I'm not sure if this is a bug in Weld or Glassfish or if I'm doing something just plain wrong.
I have three jars: api, impl and base. These jars are packaged to war that is deployed to Glassfish 3.1 (b37). The outcome is an error that states that injection point is unsatisfied in a pojo that is in impl. The failing pojo to inject is in base jar. The curious thing is that I can inject that very same failing pojo to a backing bean in my war with no fuss, and I can also just instantiate the injection dependency by hand using the old fashioned new keyword.
Any thoughts? I also have Maven based test project that replicates this if anyone is interested to see that.
Every jar has beans.xml in META-INF - even the war has beans.xml.

This problem can be solved by replacing module weld-osgi-bundle.jar (Glassfish is shipped with weld 1.1.0.Final) in Glassfish modules directory with the newest one - 1.1.1.Final. After that remove all files from domains/domain1/osgi-cache directory.

Get Java EE 6 interceptors working (Weld on GlassFish 3.1)
I followed the above example and got it to work (i) in a maven project I created from netbeans
as a "war" and (ii) a maven project I created from netbeans as an "ear".
The latter was trickier as I had to add "empty" beans.xml files also to the ejb jar and the ear. (They were valid beans.xml files but had no interceptors or decorators)
./mavenproject2-ear/src/main/application/META-INF/beans.xml -> empty
./mavenproject2-ejb/src/main/resources/META-INF/beans.xml -> empty
./mavenproject2-web/src/main/webapp/WEB-INF/beans.xml -> interceptor for Logged
My Logged annotation worked fine when I put it on a stateless bean IN the war.
However it didn't work when I annotated the WebServlet with #Logged. Neither the class
nor the methods.
Am I missing something or is it just not possible ?
I have 2 modules: ejb and war, and ear module, that contains them. Modules build successfully, but when I try to deploy ear to glassfish, I recieve this error:
glassfish3.1.2|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=17;_ThreadName=Thread-2;|Exception while deploying the app [EarModule] : Invalid ejb jar [BackEnd-1.0-SNAPSHOT.jar]: it contains zero ejb.
Note:
1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message-driven bean.
2. EJB3+ entity beans (#Entity) are POJOs and please package them as library jar.
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (#Stateless, #Stateful, #MessageDriven, #Singleton), please check server.log to see whether the annotations were processed properly.|#]
I really don't know what to do, I've found a lot of questions like mine, but there was no solution.
I understood, what was wrong. The problem was in run configurations, I'm using Intellij Idea and in run configurations there was build and make before run of my ear module. I removed this and after maven install it deployed successfully.
You have to add an EJB into your WAR or EAR file. Just Create a new Class and annotate it with #Stateless
I know this is very build specific and it uses Netbeans instead of the OP's IDE but because I was lead here and this will likely be useful to some users:
I had the following build:
Netbeans Enterprise Application with Maven
Glassfish 4.1
Java EE 7
I had tried migrating from a previous non-maven enterprise application and the clone didn't quite work the way I expected, there was some old ejb jars lying around that I deleted.
I had done quite a few things to fix it:
Ensure theres no ejb jars lying around that shouldn't be there. Ensure that you don't have accidently have the ejb module jar included more than once as this can result in the same error too (Manually deploying the ear and deployment through netbeans sometimes gave me different errors).
I used the #Remote interface on my EJB applications. Now you should not be importing your EJB into your War, you should use the annotations correctly as described https://docs.oracle.com/javaee/7/tutorial/ejb-intro004.htm
(This is more of a note) When you update any of your war or ejb, clean and build them before cleaning and building your ear (sounds funny right?).
If you are using interfaces for your session beans then you should put them in a separate jar, make a new project maven > java application. Do the same thing with your persistence entities. Add these as dependencies to both your ejb and war project.
This doesn't relate to me in particular but you should have at least 1 #stateless (or I think #stateful) annotation in a java class inside your ejb module for it to run (for the module to be considered an ejb).
I likely had to do a few more things that I forgot but if you still run into issues comment below and I'll try to update.
Just try to build & install your project using Maven , and then , deploy it in glassfish ( do not run your project directly from your IDE )
I encountered this problem as well. It occurred when I had imported a new EJB project into my Eclipse workspace. The project didn't have a reference to the Glassfish libraries then, since it was not yet included in the EAR deployment assembly.
Upon saving the Bean file, the IDE automatically imported javax.inject.Singleton instead of javax.ejb.Singleton. This made the code compile without warnings, but throw the same error as in the original post.
A CXF JAX-RS application I have uses jackson to marshal POJOs to JSON. This works for the most part, but the other day it failed with a NPE when marshalling a deeply nested object.
