After upgrade to liferay 6 : NullPointerException getting a document
Regular Member 帖子: 100 加入日期: 10-10-4 最近的帖子
Hi all,
we are in the testing phase of our upgrade process. We managed to upgrade an installation of liferay5.2.3 to Liferay 6.0.6; testing the results we found an ugly error ( see above ) .
The error appears if, in a public page, there is a link to a document that is supposed to require authentication. If the user requesting the document is logged in then there is no problem at all, if the user is not logged in ( guest ) then we recieve the following stack trace :
This obviously leads to a page where the user sees an Internal Server Error message.
We tested the same path in the old version ( 5.2.3 ) and everything runs smoothly ( the non authenticated user sees a page that tells him/her that he/she is not authorized ).
Is there anything you suggest to check ?
TIA

This obviously leads to a page where the user sees an Internal Server Error message.

Is there anything you suggest to check ?

Did some more tests.
I fired a bundle, created a public page, uploaded a document, secured it and linked it in the public page I just created. Trying to open the document with the guest user leads to the expected behavior ( unauthorized access ) .
This leads me to thing that something must have gone nuts during the upgrade process.
I digged a little into the code :
and as far as I can understand ( without debugging ) the problem seems to be that
return a NULL object making the test
throw the aforementioned exception
Is there anything I can do to double check the data or do you actually think this is a bug ?

I digged a little into the code :
DLFileEntry fileEntry = null;
if (Validator.isNotNull(uuid) && (groupId > 0)) {
try {
fileEntry = DLFileEntryServiceUtil.getFileEntryByUuidAndGroupId(
uuid, groupId);
folderId = fileEntry.getFolderId();
name = fileEntry.getName();
}
catch (Exception e) {
}
}
if (fileShortcutId <= 0) {
if (Validator.isNotNull(name)) {
fileEntry = DLFileEntryServiceUtil.getFileEntry(
groupId, folderId, name);
title = fileEntry.getTitle();
}
else if (Validator.isNotNull(title)) {
fileEntry = DLFileEntryServiceUtil.getFileEntryByTitle(
groupId, folderId, title);
name = fileEntry.getName();
}
}
else {
DLFileShortcut fileShortcut =
DLFileShortcutServiceUtil.getFileShortcut(fileShortcutId);
folderId = fileShortcut.getToFolderId();
name = fileShortcut.getToName();
fileEntry = DLFileEntryLocalServiceUtil.getFileEntry(
groupId, folderId, name);
}
if (Validator.isNull(version)) {
if (Validator.isNotNull(fileEntry.getVersion())) {
version = fileEntry.getVersion();
}
else {
throw new NoSuchFileEntryException();
}
}
and as far as I can understand ( without debugging ) the problem seems to be that
fileEntry = DLFileEntryLocalServiceUtil.getFileEntry(
groupId, folderId, name);
return a NULL object making the test
if (Validator.isNotNull(fileEntry.getVersion())) throw the aforementioned exception

Did came to same problem and made issue LPS-30480 regarding the null pointer exception. It might be still valid at trunk.
