.xhtml

            </h:form>
               ...
            </h:form>
            <h:form enctype="multipart/form-data">
                <p:fileUpload value="#{contratosMB.fileContrato}" mode="simple"/>

                <p:commandButton value="Submit" ajax="false"  
                                 actionListener="#{contratosMB.upload}" update=":form2:formgen:growl"/>
            </h:form>

contratosMB.java

 public void upload() {  
        if(fileContrato != null) {  
            JsfUtil.addSuccessMessage("Se ha cargado correctamente el archivo: " + fileContrato.getFileName());

    }  

I was read some question like this, but nothing was help me... i was add commons-fileupload and commons-io to the project, but dont work not go inside upload method, dont send exception.

Answer 1

Try changing

actionListener="#{contratosMB.upload}"

to

action="#{contratosMB.upload}" .

Check this out : Differences between action and actionListener

Answer 2

it working creating and editing faces-config:

    <dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId> commons-fileupload</artifactId>
    <version>1.2.1</version>
</dependency>
<dependency>
    <groupId>commons-io</groupId>
    <artifactId> commons-io</artifactId>
    <version>1.4</version>
</dependency>

but dont work full for me because form uploader is inside to other form...

   <h:form>
  ...
        <h:form enctype="multipart/form-data">  

            <p:messages showDetail="true"/>  

            <p:fileUpload value="#{contratosMB.fileContrato}" mode="simple"/>  

            <p:commandButton value="Submit" ajax="false"  
                             actionListener="#{contratosMB.upload}"/>  

        </h:form>  
    </h:form>

any body can tell me why??

Answer 3

Nesting 'form' elements is illegal. Try to upload file in advanced mode and use FileUploadListener to access FileUploadEvent and data.
