How can I import a maven EAR project into Eclipse 3.4, and be able to use the IDE (WTP) to deploy the ear successfully to Weblogic (9.2)?
The main issue is that the dependent jars are not being included in the ear (under APP-INF/lib) when it gets deployed through the IDE. When I build from command line, the ear is exactly how I want it.
I am using the APP-INF/lib configuration for the ear plugin, and have included the jarModule sections for all the required jars.
When editing the eclipse EAR project's Java EE components, all the jars are listed, but not in the APP-INF/lib. Only when I open a dependent jar project do those specific jars get set under that subfolder. All the 3rd party jars are showing they will end up in the wrong place.
If you need more info, just let me know. Thanks!
You might want to use maven to create the eclipse WTP projects for you. This might be helpful.
The Using maven-eclipse-plugin in multi-module projects with WTP of the maven website describes how to develop Multi-module projects with Maven and Eclipse efficiently using the best of both Maven 2 and Eclipse's WTP. This covers projects that have EJB and EAR modules.
An fully working example of a multi-module projects, containing some JAR-, a WAR- and an EAR-project is even available for download if necessary.

I'm starting to use Maven (M2E) on Eclipse.
I have two projects
->Tools
->Main
The Main project requires the Tools project. I add "Tools" under the "Main"->"Deployment assembly" option, and when exporting to WAR, the WAR will automatically contain also Tools.jar. This is correct.
Now I installed M2E on the Main Project, to manage some spring dependencies. When I edit the pom.xml, Maven starts, and correctly downloads the Spring jars, but it removes the Tools project from the "Deployment assembly" option (it disappear from the org.eclipse.wst.common.component eclipse configuration file)
As a result, when I export the WAR from Eclipse->Export, the war will not contain Tools.jar, so the webapp will not work.
How do I configure pom.xml to do what Eclipse does with the "deployment assembly"?
That is, package all classes and resources and jar dependencies of the Tools project?
I think that I'm missing some understanding of Maven, but I've not been able to google about it?
thank you
I'm using the Eclipse "Internal Glassfish 3.1.2.2" server with the Eclipse Glassfish plugin (http://download.java.net/glassfish/eclipse/juno). I'm also using Maven with the m2e Eclipse plugin. The Glassfish plugin correctly deploys my EAR modules to the Internal Glassfish, but it does not deploy my dependency jars, which I believe should end up in a folder called "lib".
I found a partial solution here, which is to add my maven target lib folder to the EAR Deployment Assembly (double-click in the Deploy Path box to edit). This works, but m2e (or m2e-wtp) undoes the config change when I do Maven > Update Project.
There ought to be a cleaner solution. The Eclipse Ear Module Assembly dialog has a field to name the "EAR library directory", so it's aware of the lib folder. Where does Eclipse EAR assembly (without Maven) look for jars to put in the lib folder? I assume the Glassfish plugin is looking in the same place.
You can use the following steps to find the source of the problem:
Take Eclipse out of the equation and build EAR on command line using Maven, does it turn out ok? If not, look for a solution in your pom.xml.
If ok so far, open Eclipse and perform Maven -> Update Project. Then export EAR using Eclipse (look for EAR export wizard under File -> Export). Did the exported EAR turn out ok? If not, file a bug report for m2e-wtp plugin. It is still pretty raw, so it wouldn't be surprising if it doesn't setup Eclipse metadata correctly in some cases.
If ok so far, then it is time to look for a problem in Glassfish plugin. I doubt that you will get this far, but if you do I will help you to follow up.
We have a non-trivial multi-module maven project, then have a single module maven web-app that depends on 2 modules in the larger multi module project.
When we use eclipse to deploy to tomcat, it doesn't deploy all the jars that are required (spring, camel, etc) by the projects in the multi-module projects, but the multi-module jars are present???
But if we were to do an export of a war file on the single module app it includes everything we need spring, camel, and all the multi-module jars as expected? Why do export and deploy work differently and how can I get deploy to work the way I want.
We are using eclipse 3.6.2 with m2eclipse and other plugins. It seems Eclipse Indigo is worst at handling maven projects than 3.6.
This seems to be the same problem that I encounter semi-regularly. Open the build path for the project, and in the Exports tab, check the Maven dependencies checkbox. Do a clean and reploy the webapp.
It may be necessary to remove & readd the webapp to the server, and I usually have to quit Eclipse and restart it.
We have existing maven project. I have imported it with m2eclipse plugin.But
I can not run the project. Tomcat can not see resources(WAR files under target folder).
What am I missing? BTW we have multi-module project(2 WAR files).
Thanks in advance!
You need to add the tomcat server in your eclipse.
The maven project should be a web based project
You need to add the web project to the tomcat server.
You need to add J2EE Module Dependencies - Eclipse 3.3 ( To enable all library dependencies to be available at runtime to tomcat). Paths that point to your m2 repo & the lib files.
It may be Java EE Dependencies in earlier versions.
Both your projects needed to be added similarly.
Is there a way to do incremental deployments with these three tools when in a multi-module project?
Example of Maven project:
project
project-data
project-service
project-webapp
The above are Maven modules with dependencies between them. The project-webapp module contains the .war file, but I don't want to create a new .war file every time I need to deploy. Is there a way to perform deployments upon file saves?
Use the Eclipse WTP support (and either the maven eclipse plugin or m2eclipse to import your project as a dynamic project). Did you try? Are you facing any particular problem?
