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 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.
Actually I have to run my java war file having service which i want to access .normally in pc we run eclipse and use tomcat to do so. But in server if I have space then how to run my war file over there.
Basically you just install tomcat on your server and deploy the war file to it. There is lots of documentation on how to do this.
I would turn to the tomcat documentation on how to get started:
https://tomcat.apache.org/tomcat-8.0-doc/introduction.html
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
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.
Im having a jar file(for java classes) with some associated files of my project.Its bacially a client/server based application,but not web based.How can I run this program in a machine(24*7)?
How can i deploy it in any application server?
You don't need JBoss or any other application server. Just start it:
java -jar yourfile.jar
and it will run 24/7. To start it in the background, add " &" to it. If you look for ways to start it automatically, with the system your could use init.d (if on unix/linux).
If you want to use an application server anyway, just wrap your jar in a war file and deploy it. This can be done using Ant's War Task or maybe directly from your IDE.
