IED Eclipse Java EE IDE for Web Developers:
DTD 类型约束文件
1. Window->Preferences->XML->XML Catalog->User Specified Entries窗口中,选择Add 按纽
2.在Add XML Catalog Entry 对话框中选择或输入以下内容:
Location: F:\soft\programmingSoft\Framework\Ibatis\sql-map-config-2.dtd
Key Type: URI
KEY: http://ibatis.apache.org/dtd/sql-map-config-2.dtd //在dtd中找
或者：
Location: F:\soft\programmingSoft\Framework\Ibatis\sql-map-config-2.dtd
Key Type: Public ID
KEY: -//ibatis.apache.org//DTD SQL Map Config 2.0//EN
Specify alternative web address:http://ibatis.apache.org/dtd/sql-map-config-2.dtd
注：
[如果不知道KEY，就是用本地文件sql-map-config-2.dtd放到xml的同级目录下
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"./sql-map-config-2.dtd">
]

<bookstore>
<book genre="fantasy" ISBN="2-3631-4">
