How to hide an image if the path does not exist.

Hello.

I have to display an image from the shared resorces ( I give its path). If the image exists, everything looks fine, but if not, there appears a text with the "image not reachable" message in the generated report(see atachment)

Is the image in the resource folder or is the path a full url. If it is in the resource folder you could try something like reportContext.getResource("imagename"); Then check this value for null. If the image is a url you could try something like:

valid_url=true;
importPackage(Packages.java.net);
try {
url = new URL("urltoimage");
input = url.openStream();
input.close();
} catch (e) {
valid_url = false;
}

Hi Janson , iam using URI , but your code for visibility is not working

Hi,
 
I got the code working, but you may want to consider a couple of things:
 
1. If you are running your report from BIRT Designer, make sure the URL (specifically the image filename) does not contain spaces. There is an issue with Tomcat where creating a URL with a space. So, you need to replace spaces with the proper encoding, %20.
 
2. The code does not run when scripted in the image component. In the attached example, I have added the code to the report's beforeFactory. The result is saved in a global variable. I test the value of that variable in the image Visibility property.
 
Hope this helps,
 
P.
