I’m designing a jasper report using iReport which takes a parameter and fetches an image from a given URL:

The parameter is a user’s screen name in twitter, and the url is it’s profile image.

    <image>
       <reportElement x="4" y="51" width="73" height="64"/>
           <imageExpression><![CDATA["https://api.twitter.com/1/users/profile_image?screen_name="+$F{user_screen_name}+"&size=bigger"]]></imageExpression>
    </image>

It works great when the image exists. If it doesn’t the following exception is thrown:

    Print not filled. Try to use an EmptyDataSource...

How can i handle this situation in the jrxml file?

I would like to simply add a fixed URL address in case it can’t find one.

Anyone has any suggestions?

Thank you!

    I think you need to add an additional helper class to handle this. You need a static method boolean urlExists(String url) that would allow you to put this in the imageExpression:

    MyClass.urlExists($F{image_url}) ? $F{image_url} : $P{fallback_image}

    It would be a simple class to write… but clearly there’s additional complexity in adding in another .jar file. Without that method, I can’t see any way to do the processing in the .jrxml.
