shopping-api module classes not found in shopping-web

Question

I have created liferay project using versionportal-7.1-ga3. In web module, While trying to fetch list of Products and iterating that list in Web module ViewProductsMVCRenderCommand class, That time getting javax.servlet.ServletException: java.lang.NoClassDefFoundError: com/project/demo/model/Product, In this point api model classes and service classes not accessible in web-module .

I have exported model as well as service packages in shopping-api bnd.bnd file and Imported those packages in shopping-web bnd.bnd file, I also tried to import those service builder generated modeles and services with Import-Service OSGi manifest headers, But still getting same error. Here is my project github repository link https://github.com/vishwa-np/demo.git. After adding dependencies, package export and import, shopping-api and shopping-service module classes not finding in shopping web module.

Answer 1

In your shopping-web you are explicitly forbidding the imports (see the "!"):

Import-Package: \
    !com.pro...

I'd expect bnd to do the wiring for you if your dependencies are declared well, so you'd need not a single explicit import in bnd.bnd

When the module is generated for you, the wiring should be good. Or compare your code with this sample (use the branch for your version)
