I really don't know. I don't use Netbeans myself.
My tip is just this: Don't bang your head trying to come up with the ideal solution. Just toss those jars wherever works and keep coding. Fixing it later will be relatively easy anyway. And ofcourse look into EJB simplified packaging. I am using it myself and it's very convenient to be able to just put those jars in the WEB-INF/lib directory and be done with it. However it could be that it's not suitable for your project because I think not all features of full ears are supported.
Basically you are being bitten by one of the least understood parts of Java EE, packaging and dependency management / class loading. And you may include me in the list of people that don't really understand it. :)

hopefully when you will be implement this solution into production the build engineer will convert whatever you have to
1)ant build.xml
2)maven pom.xml
the double lib is weird i would first look at .classpath file for any possible <in>correct located library entries e.g.
<classpathentry kind="lib" path="$AXIS2_HOME/lib/xmlsec-1.4.1.jar"/>
Stijn?

Thanks Stijn and Martin,
Not having the ability to efficiently nest jars is a bit limiting, but certainly something I can get around through the build/deployment process. This leaves two questions:
1) Why doesn't Netbeans inform me of this during a build? I assume you don't want to error a build, in the event you're using an alternate ClassLoader (as you indicated)...but a warning such as "One of your dependencies has a non-satisfied dependency in the project, you doof" would be nice.
2) Why does GlassFish want the libs of these dependencies in <APP_ROOT>/lib/lib rather than <APP_ROOT>/lib? When I add those dependencies to the .ear directly (I tried this during my testing), it puts them in <APP_ROOT>/lib, so I still get the error. Flattening these libs causes code redundancy unless I do some build magic with the build/continuous integration. If that's the answer, that's fine...but I would think it would be something many people need/want to do and therefore a lot easier to accomplish. Anybody's experience in achieving a "clean"/complex build like this, I would be interested in learning your approach.
Martin, your explanation certainly helps me understand both what I am seeing as well as what Stijn explained - thank you.
I can't package everything in a war, in this instance, because I need MDB's as well. I took them out of the sample for simplification.
Thanks,
Steve

the <WebArchive/ApplicationArchive> classloader sees only the jars/classes at that level e.g. the uber-Application Classloader sees all jars/ears/rars at $GF_HOME e.g.
$GF_HOME\imq\lib
$GF_HOME\lib\install\applications
any package with a war extension would automatically implement the WebApplication ClassLoader e.g.
$GF_HOME\imq\lib\*.war
tlds are (supposed to be) located at META-INF folder of the WebAppName e.g.
$GF_HOME\lib\install\applications\WebAppName\WebAppName_war\WEB-INF\lib\web-ui\META-INF
does this answer your question?

Subject: FileNotFoundException for lib dependency...
Hello all,
I have a similar problem I have read about on this mailing list, however, I have upgraded to the latest GlassFish (which resolved the first issue) and a new (but seemingly related) issue has come up. When I attempt to deploy my .ear, which contains .jar libraries with their own dependencies, I get two FileNotFoundExceptions (attached: fileNotFoundExceptions.txt). Each of the Exceptions are a result of "nested" dependencies, and not from the first-level. By this I mean:
centralizedLogger.ear
|__ centralizedLogger.jar (my EJB)
| |__ configuration.jar (deploys fine - this was fixed recently)
| | |__ get_dev-common (exception)
| | |__ javax.persistence.jar (exception - needed because I have Entity classes in configuration.jar)
| |__ logger.jar
| | |_ javax.persistence.jar (exception - again, have Entity classes in logger.jar)
| |__ persistence.xml (for both the configuration.jar and logger.jar Entities)
|__ centralizedLogger.war (nothing significant)
The persistence.xml is working - I can see the Entities being "transformed" and my tables being created from the DDL annotations (as I requested in the persistence.xml file). My SLSB's deploy and my application-scoped Singleton SLSB starts up. Then, I get the lib file dependency problem looking for the libraries in C:/glassfishv3/glassfish/domains/domain1/applications/centralizedLogger/lib/lib/get_dev-common.jar (forgive me, I am forced to work on a Windows box at work).
The javax.persistence.jar file I am referencing is referenced from each project from the C:/glassfishv3/glassfish/modules/ directory. Shouldn't the class loader already see this and not need it again?
The deployment is "successful", as they were just warnings, and GlassFish sets up the standard file system structure under my domain. The application seems to work fully, as well (LogEvents are being persisted, all SLSB's deploy and are operational...). If I manually place the jars in the "expected" place (lib/lib), restart the server, no more complaints.
Obviously, I can just add the libraries to passify the validating checking...but seems like there is something wrong (especially since everything is working dispite the warnings during "TLD scanning".
Thanks,
Steve
