Eclipse Redeploy/Undeploy Web Project without Restarting the Server - eclipse

In my eclipse web application I made a Web Project and a Library Project. The Web Project referenced the Library Project.
When I started the Server, every time I change a code in the Library Project and build it. The server wants to restart and it does not redeploy by the Web Project only. I do not want to restart the server because it takes a lot of time waiting the startup of the server.
Another is I am developing portlets using Liferay Portal and every time I change the Library Project, the auto-deploy of Liferay comes in but the Library Project Jar is locked and resulted to crash the portlet and did not deploy it until I restart the server.
Please Help!!!

In Java EE perspective find "Servers" tab at the bottom, delete your EAR out of there.

Try JavaRebel

If you install the nightly build of Liferay IDE (eclipse plugins for Liferay) it has support for delta-deployment where after the initial deployment (full deploy) it will only deploy the delta or just the individual files that you change as you save them (a single JSP or CSS file, etc).

WebSphere Liberty Eclipse won't publish application to apps directory

I have a 4-project, Maven-based EAR application (JavaEE-7.0) with a parent, WAR, resources, and EAR project. I am using Eclipse Oxygen with the latest release of WAS Liberty 17.0.0.2 and the latest release of the WAS Liberty plugin for Eclipse Oxygen.
I have no error markers anywhere in any of my files and Maven can produce an EAR.
When I try to publish to Liberty, nothing happens. I've done all number of possible cleans: workspace cleans, Liberty server clean, Maven clean, etc. but even though the server says [Synchronized], nothing ever shows up in the apps directory of my server.
The server is locally hosted on Windows 10 and I'm using JRE 8u141.
When WLP starts up, it says CWWKZ0014W: The application foo could not be started as it could not be found at location blah.ear.
I've tried nuking my WLP installation and reinstalling from scratch; still no dice.
(Cue rant about tools keeping me from getting work done...)
How can I resolve this?
Are you using the Add/Remove dialog from the Servers view to publish the EAR to the server? This works for me using my sample maven EAR project.
A few things to check:
EAR project's Deployment Assembly page references the other projects
The WebSphere Application Server Liberty Targeted Runtime is checked on the Targeted Runtimes properties page for each of the projects
Project > Build Automatically is turned on (or you've done a Build All) in your workspace
Your server's server.xml should contain an 'enterpriseApplication' element after the publish
If the publish still doesn't work, can you provide more details about your EAR's pom as well as how you created the project. (using an archetype? based off of a sample? converted an existing EAR project to a maven project?)

Running Maven project on glassfish server

I want to run web based Maven project on glassfish server. I am totally new on maven. However, i have successfully build the maven project and glassfish server is up and running also. Moreover, there is WAR file also in target folder but i am confused what is the next step to run that project on glassfish ?
Any help will be highly appreciated.
You have different options to solve this task:
If you are new to Eclipse I suggest to change to NetBeans. It comes with integrated support for application server deployments. You just add your maven (or nearly any other type of project like WAR, EJB and EAR) project and your desired application server instance (Glassfish) and you are ready: Right-click your project and choose Deploy and it'll get deployed to your server. NetBeans also supports hot-deployment.
You can deploy your WAR file manually in GLASSFISH_ROOT/glassfish/domains/domain1/autodeploy and it'll get deployed if your server is running. But this is not very efficient during development.
If you want to stay with Eclipse you can use the maven-glassfish-plugin or this maven plugin to do the deployment for you. I'm not sure which one is better but this topic is also discussed in this question and this question.

JBoss ejb3.0 instant hot deployment

I am newbie with jboss-eclipse. I have to work on javaEE5 with JBoss AS 5.1.0.GA. I don't want to use JRebel at the moment.
I installed "Eclipse Java EE IDE" with "JBoss Tools". I added the JBoss 5.1 Runtime server on eclipse and added a new ear project with :
an EJB3.0 class in ejb project;
a javabean class and index.jsp in web project.
I noticed when I make a modification in the jsp file, I can see instantly the changes after refreshing the web browser. That's ok.
When I modify EJB and javabean classes, there is no instant hot deployment. I have to restart the ear application (without restrating jboss server) or "full publish" the ear via eclipse to see changes.
Is there any way to have instant hot deployement for EJB and javabeans?
PS: I tried "incremental" publish but it hasn't worked.
Thank you!
You do need 3rd party tools for that, the most notable being JRebel. Without advertising I have to say this tool has saved me lots and lots of hours already while developing EE applications.
In jboss AS 7.1.1 you just have to go to the as admin console at localhost:9990 and select: Profile -> Core -> Deployment Scanners -> Auto-Deploy Exploded . You might also want to change the scan interval to something smaller. Afterwards, you may deploy your application for the first time by selecting "Run on Server". From this time on, your application will get automatically deployed whenever you change a file and it manages to compile.
I do not know if Jboss 5.1 has this feature, and if I were you I'd consider using 7.1.1 for development when it does not have it.
The hot deployment works fine with JBoss when publishing new files in your deploy folder, only class exchange will not happen in your currently deployed application.
That's why you see changes to all static content like HTML files immediately, but not changes to your java code.
In order to do activate them, you'll have to restart your application (not the whole JBoss, only your application, done for example in JBoss server view).
I have no practical experience with JRebel and I do believe that it saves you time, but you have to be careful with such tools, as they can introduce new problems which you spend much times in debugging, ending up in restarting the container and everything works fine.

