I am developing a Java application in windows that employs the use of a Tomcat server. I have added the Tomcat server into Eclipse and have been able to start/stop it by clicking it. I now want to be able to start/stop the server by code but have not been able to find a working solution. Please help!

I have two questions, for those which I did not get any solution sounds good for my expectations.
1. Why both XAMPP/WAMP and Apache Tomcat?
Assume if I am now running a Windows system, with Eclipse LUNA.
Now, if I have to run a query for my localhost server, how does Eclipse help?
I won't be satisfied if you say there should be an XAMPP server running live for your query to execute in Eclipse(Like they say here Database Development Using the Eclipse IDE, MySQL with Eclipse Data Tools Platform in Java).
Then why Tomcat is there?
Sorry if there is some loop hole, or may be this is a Banana-Monkey` type question. All because I don't get it clear.
And now, my second question.
2. How can I(Is it possible to) run a Java project in Eclipse with Apache Tomcat while WAMP/XAMPP is running in background in my system?
Suppose I am on the same system working with different user privileges. Say user1 runs both the XAMPP and Eclipse As Administrator. Now (or anyhow) is it possible to run a project in Apache Tomcat while WAMP/XAMPP is running in background simultaneously in the system?
I am totally confused. Helps with your comments and answers are appreciated.
Thank you.
Yes it is possible to run two servers on same system simultaneously.
Yes you can execute a MySQL query when XAMP/WAMP is not running.
It seems you don't understand your setup and the elements involved.
XAMP/WAMP contains Apache server, so a http server that can handle static html or run php scripts. It also comes with a MySQL database.
So the only important part from the Java WebAPP is the MySQL. You can start MySQL without starting apache, you can finally install MySQL yourself (it has simple windows installer). But if your application is using MySQL it has to be running for it to work (be it a XAMP version or standalone version).
Your Java Web Application requires application container to run, and it is the Tomcat. It is Apache Tomcat as it is developed under apache groupe, but it is not the same as Apache web server.
So you need tomcat to run your web app. Again you can install one yourself or use the one that comes toghether with Eclipse.
You can have many tomcats at the same time, all running (for example different version of Tomcats or Java) as long as they listen on different ports. The ports on which tomcat is runing is configured in its server.xml file under conf directory.
I'm very new to programming and i'm too lost.
I wrote a simple Java code on Eclipse (2 Classes) without any GUI and i want to access this simple Java App from any device in my LAN using a browser.
According to what i found on Google and Stack Overflow, Tomcat might help me.
Tomcat 7 didn't work on my Eclipse, so i'm using version 6 of it.
How can i make a GUI for my app?
And what do I need to be able to publish it using Tomcat?
Any help will be appreciated.
Thanks Everyone in Advance.
Tomcat is an application server. It means that you can write an application and then deploy it to a server (for example Tomcat). Then this application will be accessible on the server by some URL (for example http://localhost:8080/AwesomeApplication).
It only makes sense for web applications that handle some requests. You can't deploy an application with GUI, or simple console application to Tomcat or any other app server.
In language of final file representing your app - it must be a WAR file.
I have been working on a Java webservice using AXIS and Apache Tomcat. I have deployed it on a Server remotely and I am using eclipse to Run the web server.
When I log off from the machine the web service will be stoped.
I need to keep the web service always running no matter what. Its is better if eclipse could handle this.
I would appreciate a specific answers.
Is it possible to distribute Tomcat by Java Web Start and run it from there?
My application shall run within its own Tomcat server on the machine it is deployed on. Can I package Tomcat and the client application into one Java Web Start archive and run the Tomcat server and the client once the user has
downloaded the Java Web Start archive?
You cannot run a full blown Tomcat as it expects a certain layout in the filesystem and scripts and more.
You can however run an embedded web server in an application where you control it completely. I have done that with Jetty. You might find Howto embed Tomcat 6? interesting.
This might be possible if you signed all the jars correctly. But, it seems like this is quite a heavyweight solution. Have you considered doing this with Jetty?
I joined a project which has been already developed and its an Web Application deployed on Tomcat Server.
I have configured the Web Application on my local Tomcat Server and it is running fine. I want to start debugging the Application but I am not sure where to start from and how to debug an Java Web Application from Eclipse and so my question is
Q: How to Debug Java Web Application which is running on Tomcat Server on Local Machine in Eclipse Environment {Pointers to useful resources or other steps would be highly appreciated}?
There are at least a couple of ways to do this:
A quick search turned up a tutorial to use remote debugging in eclipse with tomcat to connect eclipse to the java process running tomcat.
If you create your project as a Dynamic Web Project using eclipses Web Tools Platform plugin then you can deploy to and debug tomcat from within eclipse easily.
Just stop your server from normal start mode and click on debug mode. Soon, after the server shows debugging,synchronised, continue using the web apps as you do normally. But before that, you must provide breakpoints and you can see the results that you need.
Works for me.
I have had to do this a few times. Often it is not convenient to create a Dynamic web project to debug a web application in tomcat. This technique is fairly simple but requires some configuration in tomcat and then using Elcipse (or netbeans) to attach to tomcat when its running.
http://wiki.apache.org/tomcat/FAQ/Developing, in particular
How do I configure Tomcat to support remote debugging? and
How do I remotely debug Tomcat using Eclipse?
First get the Java EE edition of Eclipse
You then need to have the Eclipse project containing the WEB-INF folder be a Dynamic Web Project. Then the full tooling becomes available and allow you to work with your projects inside any server including Tomcat. The trick is to locate the Server view pane, and right click to add a new Tomcat server adapter.
