如何將連接從我的java swing應用程序傳遞到Crystal Reports XI？

Question

我有這樣的代碼，我在我的揮杆應用程序中使用：

ReportClientDocument rpt = new ReportClientDocument(); 
    rpt.open(reportPath+"APVendorList.rpt", 0); 
    rpt.getReportSource(); 


    ReportViewerBean viewer = new ReportViewerBean(); 
    viewer.init(new String[0], null, null, null); 
    //viewer.setHasGroupTree(false); 
    viewer.setReportSource(rpt.getReportSource()); 

的問題是，每當我嘗試使用JFrame的加載報告，它總是要求登錄憑據：

Database Logon: 
Server Name: Localhost 
Database Name: <blank and cannot be edited> 
User ID: 
Password: 

是有沒有辦法不輸入這些信息eveytime我查看報告？或者我可以只傳遞java.sql.Connection到它？此外，它似乎不知道要連接到哪個數據庫。請幫忙。

您可以設置的屬性值，像這樣：

ReportClientDocument clientDoc = new ReportClientDocument(); 
.... 
DatabaseController dbController=clientDoc.getDatabaseController(); 
IConnectionInfo ConnInfo = dbController.getConnectionInfos(null).getConnectionInfo(0); 
com.crystaldecisions.sdk.occa.report.lib.PropertyBag boPropertyBag1 = new com.crystaldecisions.sdk.occa.report.lib.PropertyBag(); 
// Set the properties for the connection 
boPropertyBag1.put("JDBC Connection String", connString); 
boPropertyBag1.put("Database Class Name", dbClassName); 
boPropertyBag1.put("Connection URL", connString); 
boPropertyBag1.put("Server", serverHost); 
.... 
// Assign the properties to the connection info 
ConnInfo.setAttributes(boPropertyBag1); 
// Set the DB Username and Pwd 
ConnInfo.setUserName(usrName); 
ConnInfo.setPassword(pwd); 

希望這有助於...
