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'm trying to add the SAP connector to Java Web Application and I'm using Eclipse and Maven to build the project.
I added sapjco3.dll at C:/Windows/System32 on my local machine and libsapjco3.so at /usr/lib64/ on AWS server (Amazon Linux 2) respectively. Then I added the sapjco3.jar file on pom.xml file like below to add the plugin and I have no problem building & running the app on my local machine and AWS server.
pom.xml
Problem happens when I replace the WAR file on AWS server and below message pops up:
tomcat log
It works fine if I reboot the tomcat server but I want to update the WAR file without reboot.
Based on the error message, I see that Tomcat server is trying to load libsapjco3.so again and causing the problem, which I don't know why java can't handle this. I guess either I need to add some logic somewhere to prevent loading libsapjco3.so twice or I just had set this up wrong and there is a proper way of doing this.
How can I fix this?
Amazon Linux 2
Tomcat 8.5.73
OpenJDK Runtime Environment (build 1.8.0_312-b07)
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 started my journey into web applications about three years ago and I'm happy to say that I've finally deployed a working website. My concern is that to deploy the website I use the Eclipse IDE and a Tomcat webserver. So basically I right click the project in Eclipse and then choose "Run As > Run on Server" and then select the Tomcat server I downloaded - from that point on the console spits out some startup messages and my website is online and ready for use. What are are some of the drawbacks of deploying a project this way. I've read just briefly about WAR files and adding them to Tomcats Webapps folder but I could neither get that working nor did I understand completely the process...so is it acceptable to just deploy the project the way I have been doing thus far by running it in Eclipse?
Generally Development machine and deployment server is different.
On Deployment server one may not have eclipse always.
WAR file is just a webarchive which includes all the necessary files. WAR makes your project portable.
Export WAR from eclipse place it in tomcat webapps in any machine and restart tomcat.
You should have your webapp successfully running on that machine.
That's a fine way for deploying a server when you're learning, or always have the server (the only server!) running on your development machine.
If you need to push to a remote machine, it won't work, and you'll need to learn other methods then, but for now, what you're doing is fine.
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
As the question explains I want to deploy a Java servlet based application which is developed on a local server (Apache Tomcat 6.0). I have the IP address, Host name for the new virtual server. I want to know, if it will be just a normal site migration process where I'll have to install Tomcat on the new server and configure the server, web XML files or is there a bit more.
As I have not done Tomcat config before. Any Help would be great
Is there a step-by-step documentation to perform this
Thanks
Download and install Java
Download Tomcat http://tomcat.apache.org/download-70.cgi
Read http://tomcat.apache.org/tomcat-7.0-doc/setup.html
Build your webapp into a war file with your build scripts
Copy the war file into webapps directory under your tomcat installation directory. More details can be found http://tomcat.apache.org/tomcat-7.0-doc/deployer-howto.html
I find it best to create a script that deploys my webapp from running my build script. And scp and ssh task comes in handy for installing it quickly. There are probably other maven tasks that might work for you.
