Apache POI docx - after modified the target docx file, file corrupt

I had write a code by using Apache POI 3.6.
The code is use to insert paragraph ,table and image to one docx file, but as the paragraph, table and image is from different docx file, so I need to read content from different docx file then insert to the target file.
But I found the file is only readable at the first content insert, so is there any thing need to be changed?
My method defined like following:
public class DocDomGroupUtilImpl implements DocDomGroupUtil {
private FileInputStream fips;
private XWPFDocument document;
private FileOutputStream fops;
#Override
public void generateDomGroupFile(File templateFile, List<Item> items) {
// initial parameters
Map<String, String> parameters = new HashMap<String, String>();
for (Item item : items) {
parameters.put(item.getParaName(), item.getParaValue());
}
// get domGroup type
String templateFileName = templateFile.getName();
String type = templateFileName.substring(0, templateFileName.indexOf("."));
try {
fips = new FileInputStream(templateFile);
document = new XWPFDocument(fips);
// create tempt file for document domGroup, named like
// docDomGroup_<type>_<domName>.docx
String domGroupFilePath = CONSTAINTS.temptDomGroupPath + "docDomGroup_" + type + "_"
+ parameters.get("$DomGroupName_Value") + ".docx";
File domGroupFile = new File(domGroupFilePath);
if (domGroupFile.exists()) {
domGroupFile.delete();
}
domGroupFile.createNewFile();
fops = new FileOutputStream(domGroupFile, true);
// modified the groupName
// replace content
String regularExpression = "\\$(.*)_Value";
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs) {
List<XWPFRun> runs = paragraph.getRuns();
if (runs != null) {
for (XWPFRun run : runs) {
String text = run.getText(0);
if (text != null && Pattern.matches(regularExpression, text)) {
text = parameters.get(text);
run.setText(text, 0);
}
}
}
}
document.write(fops);
close();
// copy all the information from dom related files
File dir = new File(CONSTAINTS.temptDomPath);
for (File file : dir.listFiles()) {
if (!file.isDirectory()) {
fops = new FileOutputStream(domGroupFile, true);
fips = new FileInputStream(file);
document = new XWPFDocument(fips);
document.write(fops);
}
close();
}
// clean up tempt dom folder removeAllDomFile();
removeAllDomFile();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
close();
}
}
/**
* remove all the generated tempt dom files
*/
private void removeAllDomFile() {
// loop directory and delete tempt file
File dir = new File(CONSTAINTS.temptDomPath);
for (File file : dir.listFiles())
if (!file.isDirectory()) {

