请你最好是用jsp+servlet+javaBean的模式来做，这样做会更好。
你的问题多半是sql语句有问题（包括语法、字段属性等）。

你的错误比较难找：

if (!MM_abortEdit) {
// finish the sql and execute it
Driver MM_driver = (Driver)Class.forName(MM_editDriver).newInstance();
Connection MM_connection = DriverManager.getConnection(MM_editConnection,MM_editUserName,MM_editPassword);
out.println("Sql=="+MM_editQuery.toString()) ;//输出你的SQL语句看看，有没有问题，把它放到sql分析器中执行一下。
PreparedStatement MM_editStatement = MM_connection.prepareStatement(MM_editQuery.toString());
MM_editStatement.executeUpdate();
MM_connection.close();

如果上面语句没有输出，说明错误不在这里，可能在上面，你可能用同样的方法跟踪。

我遇到过同样的问题，原因是我提交的字符串超过了在数据库中变量定义的长度，也显示javax.servlet.ServletException: [Microsoft][ODBC SQL Server Driver][SQL Server]将截断字符串或二进制数据。
应该和你定义的变量长度或输入数据有关。

源程序对于上面的的错误，我想应该是一个原因吧，如果解决了，我会再加分的 80