After some investigation I found out that Jackson was included in Glassfish 3 (through Jersey) and after removing jackson-core-asl.jar, jackson-jaxrs.jar, jackson-mapper-asl.jar and jackson-xc.jar everything worked beautifully. I guess that Jackson 1.7.1 (included in GF3) had some bug that was fixed in the version shipped with my application (1.8).
Now the question is, why did I even have to do this in the first place? I would have thought libraries that are included in my war files should take presedence over any libraries in Glassfish's /modules directory.
Is there a cleaner way to do this than removing jars from the app server? Maybe there are other applications that depend on these jars ...
On a side note, the problem still exists with our GF2 container, but I cannot find any jackson libraries in the /lib folder (there is no /modules folder like in GF3). Any clues on where Jackson might be hiding in GF2 (if at all)?
Tell the Webapp classloader to prefer JARs provided by your WAR.
Add in your WEB-INF/sun-web.xml (or WEB-INF/glassfish-web.xml):
...
<class-loader delegate="false"/>
...
See http://jersey.java.net/nonav/documentation/latest/glassfish.html#d4e1927
consider using :
asadmin deploy --libraries ...
Ref: http://blogs.oracle.com/alexismp/entry/more_with_deploy_libraries
Jackson is included by Jersey and Hadoop, if you might be running Jersey or interact with Hadoop system; and versions included are often old. So this could be one source for "ancient Jackson" problems.
i have EAR and an EJB project. I noticed eclipse (sts) creates and earContent folder so I assume this is where I need to add external jars.
I added my hibernate and log4j jars on this folder but my EJB classes cannot resolve Logger class and hibernate classes.
What's the correct way of adding these jars? or should I just add them to the EJB build path?
Add jars to ear project EarContent folder
In Eclipse Right click ejb project, Properties
Deployment Assembly - Manifest Entries - Add
Choose your jars to add, OK
OK
jars now added to manifest in ejb project, should work.
I'm looking at this in a project for the first time, I'd be very surprised if there wasn't a better solution to this that doesn't require Maven. The Java EE Tools - Update EAR Libraries option looks particularly suspicious, but doesn't seem to do the above. Note I'm on Helios still.
Add those jars under folder EarContent/lib directly , then all is done.
I.E., EarContent/lib/foo.jar will work but EarContent/lib/dir/foo.jar won't.
I have been working on this problem for one whole day but in vain without any effective solution.
I have an ear file packaged with an ejb and a handful of jar files (including hibernate and the other dependent jar files).The ejb is stateless and enabled as a web service.
The ear file has been packaged using maven and has the below structure
ear->projectrelatedejb.jar
->hibernate.jar
->otherdependent. jar
->META-INF/application.xml
->META-INF/manifest.mf
The application.xml and manifest file are automatically generated by maven when I do a package.
When I deploy this ear file on glassfish it gets deployed with the ejb methods being accessible using web services. However when accessing the application (using soapui),
the ejb methods that perform some database functionality using hibernate throw java.lang.NoClassDefFoundError for the hibernate api during runtime.
It is obvious from the error that the hibernate jars are not on the classpath during runtime but since the jars are within the ear Glassfish should have
added it to the application classpath.
I tried various options like adding the classpath entries to the manifest.mf during the package (by using the element addClasspath with the maven-ear-plugin) which didn't do any good.Also with Glassfish we cannot add the dependent jars as modules to the application.xml unless the jars are application client jars
(Glassfish wouldn't deploy the ear file if the application.xml has the dependent jars declared as modules).
I also tried placing the jars in the lib directory within the ear (which isn't actually required) and with the manifest Class-Path header referencing the jars in the lib directory which also didn't fix the problem.
The quick and dirty fix which I can do to get this working is to place the hibernate and the other the dependent jars in Glassfish's lib directory.However,this is a bad practice
and I am somewhat reluctant to do it.
I would really appreciate if someone can provide me with a working solution to this problem.I have gone through the net looking for this problem
but couldn't find any solution.
Wondering if its a bug with glassfish or does glassfish need something special to reference the jars in an ear.
Thanks in advance.
I found a similar problem which is discussed here: http://www.tricoder.net/blog/?p=59.
Simply put, try putting the libraries in EAR/lib directory and according to JEE5 spec, glassfish will add them to class path automatically.
I used Server Library option to deploy application JARs and it worked for me.
Right click on your EAR-> Properties -> Libraries-> Add Library -> Create -> give name and change type in Library Type to Server Libraries then add JARs that should be deployed and confirm.
I work with NetBeans 7.0.1 and GlassFish server 3.1
When you say you added classpath entries to manifest.mf, which manifest.mf do you refer to? The one in ear-root/META-INF/manifest.mf ? Try adding a META-INF/MANIFEST.MF to your ejb module with Class-Path entries!