}

How to build a zip file with a size of 400 GB in java

I need to download all the documents from an alfresco site that contains 400GB of documents.
The code below is ok for create a small zip file (about 1GB) otherwise it takes too much memory.
I would not like to keep ZipOutputStream in memory, i would like to use memory only for every document copied to the Zip file or use a temporary file that is overwritten for each document.
What is the best practice for this kind of problem?
This piece of code is called from my main:
FolderImpl sitoFolder = (FolderImpl) cmisObject;
List<Tree<FileableCmisObject>> sitoFolderDescendants = sitoFolder.getDescendants(-1);
byte[] zipFile = createZipFILE(sitoFolderDescendants);
String rootPath = cartella_download_file;
File dir = new File(rootPath + File.separator);
if (!dir.exists()) {
dir.mkdirs();
}
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String stringDate = sdf.format(date);
String nameZipFile = sitoFolder.getName().replaceAll("\\s","");
File serverFile = new File(dir.getAbsolutePath() + File.separator + stringDate+"_"+nameZipFile+".zip");
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(new FileOutputStream(serverFile));
IOUtils.write(zipFile, bufferedOutputStream);
bufferedOutputStream.close();
//Returns the zip file
private byte[] createZipFILE(List<Tree<FileableCmisObject>> list) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ByteTransform byteTransform = new ByteTransform();
try {
ReportDocument reportDocument = new ReportDocument();
ZipOutputStream zos = new ZipOutputStream(baos);
for (Tree<FileableCmisObject> aList : list) {
traverseTree(aList, zos, reportDocument);
}
zos.close();
return baos.toByteArray();
} catch (IOException exc) {
reportLog.error(exc.getMessage());
} finally {
baos.close();
}
return new byte[0];
}
private void traverseTree(Tree<FileableCmisObject> tree, ZipOutputStream zos, ReportDocument reportDocument) {
for (int i=0; i<tree.getChildren().size(); i++) {
Tree<FileableCmisObject> child = tree.getChildren().get(i);
if (CmisUtil.isDocument(child.getItem())) {
Document document = (Document) child.getItem();
try {
addToZipFile(document, zos);
} catch (IOException ioExc) {
appLog.error(ioExc.getMessage());
}
} else if(CmisUtil.isFolder(child.getItem())) {
Folder folder = (Folder) child.getItem();
if (folder.getChildren().getTotalNumItems() == 0) {
try {
addToZipFolder(folder, zos);
} catch (IOException ioExc) {
appLog.error(ioExc.getMessage());
}
}
}
traverseTree(child, zos, reportDocument);
}
}
//Service method to add documents to the zip file
private void addToZipFile(Document document, ZipOutputStream zos) throws IOException {
InputStream inputStream = document.getContentStream().getStream();
String path = document.getPaths().get(0).replace(sito_export_path, "");
ZipEntry zipEntry = new ZipEntry(path);
zos.putNextEntry(zipEntry);
IOUtils.copy(inputStream, zos, 1024);
inputStream.close();
zos.closeEntry();
}
//Service method to add empty folder to the zip file
private void addToZipFolder(Folder folder, ZipOutputStream zos) throws IOException {
String path = folder.getPaths().get(0).replace(sito_export_path, "");
ZipEntry zipEntry = new ZipEntry(path.concat("/"));
zos.putNextEntry(zipEntry);
}

I solved it. I first created a directory on the server and then created the zip file on this directory directly.
The error was to save all the files first on: ByteArrayOutputStream and then on the zip file.
File serverFile = new File(dir.getAbsolutePath() + File.separator + stringDate+"_"+nameZipFile+".zip");
FileOutputStream fileOutputStream = new FileOutputStream(serverFile);
ZipArchiveOutputStream zos = new ZipArchiveOutputStream(fileOutputStream);
for (Tree<FileableCmisObject> aList : sitoFolderDescendants) {
traverseTree(aList, zos, reportDocument);
}
zos.close();
In the finally block I close the FileOutputStream.
Than I changed the services method using: ZipArchiveOutputStream and ZipArchiveEntry.
private void addToZipFolder(Folder folder, ZipArchiveOutputStream zos) throws IOException {
String path = folder.getPaths().get(0).replace(sito_export_path, "");
ZipArchiveEntry zipEntry = new ZipArchiveEntry(path.concat("/"));
appLog.info("aggiungo cartella vuota "+folder.getName()+" al file zip");
zos.putArchiveEntry(zipEntry);
zos.closeArchiveEntry();
}
private void addToZipFile(Document document, ZipArchiveOutputStream zos) throws IOException {
InputStream inputStream = document.getContentStream().getStream();
String path = document.getPaths().get(0).replace(sito_export_path, "");
ZipArchiveEntry entry = new ZipArchiveEntry(path);
entry.setSize(document.getContentStreamLength());
zos.putArchiveEntry(entry);
byte buffer[] = new byte[1024];
while (true) {
int nRead = inputStream.read(buffer, 0, buffer.length);
if (nRead <= 0) {
break;
}
zos.write(buffer, 0, nRead);
}
inputStream.close();
zos.closeArchiveEntry();
}

TessAPI Error during processing. in Spring Mvc and tomcat 7

PRJ file not generated for null CoordinateReferenceSystem

I am trying to create a shape file from the the text file. To do this I used Geotools library.
It can create the shapefile, but I got a warning about the coordinate system that is null, which I'm setting!
The data are in UTM-wgs84-Zone 30N. First, I tried default Coordinate System (WGS84), then I used EPSG and decoded it. It returns null.
