Hello,
I am trying to develop a report using Scripted Data Source. I have a
sample java file which will populate the data which i wud be then feeding
to the tabel in the report. When i am placing the classes files in the
Eclipse/plugins/...viewer/scriptlib its working fine in the birt report
viewer
But i want it to get it working with a java standalone application. I have
a java program that would use BIRT report Engine API's to access the
rptdesign file and would generate the report
The java program :
//---------------- Java Program to Generate Report -------------------
import java.util.HashMap;
import org.eclipse.birt.report.engine.api.*;
public class viewtest2 {
public static void main(String[] args) {
EngineConfig conf = null;
ReportEngine eng = null;
IReportRunnable design = null;
IRunAndRenderTask task = null;
HTMLRenderOption renderOption_html=null;
HashMap<String,HTMLRenderOption> contextMap = null;
PDFRenderOption renderOption_pdf = null;
HashMap<String, PDFRenderOption> contextMap_pdf = new
HashMap<String,PDFRenderOption>();
DOCRenderContext renderOption_doc = new DOCRenderContext();
conf = new EngineConfig();
conf.setEngineHome("C:/Program
Files/BIRT/birt-runtime-2_2_0/ReportEngine");
eng = new ReportEngine( conf );
try
{
design =
eng.openReportDesign("C:/tmp/Test_Report.rptdesign");
}
catch (Exception e)
{
System.err.println("An error occured during the opening of
the report file!");
e.printStackTrace();
System.exit(-1);
}
task = eng.createRunAndRenderTask(design);
renderOption_html = new HTMLRenderOption();
renderOption_html.setImageDirectory("image");
contextMap = new HashMap<String,HTMLRenderOption>();
contextMap.put( EngineConstants.APPCONTEXT_HTML_RENDER_CONTEXT,
renderOption_html );
task.setAppContext( contextMap );
renderOption_html.setOutputFileName("c:/tmp/output.html");
renderOption_html.setOutputFormat("html");
task.setRenderOption(renderOption_html);
try
{
task.run();
}
catch (Exception e)
{
System.err.println("An error occured while running the
report!");
e.printStackTrace();
System.exit(-1);
}
System.out.println("All went well. Closing program!");
eng.destroy();
}
}
//---------------The Java File to populate data--------------------------
import java.net.URL;
import java.io.DataInputStream;
import java.io.InputStream;
public class EvalTest {
DataInputStream dis;
public DataInputStream readData()
{
try
{
URL rurl= new java.net.URL("http://rss.cnn.com/rss/cnn_topstories.rss");
InputStream is = rurl.openStream();
dis = new java.io.DataInputStream( new java.io.BufferedInputStream( is ));
}
catch(Exception e)
{
e.printStackTrace();
}
return dis;
}
}
//------------------------------------------
And in the scripted dataset i used following codes .
//---------- open---------
sampleClass12 = new Packages.EvalTest();
dis = sampleClass12.readData();
// --------fetch------
if( ( rline=dis.readLine()) != null ){
dataSetRow["Test"] = rline;
return true;
}
return false;
//--------------------
I am new to BIRT and am not able to figure out how to execute this without
placing th jar files in the scriptlib or WEB_INF/lib directory
am getting the following error :
Aug 21, 2007 10:08:18 PM

You can try the following before starting up the platform.
System.setProperty( EngineConstants.WEBAPP_CLASSPATH_KEY,"c:/myclasses" );

Hello Jason
Thankz for the help .. but still am not able to get the program running.
I am able to get the output when i place my jar files in the scriptlib or
WEB_INF/lib directory of the viewwer pluggin. But what my need is i want a
java standalone application with the .rptdesign file and the
reportgeneration java files and the Script java files (to be used as
scripted data source) to be together in the same eclipse java project and
then execute it .. Its giving error as :

Surya,
Did you try?
System.setProperty(
EngineConstants.WEBAPP_CLASSPATH_KEY,"c:/myclasses/myjar.jar " );

Surya,
You can use the application context object to do this. You can set this
for the task or the engine like:
DummyClass dl = new DummyClass();
//Configure the Engine and start the Platform
config = new EngineConfig( );
HashMap hm = config.getAppContext();
hm.put( "dummy", dl);
config.setAppContext(hm);