deploying a war file in WTP(Eclipse) tomcat server

I have a maven build Java project.
My war file name is: test-1.0-SNAPSHOT.war
I am using M2E plugin in Eclipse.
I have run target mvn package.
Added server as tomcat version 7 in eclipse indigo 3.7. Server started. But my war file didn't deployed in the server.
I have tried by right clicking tomcat server and Add remove..., it says "there is no resources that can be added or removed from the server".
How can i deploy my war file in the eclipse WTP tomcat server?. Do i need to run any maven target?
Make sure that you have "Maven Integration for WTP" installed in your Eclipse instance.
First check if it's available through
Window->Preferences->Maven->Discovery->Open Catalog
If for whatever reason this does not work, you can get WTP integration from this update site (that's the version I am currently using):
https://repository.sonatype.org/content/repositories/forge-sites/m2eclipse-wtp/0.13.0/S/0.13.0.20110623-0455
This integration does a lifecycle mapping of maven-war-plugin into m2e architecture.
Once you've installed the WTP integration, you must restart eclipse and once it's restarted, right click on your web app project and choose: Maven->Update Project Configuration...
Also, I would advise to run a clean build at this time.
Last, but not least, delete and recreate your Tomcat server configuration (I don't know why, but I had to do it quite a few times when I switched to m2e).
I think eclipse is not recognizing your project as a web app, To confirm this
Open to do open J2ee perspective on your eclipse, If you open the project folder of your app, You should see (Deployment Descriptor)
If you don't see it, your app is not web app as far as eclipse is concerned
I have see this in case if you imported/created a maven command line project
To fix this
Select Project ==> Properties ==> Project Facets ==> make sure Dynamic Web Module check box is checked
If you do that the local tomcat server will add your app when do add remove projects
I think eclipse is not recognizing your project as web app,convert your project into web app by command mvn eclipse:eclipse -Dwtpversion=2.0 and try to deploy in Eclipse configured tomcat,it will work.
If you have Eclipse 3.5 or above you should ensure that you have both the m2eclipse (m2e for 3.7) plugin installed and its WTP add-on. With these you shouldn't need to change your configuration by hand.
Did you try to build your project from the command line and deploy it in Tomcat by hand?
By the way, have you read this wiki post? It's a bit old, but it may still be relevant.
Adding 2 cents to Prasanna wonderful solution.
I realized that building maven war files "mvn package" was just creating .war file but eclipse was not picking up that war but was deploying its some internal version of it's app war.
I found that server > Browse Deployment Location.. in Eclipse server view .. it was taking to some abstract location like "C:\Programs\workspaceSTS.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps"
Where I could see my exploded app deployed but it was not having any /classes folder just limited files.
Using Prasanna's method I realized that eclipse now was deploying full exploded .war now.
So this was happening coz changing the facets to Dynamic Web Module has actually populated "R-click project > Properties > Deployment Assembly "
This Web Deployment Assembly window only tells eclipse what to deploy and what not. So even if your project is NOT setup as Dynamic Web Module , and still if you configure "Web Deployment Assembly" values properly , eclipse will deploy the app fine to Tomcat/ Server.

How to redeploy the web app using the Eclipse IDE

Im new to Eclipse. I use Tomcat as my run time server, but every time I modified the jsp pages, Eclipse was still displaying the older one. Just wondering how to redeploy the application so the changes can be reflected.
Eclipse: Eclipse IDE for Java EE Developers 1.2.1.20090918-0703
Tomcat: Tomcat 6.0
Thanks
Doubleclick the server instance in question in the Servers view to open its configuration. Now, in the right top you should see a section called Publishing. Open it to verify and configure autopublishing settings.
Eclipse should do that automatically for you.
Otherwise, on the Servers view (Menu Window->Show View->Servers), you can right click on your Tomcat instance and hit "Publish" or "Restart"
Make sure you have the "JST Server Adapters" ("Web, XML and Java EE Development category") feature installed.
Eclipse's publishing functionality requries the project to be a "web project", and in some cases requires additional configurations.
Go to Windows > Preferences > Server > Runtime environments and add your tomcat
Either try using publishing, or (better I think) use the FileSync plugin. There you can tell which folders from your project should be copied (live) to what directory on your machine (the tomcat/webapps/yourapp). With a little more effort the filesync configuration can be made machine independent (only using one parameter as TOMCAT_ROOT), in case you want to check-in the project to a repository where others will use it.
Get the Tomcat plugin. It was nice because you can install Tomcat on your system and then associate your web app with that instance of Tomcat. The plugin will let you stop/start Tomcat and define a server such that when you do a build it knows how to deploy the changes. There may be some newer plugin but the Tomcat plugin worked for me and was fairly simple to install and use. Here is a page from IBM on using Eclipse and Tomcat. Inside that page it points you to the following: http://www.ibm.com/developerworks/opensource/library/os-eclipse-tomcat/
