I'm not sure if this will help or not, but here's some working
upload code I use to render attachments. Maybe you can template off this.
package forms;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.html.BasePage;
import org.apache.tapestry.request.IUploadFile;
import utils.Log;
import attachment.Attachment;
import attachment.AttachmentData;
import data.DynaObject;
import data.HibHelper;
public class Attachments extends BasePage {
private DynaObject fObject;
private String fObjectClass;
private String fObjectKey;
private IUploadFile fData;
public void setObjectClass(String objectClass) {
fObjectClass = objectClass;
}
public IUploadFile getData() {
return fData;
}
public void setData(IUploadFile data) {
fData = data;
}
public void setObjectKey(String objectKey) {
fObjectKey = objectKey;
if (fObjectClass != null) {
fObject = (DynaObject)
HibHelper.getSession().get(fObjectClass,
fObjectKey);
}
}
public DynaObject getObject() {
return fObject;
}
public void setObject(DynaObject object) {
fObject = object;
}
public String getObjectClass() {
if (fObject == null)
return null;
return fObject.getClass().getCanonicalName();
}
public String getObjectKey() {
if (fObject == null)
return null;
return fObject.getId();
}
public void addNewAttachment(IRequestCycle cycle) {
Attachment a = new Attachment();
a.setFileName(fData.getFileName());
a.setObjectClass(fObjectClass);
a.setObjectId(fObjectKey);
ByteArrayOutputStream bs = new ByteArrayOutputStream();
InputStream is = fData.getStream();
// now read from the input stream and write into our
outputstream
byte[] buffer = new byte[1024];
try {
while (true) {
int length = is.read(buffer);
if (length < 0) {
break;
}
bs.write(buffer, 0, length);
}
is.close();
bs.close();
} catch (Exception e) {
Log.error(e);
}
AttachmentData detail = new AttachmentData();
byte[] temp = bs.toByteArray();
detail.setData(temp);
a.setLength(temp.length);
a.setDetail(detail);
detail.setAttachment(a);
//a.setData(bs.toByteArray());
HibHelper.beginTransaction();
HibHelper.getSession().save(a);
HibHelper.getSession().save(detail);
HibHelper.commitTransaction();
//HibHelper.getSession().save(detail);
//HibHelper.getSession().flush();
// get it out of the session cache since it might be quite
large
HibHelper.getSession().evict(detail);
}
}
