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.

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 have maven based project with following structure:
main_project
module_webproject
module_java_proj_1
module_java_proj_2
module_java_proj_3
... ...
Everything compiles and packages fine with command line maven goals execution. I need to setup this project into eclipse environment for developers with tomcat deployment. Anyone know setup instructions?
Also, i am looking into tomcat hot deploy for debugging capabilities.
I have tried mvn eclipse:eclipse, this does only creation of .project and .classpath files. But projects directories are not treated as java or web projects.
Answer from following forum some what helps...
[Running Maven project on Tomcat from Eclipse
There can be a few reasons why you don't see the project in the Add/Remove projects dialog for Tomcat. Verify the following:
You have m2e installed (http://eclipse.org/m2e/download/)
You have m2e-wtp installed (http://www.eclipse.org/m2e-wtp/download/)
Your Maven project imported as a Dynamic Web Application. Look for a Deployment Descriptor entry when you expand the project, it should be somewhere in the first few entries. It is the second one down for me on Eclipse Juno. Not there? It's probably not a web app. Go back and verify 1 & 2, then remove and re-import your project.
Make sure that your web application is not too new for the version of Tomcat that you are using. Right-click the project and go to Properties > Project Facets. Look for Dynamic Web Module and check the version. If this version is too new for your Tomcat version, Eclipse won't let you add it. For instance, your Dynamic Web Module version is 3.0 and you're using Tomcat 6.
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.
I started a new dynamic web project in eclipse helios. I integrated glassfish into eclipse and it works fine so far. Except one thing:
I place my libraries (jdbc, log4j etc.) in WEB-INF/lib. Eclipse deploys that files correctly to glassfish, but glassfish does not include that directory in its classpath, so my app won't run (because it can't find the jars).
When I edit the server's "launch configuration" in eclipse, I can manually add the libs under "Classpath", but that don't change a thing.
Only when I manully copy the jars to glassfish's lib/ext folder, the libs are included.
When I used tomcat as a server it works, the libs are in tomcat's classpath. But I want to use glassfish without copying the libs manually.
Any idea?
Not sure how do you add the libs in your project.
Try to show the project properties tab, select the Deployment Assembly node section, and click the add button. Select archives from file system or project (if your lib i also an Eclipse j2se project).
This should work.
Hoping you use the latest Eclipse 3.6 SR1 and the latest glassfish plugin from the update Center: http://download.java.net/glassfish/eclipse/helios
My servlet did not find the jdbc driver, so I thought it was a lib missing. Calling “ClassForName“ solved the problem. This seems strange to me, as this is not needed when used in the SE context.
So eclipse is correctly deploying the libs, just a little extra code is needed.
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.
