Introduction
1IUntsriondgutchteioSnDK Java tutorial Using the SDK Java tutorial The SDK Java Tutorial is a series of code examples that show you how to do the following: Retrieve the list of Web Intelligence documents and universe files available in the repository. Refresh Web Intelligence documents. Manage prompts Activate drill mode, specify drill on a dimension, and filter on dimension values. Save a document and set the documents properties. Create and save a new document. Before you start The information in this section applies to all lessons. The following objects are created at login and used throughout the tutorial: IEnterpriseSession: This object is created when the user completes a successful login. ReportEngineobject is created when the user completes a: This successful login and is stored in the users jsp session variable. ISessionMgr: This object is created when the user completes a successful login and is stored in the users jsp session variable. IInfoStore: This object is created when the user completes a successful login and is stored in the users jsp session variable. Refer to the filelogin.jspfor information on these objects. Syntax specific to each tutorial is described before the code examples. For explanations of all other syntax, refer to theREBean Reference Guide. A document can be opened in 2 different ways: Using the document ID. Using a storage token. When a document is refreshed, a new storage token is created. This token can be used in another jsp page. Opening a document using a storage token provides better Web Intelligence server performance than using a document ID. Refer to theCustomizing Web Intelligence with REBeanguide for more information.

Navigating through folders
NaOvviegravitienwgthroughofdlers
2 Overview This chapter describes how to navigate through folders in the Central Management System (CMS), and retrieve a list of documents and universes. Before running this tutorial, you must understand how to navigate through folders and categories to search for Web Intelligence documents and universes using InfoView. The code used in this tutorial to navigate and view available Web Intelligence documents can be found indocNav.jsp. The code to navigate and view available universes can be found inunvNav.jsp. The following table helps you keep track of your position in the tutorials. The current stage is highlighted. Stage You learn how to...

Navigating through folders All sub folders that contain Web Intelligence documents are created under the root folder (with id 0). The root folder is created when Web Intelligence is installed. To list folders stored in the CMS, you must first open the root folder, using the root folder ID; it is then possible to list sub folders and create a sub folder navigation functionality.
SDK Java Tutorial 7
In this tutorial, when you open a folder, available sub folders and Web Intelligence documents are listed. The code used to browse sub folders and retrieve the documents and universes is described below. Navigating through folders to list Web Intelligence document in the CMS ThedocNav.jspscript uses the following steps to implement the navigation functionality. 1.sID from the HTTP request parameters. The sIDRetrieve the variable parameter is the unique ID for the top folder to be listed. If this parameter is null, the root folder ID (0) is used automatically. 2.Retrieve and list theIInfoObjectrepresenting the top folder. 3.Retrieve theIInfoObjectssub folders contained in the toprepresenting folder. Create links to docNav.jsp for each sub folder, pass the ID of the folder to be navigated in the sID parameter. 4.Retrieve and list theIInfoObjectsrepresenting Web Intelligence documents contained in the top folder.
8 SDK Java Tutorial
The folder navigation functionality To retrieve a list of folders on a Web Intelligence server, the CMS has to be queried. A query is run using theIInfoStoreobject. In these tutorials the IInfoStoreis created when the user logs on to the Web Intelligence server, it is added to the users jsp session attributes. To retrieve folders or documents in the CMS,TCEJSCINI_OBFOmust be queried. The type of object searched for is controlled usingSI_KINDin the query and theCeKindobject. The following code taken fromdocNav. jspshows how to retrieve the top folder in the document file structure. Example:Retrieve the top folder in a file structure. IInfoStoreiInf = (IInfoStore;)"erotSofnIssoi)este("ributAttn.ge ... String SI_NAME, SI_PARENTsQuery = "SELECT S _ , I ID ID FROM  _ ( I_ID + CI INFOOBJECTS WHERE S = " + iID + ") AND SI KIND=\'" _ +F.LOEDRCeKind + "\' ORDER BY SI_NAME ASC "; ... IInfoObjectsparentFolders = (IInfoObjects) iInf.query(sQuery); Note:In these tutorials, theISessionMgr,IInfoStore,ReportEngineandUserInfoobjects are created when the use logs in (login.jsp) and I stored in the users jsp session attributes for later use. These objects are retrieved when necessary using session.getAttribute(attributeName). By querying on theSI_ID, for a specified kind (dniKeCREDLOF.) only the top or root folder is returned. To query for a list of sub folders,SI_PARENTIDis used in the query. The result of this query is used to create the navigation mechanism. The following code shows the navigation functionality in docNav.jsp. Example:The navigation functionality in docNav.jsp. sQuery = "SELECT SI_ID, SI_NAME, SI_PARENTID FROM  + CI_INFOOBJECTS WHERE ( SI_PARENTID = " + iID + ") AND SI_KIND =\'" +REDLOFind.CeK + "\' ORDER BY SI NAME ASC "; _ IInfoObjectssubFolders = (IInfoObjects) iInf.query(sQuery); intiSize = subFolders.size(); ... for(inti=0; i<iSize; i++) { IFolderiFld = (IFolder)i;eg(tub)ss.erldFo ... <% <A HREF="docNav.jsp?sID=<%=iFld.getID()%>"

Listing Web Intelligence documents in a folder To retrieve and work with a list of Web Intelligence documents in a folder is essentially the same as retrieving and working with a list of sub folders. What changes is theCeKindused in the query. The following code taken from docNav.jspshows how to retrieve a list of Web Intelligence documents. Example:How to retrieve a list of Web Intelligence documents. sQuery = "SELECT SI_ID, SI_NAME, SI_PARENTID " + "FROM _ WHER ( _ TID = " CI INFOOBJECTS E SI PAREN + iID + ") AND SI_KIND =\'" CeKind.WEBI + _ ASC";  \ ORDER BY SI NAME + " ' IInfoObjectswebiDocuments = (IInfoObjects) iInf.query(sQuery); intwSize = webiDocuments.size(); ... for(intj=0; j<wSize; j++) { IInfoObjectiObj = (IInfoObject)webiDocuments.get(j); ... }

Searching for and listing universes is done in theunvNav.jspfile. The method used to navigate through folders and list universes is the same as that used to navigate through folders and list Web Intelligence documents. The differences are: You select objects fromCI APPOBJECTSto navigate to and list universes. _ To navigate and list documents,IInfoObjectsare retrieved from CI INFOOBJECTS. _ The Root folder ID for Universes is 95
<%=iFld.getID()%></A> %> ... }
Note:Web Intelligence documents are represented by an IInfoObject in the CMS, their is no specialized object such asIFolderused for folders. Searching for and listing universes in the CMS
