Uploading files

Dear List,

I am trying to upload files with Turbine, so I have created an Action that
looks as follows:

//doPerform ...
ParameterParser params = data.getParameters();
FileItem fi = params.getFileItem("foto");
String realPath = data.getServletContext().getRealPath("/");
File file = new
File(realPath+TurbineResources.getString("services.UploadService.repository"
)

+File.separator+"fotos"+File.separator+"file.gif");
file.delete();
file.createNewFile();
FileOutputStream fos = new FileOutputStream(file);
fos.write(fi.get());
fos.flush();

However, I get a NullPointerException because the sentence fi.get() returns
null. The fact is that when I try to get anything from the FileItem, this
object returns null.

Do you know how can I solve this?

Thanks,

Otto.

Thanks, I think I was forgetting the multipart statement in the HTML

Otto.

i didn't try your code, but this works for me:

import org.apache.turbine.services.servlet.TurbineServlet;
import org.apache.turbine.util.upload.FileItem;

import java.io.File;

[...]

            FileItem fileItem = data.getParameters().getFileItem("file");
            if (fileItem != null)
            {
fileItem.write(TurbineServlet.getRealPath("YourPathToUploadedFiles" +
FileName));
}

additionally, make sure you've got:
<form method="post" enctype="multipart/form-data" action=[...]>

in your webpage that holds the upload form.

hope that helps,

rick
