How to show binary content as file in pega
We are using filenet to store our attachments. But user want to see some times that attachments as native documents. So we have queried the filenet system and got the binary content. But how to show this binary content to users as file.

As a working example of streaming a binary file back to the browers: take a look at the OOTB Activity 'Code-Pega-PDF.View'; I have included the Java Step Code below for convenience:
//Get the byte array from the parameter page
byte[] byteArray=(byte[])tools.getParameterPage().getParameterValue("PDFDocument");//Get the pdf name from the parameter page
String pdfName=tools.getParamValue("PDFName");//Send the PDF File back to the user.
String result=tools.sendFile(byteArray,pdfName,false,null,true);

Hi Devaraju,
I have never tried this, but on research I have found few interesting things from other Pega developers.
In an activity, add a Java Step to write the binary stream content to a file. Once file becomes available, then you can invoke DownloadFile OOTB activity to download this file for user. You can configure these things on a button with a call to invoke an activity.
Hope it helps you.
FileName = new java.io.File(FullPath+pdfName);
fileOuputStream = new java.io.FileOutputStream(FileName);
fileOuputStream.write(byteArray);
fileOuputStream.close();
Then you can call OOTB "DownloadFile" activity and pass the required parameters.

Not sure, how much it would help but it may help in understanding image content data instances.
It has three part, on the left side panel you can find other two as well.
Usage of Show-Stream method :- https://community.pega.com/sites/default/files/help_v722/procomhelpmain.htm
Kindly notify, if it helps.
