Gibbon

Hi !
I have a problem with birt 2.3.2 and servlet.

I 'm developping with eclipe 3.4.2 and tomcat 6.0.18.

When I start my tomcat and run for the first time my servlet: no problem. All work good.
But when I submit an other order, I hae this error.
Can you help me ? thanks a lot.

Hi Gibbon,

it might help if you could attach the code for your servlet. From the problem description, it sounds like something to do with Platform.shutdown(), but without the code, it's just an educated guess ;-)

Regards,
Cedric

Gibbon

thanks for your response:

that is my class for pdf generation:

package com.components.stats.reporting;

import java.sql.Date;
import java.sql.Timestamp;
import java.util.Collection;
import java.util.Iterator;
import java.util.logging.Level;

import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.*;

public class ReportGenerator {

public void executeReport(String chemin) {

try{
EngineConfig config = new EngineConfig( );
System.out.println(chemin);
config.setBIRTHome(chemin + "/platform");
config.setLogConfig("C:/Temp", Level.FINEST);

Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );

IReportEngine engine = factory.createReportEngine( config );

IReportRunnable design = null;
//Open the report design
design = engine.openReportDesign(chemin + "/rtpdesign/customers.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
//task.setParameterValue("Top Count", (new Integer(5)));
//task.validateParameters();

//HTMLRenderOption options = new HTMLRenderOption();
//options.setOutputFileName("output/resample/Parmdisp.html");
//options.setOutputFormat("html");
//options.setHtmlRtLFlag(false);
//options.setEmbeddable(false);
//options.setImageDirectory("C:testimages");

PDFRenderOption options = new PDFRenderOption();
options.setOutputFileName("C:/Temp/test.pdf");
options.setOutputFormat("pdf");

task.setRenderOption(options);
task.run();
task.close();
engine.destroy();

System.out.println("fin");

}catch( Exception ex){
ex.printStackTrace();
}
finally
{
Platform.shutdown( );
}
}

}

that is my servlet:

package com.components.stats.reporting;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.IOException;
import java.io.OutputStream;
import java.util.logging.Level;

import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.eclipse.birt.core.exception.BirtException;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.HTMLRenderOption;

public class ReportServlet extends HttpServlet {

protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

ReportGenerator rapport = new ReportGenerator();
ServletContext sc = req.getSession().getServletContext();
rapport.executeReport(sc.getRealPath("/WEB-INF"));
String urlFormulaire = "/index.jsp";
getServletContext().getRequestDispatcher(urlFormulaire).forward(req,resp);

}

}

Ok, I'll give that a try when I get home this evening. In the meantime, would you try commenting out the Platform.shutdown() and let me know if you're still experiencing the same problem?

Gibbon

thanks a lot.

when I comment the Platform.shutdown( ); I have no problem but no pdf are generated.

Gibbon

cypherdj,

did you have the time to try ?

Thanks a lot

Gibbon

no anwser ? =(

cypherdj

Oops, completely forgot about it, I'll try to have a look this evening, sorry...

Gibbon

thanks a lot

cypherdj

Hi Gibbon,

I'll have to install BIRT 2.3.2 as I cannot reproduce your problem with BIRT 2.2.2.

I've tested it with a simple report displaying just a text label.

I've also 2.3.1 installed locally, so I'll test it on that and get back to you.

Gibbon

thanks a lot
