Hi,

I'm trying to upload files with just one button (so, the "upload" and the "finish" button together.)

Now, I made a copy of UploadFileServlet and worked with the copy.

This code works fine

// —————————————-
         StringBuilder builder = new StringBuilder();

         builder.append(Repository.getMimeTypeForFileName(FacesContext
               .getCurrentInstance(), bean.getFileName()));
         String mime = builder.toString();

         // set mimetype of content
         addwiz.setContentType(mime);

         // set inline Edit if mimetype = HTML
         addwiz.setInlineEdit(addwiz.getContentType().equals(
               MimetypeMap.MIMETYPE_HTML));

         // Try and extract metadata from the file
         ContentReader cr = new FileContentReader(this.file);
         cr.setMimetype(addwiz.getContentType());

         // create properties for content type
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map<QName, Serializable> contentProps = new HashMap<QName, Serializable>(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5, 1.0f);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// if (Repository.extractMetadata(FacesContext.getCurrentInstance(),
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// cr, contentProps))
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;addwiz.setAuthor((String) (contentProps
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.get(ContentModel.PROP_AUTHOR)));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;addwiz
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.setTitle((String) (contentProps
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.get(ContentModel.PROP_TITLE)));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;addwiz.setDescription((String) (contentProps
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.get(ContentModel.PROP_DESCRIPTION)));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// }

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (addwiz.getTitle() == null) 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; addwiz.setTitle(bean.getFileName()); 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But, now, I want to upload the files affcourse:

addwiz.quick(this.file, null);
‍‍‍

public String quick(File fileContent, String strContent)
   {      
      String outcome = quicksaveContent(fileContent, strContent);
      
      // now we know the new details are in the repository, reset the
      // client side node representation so the new details are retrieved
      if (this.editMode)
      {
         this.browseBean.getDocument().reset();
      }
      
      return outcome;
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now, in the saveContent, I always get a nullpointer at the FacesContext.getCurrentInstance()!
At the first, I get this exception also at the first code, but I made muy way around it.

someone told me that this problem could be that the FacesContext.getCurrentInstance() use a HTTP request and the Servlet not, so that's why I get the nullpointer, but here stops my knowlidge of java 

If you also can see in the first code i did

// if (Repository.extractMetadata(FacesContext.getCurrentInstance(),

so i would not have a nullpointer offcourse

so, if someone could help me?

thx

Or is it possible to use the method

AddContentWizard.Finish‍

in the UploadFileServlet ???
