這裏是standalone.xml配置...

請這將是對這一問題的原因建議。

我在其他環境中獲得了相同配置的成功。我不知道我現在爲什麼會遇到這個問題。主機， - dev-scan.dev.com和端口1521可以被JBoss應用服務器系統訪問。

Answer 1

我觀察telnet到端口1521 ................

防火牆或一些其它配置。使得連接會後Escape character is '^]'.

連接關閉一個即時的基礎上，

我希望這應引起問題.....

$telnet dev-scan.dev.com 1521 
Trying 10.252.103.108... 
Connected to cmdbdev-scan.dev.com. 
Escape character is '^]'. 
Connection closed by foreign host. 

問題是socket-connection-close立即發生由外國主機關閉。

Answer 2

我也面臨同樣的問題，我發現我的連接url是worng，由於它不能連接到數據庫。檢查連接網址，用戶名和密碼。
