Hi mariane,

You can read in a text file in javascript, using the java.io package. Then store the text in a global variable that you can then use to display the text anywhere.

Hope this helps.

hi,
thanks for help
this is just what i try to do but i doesn't found a relation between my class java and the method onprepare of my eventhandler.
this my java class:

import java.io.*;

import org.eclipse.birt.report.engine.api.script.eventadapter.TextItemEventAdapter;

import org.eclipse.birt.report.engine.api.script.element.ITextItem;
import org.eclipse.birt.report.engine.api.script.IReportContext;
public class FileRead extends TextItemEventAdapter {
public void onPrepare( ITextItem TextItem, IReportContext reportContext )
{
try
{
FileInputStream fstream = new FileInputStream("D:adresse.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
String content="";
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
content = content + strLine + "n";

}

//Close the input stream
in.close();
TextItem.setContent(content);

} catch (Exception e ) {
e.printStackTrace( );
}

}

}
thanks

hi
can someone tell me where is the mistake?

Virgil Dodson

Hi mariane,

BIRT supports a Flat File Data Source that is really easy to use and you don't have to navigate the txt file yourself in Java. Otherwise, if you must walk over your data yourself in JAva, then have a look at the Scripted Data Source examples in the DevShare on BIRT Exchange.org. These allow you to write Java code to get your data... and then still use the BIRT designer to design the report.

I need to read a txt file but I need to use it with a relative path and not the assolute path.
Has someone the solution??

jfranken

Create a flat file data source and select "Relative Path" for the home folder.
