Solaris WBEM Developer's Guide

Types of Providers

Providers are categorized according to the types of requests the providers handle. Client programs communicate with the CIMOM and access WBEM data through the client API. The CIMOM maps the provider methods to the corresponding client methods in the client API. However, the argument lists and return values of corresponding methods might differ. See file:/usr/sadm/lib/wbem/doc/index.html.

Ensure that your argument list and return type are correct for the method and class used.

The Solaris WBEM SDK provider types are shown in the following table.

Table 6–1 Provider Types


Class Name 




Supply dynamic instances of a given class, and support instance retrieval, enumeration, modification, and deletion 



Supply methods of one or more classes  



Supply instances of dynamic association classes 



Handle indications of CIM events 



A marker interface that indicates to the CIMOM that the provider does its own authorization check 

A single provider can act as one or more of the provider types by registering and implementing the relevant methods.

Provider Naming Conventions

You can include providers in a single Java class file or store each provider in a separate class. The provider name identifies the Java class that serves as the provider for the class. Currently, the CIMOM supports only providers that are written in the Java language.

Provider and class names must follow these rules:

Note –

You must prepend “java:” to every provider qualifier to notify the CIMOM that the provider is written in the Java language.

Follow standard Java class and package naming conventions to create your provider names. The prefix of a package name is written in lowercase ASCII letters and must be one of the top-level domain names (com, edu, gov, mil, net, org), or one of the English two-letter country codes specified in ISO Standards 3166, 1981.

Subsequent components of the package name can vary according to your organization's internal naming conventions. Such conventions might specify that certain directory name components are division, department, project, machine, or login names. For example, the provider name java:com.sun.wbem.cimom indicates the following information:
