Printing PDF report from stored byte array

[samueel01]

I need print a report from a byte array that is stored on database.

I already have the byte array.

The code is the following:

 

Code:

InputStream bays = new ByteArrayInputStream(auto.getArquivo());

JasperPrint print = (JasperPrint) JRLoader.loadObject(inByteArray) ;//Error

JasperViewer viewer = new JasperViewer(print, false);

viewer.setVisible(true);

 

In the tag Error, the Exception is the following:

 

StreamCorruptedException invalid stream reader

 

Error loading object from InputStream

Hi,

 

What exactly did you put in the database?

It does not seem to be a serialized JasperPrint object as expected by the API you called.

 

I hope this helps.
