ClassNotFoundException NetBeans 7.3

Question

我遇到了一些我试图通过NetBeans 7.3运行的示例代码的问题。我有理由相信它与NetBeans及其配置有关，因为我能够通过Windows 7控制台（CLI）和Eclipse运行此代码而没有任何问题。尽管我喜欢NetBeans我发现自己正在转向看似更有能力的Eclipse，如果不是因为ide代码绘画，我很乐意回到记事本，这无疑会节省大量的时间和压力。

问题是我在尝试读取第一条记录时得到ClassNotFoundException。文件本身似乎打开没有错误。

以下是涉及的问题所涉及的课程---＆gt;

import java.io.EOFException;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;

public class ReadSequentialFile
{
   private ObjectInputStream input;

   // enable user to select file to open
   public void openFile()
   {
      try // open file
      {
         input = new ObjectInputStream(
            new FileInputStream( "clients.ser" ) );
      } // end try
      catch ( IOException ioException )
      {
         System.err.println( "Error opening file." );
      } // end catch
   } // end method openFile

   // read record from file
   public void readRecords()
   {
      AccountRecordSerializable record;
      System.out.printf( "%-10s%-12s%-12s%10s\n", "Account",
         "First Name", "Last Name", "Balance" );

      try // input the values from the file
      { 
         while ( true )
         {
            record = ( AccountRecordSerializable ) input.readObject();

            // display record contents
            System.out.printf( "%-10d%-12s%-12s%10.2f\n",
               record.getAccount(), record.getFirstName(),
               record.getLastName(), record.getBalance() );
         } // end while
      } // end try
      catch ( EOFException endOfFileException )
      {
         return; // end of file was reached
      } // end catch
      catch ( ClassNotFoundException classNotFoundException )
      {
         System.err.printf( "Unable to create object. : %s\n", ClassNotFoundException.getMessage() );
      } // end catch
      catch ( IOException ioException )
      {
         System.err.println( "Error during reading from file." );
      } // end catch
   } // end method readRecords

   // close file and terminate application
   public void closeFile()
   {
      try // close file and exit
      {
         if ( input != null )
            input.close();
         System.exit( 0 );
      } // end try
      catch ( IOException ioException )
      {
         System.err.println( "Error closing file." );
         System.exit( 1 );
      } // end catch
   } // end method closeFile
} // end class ReadSequentialFile

这是NetBeans与---＆gt;

有问题的AccountRecordSerializable类

import java.io.Serializable;

public class AccountRecordSerializable implements Serializable
{
   private int account;
   private String firstName;
   private String lastName;
   private double balance;

   // no-argument constructor calls other constructor with default values
   public AccountRecordSerializable() 
   {
      this( 0, "", "", 0.0 );
   } // end no-argument AccountRecordSerializable constructor

   // four-argument constructor initializes a record
   public AccountRecordSerializable(
      int acct, String first, String last, double bal )
   {
      setAccount( acct );
      setFirstName( first );
      setLastName( last );
      setBalance( bal );
   } // end four-argument AccountRecordSerializable constructor

   // set account number   
   public void setAccount( int acct )
   {
      account = acct;
   } // end method setAccount

   // get account number   
   public int getAccount() 
   { 
      return account; 
   } // end method getAccount

   // set first name   
   public void setFirstName( String first )
   {
      firstName = first;
   } // end method setFirstName

   // get first name   
   public String getFirstName() 
   { 
      return firstName; 
   } // end method getFirstName

   // set last name   
   public void setLastName( String last )
   {
      lastName = last;
   } // end method setLastName

   // get last name   
   public String getLastName() 
   {
      return lastName; 
   } // end method getLastName

   // set balance  
   public void setBalance( double bal )
   {
      balance = bal;
   } // end method setBalance

   // get balance   
   public double getBalance() 
   { 
      return balance; 
   } // end method getBalance
} // end class AccountRecordSerializable

让这一切顺利进行的主要课程： -

public class ReadSequentialFileTest
{
   public static void main( String[] args )
   {
      ReadSequentialFile application = new ReadSequentialFile();

      application.openFile();
      application.readRecords();
      application.closeFile();
   } // end main
} // end class ReadSequentialFileTest

我已使用此链接https://netbeans.org/kb/docs/java/project-setup.html#projects-classpath上的建议更改了类路径，以显式使用可找到AccountRecordSerializable的目录。它没有任何修复。

clients.ser包含我放在项目目录根目录中的3条记录。

我讨厌留下未解决的问题，所以我希望有人可以帮助我;）
