hi

i am trying to diaply image or chart report which is designed using birt
report designer.

i used following code to generate HTML output

EngineConfig config = new EngineConfig( );
config.setEngineHome( "E:\\birt" );
HTMLEmitterConfig hc = new HTMLEmitterConfig( );
HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler( );
hc.setImageHandler( imageHandler );
config.setEmitterConfiguration( HTMLRenderOption.OUTPUT_FORMAT_HTML, hc );
ReportEngine engine = new ReportEngine( config );
IReportRunnable report = null;
try{
report = engine.openReportDesign( name );
}catch ( EngineException e ){
System.err.println( "Report " + name + " not found!\n" );
engine.destroy( );
return;
}

if ( showInfo ) {
showReportInfo( engine, report );
}

if ( format != null ){
parseParams( engine, report, params );
IRunAndRenderTask task = engine.createRunAndRenderTask( report );
HTMLRenderOption options = new HTMLRenderOption( );
options.setOutputFormat( format );
String output = name.replaceFirst( ".rptdesign", "." + format );
options.setOutputFileName( output );
task.setRenderOption( options );
task.setParameterValues( params );

try{
task.run( );
}
catch ( EngineException e1 ) {
System.err.println( "Report " + name + " run failed.\n" );
System.err.println( e1.toString( ) );
}
}

engine.destroy( );
}

This code is working fine with Simple reports which contain Tables but its
not working fine with reports which contain images or charts

this code is generating .html file for image reports but image is not
printing.

and aslo i am not clear with the following comments
// HTML reports can have embedded images or charts. Set up the
configuration
// required to write these into a directory in the output directory.
// The HTMLCompleteImageHandler is one provided by BIRT for this purpose.
// Your application can create a customized version to provide alternative
// ways to handle images.

Soultion is very URGENT PLEASE HELP ME REGARDING THIS

sri,

Try

HTMLRenderContext renderContext = new HTMLRenderContext();
renderContext.setImageDirectory("image");
HashMap contextMap = new HashMap();
contextMap.put( HTMLRenderContext.CONTEXT_NAME, renderContext );
task.setContext( contextMap );

right before

HTMLRenderOption options = new HTMLRenderOption( );

sri,

Sorry wrong snippet

from ReportRunner.java

if ( format.equalsIgnoreCase( "html" ) )
{
HTMLRenderContext renderContext = new HTMLRenderContext( );
renderContext.setImageDirectory( "image" ); //$NON-NLS-1$

HashMap appContext = new HashMap( );
appContext.put( EngineConstants.APPCONTEXT_HTML_RENDER_CONTEXT,
renderContext );
task.setAppContext( appContext );
}
