WBEM Services

The WBEM Services project is an effort to develop an open-source Java™ implementation of Web Based Enterprise Management (WBEM) suitable for commercial and non-commercial application. This project consists of APIs, server and client applications and tools. The APIs are based on Java Specification Request (JSR) 48 which has been submitted for approval by the Java Community Process (JCP) 2.0.

Take a look at the WBEM Services SourceForge Project Page too.

JSR48 Finalization

The JSR48 Expert Group is working to get the specification finalized. Then current goal is to have the spec done by the end of 2005. The WBEM Services code is evolving with the spec. If anyone would like to join the Expert Group please let Jim Davis know. Now start sending comments about the API to the development mailing list so that we can discuss them.

What is WBEM?

Web Based Enterprise Management is an Industry initiative to provide management of systems, networks, users and applications across multiple vendor environments. WBEM simplifies system management, providing better access to both software and hardware data that is readable by WBEM compliant applications.

WBEM has been designed to be compatible with all the major existing management protocols, including SNMP, DMI, and CMIP. WBEM is a DMTF standard. Industry standards used in the WBEM initiative include:

• Common Information Model (CIM)
• CIM Schema
• CIM Operations Over HTTP
• CIM to XML Mapping
• CIM to XML Document Type Definition (DTD) v2.0

What's New:

• 2004/11/1. Release of WBEM Services v1.0.2 is now available
• 2004/10/5. Release of WBEM Services v1.0.1 is now available
• 2004/3/22. Release of WBEM Services v1.0 is now available
• 2003/12/17. Added automatic generation of javadocs and changelog to the website. Occurs at hourly at 5 after.

WBEM Services License

The WBEM Services source code is available under the Sun Industry Standards Source License (SISSL) v1.2. Please read its terms BEFORE you download or checkout any sources using CVS.

WBEM Services Status

You can see the changes since the last release here.

The WBEM Services source code for the following components have been imported into the CVS Repository:

• CIM Object Manager (CIMOM). This WBEM Services component listens for WBEM client requests for CIM operations. Requests on CIM class definitions are handled directly by the CIMOM. Requests on instances of a CIM class are dispatched to the provider responsible for extracting the dynamic data for that CIM Class.
• CIM Repository. This WBEM Services component is used by the CIMOM to store CIM class definition and dynamic data.
• Managed Object Format (MOF) Compiler. This WBEM Services tool converts CIM class definitions in a text MOF file into CIM Repository formatted data. See doc/Instructions.html in the source code or executable downloads for information about how to use the mofcomp tool.
• MOF-to-JavaBeans Generator. This WBEM Services tool generates JavaBeans™ based on the CIM class definitions in a text MOF file. See doc/Instructions.html in the source code or executable downloads for information about how to use the mof2bean tool.
• Preliminary Java APIs. This source code represents a preliminary snapshot for Java Specification Request (JSR) 48 which has been submitted for approval by the Java Community Process (JCP) 2.0. WARNING: The APIs are subject to change pending final JCP approval.
• CIM Workshop. This WBEM Services graphical application allows you to browse the CIM schema and to perform operations on CIM Classes and Instances. See doc/Instructions.html in the source code or executable downloads for information about how to use this tool.
• Example client and provider programs with scripts to run them. See doc/Instructions.html in the source code or executable downloads for information about how to run these programs.

You can browse the CVS Repository to view these WBEM Services sources.

WBEM Services Downloads

A new release of WBEM Services v1.0.2 source code and executables are now available.

Release highlights:

• Fixed interop issue with getInstance for associations - the key fields in the associations were not getting set properly
• JAXP changes
• Method invocation with REF array now works properly
• Fixed NullPtrException when handling client event requests

NOTE: For now, the WBEM Services source code can only be built using JDK 1.4.x . Additionally, the WBEM Services executables can only run on JRE 1.4.x

WBEM Services Developer Teleconferences

No calls are scheduled at this time. Look for the next call sometime late 2005/early 2006.

Minutes of prior meetings NOTE: This is an archive of all emails sent to the wbemservices-development@lists.sourceforge.net.

WBEM Services Development

• Call into bi-weekly teleconferences (see above for schedule and dial-in information).
• Subscribe to the project email list wbemservices-development@lists.sourceforge.net
• Browse the WBEM Services source code from the CVS Repository.
• Download the WBEM Services source code from the CVS Repository via cvs checkout. If you are outside a firewall, you can follow the the instructions for anonymous CVS. Otherwise, you must create a Source Forge user account (if you do not already have one) and send us a request to add your Source Forge account as a WBEM Services developer. Then you can follow the instructions for Developer CVS.

For instructions on how to build, install and run WBEM Services executables, see doc/Instructions.html in the source code or executable downloads

WBEM Services Documentation

• Preliminary WBEM Services Java APIs (Generated daily). Browse online or download. If you download, find and open index.html in a browser. WARNING: The APIs are subject to change pending final JCP approval.
• Updated Solaris WBEM SDK Developer's Guide. Browse online or download. WARNING: These documents are updated versions of the Solaris 9 Early Access Beta documentation set but are not yet finalized. As such, they are subject of possible changes and will contain Solaris-specific WBEM information that may not apply. If you download, in a browser, find and open toc.html.
• WBEM Services MOF class definitions. Browse online. For each class, you can view a list of superclasses and subclasses, the class descripton and qualifiers, local (i.e. non-inherited) property descriptions and qualifiers, and a list of inherited properties. The classes are listed in a JavaDoc-like format.
• WBEM Services MOF class heirarchy. Browse online. The classes are listed in JavaDoc format. To view the heirarchy, select TREE in the right frame. To view as a full frame, select NOFRAMES

Other Open Source WBEM Implementations

The WBEMsource Initiative mission is to promote widespread industry adoption of WBEM by creating an environment for open source implementation. Currently available implementations are

• WBEM Services (Java)
• The Open Group's Pegasus (C++)
• SNIA Open Source CIMOM (Java)
• OpenWBEM (C++)
• SBLIM Standards Based Linux Instrumentation for Manageability. This is a related open source project that defines a Native Provider Interface for creating native providers written in C that can operate with any of open source CIMOM.
