So I'm having this issue with eclipse and tomcat 6.
I am able to upload the first version of my war on eclipse using server(tomcat 6)->add resource, add all.
But then I tried editing some lines, and then run as maven clean->run as maven install, then clean, clean tomcat work directory, and restart the server, and it would not show me the reflected changes.
Any suggestions?
You clean your application, and executing an install, but seems you're not executing the build correctly. Ensure you're generating a new war file (take a look at the date of when it is generated to make sure you're deploying the last version). If your project has many modules, e.g: war and jars. Make sure you build the jars as well, and the jars are being replaced in the tomcat/libs folder or in your WEB-INF/libs, check the date of when are the depending jars generated too, then you can see the differences.
Best regards.

I am using Jsf ,primefaces as front end and java files. Whenever i make changes i will run Maven copy the war file and paste into deployments folder manually. I want to autocompile whenver i make changes and deploy automatically
If your budget permits, you can use the proprietary JRebel product. You don't have to redeploy after every change.
Also, in your case, instead of manually copying the war file to the application server, you can use wildfly-maven-plugin
mvn wildfly:deploy
or
mvn wildfly:redeploy
I am pulling JavaScript from a jar as part of my build process. I wish this js to be part of my web resources for the app deployed on tomcat and I have updated my build process to allow this to happen. Doing a maven build (outside eclipse) works as expected and I can package up a war with everything in its proper order.
However, when building with eclipse I have run into some headaches. My understanding was in order to have web resources deployed to tomcat through an incremental build, I needed to put these build-time generated js files into the target/m2e-wtp/web-resources directory. However, when I publish these new files are ignored and the web-resources deployed to tomcat seem to be pulled from my source.
I also adjusted my project's deployment assembly settings. Through this I still don't have it working. I have the entry [source:/target/m2e-wtp/web-resources, DeployPath:/] which should find the newly generated files when I perform a "publish" to the server. However, the same thing happens where m2e-wtp seems to be pulling from source.
Am I missing something? How can I get standard behavior from m2e-wtp (i.e. make it comparable to a build done outside of eclipse)? Or can I have eclipse just build the war and deploy it as such (not do the incremental builds, I can sacrifice some speed)?
FYI (versions):
eclipse: (Using Spring Tool Suite) 3.2.0
m2e: 1.3.1
m2e-wtp: 0.17.0
tomcat: 7.0
Experiment added later:
After deleting my target dir, I performed a publish to Tomcat and all the web-resources were copied from my source. I also got a popup about files not found, most of which are compiled classes. However, it was looking for three files in the /target/m2e-wtp/web-resources/META-INF. Does the m2e-wtp plugin only look for specific files in a folder rather than the entire specified folder?
The problem is that the target directory was not being refreshed. Eclipse (or m2e plugin for that matter) doesn't recognize or care that files change in the target directory during a build, something that I was assuming. For now I have the auto-refresh (for the workspace) option on. The refresh on access option didn't working as it seemed to trigger the refresh only when I was publishing to tomcat for the first time.
I am using Eclipse 4.2 and JBoss 7.
I have Build automatically checked in Eclipse.
Even then I have to build and redeploy the EAR file to JBOSS to test any code changes I make in Eclipse debug mode.
Am I missing something here?
THanks,
What the "Build automatically" option in eclipse do is that when you modify the source code of a class, this one will be automatically compiled, which doesn't mean that all the whole project that contains the class (i.e. war, jar, ear ...) is redeployed in the server. But of course it helps in the speed of deployment, because the classes you've been modifying are already compiled when you manually build or deploy the project.
On the other hand, to avoid problems with redeployments, you'd better set up JBoss to delete the files related to the application keeps in the work directory, when the application is undeployed / redeployed. Look at this stackoverflow thread for more information.
Concerning the "Build automatically" option:
In order for the Deployment Scanner in JBoss to work, you have to have it turned on in JBoss.
Also, you need to add your project to the JBoss server in the Servers window. Look for the "Add or Remove..." option.
Once your project is added, any changes you make to your code will get detected and your module will be redeployed automatically in the background. Failing that and assuming your project doesn't have a snag, you can use mvn install & mvn jboss-as:deploy to manual update your module.
Beware, sometimes mvn doesn't pick up the latest java code. This seems to be a project configuration issue more than anything. Re-creating the project seems to correct the issue.
Also, keep an eye out for duplicate persistence.xml files.
You only need one.
I have an Eclipse Indigo installation with a JBoss 6 server managed by it. I have a Maven project with a few modules. These modules all build just fine from the command line.
One of the modules is an EAR. This is dependent on two JAR modules and a couple of WAR modules. When I package the EAR from the command line (mvn clean package), the EAR contains all the necessary JAR and WAR files. However, when I deploy it from Eclipse, the two module JAR files are missing from JBoss. The WAR files are just fine. Inside the "Add and Remove..." dialog the JAR files are also present, but not when deployed. I've checked JBoss' deployments folder and there they are indeed missing. The strange thing is, with the exact same POMs and code, all of my colleagues with the same(?) setup don't have this problem.
The two JAR modules are listed in the dependency management part of the parent POM. They are also listed as dependencies in the EAR POM. Still, Eclipse refuses to deploy them with the EAR.
Does anybody have any idea how I can solve this issue? I can manually package and deploy the EAR, but 1) that takes longer, and 2) I can't use Eclipse's debugging functionality this way.

I experienced the exact same issue, different eclipse (Eclipse Mars, WildFly 8.1 ).
The unsettling part was that I didn't change anything in the code or in the IDE (that I am aware of) and it started malfunctioning.
I suspect it has something to do with the cached memory of eclipse for it's plugins, anyway, after many hours of trying different things we fixed it by deleting the folder .eclipse under your user in windows.
Seems silly, but we tried everything except that, and that thing did the trick
I'm encountering a similar issue, however my environment is much, much simpler - being a web project, with a utility project. Not using maven at all and deploying to tomcat7.
The class file is not being deployed to the web-inf as expected, although the utility project is referenced, and marked as to be exported.
However with your issue, I came across this post:
http://blog.frankel.ch/better-maven-integration-leads-to-unforeseen-consequences-bugs#comments
which might provide a clue. Hope this helps.
I had the same issue. I didn't modify my code at all, I deleted all the projects from the work space, closed eclipse and reopened it. Then I did a clean and build of the project (which took much longer than before). This time when I went to add the EAR project, it had all the dependencies listed and actually worked.
I know there are a bunch of posts on this topic, but I can't seem to figure it out. Here is my setup:
- Eclipse Indigo
- Tomcat 6
- Struts WAR file that I imported into Eclipse from http://www.manning.com/dbrown/SampleApplication.zip
I added the server to Eclipse, and added the project to the server. It runs fine, but I'd like to make some changes to the XML and java files (not the jsp files). I was under the impression that Eclipse takes care of the deployment after I save and restart the server, but I guess this isn't the case. I looked into creating an ant file to do a custom build, but I'm not really sure how to make it since I don't even know how to do a deployment "manually". How would I go about doing a manual deployment? Thanks.
A war file is usually created by exporting it from an IDE like eclipse, netbeans, etc.
While generating a war file there is 2 options,
You can include your java files with it
You can avoid java files from it.
In both the cases class files will be there which are created from java files. Class files will be able to take care of the actions of java class.
If the war file which you down loaded is not having those java files, you will not be able to use it with eclipse, where as it will work fine if you are putting it into tomcat directory for running.
For running a war file manually just put it into tomcat webapps folder and run tomcat.
Then you can access the pages using the url.
http://localhost:8080/yourprojectname/
If you want to check whether the war file contains any java files, after starting the tomcat server it will extract the war file into the same directry, where you can search for java files.
If you want to run the project from eclipse,
import it into eclipse, open index.jsp page
right click-> run as-> run on server
if you have not yet configured the server yet,select the server in the list, specify its installation path, then add projects into server in next step, finish it. then it will load your project.
Please provide little more details so that we can help you better.
manual: copy the war in the tomcat folder then start tomcat.
if you want to use eclipse you need to click redeploy war first by right clickling the deployed war in the servers tab under tomcat.
