I try to keep the deployments as lean as possible.

In case of Apache POI you recommended to patch the application server (like Wildfly) to provide the maven dependency and mark it as provided in the pom.xml.

  • How do you do this with Primefaces and Wildfly? It seems JSF extensions must be included in the deployment.
  • Does the same limitation exist with Quarkus?

Recently I was looking at various Jakarta EE components implemented by servers then found out underlying nio libraries like grizzly, xnio, Apache mina and Netty. I know Netty is popular among them. Read Blog post that Undertow 3 wants to replace xnio with Netty as well. Do you think we need give some focus on Jakarta EE space for underlying frameworks other than API spec. Idea I had in my mind only if I need simple servlet application which can be interchangeable with various nio frameworks with custom Java runtime image, not needed full Jakarta EE web profile.

I am working on a new project and would like to use Payara Micro, JPA, and JSF. I found an article you wrote on B-C-E called "Simplicity by Design" for Java EE 6 that is just what I'm looking for. What would be different today using Java EE 8 or Jarkarta EE 9.X ?

Thanks

When using microservices along with a rest client, it is suggested that each service is its own domain object and has its own database. If that is the case, then how would JPA work with mappings like OneToMany, ManyToOne, OneToOne? I've seen suggestions that a main database be used that would push views out to the other databases, but that seems to complicate the backend database server(s). Is there a specific technique for Java EE and microservices?

Thanks

Hi Adam,

How to handle large file upload to JAX-RS? In my project when I try to upload large file from a service to a Quarkus backend (using resteasy client in that service), I am getting exceptions:

org.apache.http.impl.execchain.RetryExec execute
INFO: I/O exception (java.net.SocketException) caught when processing request to {}->http://localhost:8080: Software caused connection abort: socket write error
...
javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request: java.net.SocketException: Software caused connection abort: socket write error
...
Caused by: java.net.SocketException: Software caused connection abort: socket write error

This only happens while trying to upload kind of large files (over >= 10 MB ). When I upload small files, it works just fine!

Thanks
