Question

我是开发人员Opentext，我需要知道如何从app Java下载内容服务器Opentext中的文件。我有这段代码：

int nodeID = _id_code_document;
OutputStream os = new FileOutputStream(new File(PATHFILE+NAMEFILE));
DataHandler file= fContent.downloadContent(nodeID + "");
file.writeTo(os);

其中：

Content是Opentext（les-services / services / ContentService）的ContentService服务的实例。
PATHFILE + NAMEFILE是文件的用途和名称。
_id_code_document是文档ID。

此代码运行时出现此错误：

任何人都知道如何解决这个问题？

Thx 4提前！

我猜你只想保存文件，你可以使用：

URL website = new URL("Path to your file on the server");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream("Path to where you want to save the file");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);

您获得的错误是从opentext提供的代码示例生成的。确保contentserviceclient正在使用contentserviceclient.otauthentication，就像他们使用documentmanagementclient.otauthentication提供的代码一样，我修改了它并且代码工作得很好：）
