我正在運行時遇到問題。我在使用weblogic部署的應用程序中使用了ICEFaces罐子。當我部署戰爭並嘗試上傳戰爭時,它不起作用,我能夠捕捉到以下例外情況。但是,當我在weblogic中部署分解的war文件夾時,它不起作用。由於它正在爲爆炸戰爭文件夾工作,我覺得它無法創建一個文件夾來上傳文件。有什麼我需要配置來解決這個問題?當warlogi部署在weblogic中時fileupload不工作,但是如果部署了爆炸war文件夾,則工作
部分的的web.xml:
部分的<context-param>
<param-name>com.icesoft.faces.uploadDirectory</param-name>
<param-value>/upload</param-value>
</context-param>
JSP
<ice:inputFile
submitOnUpload="postUpload" id="inputFileComponent"
actionListener="#{uploadAction.uploadActionListener}"
action="#{uploadAction.doUploadFile}" />
其中uploadAction是具有方法uploadActionListener()作爲動作偵聽器和doUploadFile動作類作爲動作映射

昨天我嘗試了類似的方式,但沒有奏效。我給了絕對的路徑,並最終奏效。謝謝@TheCoolah – user123475
