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 experimenting with a combination of Vagrant+VirtualBox+JRebel+Eclipse+Tomcat to develop a Java Servlet application. My Tomcat instance runs in a VirtualBox VM, which for Eclipse purposes means it is a remote server. I was able to get hot deploying (JRebel) and debug mode working.
I haven't yet found a good way to get the logs to show up in Eclipse, though. Ideally, I'd like something very similar to the Console view that Eclipse/WTP gives for local Tomcat instances. Some features I like:
Lines in stack traces are clickable, taking me right to the source file
Easily searchable
Highlighting (errors show up in red)
Shows up right in my IDE
Can be cleared when I'm sick of seeing too much
The first two features (clickable and searchable) are the most important to me. Does anyone know of a plugin or separate app that can accomplish this?
LogViewer appears to be abandoned (and possibly non-functional in current Eclipse versions), and JLV doesn't appear to have clickable source lines.
NTail might do the job. It hasn't been updated since 2010, but it seems to work on Eclipse Luna.
I have eclipse installed on a local computer, and am working on a project by myself. No one else is collaborating on the coding, I am doing it all myself.
Sometimes, I get ambiguous error messages in my spring mvc app when I run it on tomcat server using eclipse's run as...run on server command. For example, there is sometimes NO stack trace. In those cases, I would like to at least be able to see when each file in the app was last saved, so that I can try to figure out what I changed since the last time the app ran successfully. Ideally, I would like to also be able to see what changes I made to specific files.
Can anyone show me how to accomplish this?
Eclipse has Local History feature: try Team > Show Local History from context menu.
But I recommend you to use some version control system (svn, git) even if you work on your project alone.
So I've come across this weird bug in RCP Apps.
I've created a new RCP App with the Mail Template. I've added a new org.eclipse.ui.menus extension with a menuContribution with locationURI:toolbar:org.eclipse.ui.main.toolbar. To that, I've added a command with a little icon.
Now, if I start the app without Clear Workspace in the Debug Configurations, my action appears AFTER the Quick Access text widget. Not only that, but a few other bugs come along (e.g. views aren't closing, too many views are opening at once). This is not a one-time thing, i.e. I have to start the app with Clear Workspace each time.
This method of adding actions on the coolBar is non-deprecated. Why does it behave like a spoiled brat?
Without Clear Workspace:
With Clear Workspace:
There is a long discussion on the Eclipse forums about this here with a bug filed as a result here.
The bug is not scheduled to be fixed until Eclipse 4.4M5 but using one of the workarounds to remove the Quick Access control discussed here should help.
I have a number of users who complain of a problem with an applet what I wrote. Mostly it works fine then one day it stops working. Checking the settings shows that no Java plugin is available. Once the plugin is reenabled and the browser restarted then the applet works again. I have also observed that the settings show that no plugin is enabled but following a browser restart the plugin is reenabled (without intervention of any kind) and the applet works.
Anyone have ideas how the plugin might get disabled? This has also happened to me so I can be fairly sure that the users aren't fiddling with their settings.
The installations are a mix of IE7/8 and Java 1.5/1.6.
UPDATE
I'm not 100% sure about this but it seems to me that the problem occurs when another applet is running. Many users have IBM HOD and I'm wondering if there could be some kind of clash
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.
