Question

I tried to use p:fileUpload but fileUploadListener method wasn't called, nor any exception generated. Without PrettyFaces, file upload works fine.

After some research, I found that Rewrite FAQ (http://ocpsoft.org/rewrite/docs/faq) answer for the question "Why are file uploads not working correctly any more?" could be the solution, but tested only on Tomcat. I tried that on GlassFish but without success.

Then I found a post in OcpSoft Forum that solves my problem: http://ocpsoft.org/support/topic/pretty-primefaces-fileupload/page/2/#post-25781. Just put the file upload code in other page source and reference that with a html iframe tag.

Ok, problem solved, but I'm not satisfied with iframe solution, whereas fileUploadListener method should be called without workaround. So, anyone knows how to configure in a way that file upload works with PrettyFaces?

Xhtml source code:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:p="http://primefaces.org/ui">

    <h:head></h:head>

    <h:body>

        <h:form>
            <p:fileUpload fileUploadListener="#{fileUploadMB.handleFileUpload}" auto="true"
                update="fileName" />

            <h:outputText id="fileName" value="#{fileUploadMB.uploadedFileName}" />
        </h:form>
    </h:body>

</html>

Managed bean:

@ManagedBean
@ViewScoped
@URLMapping(pattern = "/index", viewId = "/index.xhtml")
public class FileUploadMB {

    private UploadedFile uploadedFile;
    private String uploadedFileName;

    public void handleFileUpload(FileUploadEvent evt) {
        this.uploadedFile = evt.getFile();
        this.uploadedFileName = evt.getFile().getFileName();
    }


    public String getUploadedFileName() {
        return uploadedFileName;
    }


    public void setUploadedFileName(String uploadedFileName) {
        this.uploadedFileName = uploadedFileName;
    }
}

And web.xml:

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

<context-param>
    <param-name>com.ocpsoft.pretty.BASE_PACKAGES</param-name>

Was it helpful?

Solution

This is probably a filter chain problem. Try adding the following on your register filters:

<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>

See more in prettyfaces faq question 2.

OTHER TIPS

It wasn't working for me either with Primefaces 5.0 & Prettyfaces Rewrite 2.0.12-final on Tomcat 7.0.41.

But After I removed this part from my web.xml

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>
        org.primefaces.webapp.filter.FileUploadFilter
    </filter-class>
    <init-param>
        <param-name>thresholdSize</param-name>
        <param-value>51200000</param-value>
    </init-param>
    <init-param>
        <param-name>uploadDirectory</param-name>
        <param-value>/uploadedFilesDirectoryForGlassfish</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

and added to context.xml this:

<Context allowCasualMultipartParsing="true">

p:fileUpload started working all fine from the rewritten urls as well.

This page might be useful.

But Wait,

Just observed it was working for small file uploads only, for large file uploads fileUpload listener is still not triggered. Anybody with solutions ?
