Open report after created [message #90947]

Hi all,
when I create a pdf report from my standalone application and I try to
open it without close application, I obtain an access violation error.
When I open report after I have closed my standalone application, the
message doesn't appare.
I have created the report with the code on the BIRt web site and after I
have destroyed engine with engine.destroy() method; I have put
engine.destroy in finally block but nothing is occurred.

I have need for your help.
Thanks,
Pietro

Here is my code:

EngineConfig config = new EngineConfig( );
config.setEngineHome(System.getProperty("BIRT_HOME")+"/Report Engine");
HTMLEmitterConfig hc = new HTMLEmitterConfig();
HTMLCompleteImageHandler imageHandler = new
HTMLCompleteImageHandler( );
hc.setImageHandler( imageHandler );
config.setEmitterConfiguration(
HTMLRenderOption.OUTPUT_FORMAT_PDF, hc );

ReportEngine engine = new ReportEngine(config);
String name = "data/fattura.rptdesign";
String format = "pdf";
IReportRunnable report = null;
try {
report = engine.openReportDesign(name);
}
catch (EngineException e){
System.err.println( "Report " + name + " not found!\n" );
engine.destroy( );
return;
}
IRunAndRenderTask task = engine.createRunAndRenderTask(report);
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(format);
String output = name.replaceFirst(".rptdesign", "." + format);
options.setOutputFileName(output);
task.setRenderOption(options);
try{
task.run();
System.out.println( "Created Report " + output + ".\n");
}
catch( EngineException e1 ){
System.err.println("Report " + name + " run failed.\n");
System.err.println(e1.toString());
}
finally{
engine.destroy();
}

I'll post what I do to open the resulting report. Be aware that this only
works for HTML output. For PDF, I get the same error you do. I've tried
everything...I have previously posted to ask if anyone knows how to force
BIRT to close the output file, but no one answered. Anyway, I hope this
helps somewhat. BTW, I am on 1.0.1 - don't know if 2.0 has fixed this.

The code tries to open the resulting file and outputs an error message to
the console if it fails. It has some capabilities that you could simplify
if you like (e.g. it allows for blanks in a report name and filename).
The code starts after engine.destroy()

============== code ===============
//open the output file
String filePath = "\"C:/BIRT/";
filePath += resultsReport.getOutputFilename() + "\"";
try {
String[] cmd = new String[3];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = filePath;
System.out.println(cmd[2]);
Process p = Runtime.getRuntime().exec(cmd);
int exitVal = p.waitFor();
System.out.println("Exit code = " + exitVal);
String line = null;
StringBuffer output = new StringBuffer();
BufferedReader procout = new BufferedReader(new
InputStreamReader(p.getInputStream()));
while ((line = procout.readLine()) != null)
{
output.append(line + " ");
}
BufferedReader procerror = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
while ((line = procerror.readLine()) != null)
{
output.append(line + " ");
}
System.out.println(output.toString());
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}

Thanks Mark,
but I have generated a pdf report. I'd like find a solution for open pdf
report after generated. I have BIRT 1.0.1.
