When I work in on an servlet application in Eclipse, I have to choose Clean Working Directory in the server tab of Eclipse for the changes to be visible in the browser. Is there any way to make sure that I only have to build my servlet and the changes are immediately visible?
Doubleclick the Tomcat entry in Servers view, go to the Publishing section and select Automatically publish when resources change.
It by the way won't happen that "immediately". It might take around 3 seconds, you should see this activity in server logs. Although a slow starter, but Glassfish publishes in a subsecond. You may consider it instead for fast development.
Honesty, i do not think this is possible.
It is like programming in javascript and there is no way to see the result without clearing the browsers cache and reloading the page.

I have a dev machine, which deploys a java project to a local jboss server.
I have an IntelliJ maven project that has some html/js/jsp/servlets, etc. Is there a way to edit the code of the html/js files and then do a refresh of the webpage and see the updated changes without having to redeploy?
When doing just front end apps, I can accomplish this with a node server using gulp watch.
I'm hoping for something similar with my jboss server setup (intent is to simplify architecture and try to get the same front end development speed but have it all contained within a war). If I need to some how use gulp watch with maven, I'm good with that too, as long as I can make changes in the front end code (html/js, I assume changes to jsp/servlets would require a redeploy) and refresh the webpage and see the changes right away. I've also seen people write scripts to copy files from source into an exploded war before, but nothing that was automatic like gulp watch. My googles have failed me, anyone know how to accomplish this?
I have a question regarding updating a application on websphere application server. The application is already up and running and I just want to update the code which is packaged in a .ear file. Here is what I thought I should do:
stop the application server.
go to my enterprise application, select the one I am updating, and click update.
point to my .ear file in replace the entire application radio button option.
restart my application server.
After doing this and trying out my application, it is still running the old code, which makes me really confused. The only way I managed to get it to work is to use WinSCP, manually go to the cell directly/installedapps and replace the whole .ear folder. I dont think this a viable solution moving forward.
I solved it. After some intense digging it seems the binary files were expanded into dmgr profile but not my correct node. After finishing the update instead of clicking save I click review and there is a checkbox to synchronize the nodes, which then did the trick.
To update existing enterprise application we do not have to stop the application since WAS stops the application before updating the code .
Based on the update you gave i am assuming this is a network deployment manager setup , so possibly problem is with sync is not taking place after updating the app and save .
Are you explicitly invoking sync operation after application update ? If not , i would recommend that.
Still problem persists then most likely for what ever reason nodeagent process is not invoking app expansion into installedApps folder but you can take a quick look at nodeagent systemout.log file or ffdc files to see if there is any clue about expansion process.
As a work-around you can also use EARExapnder.sh/bat tool available /profile_home/bin directory to expand the application into installedApps when the app is really updated in config/cells/cell_name/applications but not under installedApps folder.
I hope this helps.

These opinions are my own.
I have created java Project with wicket in eclipse. the application works fine. The problem is, when I change the java code in the project and reload the page to see these changes, the changes do not appear.
The changes appear only when I run the project again (right mouse click on the project -> run as -> java application). Is there a way to see the changes after reloading the page without needing to run the project again every time?
Use debug-as instead. This will instruct eclipse to use hotswap and update your running application. Note that you'll still need to restart your application often since hotswap doesn't support all class file changes. For that you'll probably need to use a class-reloading solution, such as JRebel, or use the redeploy feature of a container.
Are you using Wicket >= 1.5? You might also be stumbling over the page version parameter that Wicket appends to every URL of a stateful page, e.g. ?5
If you simply reload the page with this parameter, the page will be rendered again, but not constructed new from the scratch, which might also lead to your changes being ignored.
It's quite annoying, but to get a proper reload of the page, you need to remove the parameter and hit enter.
I'm developing using IntelliJ 11u on a spring mvc application using tomcat.
I tried the maven jetty plugin, but after a few builds I keep getting java permGen issues and then it just hangs. I was told this was because spring uses log4j and it has some sort of leaks?
Anyhow, I'm asking for tips to help fire up a server, tomcat, with my updated code so I can make quick updates and have tomcat reloaded.
Here are my current annoyances with tomcat:
Only code changes seem to get auto-reloaded, if I make changes to my view pages things don't get updated unless I redeploy. The maven jetty plugin seems to map to my view pages directly and I saw updates to my view pages instantly w/o it even redeploying.
if I have more than 1 thing running in intelliJ, like say I have a main program that I run, or a unit test, IntelliJ seems to re-order what gets run in the run drop down menu and also the shortcut keys get changed to the last thing I ran.
I use google chrome, for some reason when I start tomcat it brings firefox to the forefront and opens a new tab each and every time.
If someone can address any or all of the above issues that would be great as I hate this dance I have to go through just to update/redeploy my application. I wish it could just be a consitant method, using shortcuts or automatically without me having to close the tab created in firefox, and then minimizie it, or redploy for a simple view change etc.
You should configure IDEA to update classes and resources and enable a checkbox in the Run configuration to do it automatically on frame deactivation.
Browser can be changed in IDEA settings and you can disable opening browser at all in Tomcat Run/Debug configuration.
As for the Run panel tabs order, you can pin tabs using the tab right click menu, in this case they will remain in the Run or Debug panel in the order they were created.
Look at JRebel if you want an even more productive environment (It costs, but I find it is worth it). As you can see here, http://zeroturnaround.com/jrebel/features/, it increases the types of changes you can hot-swap (no waiting for a build). I am currently evaluating it myself and will probably pick up a full license.
BTW, if you develop in scala (it looks like you're not, but just in case) the plugin is free.
I am using IntelliJ IDEA and developing web application in Java.
Is there any way that I debug my app without redeploy for any little change? the redeploy thing makes the working very slow and annoying.
Update action in IntelliJ IDEA is configurable, in case of exploded web application you can set what to do: update resources, update classes and resources, redeploy, restart the server. In most cases it's enough to update classes and resources. Update can be performed automatically on frame deactivation (when you switch from IDEA to the browser).
It depends what are you redeploying, JSP or raw Java class? If you change a Java class then IDEA will not compile it and redeploy by itself. If you change a JSP (pr JSF...) you can click package file (Ctrl+Shift+F9) from right mouse click menu.
If you use Netbeans, Netbeans does this for you. I am also fan of IDEA but I liked Netbeans due to this feature.
