jsp連sql數據庫
環境設置：jdbc驅動程序
1.msbase.jar,mssqlserver.jar,msutil.jar複製到tomcat目錄/common/lib/
2.設置環境變量classpath
數據庫環境
sql-server2000(sp4補丁)
服務器環境
tomcat5.0虛擬服務器設置
1.編輯tomcat目錄/conf/server.xml,添加
<Context path="/friends" reloadable="true" docBase="E:/eclipse/workspace/friends" workDir="E:/eclipse/workspace/friends/work"></Context>
path:虛擬服務器名
docBase:物理路徑
workDir:工作目錄
reloadable="true"默認
2.啓動tomcat服務
編寫jsp文件
