java 連結sql server 2000 問題

java 連結sql server 2000 總結

Context envContext = (Context)initCtx.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/jieba");
conn = ds.getConnection();

執行後總是出現：

跟著程式走了以下，確實沒有這個方法，鬱悶了一天

經過反覆除錯後發現有幾種可能造成這個原因

1.驅動程式的版本不對

2 .sql server 2000沒有打補丁 必須打補丁

3 .檢查sql server 2000 的驅動程式mssql.jar，msbase.jar，mssqlserver.jar，msutil.jar存放位置對不對，一般放在tomact/commen/lib下就可以,或放進class_path，或webinfo/lib下，一般情況下，放一個地方就可以了

4 .位置方對了還不行 那可以考慮jdbc驅動程式的版本對不對，如果你打了 sp2補丁 那麼也要用for sp2 driver
