Hotswap Spring Application with war deployed in Tomcat - java

I have an application built in Spring Tool Suite and using angular as well for frontend. I am building my maven and the deploying the war in Tomcat. While the Spring dev-tools work fine for any application when it is deployed form the tomcat container within STS but not when I put the war in external Tomcat. Is there any way to hotSwap the application other than blackboxing my javascript in Chrome. Can anyone list down the complete steps to follow. I'm a noob.
I have already put a dependency sping-devtools in maven. There are many answers related to that but none of them is working. It is a big project and takes 4 minutes to build and then I need to deploy it in tomcat which is a lot of burden.

Looks like you are looking to hot reload the static files. In IntelliJ, it's simple as saving your code changes and doing a Build Project CTRL + F9. It's even better if you install a Live Reload extension for your browser so that any changes made is refreshed automatically. There are also other similar options for compile & build automatically in IntelliJ as well other IDEs such as Eclipse.

Intellij built in Application Server

I was wondering if IntelliJ has a built in Application Server (like Tomcat) that I can use without having to download Tomcat directly?
Right now when I go to Run | Edit Configurations, Defaults, Tomcat Server, Local, it asks me to specify the Tomcat home directory.
Previously I had used myEclipse and it came packaged with a Tomcat so I would be suprised if the ultimate version of IntelliJ does not have this.
Intellij does not include built in application server. It has simple web server they refer to as Webstorm. However it is not application server.
Here is excellent resource (official docs) for working with application servers in intellij which you may find to be useful including tips on integrating it IDE via plugins etc:
Working with Application Servers
You need to download an application server manually.
Or you could use a Maven/Gradle dependency to start Tomcat programmaticly from the Main method, or a plugin for starting it via command line e.g. mvn tomcat:run.

Deploy Java EE project to WebSphere 7 WITHOUT Eclipse

I am getting tired of all the bugs in eclipse and m2eclipse, and would like to build with maven using the command prompt, plus afterwards start the server, and deploy the application to the server and publish it using the command prompt. Normally I do that within eclipse servers tab.
If I make a change to the code, then I should just rebuild with maven and republish.
I am aware that you can deploy an EAR in Wepshere admin web console, but it is not ear I am thinking of, at least I don't think so. I want to be able for example, once application is deployed, jRebel should be able to reload the clases in the jvm, but I believe the ear file is standalone so that wouldn't work.
So,
How can I start the server from the command prompt, plus deploy a project and publish it ?
Thanks!
You can automate the build so that it deploys the app as well, at least with Maven. Have a look at this post: Maven 2 and WebSphere:
WebSphere has (had?) a Rapid Deploy feature that you can use for "hot" deployments. Essentially it fired up a headless Eclipse for this, but it was much faster than a full EAR build and just as dynamic as going through WTP.
At the time, we had an Ant task that we used to copy the files over to the WRD directory. I'm not sure how that would work with Maven, but I imagine one could rig up something.

How to automatically deploy maven project from eclipse to tomcat

See title. I would also like the project to redeploy after every change. I am new to this area so my knowledge isnt that good. I tried googling and searching here, but I can't find any answer.
thanks for any help
There are two plugins that combined together in Eclipse work quite well together to perform what you want:
M2E: M2Eclipse which handles everything related to Maven.
Eclipse Web Tool Platform (WTP): which handles everything Java EE related (Tomcat, JBoss, etc...)
For M2E to work properly with WTP, you need to add m2e-wtp. You may find several useful information as well as some good links here.
I would start from the Eclipse Java EE distribution (it includes already Eclipse-WTP) and then add M2E (either with their update site or through eclipse market place: look for M2E and M2E-WTP).
From there, you create a Web Project and you can run it on a Tomcat server. The first time you try to run you project on a server, you will install Tomcat and it will appear in view named "Server". Double click on the server to configure ports, automatic deployment etc...
You can easily deploy a webapp using the Cargo Tomcat plugin. Here's helpful articles on this topic:

How to integrate maven generated vaadin project into eclipse vaadin plugin?

