I've recently switched from Eclipse to IntelliJ Ultimate and have a question regarding locally testing a Tomcat app from within the IDE.
I have a /META-INF/context.xml file that needs to be deployed with the WAR when it is deployed on our remote Tomcat servers, but because of the way it is setup, this file cannot be used when testing locally.
To handle this in Eclipse, there is a "Servers" project where you can set Tomcat configuration like context.xml, server.xml, catalina.properties, etc. that is ONLY used when running the app from within Eclipse.
I didn't see anything similar to this in IntelliJ. Basically what I need is the capability to use a custom context.xml when running locally in the IDE and a different context.xml when deploying to the real remote servers.
I have a feeling this should be handled in the Tomcat Run Configuration within IntelliJ, but didn't see anything obvious in there.
Thanks!

I have a Java servlet application to maintain and have downloaded both the Live version and the Test version rom SVN to Eclipse (Helios) and have associated my Tomcat 7 with Eclipse to debug the applications. But when I attempt to Run or Debug the Test instance of the servlet on the associated Tomcat server Tomcat always seems to start the Live instance. For example when I attempt to start the Live Instance - in Eclipse it shows the URL to be;
https://localhost:8443/SWFinanceLive/WEB-INF/classes/path/to/web/request/entry/point.java
When I am expecting;
https://localhost:8443/SWFinanceTest/WEB-INF/classes/path/to/web/request/entry/point.java
How do I change the instance when running through the server in Eclipse?
This link seemed promising but then doesn't tell you how to change the setting;
tomcat server instance debugging in the eclipse
With the assistance of #Susie I was able to change the project root context. Things are working as I desire now
The deployment we follow is that we use runAssembler.bat to build an ear file and deploy it in a app server. We are using weblogic and jboss for testing purposes of the modules we built. However for every small change, we need to run runAssembler and build a new ear and deploy it in app server and restart the server.
I would like to find out if anyone figured out a way to do Hotswapping of class files which are generated by the code we write in ATG environment in either weblogic or jboss.
By attaching your IDE to your Application server on the Debug port it is generally possible to do hotswapping. Setting this up on Eclipse and JBoss is documented here, here and here. There is some information for setting it up in WebLogic here.
Attach your debugger, edit the java file, click 'save' and with hot code replacement in your IDE it should now update the running class file. In Eclipse it usually gives a popup if it was unable to do the sync. If you are using Eclipse, make sure the 'Build Automatically' flag under projects is ticked or you'll be waiting forever. I've not had any issues doing this via JBOSS (exploded ATG EAR) and variable success in doing this on WebSphere 7. It may also be prudent to make sure the same JAVAC you use to compile your build is the one loaded into your IDE compile path.
Another way to at least reduce the build/deploy time would be to deploy an unpacked/exploded EAR and simply copy your class files across (you could use the Eclipse FileSync plugin) and restart the server.
There are also some commercial options available, like JRebel
In our organization, we had good success in using DCEVM. It simply patches your JDK (in Windows: jvm.dll).
Download and patch your JDK
Launch your JBoss/Weblogic with the patched JDK
Set up Eclipse's Installed JRE's to point to patched JDK (restart and rebuild once)
Start the server, Launch debugger and connect
Ensure Eclipse's Debug view shows "Dynamic Code Evolution VM" (instead of something like "HotSpot VM")
Change your code, and voila!
You can do this with JRebel. After hotswapping you don't need to restart the server, only reload you deployment from Weblogic.
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.
I have a Maven project which is a web project and is packaged as a war.
I use tomcat-maven-plugin v1.2-SNAPSHOT to do a tomcat:deploy when i want to deploy.
But my question is how do i debug it / set breakpoints like i can do for normal web projects in eclipse (where a Debugging perceptive is shown and the server is paused.)
(i am a noob in this field)
[EDIT] I am not asking how to deploy to TOMCAT. i am rather asking how to setup the debug mode .FYI i am not able to right click on my project and select run> run on server, even though i have generated WTP specific files through maven.
mvn tomcat:deploy deploys an app to an external Tomcat server. If you want to debug that, you'll need to run that Tomcat server with debugging enabled and set up a remote debugging profile in Eclipse.
Edit: There's a succinct guide to doing this on the Tomcat wiki. The simplest approach is to start Tomcat with catalina jpda start. That will start Tomcat in debug mode listening on port 8000 for debugger connections. Then in Eclipse, you create a "remote" launcher configuration and tell it to connect to localhost:8000.
It doesn't matter whether you deploy it with maven or with Eclipse WTP as long as you started the server to which you deploy from eclipse and eclipse knows where the sources of the code you deployed are placed.
Keep attention if you have set the CATALINA_HOME environment variable, this will used to deploy to with mvn tomcat:deploy. But you can also define this in the configuration of the pom.xml.
<configuration>
<url>http://www.mydomain.com:1234/mymanager</url>
</configuration>
I'm not sure that it is feasible through the Maven plugin.
But you can generate eclipse specific files: mvn eclipse:eclipse -Dwtp.version=2.0 (The WTP version depends on the WTP version of your Eclipse).
Then, you can update your project and deploying it into a Tomcat like you can do for normal web projects.
This solution worked in my case, you can try this
Add module to Server
Go to the Servers view.
Double click on the Tomcat server.
You will get the server editor view.
Click on Modules tab in view (at bottom)
Click add External Web Module enter the path to your built files (e.g., C:\svn\projectName\trunk\test\project\target\webapp) and give a path.
Save.
Debug Server
Right-click on Tomcat in Servers view.
Choose Debug.
Debugging Startup
If you are debugging the startup of your application you might need to increase the startup timeout in the server view.
Thanks.
I am very new to Tomcat and web development in general and apologize for what may be a very silly question.
Consider 2 situations:
1.
I start Tomcat outside of Eclipse.
I use eclipse to create a war file.
I deploy it via admin console.
All is ok
2.
I start Tomcat via Eclipse
I can't access admin console
http://localhost:8080/manager/html greets me with 404 error
Same page is behaving properly when Tomcat is started outside of Eclipse
Please advise

You need to configure Eclipse to take control of your Tomcat installation. To do so:
double click on the Tomcat Server in the Servers view
under Server Locations, select Use Tomcat installation
This is illustrated on the screenshot below:
Eclipse creates a new Tomcat configuration separate to your Tomcat installation, in the 'Servers' project. This allows Eclipse to deploy webapps without interfering with anything you've done in your installation (via the manager app or by editing config files manually).
You can reconfigure Eclipse so that it uses the config from your Tomcat installation (see Pascal's answer), or to re-enable the manager app - but read the WTP Tomcat FAQ first as there are good reasons for it working the way it does. I don't recall ever needing to do this - the 'Servers' tab in Eclipse lets you deploy/start/stop/debug/configure apps as required.
