我使用本教程中的代碼片段來連接到MSSQL darabase。無法連接到MSSQL數據庫2012
http://www.java-tips.org/other-api-tips/jdbc/how-to-connect-microsoft-sql-server-using-jdbc.html
但是當我運行該程序,我得到這個錯誤。

我的連接網址是
db.dbConnect(
"jdbc:jtds:sqlserver://CSLK-PT12DB:1434/R8_JBOSS_MSSQL_Archived_Migrated_Beta","spider3","spider3");
}
究竟是什麼例外,如何解決它的原因是什麼?
錯誤消息表明在遠程主機上沒有進程偵聽。你能否驗證是否有進程正在偵聽,例如通過在遠程主機上執行'netstat -an'並查看端口1434是否實際打開? – mthmulders
yeap。在結果列表中沒有該端口的本地或外部地址。我通過找到正確的端口進行連接,您可以將它作爲答案發布.. :) – lakshman
