We have a Java process (see below) to generate DOC, DOCX, XLS, XLSX, and HTML and save it to our Linux PCs. It ran well in our old AIX 3.5 machine; but in our new RHEL 7.5 machine, Microsoft proprietary document formats (DOCX, DOC, XLSX, and XLS) it outputs are corrupt. HTML files are not corrupt.



I have downloaded the output files into a Windows PC and try to open them; Exception errors say the DOC/DOCX/XLS/XSLX files are corrupt and cannot be opened.



The Java code works well in the old Linux PC. I am assuming there might some libraries or software we need to install in the new PC.



Below is my java code (Process to generate the file)



int BUFFER_SIZE=1024*256;



 int bytesRead=0;
Resultset rs=obj.resultSet();
DocumentClass = new DocumentClass();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buffer = new byte[BUFFER_SIZE];
BufferedInputStream bis = new BufferedInputStream(rs.getBinaryStream(1));

try

bytesRead = bis.read(buffer,0,BUFFER_SIZE);
while (bytesRead > 0)

baos.write(buffer, 0, bytesRead);
buffer = new byte[BUFFER_SIZE];
bytesRead = bis.read(buffer,0,BUFFER_SIZE);


catch (IOException io )

System.out.println(io.getMessage());


DocumentClass.setFileBody(baos);
BufferedWriter CreateDoc = new BufferedWriter(new FileWriter("/usr/Test.docx"));
CreateDoc.write(DocumentClass.getFileBody().toString());
CreateDoc.close();

    Are you using the same java version? Maybe you are running a newer java version on RHEL that is not supported? Are the jars/.class files in the classpath the same? Do you have no logfile? What framework/library are you using (CreateDoc)?
