For Beginners (readers of a tutorial?)

I would recommend to add

mvn archetype:update-local-catalog

below the package command (readme.md), someone might be wondering why archetypes are being installed but cannot be found anyways.

Example Does Not Work

Hello Friends,

I am trying to follow the tutorial located at the following URL: https://javaee.github.io/tutorial/connectorexample002.html

The tutorial did not run for me. I was able to start the mock EIS Java SE app though. However, the website deployed to glassfish that connects to this mock EIS did not work. I think the problem is that nothing uploads to my glassfish server. This has happened in the past in previous examples. I did not receive any obvious error messages via Maven, but when I went to the application running on the localhost I received a 404 error. One can see said 404 at the following URL: https://i.imgur.com/ZBtJVFq.png.

I tried to manually install the ear file to glassfish as I did with all the previous examples but this did not work. The application still showed a 404 error. I tried to install the ear, trading-ear.ear, from the following URL: C:\glassfish5\java_ee_sdk-8\glassfish5\docs\javaee-tutorial\examples\connectors\trading\trading-ear\target

When I tried to install this ear manually (asadmin deploy trading-ear.ear) I checked the server.log file and saw the following exceptions:

Code Mentioned in Tutorial Not Included

Hello!

I am following the tutorial at this webpage: https://javaee.github.io/tutorial/security-api004.html and ran into problems when I noticed that the example code does not include this directory tut-install/examples/security/security-api/built-in-db-identity-store or the source code mentioned in the example such as DatabaseSetup.java.

NPE

tutorial-examples/persistence/order/src/main/java/javaeetutorial/order/entity/Vendor.java

Line 112 in 9bf1d76

this.getVendorParts().add(vendorPart);

Hello. Maybe I'm incorrect, but NPE is thrown here during the data initialization in RequestBean. It happens because after creating a Vendor object, its vendorParts hasn't initialized yet.
