Hi all,

I'm using ZK 7.0.3 with Spring Security 3.2.7 on a Ubuntu Server with Java SDK 7 and Tomcat 8

Everything works fine, but I encounter a problem with ZK's file upload.

When uploading a file, the upload process gets 'stucked' when the process bar reaches 100%. From this time on, nothing happens.

My ZUL file

<zk>
  <div id="theParentDiv" apply="${myController}" vflex="1">
    <vlayout>
      <groupbox title="File upload" >
        <button id="fileUpload" upload="true" label="Upload" 
         image="somepic.png"/>              
      </groupbox>
    </vlayout>
  </div>
</zk>

My Controller

@Controller
@Scope("session")
public class MyController extends SelectorComposer<Component> {

  @Wire
  Button fileUpload;

  @AfterCompose
  public void afterCompose(@ContextParam(ContextType.VIEW) Component view) {
    Selectors.wireComponents(view, this, false);
  }

  public void doAfterCompose(Component comp) throws Exception {
    super.doAfterCompose(comp);
// ...
  }

  // ...

  @Listen("onUpload=#fileUpload") 
  public void upload(UploadEvent event){            
    logger.info("upload event");  // NEVER REACHED
    final Media media = event.getMedia();
    if(media.isBinary()) {
      // complain
      return;
    }

    // process it
  }
}

When I look into the temp directory of my tomcat application on the server, I do see the uploaded file:

drwxrwxrwx 2 root root     4096 Jun 17 15:42 .
drwxr-sr-x 9 root staff    4096 Jun 17 15:15 ..
-rw------- 1 root root        8 Jun 17 15:42 imageio3741336634515839675.tmp
-rw-r--r-- 1 root root  1042112 Jun 17 15:42 upload_dea8c8ae_78f4_41a2_9481_b67144e339cf_00000000.tmp

I don't have a clue why the file upload gets stucked. Could the file permissions be the problem (Tomcat was started via 'sudo'; so I guess it is OK)?

The problem seems to be very similar to the one decribed here (no solution so far):

forum.zkoss.org/question/81047/uploadevent-is-not-triggering-after-file-upload/ (sorry, not enough karma for posting a link)

Just to mention: beside the above code I also tried a version with

<button id="fileUpload" label="Upload" />

and

@Listen("onClick=#fileUpload")  
public void justUpload() {
  Fileupload.get();
}

@Listen("onUpload=#theParentDiv")   
public void onceUploaded(UpdateEvent event) {
  // NEVER REACHED
  final Media media = event.getMedia();
  //
}

but I ran into the same issue.

Does anybody know a solution to this problem?

Kind regards, Peter

add this to your http configuration :

http.headers().addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsMode.SAMEORIGIN));

Thank you alexprawira,

this solved the issue!

Regards, Peter

Edit: For ZK 7 with Spring Security 4.x the solution above does not work. Instead, add

http.headers().frameOptions().sameOrigin();

to your SecurityConfig.java file

Hello Peda,

First of all could you please use the code that is included at the following forum post? (It will work for all file types)

http://forum.zkoss.org/question/97558/fileupload-not-working/?answer=97561#post-id-97561

If it still does not work, i suspect it may be related with Spring security.

Best Regards,

Darksu

Hello Darksu,

thanks for you reply. I tried the code you suggested and again I ran into the same issue. So I think it's a Spring security issue (or at least a spring security config issue). I'll try to find a solution there ...

Hello peda,

Yes as mentioned before it probably is a spring security issue.

Could you please upload your spring configuration files so i can check them out?

Best Regards,

Darksu

I still did not figure out why the above code is not working for me and what I could do to enable the file upload. So if some one has some advices/recommendations I would be very pleased.

Kind regards, Peter
