[Wicket-user] FileUpload problem
I've been using wicket 1.2.1 in my application but decided to upgrade to 1.2.3.
Basically everything works except my FileUpload to a Jackrabbit-repository.
My testcases for my DAO:s working against the jackrabbit repo still
works but in my application any file larger than 10kb gets an
exception inside Jackrabbit:
Bad filedescriptor
The only thing I can think of is that the handling of the
FileUpload.getInputStream() has changed somehow.
The code looks like this (parts omitted for clarity):
Button uploadButton;
//document.
add(uploadButton = new Button(upload) {
protected void onSubmit() {
final FileUpload upload =
fileUploadField.getFileUpload();
if (upload != null) {
try {
Document document = getDocument();
document.setName(upload.getClientFileName());
document.setFilename(upload.getClientFileName());
document.setMimeType(upload.getContentType());
document.setInputStream(upload.getInputStream());
document.setSize(upload.getSize());
System.out.println(document.getSize());
document.setContentIsNew(true);
setDocument(document);
} catch (Exception e) {
throw new IllegalStateException(Unable to
upload file, e);
}
}
}
}.setDefaultFormProcessing(false));
Button saveButton = new Button(save) {
protected void onSubmit() {
Document document = getDocument();
...
documentDAO.save(document);
...
}
}
Inside documentDAO.save:
...
Node resNode = null;
try {
resNode = node.getNode(jcr:content);
} catch (PathNotFoundException e) {
resNode = node.addNode(jcr:content, nt:resource);
}
if (document.isContentNew()) {
resNode.setProperty(jcr:mimeType,
document.getMimeType());
resNode.setProperty(jcr:encoding,
document.getEncoding());
resNode.setProperty(jcr:data,
document.getInputStream());
// resNode.setProperty(jcr:size, document.getSize());
resNode.setProperty(jcr:lastModified,
document.getLastModified());
}
The code fails on the jcr:data when accessing document.getInputStream() with:
dao.jcr.DocumentException: error saving document node model

Re: [Wicket-user] FileUpload problem
Sorry for the spam. I read the javadoc for fileupload and noticed in
*bold* that the inputstream is closed between requestsdoh.
Strange that it works for files under 10 kb though
