Other environments must rely on external processes to transform the WSDL to something useful.,WSDL,.NET,Generated Code,ApplicationCode,SDK and its Components,Since our customers are not all .NET shops, we have taken steps to ensure an easy integration.,ReportNet ships with two pre-consumed libraries that are easily integrated with development environments.,1. Java,WSDL,AXIS,Generated JAR File,Development Environment,ApplicationCode,SDK and its Components,For Win32 programmers, such as Visual Basic and ASP, Cognos ReportNet ships with a COM implementation of the SDK. The generation of the COM dll is done prior to shipping, for convenience.,2. COM,WSDL,Cognos,Tool,Generated COM dll,Product Shipment,ApplicationCode,Development Environment (VB),SDK Introduction,Module 5 :,查询,Content Manager,Programmatic Access to Content Manager,Before we can query Content Manager for objects, we need to know something about SEARCH PATH,s,Access an objects search path from its properties,Programmatic Access to Content Manager,Attributes of the object are denoted by the symbol,Search Path Syntax,Please refer to the Cognos Developer guide for a more exhaustive reference:,/*,/folder,/*,/configuration/*,/content/package/folder/reportcontains(name,Product List,),SDK Introduction,Module 6,：,portal,集成,Portal,集成,url,Cognoslaunch,SDK,Jar,Dll,Access Manager Batch Maintenance,url,调用,Url,调用,Report Studio,Query Studio,Analysis Studio,Event Studio,Cognos Viewer,Q,&,A,
