If I use our default SEAM Solution:

package de.softcon.ivory.invserver.action.report;

public void download(String filename, File reportFile)
{

byte[] bytes = new byte[1000];

ActionResponseImpl res =

HttpServletResponseWrapper response = res.getRealResponse();

try

while ((read = fis.read(bytes)) != -1)
{
os.write(bytes, 0, read);
}
fis.close();

os.flush();
os.close();

FacesContext.getCurrentInstance().responseComplete();
}
catch (Exception e)
{
if (log.isErrorEnabled())

}

I get the follwing exception with wrong file-names and lost extension (.pdf or

the download use the window-name from *-object.xml instead:

2009-09-08 Thread guenther.her...@softcon.de 
To day I tried a more seam like way:
/**
 * 
 */
package de.softcon.ivory.invserver.action.report;



import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;

import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;

import org.jboss.portal.portlet.impl.jsr168.api.ActionResponseImpl;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Import;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.core.Manager;
import org.jboss.seam.document.ByteArrayDocumentData;
import org.jboss.seam.document.DocumentData;
import org.jboss.seam.document.DocumentStore;
import org.jboss.seam.log.Log;





/**
 * @author mbaumgar

 */
@Name(downloadComponent)
@Import(org.jboss.seam.pdf)
public class DownloadComponent
{
@In private Manager manager;
@In(create = true, value = #{org.jboss.seam.document.DocumentStore}) 
private DocumentStore documentStore;


@In(value = #{facesContext.externalContext})
private ExternalContext externalContext;
/*
@In(value = #{org.jboss.seam.faces.facesContext})
private FacesContext facesContext;
*/
@Logger
private Log log;

public void download(String filename, File reportFile)
{
int read = 0;
byte[] bytes = new byte[1000];

//ActionResponseImpl res = 
(ActionResponseImpl)FacesContext.getCurrentInstance().getExternalContext().getResponse();
//HttpServletResponseWrapper response 
=(HttpServletResponseWrapper)FacesContext.getCurrentInstance().getExternalContext().getResponse();
 ActionResponseImpl res = (ActionResponseImpl) 
externalContext.getResponse();
   
 
//HttpServletResponseWrapper response = res.getRealResponse();
//response.setContentType(application/xls);
//response.setContentLength((int) reportFile.length());
//response.setHeader(Content-Disposition, attachment; filename=\ + 
filename + \;);
//log.info(Content-Disposition attachment; filename=\ + filename + 
\;);
//log.error(Content-Disposition attachment; filename=\ + filename + 
\;);
try
{
//ServletOutputStream os = response.getOutputStream();
ByteArrayOutputStream os = new ByteArrayOutputStream();

FileInputStream fis = new FileInputStream(reportFile);

while ((read = fis.read(bytes)) != -1)
{
os.write(bytes, 0, read);
}
fis.close();
//
//os.flush();
//os.close();
byte[] binaryData = os.toByteArray();
DocumentData data = new ByteArrayDocumentData(report,
new DocumentData.DocumentType(pdf, application/pdf),
binaryData);
String docId = documentStore.newId();
documentStore.saveData(docId, data);
String documentUrl =
documentStore.preferredUrlForContent(
data.getBaseName(),
data.getDocumentType().getExtension(),
docId);
FacesContext.getCurrentInstance().getExternalContext().redirect(

manager.encodeConversationId(documentUrl));

//
FacesContext.getCurrentInstance().getExternalContext().redirect(reportFile.toURI().toString());
//FacesContext.getCurrentInstance().responseComplete();
//facesContext.responseComplete();
}
catch (Exception e)
{
if (log.isErrorEnabled())
{
log.error(DownloadComponent.class, e);
}
}
}
}


But the injections did not succed. I got:

org.jboss.seam.RequiredException: @In attribute requires non-null value: 
downloadComponent.#{org.jboss.seam.document.DocumentStore}
at org.jboss.seam.Component.getValueToInject(Component.java:2335)

I use PorteltBridge Version CR2 with SEAM jboss-seam-2.1.2.CR2

Any hints how to correct generate PDF an XLS Files and download them with 
correct filename and extension (.pdf and .xls) are welcome.

Kind regards

Günther Herndl
