How to read announcements in Liferay 6.x?
Junior Member Postagens: 27 Data de Entrada: 14/09/10 Postagens Recentes
I need to get my hands really dirty with Liferay 6.x soon, but my first test drive is just to create a portlet that reads the three latest announcements, and put them to the screen.
I tried to copy jsp code from Liferay announcements portlet, but that way was doomed. My own portlet runs as its own portlet war, and has access only to the portlet-service.jar.
I have tried to look at the JavaDoc, and I see lots of classes, documented that "you must not use this"
So what classes to use? Anyone done this kind of a simple portlet, and has pointers?
I would love to get the book, but I think it is written for Liferay 5.x?

probably something like
There are a number of books out there
the packt development books are for 5.x,
the apress book is for 5.x too
liferay in action & portlets in action cover 6.x
the packt book about using liferay covers 6.x
LinkedHashMap<long, long[]> scopes = AnnouncementsUtil.getAnnouncementScopes(user.getUserId());
List<announcementsentry> entries = AnnouncementsEntryLocalServiceUtil.getEntries(user.getUserId(), scopes, false, AnnouncementsFlagConstants.NOT_HIDDEN, 0, 3);</announcementsentry></long,>

AnnouncementUtil is not available. It does not belong to portal-service.jar
Thanks for the book recommendations!

I tried code:
But it somehow causes MySQL syntax error. While I debugged, I saw that it was trying to get HIDDEN announces, no matter that the flagValue is NOT_HIDDEN. And then I took the SQL statement it generated, and tried it in MySQL query browser, it passed OK there. Then I tried the statement in Netbeans via JDBC, if it was a JDBC problem, but no, it works there too.
Then I changed the getEntries() in format
And that works! But I probably will need a more fine grained getter, to get different types of announcements...
<%
LinkedHashMap<long, long[]> scopes = null; // AnnouncementsUtil.getAnnouncementScopes(user.getUserId());
List<announcementsentry> results = null;
int flagValue = AnnouncementsFlagConstants.NOT_HIDDEN;
// Get 3 last entries
results = AnnouncementsEntryLocalServiceUtil.getEntries(
user.getUserId(), scopes, false, flagValue, 0, 3);
for (int i = 0; i < results.size(); i++) {
AnnouncementsEntry entry = results.get(i);
String className = StringPool.BLANK;
if (i == 0) {
className += " first";
}
if ((i + 1) == results.size()) {
className += " last";
}
