rich:fileUpload returns
I have a rich:fileUpload component in one of my pages, I want my users to be able to upload a CSV file to the server. Here is the page source :
<a4j:outputPanel id="ajxBlackList_19">
<h:inputText id="property_BLACK_LIST" value="#{eventCreation.currentEvent.blackList}" />
</a4j:outputPanel>
<h:outputText id="houtputText_24" value="Charger les valeurs via un fichier CSV :" />
<rich:fileUpload id="black_list_upload" fileUploadListener="#{eventCreation.listener}" listHeight="200" immediateUpload="false" acceptedTypes="csv,txt">
<a4j:support id="a4jsupport_27" event="onuploadcomplete" reRender="ajxBlackList_19" />
</rich:fileUpload>
<h:message id="hmessage_29" tooltip="true" for="black_list_upload" style="color: red;" />
And here is the code of my bean listener (which is never called) :
private UploadItem csvItem;
[...]
public synchronized void listener(UploadEvent event) {
this.setCsvItem( event.getUploadItem() );
// retrieve component id for later use
UIComponent fromComponent = event.getComponent();
String componentId = fromComponent.getId();
String content = null;
// file reading
if (getCsvItem().isTempFile()) {
File csvFile = getCsvItem().getFile();
StringBuilder fileData = new StringBuilder();
try {
BufferedReader reader = new BufferedReader(new FileReader(csvFile));
char[] buf = new char[1024];
int numRead=0;
while((numRead=reader.read(buf)) != -1){
fileData.append(buf, 0, numRead);
}
reader.close();
} catch(Exception e) {
addErrorMessage(e.getMessage(), componentId);
return;
}
content = fileData.toString();
} else {
content = new String(getCsvItem().getData());
}
this.getCurrentEvent().getProperty(DrawingLotsEvent.PROPERTY_WHITE_LIST).setValue(content);
}
Every time I try to upload a file, I get an instant error "Transfer error occured" without my listener being called. I have no trace of any error in a4j log window.
I put this in my web.xml as suggested :
<filter> <display-name>Ajax4jsf Filter</display-name> <filter-name>ajax4jsf</filter-name> <filter-class>org.ajax4jsf.Filter</filter-class> <init-param> <param-name>createTempFiles</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>maxRequestSize</param-name> <param-value>1000000</param-value> </init-param> </filter>
Anyone has any idea ? Or maybe a way to debug this component so I could know WHY this error occurs ?
Thanks a lot.
