各位高手你們好
我是新來的, 遇到一個問題我解不了, 我也google過也試過一些方法, 但是都沒用, 還麻煩各位高手給我指點, 先謝謝各位高手了
我的問題是這樣的:
我寫了一支和機械設備通訊的程式, 這個程式是透過socket將XML格式的資料傳出去並接收機器的資料, 但是很奇怪的是我用我的原始程式和機器做通訊時是正常的, 但是我把程式打包成JAR後(我用的IDE是Eclipse)程式會卡在丟資料和接收資料的程式碼, 但是console卻沒秀出任何錯誤訊息, 我本來以為是ManiFest的問題, 但是改了好多版本都不行, 我將JAR檔附上, 裡面有我編寫的MANIFEST檔再幫我看看可以嗎?
以下是我處理資料的程式碼:
