We Keep Coding

What is the meaning of "The package is inside a non-bundle dependency" warning in a Maven project?

I encountered the warning when I imported my Maven project in IntelliJ:
The package 'org.xml.sax' is inside a non-bundle dependency
There are, in fact, 3 packages causing this: org.xml.sax, javax.servlet, and javax.xml.parsers. I have checked pom.xml and these packages weren't there except for javax.servlet.
Do I need to add the missing packages to the pom.xml? The program works but it would be better to get rid of this warning. I would also like to know if there are any expected problems when this warning is present.
This is the project's pom.xml

java.lang.LinkageError: loader constraint violation: when resolving method

I have the following:

2. Bean in the web tier
package web.x.y;

#SessionScoped
public class FileUploadViewAction implements Serializable {
#EJB
private FileFormatConvertor fileFormatConvertor ;
// Other declarations
if (fileType == Type.EXCEL) {
bytesToUpload = fileFormatConvertor.fromExcelToCsv(workbook, sheet, delimiter);

... 36 more
What am I doing wrong to be getting this exception?
So far I have done the following:
1. Check for cyclic class path dependencies
2. Move the ejb to web tier as managed bean (solves the problem but the bean is accessed elsewhere by other clients, making the business tier a more natural home)
3. Searched this site for similar problem/solution trails but have found none
Please help...

I got this to work. My answer is just to emphasize what mvera is saying here..
E.g. Both pom.xml content for war and ejb modules shared the following dependency:
<dependencies>
...
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.14</version>
</dependency>
...
</dependencies>
Here is what i did ...
Copy this dependency entry (and all shared dependencies) to the pom.xml in your ear module.
Mark the shared dependencies as provided in the pom.xml files of your ejb and war modules such that resultant dependency entry in the pom.xml files now looks similar to below
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.14</version>
<scope>provided</scope>
</dependency>
Rebuild your project!

You war and ejb.jar have each their own classloader, so each classloader has its own definition of poi classes.
You should try to put poi jars and all common jars to your ejb.jar and war in ear/lib. Mark dependencies as "provided" in you pom.xml for ejb.jar and war.
This way both war and ejb.jar will inherit of classes defined by their parent classloader, the ear classloader.
You should never try to pass a class defined in a classloader to another classloader but use a class defined in a common classloader.

When I build from the parent-dir and issue a command-line like:
mvn install
I get an error that the jar file cannot be found. What am I doing wrong?
[ERROR] Failed to execute goal on project iamws: Could not resolve dependencies for project ca.ubc.iamws:iamws:war:1.0: Could not find artifact ca.ubc.iam.core:iamCore:jar:1.0 in jboss-public-repository-group (https://repository.jboss.org/nexus/content/repositories/releases/) -> [Help 1]
It looks like it's trying to download my locally built jar file from an external repository, and I can't figure out how to fix that?

First of all you seem to have different artifactId, than module names. Although not a problem, it makes things a little bit harder to look at :)
When you issue a mvn install it will attempt to resolve the the pom files first to generate some effective POM files for the project, and that means that before it builds any of your modules, the parent pom needs to be resolved.
In the parent you depend on the iamcore module, but you haven't built it yet, and that's the reason why it fails.
Remove the dependency from the parent, and just put it into iamwebservice

I have checked a lot of threads discussing similar issues (sample) but none of the fixes provided are able to solve my issue. I included nearly all the dependencies but none worked.
Please help

issue was fixed once i removed optional from geronimo
i am able to run a GAE application with JPA :)

Make sure that you have the correct repository setup for the scannotation library.
According to mavenhub.com this should be declared either in your pom.xml or in your settings.xml:
<repository>
<id>thirdparty-releases</id>
<name>JBoss Thirdparty Releases</name>
<url>https://repository.jboss.org/nexus/content/repositories/thirdparty-releases</url>
</repository>
