java 鏈接sql server 2000 總結(jié)

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

執(zhí)行后總是出現(xiàn)：

跟著程序走了以下，確實(shí)沒有這個(gè)方法，郁悶了一天

經(jīng)過反復(fù)調(diào)試后發(fā)現(xiàn)有幾種可能造成這個(gè)原因

1.驅(qū)動(dòng)程序的版本不對(duì)

2 .sql server 2000沒有打補(bǔ)丁必須打補(bǔ)丁

3 .檢查sql server 2000 的驅(qū)動(dòng)程序mssql.jar，msbase.jar，mssqlserver.jar，msutil.jar存放位置對(duì)不對(duì)，一般放在tomact/commen/lib下就可以,或放進(jìn)class_path，或webinfo/lib下，一般情況下，放一個(gè)地方就可以了

4 .位置方對(duì)了還不行那可以考慮jdbc驅(qū)動(dòng)程序的版本對(duì)不對(duì)，如果你打了 sp2補(bǔ)丁那么也要用for sp2 driver

到此，相信大家對(duì)“java鏈接sql server 2000后出錯(cuò)的原因”有了更深的了解，不妨來實(shí)際操作一番吧！這里是創(chuàng)新互聯(lián)網(wǎng)站，更多相關(guān)內(nèi)容可以進(jìn)入相關(guān)頻道進(jìn)行查詢，關(guān)注我們，繼續(xù)學(xué)習(xí)！
