[jboss-user] [JBoss Portal Users] - Re: ava.lang.ClassCastException: org.jboss.portal.portlet.im

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;





/**

 */
@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
