Question

我有2个数据库，一个包含XPages（移动Web应用程序，让我们称之为数据库A），另一个包含文档（数据库b）。在我的测试单元中，一切正常。当我访问移动Web应用程序时，它可以完美地访问数据库B中的数据。但是当我在客户端的服务器中安装它们时，Web应用程序无法访问数据库b。我检查了所有ACL条目，我认为没关系。页面上的错误：

Error while executing JavaScript computed expression
Script interpreter error, line=161, col=18: 'ecrDB' is null
   at [/sjs_common.jss].getCRViewDetails()

导致错误的脚本是：

function getCRViewDetails(){
 158:   
 159:   var ecrDB:NotesDatabase = ECR().mainDB;
 160:   var viewDetails:Array = new Array();
 161:   if(ecrDB.isOpen()){   //----- HERE IS THE ERROR LINE!
 162:       //var vw:NotesView = ecrDB.getView("Drafts");
 163:       var vw:NotesView = ecrDB.getView(mainConstants.VIEW_MAIN);
 164:       var docs:NotesDocumentCollection = vw.getAllDocumentsByKey(session.getEffectiveUserName(), true)    
 165:       //var doc:NotesDocument = vw.getFirstDocument();
 166:       var doc:NotesDocument = docs.getFirstDocument();
 167:       while(doc != null){
 168:           viewDetails.push([
 169:               doc.getItemValueString("ProjectTitle"),
 170:               doc.getItemValueString("CRNumber"),
 171:               doc.getUniversalID()
 172:           ]);
 173:           //print(doc.getItemValueString("ProjectTitle") + ">>" + doc.getItemValueString("CRNumber"));
 174:           //doc = vw.getNextDocument(doc);
 175:           doc = docs.getNextDocument(doc);
 176:       }   
 177:   }

这是我访问数据库b（ECRDB）的方式：

function ECR(){
  34:   
  35:   //private properties and methods ---------------------------------
  36:   
  37:   //Setup document
  38:   var SetupDoc:NotesDocument = database.getProfileDocument("(Setup)","");
  39:   
  40:   // try to connect to Main DB if the sessionScope.ECRMainDBPath has been set
  41:   if(sessionScope.containsKey("ECRMainDBPath") && sessionScope.containsKey("ECRDataRepPath")){
  42:       try{
  43:           var ECRDB:NotesDatabase = session.getDatabase(
  44:               SetupDoc.getItemValueString("ECRMainServer"),
  45:               sessionScope.get("ECRMainDBPath"),
  46:               false);
  47:           var DataRep:DataRepository = new DataRepository(
  48:                   session.getDatabase(SetupDoc.getItemValueString("ECRMainServer"),
  49:                   sessionScope.get("ECRDataRepPath"),
  50:                   false));
  51:           
  52:           var ecrSettingsDoc:NotesDocument = ECRDB.getProfileDocument("eCRSettings","");
  53:       }catch(e){
  54:           print(e.message);
  55:           print("Error: Cannot access eCR Main. Please check if Anonymous is at least Reader Access");
  56:           ECRDB = null;
  57:       }
  58:   }else{
  59:       //TODO put this in init()
  60:       if(!(view.getPageName().equals("/login.xsp") || view.getPageName().equals("/selectDivision.xsp"))){
  61:           context.redirectToPage("selectDivision.xsp");
  62:       }
  63:   }
  64:   
  65:   return {
  66:       test : "Hello Orga!",
  67:       
  68:       setupDoc : SetupDoc, //get Setup Document
  69:       
  70:       getSetupValue : function(fieldName){
  71:           return this.setupDoc.getItemValueString(fieldName);
  72:       },
  73:       
  74:       //get ECR Main database (content database)
  75:       mainDB : ECRDB, 
  76:       
  77:       //get eCRSettings doc from the Main DB
  78:       mainSettings : ecrSettingsDoc, 
  79:       
  80:       //get full database path (with server)
  81:       getFullDBPath : function(){
  82:           return this.mainDB.getServer() + "!!" + this.mainDB.getFilePath();
  83:       },
  84:       
  85:       //get Data Repositoy Object
  86:       getDataRep : function(){ return DataRep; },
  87:       
  88:       //get Data Repository  //TODO remove this
  89:       //dataRep : DataRep.getDatabase(),
  90:       
  91:       //get URL for Data Repository
  92:       //getDataRepURLPath : DataRep.getURLPath,
  93:       
  94:       getDBURL : function(){
  95:           return context.getUrl().toString().split(view.getPageName())[0];
  96:       },
  97:       
  98:       getSplittedOrder : function(){
  99:           return this.mainSettings.getItemValueString("SplittedOrder");
 100:       }
 101:   };
 102: }// end of ECR declaration

我不知道数据库可能存在的问题是什么。你能告诉我为了成功访问数据库b需要检查哪些因素？非常感谢你！：）

只有当此陈述为真时，您的ECRDB变量才会初始化：

sessionScope.containsKey("ECRMainDBPath") && sessionScope.containsKey("ECRDataRepPath")

在调用ECR（）函数之前，请仔细检查sessionScope变量。

XPages无法访问数据库
