Allowflash is not working, Wildfly 9x

[bizen12]

Hello,

I am using
Wirefly 9x on my proyect. I use richfaces and am trying to enable multiple upload enabling flash but error ocurres when I do that. I tried to debug but the listener is not even called. When I disable flash I can upload files but not multiple.

The XML code is

<ui:composition
xmlns="http://www.w3.org/1999/xhtml"

xmlns:ui="http://java.sun.com/jsf/facelets"

xmlns:h="http://java.sun.com/jsf/html"

xmlns:f="http://java.sun.com/jsf/core"

xmlns:rich="http://richfaces.org/rich"

xmlns:a4j="http://richfaces.org/a4j"

xmlns:c="http://java.sun.com/jstl/core" template="template.xhtml">

And:

<rich:fileUpload style="width:500px;

height:225px;"

fileUploadListener="#{fileUpload.listener}" id="upload"

listHeight="225" listWidth="500" addControlLabel="Examinar"

uploadControlLabel="Cargar" clearControlLabel="" acceptedTypes="zip" allowFlash="true"

maxFilesQuantity="20" onerror="Richfaces.showModalPanel('pnl');"

onfileuploadcomplete="checkError();">

<a4j:support event="onclear" reRender="upload"/>

</rich:fileUpload>

The libraries I am using are:

Thanks a lot.

Well, what is the error? That's the most important part.

Regardless Flash as a technology has been deprecated so that might be your browser doing it, also why are you mixing RichFaces 3.3.3 and 4.5.17?

Hello

The error is that I get a Windows called Exception that says the file can't be uploaded. Then the progress upload bar changes for a message that says "Transfer error occurred". The problema is that java classes are not called so I can't debug in Eclipse or get any extra information.

About 2 question. I am using flash as I want to use multiple file upload, wich is the alternative?. I am migrating from JBoss v5.0 to Wildfly 9x and I am getting a lot of errors. Libraries are the same, maybe that's the error. What configuration do you recommend to me? I think this library you told me 4.5.17 is doing nothing, I added it as a test to solve this issue, but on JBoss v5.0 I don´t have it.

Thanks un lot.

Have you checked the browser console for errors? Or try a different browser. I have no idea how the Flash module works so unfortunately I can't help you there.

RichFaces 3 was released 8 years ago, so I'd recommend migrating to something newer but it's not going to be easy. Even migrating to RichFaces 4 is somewhat difficult and since it's no longer being developed you're better off switching to Primefaces or something.

Yes, I have checked it. And I have tested in 3 browsers.

Maybe posting this in Wildfly forum's section can find anybody who has same question.

Because isn't there any other option to enable multiple upload?

Thanks

[michpetrov]

If the upload isn't working in the browser it's probably not a Wildfly problem.

[bizen12]

So where can the error be? I thought was in Wildfly as in Jboss v5.0 worked with the same code.

[michpetrov]

Have you checked the server logs? There must be some error message somewhere, besides what you see on the page. I guess it might be servlet version in which case you can't do anything.

Hello

finally we found the error. There is a file inside a library called FileUpload.js that generates a URL when u do the post in the upload process. This URL contains first ; and then & provocating the error as Wildfly doesnt accept it. We have to change the first ; for & and the & for a ?  and it would work as this kind of URL wildfly accepts it. Other option is try to configure Wildfly to allow this kind of URL but I don't know how to do it. Do you recommend to modify the library or try to configure wildfly?

Thanks

[michpetrov]

I don't know enough about WildFly settings I'm afraid, modifying the JavaScript file shouldn't be difficult.

[bizen12]

I modified the .js that is inside the .jar library but still doesnt work. In order to do that I opened it with winrar and use notepad++ to modify the .js. I don't know if I have to do anything else as its first time I do that.

People told me that when you have a .js inside a library and you compile it you have .class that have to modify too, but I dont find the FileUpload.class there. Dont't know how to make it work properly

[michpetrov]

Have you rebuilt your app and checked if it uses the new code? JavaScript files are not compiled into .class, that's Java.

[bizen12]

Yes, the problem is that if I open the .js in eclipse I see changes are done but when I launch it on local and I do the fileupload I see the error and the old URL again.

Also if I generate the war, I see the changes dones but when I deploy on a server and try to upload happens the same as in local.

Hi,

finally found the solution.

I modified fileupload.js inside the library Richfaces 3.3.3 ui as said in Modify a jar library in Wildfly 9 or configure WildFly . After that I had the problem the wildfly didn't take library despite I put it on the buildpath and on lib foder.

The solution was in wildfly folder. There is a folder inside wildfly where there are all libraries and there was the old one. I changed it and worked.
