使用FileNet Java API版本5.1.0.3
我正在尝试将大文档上传到P8。我正在使用FileInputStream读取文件并将输入流设置为contentTransfer.setCaptureSource(file);我正在获得OOM异常(完整的堆栈跟踪)。看起来它试图在堆内存中读取整个文档,但这不是我想要的,我想将文档流式传输到P8。
代码
//Get CE Connetcion
//Create Subject
//Push Subject
//Get Domain (domain)
ObjectStore os = null;
objectStoreName = "COS"
os = Factory.ObjectStore.fetchInstance(domain, objectStoreName, null);
//Get Folder
Folder folder=null;
folderName = ''/Sample";
folder=Factory.Folder.fetchInstance(os, folderName, null);
//Get the File details
InputStream file = "";
String fileName = "";
int fileSize = "";
// Create Document
String docClass = "dcumnet class name";
Document doc = Factory.Document.createInstance(os, docClass);
if (file != null && fileSize > 0) {
ContentTransfer contentTransfer = Factory.ContentTransfer.createInstance();
contentTransfer.setCaptureSource(file);
contentElementList.add(contentTransfer);
doc.set_ContentElements(contentElementList);
contentTransfer.set_RetrievalName(fileName);
doc.set_MimeType(getMimetype(fileName));
}
//Check-in the doc
doc.checkin(AutoClassify.DO_NOT_AUTO_CLASSIFY,CheckinType.MAJOR_VERSION);
//Get and put the doc properties
String documentName =""
Properties p = doc.getProperties();
p.putValue("DocumentTitle","abcd");
p.putValue("Name","Rakesh");
p.putValue("Number","01234");
doc.save(RefreshMode.REFRESH)
请帮忙,如何将更大的文档作为流发送到P8?

答案 0 :(得分:2)
WSI
传输能够传输任意大小的内容。它使用MTOM
个附件,这些附件在HTTP
上流式传输。目前尚不清楚为什么会尝试在您的情况下分配一个巨大的缓冲区。流式传输也需要一些缓冲,但不需要大缓冲区。
假设您正在使用java.io.FileInputStream
并且没什么特别的,它看起来像Content Engine
客户端库中的错误。您应该注意版本5.1.0.3
超过4年,从那时起有几个修订包(最近一个是5.1.0.7
)。
