CommandTable cystal報告錯誤

Question

我有一個使用複雜SQL編寫的Crystal報告，我試圖使用Crystal Report Java API調用該報告。此報告具有與其關聯的Command對象。

1. 我加載報告並設置連接參數。
2. 然後我嘗試將連接信息設置爲當前的JDBC配置文件。含義測試環境證書。

我得到一個異常。我嘗試使用版本11。他們似乎都沒有工作。

我在調用下面的一段代碼時收到異常。對於沒有「Command」sqls的報告，這段代碼工作得很好。

try{ 
    clientDoc.getDatabaseController().setTableLocation(
    origTable, newTable); 
}catch(Exception ex){ 
    ex.printStackTrace(); 
} 

查看下面的完整代碼。如果有人知道如何解決這個問題，請回復。

Answer 1

加入這一行你的

connectionInfo.setPassword(DB_PASSWORD); 
newTable.setConnectionInfo(connectionInfo); 
//This will add connection parameters to the new table 

而不是

clientDoc.getDatabaseController().setTableLocation(origTable, newTable); 

後

clientDoc.getDatabaseController().setTableLocation (newTable, tables.getTable(i));
