我基本上有一個程序,使用apache poi將記錄從一個excel文件過濾到另一個excel文件。使用netbeans運行時,我的程序運行良好。但是,在執行clean and build並雙擊dist文件夾內的.jar文件時,它會運行很長時間(太長!),並給我出現以下錯誤(通過從命令提示符運行程序得到)。outofmemoryerror當運行jar時,但不在netbeans/apache poi中運行
有什麼解決辦法嗎?在清理和建設之前,我已經將netbeans內的堆大小增加爲-Xms1500m。

我如何設置它,讓我雙擊jar文件,然後它會像那樣運行它?非常感謝! – Laughy
我認爲你可以用批處理文件去。雙擊批處理文件將運行你的項目。 – Zombie
謝謝,該批處理文件與一個VBScript腳本文件結合在一起,隱藏了cmd窗口,完美地工作! – Laughy
