Package does not exist after upgrading to Netbeans 8.0.1 and Glassfish 4.1

I am learning JavaEE CDI and I created a small application with NetBeans 8.0 + Glassfish 4. After upgrading to NetBeans 8.0.1 and Glassfish 4.1, I got a lot of errors reporting that some packages do not exist. For example, I can’t use the following code because I get a message that the javax.enterprise.event package does not exist.

package jlacerda; import javax.inject.Inject; import javax.enterprise.event.Event; public class CMensagem { @Inject private Event<Evento> gerarEvento; public String getMensagem() { return "Hello world!"; } public void gerarEvento() { Evento evento = new Evento(); evento.setMensagem("Objeto criado a partir da classe CMensagem"); gerarEvento.fire(evento); } }

This situation also occurs with packages:

 import javax.enterprise.inject.Alternative; import javax.decorator.Decorator; import javax.decorator.Delegate; import javax.enterprise.inject.Disposes; import javax.enterprise.inject.Produces; import javax.enterprise.inject.spi.InjectionPoint;

If I changed the server to Glassfish 4.0, the same code will work as expected, and all packages will be correctly imported.

I searched the NetBeans and Glassfish forums, but I did not find a situation like this.

Thanks in advance for any question that may help me in solving this situation.

Glassfish 4.1 upgraded its version of CDI to version 1.2 (Glassfish 4.0 used CDI 1.1). Since you will not provide information on how your application is packaged, I will give you all the points to check:

  • Make sure there is no cdi-api.jar file in your war

  • Make sure that in your war there is no weld bound jar

  • Use Api CDI version 1.2 to compile code. Check the spec site to download the file or change the Maven configuration as follows

 <dependency> <groupId>javax.enterprise</groupId> <artifactId>cdi-api</artifactId> <version>1.2</version> <scope>provided</scope> </dependency>

There are no changes in the API from 1.1 to 1.2, but all OSGi settings have changed, so you may encounter a problem with these changes.

With NetBeans 8.0.x, you only need to open the "Project Properties", then go to the "Libraries" section and add the "Java EE Web 6 API Library". I have the same problem when porting from NetBeans from 7.4 to 8.0, but the solution is quite simple and obvious.
