for me:

1. Create your war file (mysite.war) locally.
2. Rename it locally to something besides .war, like mysite.www
3. With tomcat still running, upload mysite.www to webapps directory.
4. After it finishes uploading, delete the previous version mysite.war
5. List the directory, watching for the directory /mysite to disappear.
6. Rename mysite.www to be mysite.war
7. 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)

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....

I followed the instruction in the following link, it works for me. http://www.coderanch.com/t/487178/Tomcat/war-file-show-load

1. Stop Tomcat

2. Delete all the logs in tomcat/logs and all files in tomcat/conf/Catalina/localhost

3. Remove the war file and the directory it created (if it did) from tomact/webapps

4. Start Tomcat

5. 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.

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

For deploying the war file over tomcat, Follow the below steps :

1. Stop the tomcat. powershell->services.msc->OK->Apache Tomcat 8.5->stop(on left hand side).

2. Put the .war file inside E:\Tomcat_Installation\webapps i.e. webapps folder i.e. put.war (put.war is just an example)

3. 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.
