Running a Servlet in a Maven Project using Tomcat

So I have installed Tomcat and that is working just fine. Currently I’m using Maven in Eclipse for a project. I want to run a servlet on tomcat with a maven project, how do I do that? It’s not as easy as just putting the files in the tomcat/webapps folder.

How to deploy Java/Spring application on my own system in Apache tomcat server.?

Hello all master minds,
I have created a java spring application in eclipse with mysql db.
Now I can run this application using >Run on server in eclipse,but I want to know how to deploy this application on my own laptop(windows 7).
I have already configured server,by localhost://8080 I can see Apache tomcat is configured.
Give me simple steps so that i can just run that software using browser via its link like
http://localhost:8080/PMS
PMS is my project name.
Thanks in advance.

You can install tomcat-manager in order to deploy your war using a web interface: Tomcat 7 manager
Another option is to copy your war file into tomcat webapps folder. Your container will auto deploy your war: http://tomcat.apache.org/tomcat-7.0-doc/appdev/deployment.html#Deployment_With_Tomcat.

The easiest way, since you are using eclipse is to just export your project as war and then put that war (naming it PMS) in webapps directory in your tomcat.
Once started, Tomcat will deploy that war on http://localhost:8080/PMS

You have to do the following steps:
Right click on project>> Export (Export as WAR file).
or if you are using a maven project then you can give a maven build.
Copy that WAR file, (you will get that war file inside the project folder in your workspace) to the tomcat_Installed_Folder/ webapps
Inorder to deploy the app from outside eclipse,
goto tomcat_Installed_Folder/bin
and double click on startup.bat
then you could see a console.
For detailed logs of deployment, goto tomcat_Installed_Folder/logs
ALL THE BEST :)

Missing spring-web.jar when deploying with WTP to Websphere

I've build a spring-based web project in Eclipse using Maven. Dependencies and class path are correct and the deployment assembly also lists spring-web*.jar correctly. However, when I deploy it using WebSphere 8 from within Eclipse the mentioned JAR file is missing from the created libs folder under .metadata.plugins\org.eclipse.wst.server.core\tmp2*\WEB-INF\lib . This JAR however is listed under the module section as a submodule for the container. I wasn't able to find out, why this JAR is listed there and why it is not copied to the LIB folder.
It works with a Tomcat server, it works when I export the WAR and deploy it manually and it also works when I manually copy the JAR to the lib folder.
Q1: Is this specific to Websphere?
Q2: Why is SPRING-WEB listed as submodule and what effect has this?
Q3: How can I automatically deploy it correctly?

This seems to be a bug in WAS as reported here
You can either copy the missing JARs manually or you can use the "Run server with resources on server" option in the "Publishing settings for WebSphere Application Server" server settings.

Deploying Spring MVC project

I've developed a small MVC project using Spring MVC, Hibernate, MySQL, Maven and Tomcat. I can run and test the application (locally) smoothly.
Now I need to publish/deploy this project on an (online) server that have only Tomcat installed on it. How can I publish/deploy the project online? Is there any special build I should do? What files I shall upload and to where?

There are several types of development options available.
For development on localhost EAR (Exploded ARchive) type of project is usually used (because you can easily make hot deploy on servery). But for production WAR (Web ARchive) is used (basically it's the same EAR archive, but compressed using ZIP algorithm).
If you want to deploy your project to remote Tomcat server then make your project as WAR archive and upload it to Tomcat's webapps directory. Then you might need to restart Tomcat. But it's manual way of deploying.
Better option is to use automated build tools (like Maven) which can compile your project, run unit tests, deploy on web server (local or remote) etc.
This one is a great example of how to deploy your project on Tomcat server by using Maven's tomcat-maven-plugin: http://www.mkyong.com/maven/how-to-deploy-maven-based-war-file-to-tomcat/
Good luck ;)

Do a mvn clean install and you will get a .war file in your target directory of web module.
Copy it and paste it in tomcat_home/webapps directory and restart tomcat. Thats it. now, you can access it in whatever configured port (eg: http://localhost:8080/<your webapp war name>). lets say your war name is myapp.war, then tomcat would have extracted it into myapp folder in webapps.
so your url will be http://localhost:8080/myapp

With maven deploy command, usually gets errors for various reasons.
if you work in Unix/Linux system, I recommend using "rsync" method on console. (You can write own shell script to manage easily). It helps not only deploying without a problem but also helps to get time while redeploying (only uploading changed / new files). Because maven deploy / redeploy uploads your project as a bundle in jar/war. However "rysnc" method uploads your project files one by one.
Before using it, you should sure that two conditions.
1- your project is built in target folder (Spring Tool Suite)
2- you have access to tomcat via ssh
example code : (v_ : prefix which is variable(customizable))
rsync -avz v_your_project_in_target root#v_ip:v_tomcat_name/webapps/v_project_name

How to deploy Java EE application using Jenkins CI?

I have Jenkins CI configured with a SVN repo of our Java EE based application.
I am able to build the application but I am facing problems while deploying the war. Actually I don't have any idea how to get a war file out of the build and deploy it to a remote Tomcat 7 server.
I need to deploy this code to Tomcat 7 in the form of a war deployment. Please guide me through any tutorial or docs.

If your build is Maven based, you could use the Maven Tomcat plugin. This will do more or less the same actions as the Jenkins Deploy plugin, but it will add a dependency on your build tool and not on your continuous integration tool.

There's a plugin for that: https://wiki.jenkins-ci.org/display/JENKINS/Deploy+Plugin
Basically, the deploy plugin will use tomcat's built in REST API/manager application to deploy the war file.
I use this in anger, and it's pretty simple. The plugin does everything you'll need for a simple situation.
If your needs are more complicated than this, you can script access to the management REST API directly, but I advise you to start with the plugin.