Eclipse Vaadin plugin has cool autobuild feature. Just clicking "restart application" in debug console will bring up to date application version to live.
Unfortunately importing maven generated vaadin project(using m2e) and copy-pasting .project buildCommands and natures from vaadin eclipse plugin generated project does not works.
I'm unnable to "Run on server...", tomcat does not deploy app for unknown reason. I can see app in wtpapps folder but it still does not deploys.
You can build your Vaadin app as a regular Java library, by itself (not as a WAR, or anything complicated). Then do two things: Create another project that builds the actual WAR file, and create another project that sets up Jetty for direct execution (google for details on how to get Vaadin operating under Jetty standalone, using Jetty as a library). With that in place you can treat your Vaadin UI like a regular java program (fast, direct restart through the standard debug window), and still have it be a WAR file for deployment.
See this thread for details on how to set up Jetty (look for Launcher).
I have also stumbled upon this problem some time ago and eventually found this:

It eventually helped me to get up and running after a scenario that has been very similar to what you have described.

Development Environment Java 6, Maven 2.x, Eclipse 3.4.x, JBoss 5 and JBoss Seam

I have to organize a development environment where I can run Maven projects with JBoss Seam, IDE eclipse 3.4.x and deploying to JBoss 5.
The projects that will run on this environment are based in Java 6, EJB3 and JSF1.2. The environment has to support hot-deploy.
I used to work in a development environment with Sysdeo Plugin to make Tomcat run all my applications - I've rarely used EJB (only for MDB's).
So I would prefer an environment similar to this.
I'd like to know what you guys use for the kind of architecture (what kind of eclipse plugins - if they work fine, things like that)
The thing I really didn't get right is why my Maven2 project with SEAM as a dependency packaged as EAR doesn't appear in my server (in Eclipse Ganymede - tab servers) for me to make deploy (right click - option Add and Remove Projects...).
Do I have to include an specific project nature to make my Maven2 EAR project visible to my JBoss AS included in my Eclipse Ganymede?
Seam doesn't appear to go well with Maven2. I'm facing some problems to make they work together - some dependencies appear to be missing and I have to put some extra files in some special places like seam.properties and components.xml with some special contents.
I feel like forced to use seam-gen and Ant. Too bad!
Not sure if this is helpful to you, but but we run the following
eclipse as IDE
mercurial for source code management
merclipse mercurial eclipse plugin http://goldenhammers.com/merclipse/
maven for builds (and m2eclipse)
mylyn with bugzilla for issue tracking
tomcat as application server
hudson for continuous integration http://hudson-ci.org/
reviewboard for code reviews http://www.review-board.org/
sonar for code quality metrics http://sonar.codehaus.org/
proxmox VE for virtualization http://pve.proxmox.com/wiki/Main_Page
Most things run on separate virtual machines to keep interference to a minimum. Proxmox VE is a breeze to setup (15 mins and you are running).
Hudson monitors the repository and automatically builds and tests each push.
If the war build is successful it is automatically (re)deployed (using a hudson plugin) into Tomcat and restarted.
I cannot recommend these tools enough.
HTH
I am currently working on the same environment you asked for, with the only difference I am running the app on a tomcat 6.0.18. I prefer to use tomcat 'cause it's so faster to run, and I don't use EJB for now.
Eclipse plugins :
maven : m2eclipse.codehaus.org
jboss tools : www.jboss.org/tools
web tools platform for hot deploying : www.eclipse.org/webtools/
I took the Eclipse Java EE version, I don't use seam-gen to create the basic architecture.
I don't have so many problems with this environment, sometimes the hot-deploy doesn't work and I have to manually clean files.
The only problem I had was with the separation of my app in two modules : eclipse wasn't doing the job well (not taking the last package of one module while building the other one), and I discover the option "disable workspace resolution", which works fine now.
Works fine. Hope it will for you.
