rich:fileUpload getting NullPointerException, code similar w
Hi,
Im trying the <rich:uploadFile> tag from Richfaces, and I ran into error, I was kinda hoping i could get some info from the forum.
my code is as follows
<body>
<f:view>
<h:form>
<rich:fileUpload fileUploadListener="#{uploadBean.listener}"
id="upload"
acceptedTypes="jpg, gif, png, bmp" >
</rich:fileUpload>
</h:form>
</f:view>
</body>
My uploadBean class has listener method, and it looks like the following:
public void listener(UploadEvent event) throws Exception {
log.debug("listener called");
UploadItem item = event.getUploadItem();
File file = new File();
file.setLength(item.getData().length);
file.setName(item.getFileName());
file.setData(item.getData());
log.debug(file.getName());
}
Basically, it looks almost identical with the RichFaces livedemo. However, I am getting the following error:
