玻璃魚3連接拒絕 - Netbeans IDE 8

Question

我想連接到glassfish服務器，但每次運行預寫入的程序時，都會出現此錯誤。我已經正確地安裝了netbeans和glassfish 3，並且已經建立了服務器，所以我沒有想法。錯誤在下面。非常感謝！

這可能是您的連接端口被佔用的問題。嘗試更改連接端口號並重新連接。找到個在目錄\與GlassFish 3.0 \ GlassFish的\域\ DOMAIN1 \ config並更改端口號8080的任何其他像9999在下面一行domain.xml文件 -

<network-listener name="http-listener-1" port="8080" thread-pool="http-thread-pool" transport="tcp" protocol="http-listener-1"/> 

關閉該文件並重新啓動了GlassFish服務器並重新運行您的程序。
