Question

我正在使用JDeveloper。在ADF Fusion Web应用程序中，我有一个输入文件控件和一个发送按钮，它调用bean方法将文件上传到UCM。如果我的文件位于我的机器上，让我们说“/home/user/myfile.txt”，它就像一个魅力。如果我尝试使用输入文件，我没有看到如何将文件上传到UCM，而不先将此文件保存到磁盘，然后上传此文件。在我看来，不推荐这种做事方式。

以下是我到目前为止能够上传来自服务器工作站的文件的代码：

// RETRIEVE THE DESTINATION PATH
DataBinder binder = idcClient.createBinder();
binder.putLocal("IdcService", "COLLECTION_INFO");
binder.putLocal("hasCollectionPath", "true");
binder.putLocal("dCollectionPath", "/Contribution Folders/PDD"); // The path you are looking for
DataBinder searchFolder = idcClient.sendRequest(idcContext, binder).getResponseAsBinder();

binder = idcClient.createBinder();
binder.putLocal ("IdcService", "CHECKIN_NEW");
binder.putLocal ("dDocAuthor", "weblogic");
binder.putLocal ("dDocTitle", "myimage2.jpg");
binder.putLocal ("dDocName", "myimage2.jpg");
binder.putLocal ("dDocType", "Document");
binder.putLocal("xCollectionID", searchFolder.getLocal("dCollectionID"));
binder.putLocal ("dSecurityGroup", "Public");
binder.putLocal ("dDocAccount:", "");
binder.putLocal ("xComments", "My comment");
binder.addFile ("primaryFile", new File("/home/oracle/myimage.jpg"));

// check in the file
ServiceResponse response = idcClient.sendRequest (idcContext, binder);

如果您有任何建议，我会非常感激。谢谢你们！

以下是解决方案：

        UploadedFile uf = (UploadedFile) inputFile1.getValue();

        DataBinder binder = idcClient.createBinder();
        binder.putLocal ("IdcService", "CHECKIN_NEW");
        binder.putLocal ("dDocAuthor", "weblogic"); // if user is admin, can specify other user
        binder.putLocal ("dDocTitle", uf.getFilename());
        binder.putLocal ("dDocName", uf.getFilename());
        binder.putLocal ("dDocType", "DigitalMedia");
        binder.putLocal("xCollectionID", getFolderCollectionId("/Contribution Folders/PDD")); // parent's folder
        binder.putLocal ("dSecurityGroup", "Public");
        binder.putLocal ("dDocAccount:", "");
        binder.putLocal ("xComments", "Montreal comment");
        binder.putLocal ("xWCTags", "Montreal");

        binder.addFile ("primaryFile", new TransferFile(uf.getInputStream(), uf.getFilename(), getByteLenght(uf.getInputStream())));

        ServiceResponse response = idcClient.sendRequest (idcContext, binder);

您已经找到了解决方案，所以我只想提一下，这里应该使用其他方便的UploadFile方法。

getFilename(); //you've got this
getLength(); //instead of getting byte length from stream
getContentType(); //available MIME

您的getFolderCollectionId("/Contribution Folders/PDD"))是否按预期工作？

另请注意，文件只有在大小小于100KB时才会存储在内存中，如果更多则写入磁盘。每个请求限制为2000KB。这些是默认值，可以在servlet上下文初始化参数中更改。

<context-param>
    <!-- Maximum memory per request (in bytes) -->
    <param-name>oracle.adf.view.faces.UPLOAD_MAX_MEMORY</param-name>
    <param-value>512000</param-value>
</context-param>
<context-param>
    <!-- Maximum disk space per request (in bytes) -->
    <param-name>oracle.adf.view.faces.UPLOAD_MAX_DISK_SPACE</param-name>
    <param-value>5120000</param-value>
</context-param>
<context-param>
    <!-- directory to store temporary files -->
    <param-name>oracle.adf.view.faces.UPLOAD_TEMP_DIR</param-name>
    <param-value>/tmp/ADFUploads/</param-value>
</context-param>

<!-- This filter is always required by ADF;  one of its functions is file upload. -->
<filter>
    <filter-name>adfFaces</filter-name>
    <filter-class>oracle.adf.view.faces.webapp.AdfFacesFilter</filter-class>
</filter>

使用RIDC将带有ADF输入文件的文件上载到UCM文件夹
