show blob (images like jpg /gif) on jasper report

[rbojja]

HI,

I need to show a image on the reports.The image can be a jpg or a gif one.

The image is saved into the database as a BLOB.

 

please help me.

 

thanks

You should declare a report field of type java.awt.Image that corresponds to the DB blob column, and use the field value as image expression:

<field name="BlobColumnName" type="java.awt.Image"/><image>  <imageExpression class="java.awt.Image">$F{BlobColumnName}</imageExpression></image>

HTH,

Lucian

Thank you Lucian,

can you give a sample demo file for reference.i didnt find any in jasper reports demo files.

I created a textfield.For this i didnt find any text field expression class of type "java.awt.Image".

 

I am using iReport tool of 2.0.5 version.

 

can you correct me if i am going wrong.

I'm afraid I don't have a full sample that illustrates images from blob columns.

I don't understand why you are talking about text fields.  You need to create an image element in order to display an image, text fields are for texts.  Once you create an image element, go to Properties/Image, and set the image expression and class as shown in the attached screenshot.
