error try to print an image in IREPORT 3.1

[pioppogatto]

I'm a newby.

I'm using ireport 3.1 and I'm trying to print a report composed of  one page for eache record in my tab.

The source for the report is a materialized view on oracle and it's like this

id (primary key)

name (varchar)

field_image (varchar)

 

The field_image in the materialized view as a string link this: "C:\dati\immagine_1.jpg"

 In my report the image properties are:

Expression class like: java.lang.string

Expression Image like $F{field_image}

 

When I try to print the report I get this error: Error filling print ... Byte data not found at location

 

 

 

Code:

I've solved my problem.

The field of the materialized view that stored the path string to the image must be written without double slash and without "

The wrong string was like this:   "C:\documents\image\1.jpg"

the correct one must be a simple path like this: C:documentsimage1.jpg
