Resource from the JDK is not available by default in Java 9. Here, I specifically request access to java. But the test still fails.
When I remove that requires clause and add a dependency as a library which contains javax. Resource , it works:. When I add them both Maven dependency in pom. If I add java. Do I do something wrong with my module description? How can I get access to JDK-supplied javax. Resource without command line switches?
Just to clear out some confusion here. The ways to work stated in the question by you are alternatives and should not be combined as you have already seen. Make use of the javax. Ideally this would be a preferrable option to stick to as the former is just an alternate to use the Deprecated module marked forRemoval.
So the required clause by itself it not enough to get access to a module No, the requires is just a part of declaration. The module marked as required has to be on the modulepath for you to access it. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

This may be specified for resources representing a connection factory of any supported type, and must not be specified for resources of other types.
Default: javax. Default: true mappedName public abstract java. The name of this resource, as defined by the name element or defaulted, is a name that is local to the application component using the resource.
Many application servers provide a way to map these local names to names of resources known to the application server. This mapped name is often a global JNDI name, but may be a name of any form. Application servers are not required to support any particular form or type of mapped name, nor the ability to use mapped names.
The mapped name is product-dependent and often installation-dependent. No use of a mapped name is portable. Default: "" description public abstract java. For field-based injection, the default name is the field name qualified by the class name. For method-based injection, the default name is the JavaBeans property name, based on the method qualified by the class name.
The name element must be specified for class-based injection. The type of the JavaBeans property the Resource annotation is decorating for method-based injection. The authenticationType element is used only for connection factory resources, such as the resources of a connector, also called the resource adapter, or data source. This element can be set to one of the javax.
This element indicates whether the resource can be shared between this component and other components and may be set to true , the default, or false.
The mappedName element is a nonportable, implementation-specific name to which the resource should be mapped. Because the name element, when specified or defaulted, is local only to the application, many Java EE servers provide a way of referring to resources across the application server.
This is done by setting the mappedName element. Use of the mappedName element is nonportable across Java EE server implementations. The description element is the description of the resource, typically in the default language of the system on which the application is deployed. This element is used to help identify resources and to help application developers choose the correct resource.
To use field-based resource injection, declare a field and decorate it with the Resource annotation. The container will infer the name and type of the resource if the name and type elements are not specified.
In the following code, the container infers the name of the resource, based on the class name and the field name: com. The inferred type is javax. To use method-based injection, declare a setter method and decorate it with the Resource annotation. The setter method must follow the JavaBeans conventions for property names: The method name must begin with set , have a void return type, and only one parameter.
In the following code, the container infers the name of the resource based on the class name and the field name: com. To use class-based injection, decorate the class with a Resource annotation, and set the required name and type elements:. The Resources annotation is used to group together multiple Resource declarations for class-based injection. The following code shows the Resources annotation containing two Resource declarations.
