------解决方案--------------------在界面生成表单?
try {
// Create a result set
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery( "SELECT * FROM my_table where rownum <=1 ");
// Get result set meta data
ResultSetMetaData rsmd = rs.getMetaData();
int numColumns = rsmd.getColumnCount();
// Get the column names; column indices start from 1
for (int i=1; i <numColumns+1; i++) {
String columnName = rsmd.getColumnName(i);
// Get the name of the column 's table name
String tableName = rsmd.getTableName(i);
out.println( " <input type= 'text ' name= ' "+tableName+ " ' />
}
} catch (
SQLException e) {
}
------解决方案--------------------orm先生成javaBean,作为Form,根据该Form生成表单

Statement stmt_com=conn.createStatement();
//stmt_com.executeUpdate( "insert into TEST_STUDENT(id,name` ,age,sex) values( '1003 ', '小王 ', '29 ', '女 ') ");
//stmt_com.executeUpdate( "update test_student set name= '小刘 ',sex= '男 ' where name= '小王 ' ");
ResultSet rs_com=stmt_com.executeQuery( "select * from STUDENT ");
while(rs_com.next())

rs_com.close();
stmt_com.close();
conn.close();

这是我的,可以参考下。
------解决方案--------------------要和hibernate类似的效果么???
------解决方案--------------------这样是不行的,生成了表单文本筐,还有描述类,排版呢,怎么获取值提交表单返回值呢,多着呢,学着吧,告诉你用xml+xsl可以实现
