Need to Create an image from XML Source.

Hi,
I need to create an image on report from XML data Source.

My Steps are :-
1)Create an xml file with image tag where it contains the image byte data.
2)Created the DataSource for this XML
3)Created Data Set:- have one coloumn named as "image".

So I have created Java script Events :-

1)Before Factory :- here we can add the Dynamic elements to the report.But we can't access row["image"].
2)For Data Set onFetch():-retrieving the row["image"] and placing in report context parameter.
3)Created one Static image for OnCreate():- getting the Image Byte code from report context Parameter and creating the file,adding to it as follows.

importPackage( Packages.java.io );
fos = new java.io.FileOutputStream( "E:logFile123456.jpg" );
printWriter = new java.io.PrintWriter( fos );
var myimage=reportContext.getParameterValue("imagedata");
for(var count=0;count< myimage.length();count++)
{
printWriter.println(myimage[count]);

}

File is created successfully,getting Exception as Unhandled Exception.
Could anyone please help me to build this report.

Thanks and Regards
Swetha.

Can you post the xml file that contains the image?

The wrong one of the two duplicate threads got removed. Here's the attachment from the other one.

This foto.xml does not look like blob data for an image. It is just the same character sequence repeated. Is this a real image?

It appears it is just the same byte array address for each one. How did you create the field. It may be better to base64encode the byte array and write that to your xml tag. You should then be able to write some script in the on create of the image to decode and set the bytes.

Hi Jason,
Thanks for Reply.I am trying to encode and decode the image with Java Application.Once I Complete this i can provide the xml file with encoded byte data of Image.
So You'r saying that if we place the decoding byte Array at the "OnCreate "Event of image,It should be display on report.
this.data=byte Array.

Is i m correct or plz correct me...........

Thanks and Regards
