Java – get the POI Workbook of InputStream for OM Apache

Is there any way to get the InputStream of Apache POI workbook?

I need it to pipe to another OutputStream, but I can't find such a method (if it exists)

If not, any tips on alternative ways to get it?

Solution

There are several ways to solve this problem:

>You can use standard Java pipetinputstream and pipedoutputstream However, you must create different threads for using pipedinputstream (such as http://docs.oracle.com/javase/7/docs/api/java/io/PipedInputStream.html You can write content to bytearrayoutputstream, and then you can use the resulting byte array through bytearrayinputstream This can be done sequentially in one thread
