problem with rich:FileUpload

[milankoko]

I am having trouble with richfaces fileUpload component. When uploading should start it throws a null pointer exception and does nothing. I'm running richfaces on tomcat 6.0.16 alongside myfaces 1.2.3, tomahawk 1.1.6 and sandbox 1.1.7.

This is the error I get:

http-80-2 - ERROR [11 jun 2008 12:06:27,921] _ErrorPageWriter - An exception occurred

My code in jsp:

<rich:fileUpload
 uploadData="#{placeActionManager.files}"
 fileUploadListener="#{placeActionManager.imageUploadListener}"
 maxFilesQuantity="3" id="upload"
 acceptedTypes="jpg, gif, png, bmp"
 addControlLabel="#{msgs.addFileControlLabel}"
 clearAllControlLabel="#{msgs.clearAllFilesControlLabel}"
 clearControlLabel="#{msgs.clearFileControlLabel}"
 stopEntryControlLabel="#{msgs.stopFileEntryControlLabel}"
 uploadControlLabel="#{msgs.uploadFileControlLabel}">
 <a4j:support event="onuploadcomplete" reRender="info" />
</rich:fileUpload>

I guess there is some kind of problem rendering the component? pick list from richfaces works fine for me.

[ilya_shaikovsky]

the problems could be in your configuration.

check please an example of config file.

http://jira.jboss.com/jira/browse/RF-3096

[milankoko]

example you posted worked fine, but I still don't know what I'm doing wrong. I even tried putting your fileUpload on my page but it didn't work, same error. Configuration file web.xml looks fine to me:

Now I noticed a couple of differences in contrast to your example:
- I don't use facelets
- I don't have tomahawk.taglib.xml file, since I'm running on Tomcat 6 which doesn't need it i think
- I use <%@ taglib uri="http://richfaces.org/rich" prefix="rich"%> instead of xmlns.
- your examle does not include tomahawk or sandbox or ajax4jsf namespace on page that has fileInput component on it

Could any of this things cause my error? As I mentioned, rich:pickList works fine.

[milankoko]

i fixed that problem. I needed to place core-3.2.1.GA and laguna-3.2.1.GA in my lib folder. Weird because I don't remember I read anything about placing them in classpath in installation instructions. What do they contain? I presume laguna is skin.

But my fileUpload still does not work. I get no errors which is not good since I don't have a clue of whats wrong. When upload of file automatically starts or I choose to start it, file upload listener is not called.

Here is what log says:

What's wrong now?

I did some more testing and found out that if I put latest libraries(3.2.1GA) in your example(which dates to 16.4.2008) your example no longer works. It does not report any error other than Transfer error occurred in fileUpload panel.

[justadreamer2007]

Same thing with me - I had a working (except for IE6) rich:fileUpload from richfaces-3.2.0.SR1, and then I updated to richfaces-3.2.1.GA. Now when you try to upload a file it says 'Transfer error occuried' (should say occurred). What's up with that? Something might have been spoiled between releases I guess.

[milankoko]

I think there is some kind of conflict with latest version of richfaces. Snapshot from 18.4.2008 works fine, but if you switch to latest GA release it gives you transfer error. Funny thing, if you look into your temp files folder in tomcat, the file is actually transferred. Somebody should look into that problem.

[mail.micke]

Just wanted to say it works fine for me.

Just implemented pretty much the same page which is in the livedemo and it works fine.

I'm using :
3.2.1.GA
Mojarra
Seam 2.0.1.GA
Facelets 1.1.14
Tomcat 5.5

In order to help other help you it would probably be useful if you posted some code and more information about your environment.

If you are using Seam have you disabled their multipart filter ?

Cheers,

[mail.micke]

Sorry,
just spotted you environment information. Quite different from mine.

[justadreamer2007]

Hi, [e-mail], thanx for reply because I am trying to resolve this issue too

My environment is:

SJSAS 9.1_ur_1 = glassfish 9.1_ur_1
Mojarra JSF 1.2_08
richfaces-3.2.1.GA

in web.xml I have:

 <filter>
 <display-name>RichFaces Filter</display-name>
 <filter-name>richfaces</filter-name>
 <filter-class>org.ajax4jsf.Filter</filter-class>
 <init-param>
 <param-name>createTempFiles</param-name>
 <param-value>false</param-value>
 </init-param>
 <init-param>
 <param-name>maxRequestSize</param-name>
 <param-value>1000000</param-value>
 </init-param>
 </filter>
 <filter-mapping>
 <filter-name>richfaces</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 <dispatcher>REQUEST</dispatcher>
 <dispatcher>FORWARD</dispatcher>
 <dispatcher>INCLUDE</dispatcher>
 </filter-mapping>

creatTempFile=false means that I want to get my data in the listener in

uploadEvent.getUploadItem().getData()

, the thing is that I even get this data for the first uploaded file, but no onuploadcomplete event is fired - and it says Transfer error occurred.
This seems to be incorrect. createTempFile=true - has the same effect. I will make a simple webapp to demonstrate this behaviour and if the behaviour is the same as in my big app - I will place an issue to jira.

[milankoko]

any hope of this issue being resolved soon? It's kind of disturbing for me to have to work on some snapshot and not having new releases available

What's wrong now?

I found one difference from your web.xml and my example provided in JIRA. You should map myfaces extension filter on Faces Servlet, not on page extension *.jsf. I think this is cause of listener skipping after file uploaded in your application.

Please remove the following code from web.xml:

<filter-mapping>
 <filter-name>MyFacesExtensionsFilter</filter-name>
 <url-pattern>*.jsf</url-pattern>
 </filter-mapping>

Can you please define if uploadListener was called after 'transfer error' message occurred?
Which browser do you use for test?

Thanks.

utilise le code :
