我是一名开发人员 Opentext，我需要知道如何从应用程序 Java 的内容服务器 Opentext 下载文件。我有这个代码：

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

在哪里：

  1. Content是Opentext的ContentService服务的一个实例（les-services/services/ContentService）。
  2. PATHFILE+NAMEFILE 是文件的名称和名称。
  3. _id_code_document 是文档 ID。

当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？

我猜你只是想保存文件，你可以使用这个：

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);

之前已经回答过这个问题：如何使用 Java 从 Internet 下载和保存文件？

您得到的错误是由 opentext 提供的代码示例生成的。确保 contentserviceclient 正在使用 contentserviceclient.otauthentication，因为在提供的代码中他们正在使用 documentmanagementclient.otauthentication，我对其进行了修改并且代码运行良好:)
