线程“AWT-EventQueue-0”中的异常java.lang.NoSuchMethodError在Swing方法中

我得到了一个返回Vector的函数的错误。在每件事情都正常工作之前，我将Vector []的返回类型更改为Vector。线程“AWT-EventQueue-0”中的异常java.lang.NoSuchMethodError在Swing方法中

异常的堆栈跟踪如下：

代码的SSCCE是如下

import java.sql.Connection; 
    import java.sql.PreparedStatement; 
    import java.sql.ResultSet; 
    import java.sql.ResultSetMetaData; 
    import java.util.Vector; 
    import java.util.logging.Level; 
    import java.util.logging.Logger; 



    class DBUtil.DBEngine { 

     public static Vector<Object> getComboDataAllQry(String colId,String colName,String tblName) throws Exception { 

     Vector<Vector<String>> comboVector = new Vector<Vector<String>>(); 
     Vector<Object> test = new Vector<Object>(); 

     Connection conn = dbConnection(dbName); 

     ResultSet rsCombo=GetResultSetForQry(" Select"+colId+","+colName+" from "+tblName); 
     ResultSet rsAllData=GetResultSetForQry(" Select * from "+tblName); 

     Vector<String> colNames = getColumnNamesFromResultSet(rsAllData); 
     Vector<Vector<String>> comboVector = GetVctFromResultSet(rs_); 

     Vector<Vector<String>> compResultSet = GetVctFromResutSet(rsAllData; 


     test.add(comboVector); 
     test.add(compResultSet); 
     test.add(colNames); 
     return test; 
    } 
} 

    import DBUtil.DBEngine; 


    public class jewelleryerpapplication.GUI.Orders.Orders{ 
    JComboBox orders=null; 
    Vector<Vector<String> dataAll=null; 
    public static void GetComboData(){ 
    Vector<Object> obj= DBUtil.DBEngine.getComboDataAllQry("OrderID","OrderName"+"OrdersNew.dbo.Orders"); 

    Vector<Vector<String>> ComboData =(Vector<Vector<String>>)obj.get(0); 
    Vector<Vector<String>> data =(Vector<Vector<String>>)obj.get(1); 
    orders =New JComboBox(new DefaultComboBoxModel(ComboData))'

}

public void formWindowOpened(){ 
    GetComboData(); 
    } 

    public static void main(String args[]) { 
    java.awt.EventQueue.invokeLater(new Runnable() { 

      public void run() {

      } 
     }); 
    } 

    } 


}

你能发表'getComboDataAllQry（）'方法吗？ – NINCOMPOOP 2013-04-29 11:42:14

奇怪：SSCCE代表简短，独立，完整，可编辑的例子。我想你错过了5个单词中的3个。 – 2013-04-29 11:42:28

@GuillaumePolet实际上我有3个项目目录（主项目）。 2）DBUtil 3）订单（目录和订单具有DBUtil）以及getComboDataAllQry（）在DBUtil中定义。订单项目中出现此异常。我已经清理了每一件事。我已经将库添加为项目的dist文件夹的引用路径 – 2013-04-29 12:05:04

调用代码仍然可以看到老您的被调用代码的版本，它具有不返回数组的旧方法。这不是一个编程问题，它只是关于在运行/部署之前如何构建项目。建议：清理一切并从头开始重建。

其实我有3个项目目录（主要项目）。 2）DBUtil 3）订单（目录和订单具有DBUtil）以及getComboDataAllQry（）在DBUtil中定义。订单项目中出现此异常。我已经清理了每一件事。我已将库添加为项目的dist文件夹的参考路径。 – 2013-04-29 11:58:54

我已经清理了每一件东西，但仍然出现错误 – 2013-04-29 12:10:00
