KB44812: How to Change Graph Properties on a Report using the MicroStrategy Web SDK 9.4.x

The example provided in this document is provided “as-is” to the user and assumes that the user:

• Can program, compile (e.g. javac, jikes, etc.), and execute Java programs
• Can configure environment variables (e.g. JAR files, property files, etc.)
• Have all the necessary tools to create Java applications (JDK, IDE, etc.)
• Has access to the Strategy SDK documentation.
• Has read the customization warning at the bottom of this document

 
PREREQUISITES:
For the sample to work, the Strategy Web JAR files must be accessible by the Java Runtime
Environment. The Strategy Web JAR files can be found under:

• Strategy Web Universal (JSP): {web_root}/WEB-INF/lib directory.
• Strategy Web (.NET): Program Files\Common Files\Strategy directory.

Note:
More elaborate programs will require additional library files and are out of the scope of this document.
 
Users may want to change graph properties on the fly when a report is run. This can be done through an Add-on with the RequestKeys.

	}

       
	private static ReportBean getReportBean(WebComponent wc){
		ReportBean result=null;
		if(wc instanceof ReportBean){
			result=(ReportBean)wc;
        }
		else{
			for(int i=0;i<wc.getChildCount();i++){
				result=getReportBean(wc.getChild(i));
				if(result!=null)break;
            }        
        }
		return result;
	}
}

ADDITIONAL INFORMATION:
The Strategy SDK allows you to customize the standard Strategy Web interface, and extend and integrate the Strategy business intelligence functionality into other applications. However, before changing the way Strategy Web products look or behave, it is helpful to understand how the application is built. For more information regarding the Strategy Web architecture or the process of customizing Strategy Web, please refer to Strategy Developer Zone (https://resource.microstrategy.com/msdz/).
 
To access the Strategy Developer Zone, you must have access to the Strategy Knowledge Base, you must have purchased the Strategy SDK, and you must be current on your Strategy maintenance agreement. If you are a US-based business and believe that you satisfy all three of these conditions but you do not have access to the Strategy Developer Zone, please contact Strategy Technical Support at support@microstrategy.com or at (703) 848-8700. If you are an international business, please contact Strategy Technical Support at the appropriate email address or phone number found at http://www.microstrategy.com/Support/ContactUs.asp.
