Hello!

I want to read the content of a file into a dynamic text.
Birt is running as a application, the file is in the local computer.

An image can be insert with the "file:///c:/test/test.jpg" as URI. I put a
function, that returs the URI in the Expression Builder.

The same thing with the dymanic text (put the URI in the Expression
Builder), I get the filename instead of the file content (I think, this is
okay), but when I try to open the file and read it with JavaScript, I get
an empty string.

Peter,

On a dynamic text onCreate event you can do something like:
importPackage(Packages.java.io);
fr = new FileReader( "c:/xfer/mydt.txt" );
inf = new BufferedReader( fr );
mydata = inf.readLine();
fr.close();
inf.close();
this.text = mydata;

This solution works with a absolute path.
I tried to write only the name of the txt file and it doesn't work.
How can I solve to this using a relative path??

Thanks
