Access Cloud Connector data from Spring Boot

Former Member — Sat, 03 Feb 2024 21:00:19 GMT

I want to access data which has been served by the Cloud Connector and which is successfully connected to my Cloud Platform account. Now I want to access this data within a Spring Boot application and display the data on a web page.

But I get an error when I try to access the connectivityConfiguration resource:

javax.naming.NamingException: Cannot create resource instance

In Spring Boot I have no web.xml, so I try to do it this way:

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {
        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }
        @Override
        protected void postProcessContext(Context context) {
            ContextResource resource = new ContextResource();
            resource.setName("connectivityConfiguration");
            resource.setType(com.sap.core.connectivity.api.configuration.ConnectivityConfiguration.class.getName());
            context.getNamingResources().addResource(resource);
        }
    };
}

When I access the InitialContext, I see the connectivityConfiguration key in the list of resources, but when I try to access it like that:

Context context = new InitialContext();
Object conObj = context.lookup("java:comp/env/connectivityConfiguration");
ConnectivityConfiguration configuration = (ConnectivityConfiguration) conObj;

.. I get the exception I mentioned above.

Any idea?

I have the same issue (also without spring-boot, just spring framework). Any news on that?

I have two applications deployed and I missed the resource-ref entry in the web.xml of one of the web applications, but I needed it in both. So it wasn't related to spring at all.

Hope that helps someone.

Since you do not use the embedded Tomcat on SAP CP, you won't need the TomcatEmbeddedServletContainerFactory stuff.

I provided a context.xml including a <Resource> tag for the ConnectivityConfiguration and placed that file in "src/main/webapp/META-INF". Don't use "src/main/resources/..." also it is suggested for Spring Boot. Then you'll be able to lookup the JNDI resource...
