Dear Jeremie,
sorry for the distracting. The object is here not important. I only
search for ALL documents which contain one object. From that document i
want to read the title (if i get no value from the object). I tried now
the queryModule with
List<DocumentReference> foundReferences = new
ArrayList<DocumentReference>();
try {
Query query = queryManager.createQuery("SELECT
doc.space, doc.name FROM Document doc, doc.object(" + className + ") AS
obj", Query.XWQL);
List<Object[]> queryResults = query.execute();
for (Object[] result : queryResults) {
foundReferences.add(new
DocumentReference(context.getDatabase(), (String) result[0], (String)
result[1]));
}
} catch (Exception e) {
e.printStackTrace();
}
if (foundReferences.size()>0) {
for (DocumentReference documentReference :
foundReferences) {
XWikiDocument doc =
context.getWiki().getDocument(documentReference, context);
System.out.println(doc.getTitle());
}
}
That doens't help at all. I don't get the title from documents. Why is
that? You have an idea? Should title = doc.getTitle(); not give back the
title? It has nothing to do with the attachend object.
PS: I created all the documents with "AppWithinAMinute". The documents
show a title when i open the document in the browser, so why can i read
the title with a query from java-side? If you have no idea, than it
seems that it is a bug. Then i send an example-code which reproduce this
to jira.
Regards,
Matthias

Hi,
You should be careful with Nabble (or such tools) formatting, that
generates syntax that is neither plain text nor html, and your code
samples
are then not displayed at all in regular email clients ...
I put your samples back below:
groovy:
String hql = "SELECT obj.name FROM BaseObject obj WHERE
obj.className='Space.SomeClass'";
def results = xwiki.search(hql);
for (int i = 0; i < results.size(); i++) {
if(!results.get(i).equals("Space.SomeClassTemplate")) {
Document doc = xwiki.getDocument(results.get(i));
Object obj = document.getObject("Space.SomeClass");
if (obj!=null) {
Property property = obj.getProperty("title");
if (property!=null) {
title = property.getValue();
} else {
title = document.getTitle();
}
println(title)
}
}
java:
String className = "Space.SomeClass";
String sql = "SELECT obj.name FROM BaseObject obj WHERE
obj.className='" +
className + "'";
List<Object> results = context.getWiki().search(sql, context);
if (results != null) {
for (Object object : results) {
String docName = object.toString();
XWikiDocument doc = context.getWiki().getDocument(docName, context);
EntityReference entRef = doc.resolveClassReference(className);
BaseObject baseObject = doc.getXObject(entRef);
if (baseObject != null) {
System.out.println(doc.getTitle()+ baseObject);
}
}
Note that you don't do the same thing regarding title in groovy and in
java, obj.getProperty("title") is not at all equivalent to
document.getTitle() ...
It's likely that your document has no title, and what "works" in
groovy is
to get a property "title" from an object of this doc. At least, I
don't see
any other reason for this empty title :)
Side note, in java you could inject the QueryManager instead of using the
"search" api, as you only do a read-only query:
@Inject
private QueryManager queryManager;
See : http://extensions.xwiki.org/xwiki/bin/view/Extension/Query+Module
Hope this helps,
Jeremie

Hi All,
i have a working groovy script which is:
I use a class and add an object to a document. Everytime a object is
attached i look for it with the query and do something with the
objects.
the
strange thing is that i try to port it to a service to java. where i
get in
groovy an title of the document it is NOT given
in java.
The java code of the service
I didn't get it. Did i do something wrong? i never get a title of the
document. I can read the document, the object of the document, but i
did
not
get the title. I tried also to get translated documents because i use
locals
de and en. But even there i get the title back.
You know why?
Regards,
Matthias
