I wrote a Java Application in IntelliJ Idea 13 and can start this application on a Tomcat 7 server. Now I want to test the application on a Windows XP pc. So I installed Tomcat 7 and XAMPP(for database) on the Windows XP pc. I got some files in my .../target folder like "projectname-SNAPSHOT" folder, "projectname.war", "generated-sources" folder and so on. So do I have to put all these files to my Windows XP pc into the webapp folder from Tomcat and start Tomcat? When I try it this way, I can't open the application when I go to "localhost:8080".
What files are missing to start the Application? Or do I have to compile all the java files again on the XP pc?
If things are built correctly and there are no external dependences (such as a database JDNI resource), you should be able to put "projectname.war" in the /webapps folder, start tomcat, and then browse to http://localhost:8080/projectname.
projectname.war should be sufficient in your "webapps" folder for most cases. Tomcat should deploy this automatically.

I have a linux vps, i had installed tomcat 9 and everything are working fine. But after i had deployed a Java Spring MVC war file to tomcat (let's call it example.war), when i pressed "start", it showed a message: FAIL - Application at context path [/example] could not be started (i used the tomcat manager). My Java Spring project used to be deployed by tomcat 7 plugin on my home computer.
java.lang.ClassNotFoundException: org.springframework.web.filter.CharacterEncodingFilter
Basically means that there is no class available in the classpath of your application.
This class is a part of jar spring-web-<YOUR_VERSION_OF_SPRING>.jar
So first open up your WAR file and check whether its in WEB-INF/lib folder.
If it isn't the changes are that it was deployed into the lib folder of tomcat 7 (that works) and in tomcat 9 both on your linux machine and development PC there is no jar like this.
Is there any way to run a war file on localhost without having the need to have tomcat installed on the machine? I have built a web application using gradle, spring and tomcat and I would like to be able to send the project as a war file to someone else and have them run it, even if they don't have tomcat installed.
Make it a runnable jar which contains tomcat inside. And then start the application with:
java -jar myWebApplication.jar

I have created an application in Java EE, I have learned how to deploy it in the tomcat server using the manager app or by copying the war file to the webapps folder. Now I can start the tomcat server only from the Netbeans IDE.
I want to know how to start the apache tomcat server without using the IDE and run my web application from the war file deployed. If I'm headed in the wrong direction please correct me. I'm asking this to gain knowledge of how to deploy the .war file in another server system without using the IDE only the tomcat server.
The shell scripts located in "CATALINA_HOME/bin" are the most bare-bones way of getting Tomcat up and running. The two scripts capable of starting Tomcat in this directory are named "catalina" and "startup", with extensions that vary by platform.
In your tomcat installation directory, there would be a startup.bat/sh file which will start the server for you. Moreover you can see the conf folder as well if you want to change any configurations. Whatever war you copy to the webapps folder will be automatically deployed
My team and I originally had a server running through Eclipse (Java EE), but wanted to switch it to running on the Tomcat 7.0 service found in Windows 2008 R2. We are completely clueless on what files to put where in the Tomcat folders found in program files. The entire server has gone down and we can't go back to the original setup. Any help is appreciated. All we're asking is where do we put our JSP/ROOT ect folders in the Tomcat program files.
Copying JSP files are not good idea rather you can package your jsp file into an archive file called WAR file. You can export your project from Eclipse IDE as a WAR file.
After creating the WAR file (.war), you need to find out tomcat installation directory and its called tomcat HOME. Now you just need to copy the WAR file into the following folder:
{TOMCAT HOME}/webapps/<project>.war
I'll add to the answer.
If you have folders of running applications from before you can put 'em under
{TOMCAT HOME}/webapps/
war file will un-zip after you start the service.
once the war is un-zipped, you can delete it, but only after you stop the service for the first time after war deployment.
I am not familiar with build processes on Eclipse with javascript (HTML5) and Java resources. But recently I got a war file from someone who asked me put it on tomcat (since the server where I used to access the project from is down). I tried putting it under C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps... and then I restarted the tomcat which I have mounted on eclipse... and then I thought I will be able to access the project using localhost
http://localhost:8080/<warprojectfilename>
But I get 404...
Could someone let me know how could I deploy it on tomcat and access it using localhost like a website.
Thanks
it looks like you have got some other Tomcat (or other server using port 8080)running on your machine... please check which tomcat instance is running and stop it, or stop any other server running service that you mentioned is working fine...
You can stop tomcat server by going in to tomcat/bin
and execute
sh shutdown.sh
or
shutdown.bat
in windows
and to deploy war file to Tomcat server :
1) go to your Tomcat path
2) open webapps directory
3) paste your war file here
4) restart tomcat
5) now you should be able to access your app
File -> import ->Web-War file this will import your .war as a web project.
goto Servers->tomcat->web modules-> add the imported web project. restart tomcat. you should be good
Since it was all static resource (javascript files)... I decided to extract the whole thing in a static web project on eclipse and it worked.
