@Inject @Any does not work with @Stateless beans anymore

caarlos0 May 30, 2016 3:43 PM

I had the following code running in JBoss AS:

@ApplicationScoped
public class ReportGeneratorFactory {
 @Any
 @Inject
 private Instance<ReportGenerator> reportGenerators;

And the implementations are all like:

@Stateless
@ReportGeneratorQualifier(ReportGeneratorType.DAILY_CASH_FLOW)
public class DailyCashFlowReportGenerator implements ReportGenerator {

And:

@Stateless
@ReportGeneratorQualifier(ReportGeneratorType.SALE_PER_SELLER)
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class SalePerSellerReportGenerator extends AbstractSaleReportGenerator {

The interface is as simple as

public interface ReportGenerator {
    GeneratedReport generate(MandatoryReportGeneratorFilter filter) throws ReportGeneratorException;
}

But Wildfly 9 can't inject those beans:

org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001308: Unable to resolve any beans for Type: interface com.foo.reportgenerator.ReportGenerator; Qualifiers: [@javax.enterprise.inject.Any(), @com.foo.reportgenerator.ReportGeneratorQualifier(value=ITEM_SALE_PER_CUSTOMER)]

I can't just remove the `@Stateless` annotation because there are some `@TransactionAttribute` annotations and stuff.

What is the easy way out of this? Can I update maintaining the same behavior?

Thanks

Where does @com.foo.reportgenerator.ReportGeneratorQualifier(value=ITEM_SALE_PER_CUSTOMER) come from as it looks like it's included in the match(?)

Yeah, it happens for all impls apparently.

Anyways, the impl is like this:

@Stateless

@ReportGeneratorQualifier(ITEM_SALE_PER_CUSTOMER)

public class ItemSalePerCustomerReportGenerator extends AbstractReportGenerator {

@EJB

protected SaleItemsReportService saleItemsReportService;

@EJB

protected NotaFiscalItemsReportService notaFiscalItemsReportService;

Lets assume the interface and factory is OK. Take out all the implementations. Do a simple POJO

public class PojoReportGenerator implements ReportGenerator {
...
}

Does the injection see one implementation?

Add a

public class PojoReportGenerator2 implements ReportGenerator {
...
}

Does the injection see two implementations?

Make both implementations @Stateless

Still two implementations? Then add qualifiers etc. Also, make sure you use correct javax. imports for annotations and qualifiers etc.

I think the problem may be with the .ear deployment.

tree -L 1

.

├── META-INF

├── foo-business.jar

├── foo-public.war

├── foo-presentation.war

└── lib

The foo-business.jar has the classes cited, and the foo-presentation.war has a @Resource that injects the ReportGeneratorFactory.

The application.xml looks like:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE application PUBLIC

"-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN"

"http://java.sun.com/dtd/application_1_3.dtd">

<application>

<display-name>foo</display-name>

<module>

   <web>

     <web-uri>foo-public.war</web-uri>

     <context-root>/pub</context-root>

   </web>

</module>

<module>

   <web>

     <web-uri>foo-presentation.war</web-uri>

     <context-root>/</context-root>

   </web>

</module>

<module>

   <ejb>foo-business.jar</ejb>

</module>

</application>

beans.xml are all empty.

jboss-ejb-client.xml is:

<?xml version="1.0"?>

<jboss-ejb-client xmlns="urn:jboss:ejb-client:1.0">

    <client-context>

        <ejb-receivers local-receiver-pass-by-value="false"/>

    </client-context>

</jboss-ejb-client>

Maybe something has changed in the ear deployment in wildfly 9?
