I have here a Web application being written in Java. Spring Web MVC is part of it. NetBeans 7.0 IDE being used. I deployed the app on Tomcat 6.0, it worked. Then I did it again, so since then it is undeploying the project. I can't stop the process using Stop/build command on NetBeans. I restarted the server but that did not help. And this issue is taking place for a while. Restart of computer helps.
What is the problem?
Best regards
This is probably an IDE/plugin issue interacting with the server process. Eclipse suffers from the same issues. Just restart your IDE and accept your fate.

At the moment, I'm developing a java web application locally(localhost) on Windows, using Tomcat 8.5 .
Unofortunately, I have no developing enviroment, so I have to do everything locally and then deploy to production via .WAR .
The issue is that the production application server (Linux RedHat) is running on websphere, if I generate the .WAR on tomcat, Will I have any problems to run it on WebSphere? Should I change anything in my code or web xml?
My system does nothing fancy, no hibernate, no spring, just a very classic mvc web application.
Thanks in advance
In general you shouldn't have to make any changes, but there are some differences between the two environments that could cause issues.
IBM provides a tool that will analyze your application and suggest changes that may need to be made. You can find more information here: https://www.ibm.com/developerworks/library/mw-1701-was-migration/index.html
I have a web application hosted on tomcat. It works perfectly fine if I run the tomcat by double clicking startup.bat file. However same application start showing lot of performance issues (high CPU and memory) if i deploy it as windows service. I am using following command to install it as a service
service install tomcat
Can anybody tell why it has performance issues if I install it as a windows service? Not sure what is difference as both are starting same tomcat server.

My issue got resolved by setting the memory configuration after installation of tomcat as a service. I referred this link https://plavc.wordpress.com/2012/02/08/tomcat-service-on-windows/

I'm working on a java spring web application. Every time I have a little change in application, there is no way for publish this change in weblogic except creating war file and deploy it to the server. I'm working on eclipse and I want to apply changes on live project in remote server(say 192.168.0.74 while I'm on 192.168.0.70). Is there any plugin or easy solution for this?
Thanks in advance.
For Eclipse development with WebLogic, install the Oracle Enterprise Pack for Eclipse to better integrate with WebLogic. You can then deploy to a remote server automatically.

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.
I've an interesting problem about start/restart of tomcat 5.5
I've deployed n webapps on my tomcat. All webapps work correctly.
Every time when I restart tomcat, never happen that all webapps starts.
If I "click" manually over tomcat manager start link of that webapp no started, that webapp start.
Can anyone suggest me any solution or idea for resolve this problem?
Thanks so much!

I have had issues with restarting tomcat in that the server does not finish stopping tomcat before it starts it again. Sometimes this results in port conflicts, but more commonly just bizarre behavior. I now make it standard practice to stop tomcat, verify no running tomcat/java processes (unix: ps, windows: taskmgr) and then start tomcat back up.
See if this is of any help :

(Though it is for version 4.4, you can search more on that website)
