Hi users,
I am wondering on how to create an XClass from java, and bind it to a
class-sheet to be used to represent several objects as XWiki pages. How can
I achieve that in a way that allow me to incrementaly update the object
every time a modification is performed?
Thanks for your help,
Giordano.

If this class is supposed to be available in the wiki even if not yet
used in an object the simplest is usually to do like most standard
classes generated from java and register a component extending
com.xpn.xwiki.internal.mandatory.AbstractMandatoryDocumentInitializer.
You can find various examples in oldcore.

Yes conceptually speaking, the idea is to write an EventListener component that listens to
the ApplicationReadyEvent event and then in the onEvent() method, create your xclass and
perform all the operations you need.
As Thomas mentioned, you could also extend AbstractMandatoryDocumentInitializer although
this is not a public API and it may be removed or modified in the future. Note that
MandatoryDocumentInitializer is a public API.

New subject: [xwiki-users] How to create an XClass and bind to a sheet
Thank you guys,
Actually I didn't understand any of your suggestions, I have added two
method in "*MyObject*" java class, that are:
//this to create an XClass and bind it with a sheet
crateXClass(SpaceReference spaceRefe, XWikiContext context){
try{
String className = "Instance";
String sheet = className + "Sheet";
DocumentReference docRef = new DocumentReference(className,
spaceRefe);
XWiki wiki = context.getWiki();
XWikiDocument doc = wiki.getDocument(docRef, context);
BaseClass xclass = new BaseClass();
xclass.addTextField("id", "id", 30);
xclass.addTextField("name", "name", 30);
xclass.addTextAreaField("description", "description", 40,
5);
xclass.addTextField("type", "type", 30);
xclass.addTextAreaField("incoming", "incoming", 40, 5);
xclass.addTextAreaField("outgoing", "outgoing", 40, 5);
doc.setXClass(xclass);
BaseObject obj =
wiki.getObjectFromRequest("XWiki.ClassSheetBinding", context);
obj.set("sheet", sheet, context);
doc.addXObject(obj);
docRef = new DocumentReference(sheet, spaceRefe);
doc = wiki.getDocument(docRef, context);
String content = "{{velocity}}\n";
content = content + " #set($class = $doc.getObject('";
content = content + spaceRefe.getName() + "." + className;
content = content + "').xWikiClass)\n";
content = content + " #foreach($prop in $class.properties)\n";
content = content + " === $prop.prettyName ===\n";
content = content + " $doc.display($prop.getName())\n";
content = content + " #end\n";
content = content + "{{/velocity}}\n";
doc.setContent(content);
doc.setTitle("#if($doc.fullName == '" + spaceRefe.getName() +
"." + sheet + "')" + sheet
+ "#{else}$doc.title#end");
wiki.saveDocument(doc, context);
} catch (XWikiException e) {
e.printStackTrace();
}
-----------------------------------------------------------------------
public BaseObject createXObject(String spName, XWikiContext xcontext) {
XWiki wiki = xcontext.getWiki();
BaseObject obj;
try {
obj = wiki.getObjectFromRequest(spName + ".Instance", xcontext);
obj.set("id",this.id, xcontext);
obj.set("name",this.iName, xcontext);
obj.set("description",this.description, xcontext);
obj.set("type",this.eClass, xcontext);
String in = "";
String out = "";
for (int k = 0; k < this.incoming.size(); k++) {
in = in + "* [[" + this.incoming.get(k) + "]] \n";
}
for (int k = 0; k < outgoing.size(); k++) {
out = out + "* [[" + this.outgoing.get(k) + "]] \n";
}
obj.set("incoming",in,xcontext);
obj.set("outgoing",out,xcontext);
return obj;
}catch (XWikiException e) {
e.printStackTrace();
}
return null;
}
--------------------------------------------------------------------------------
But if I update the wiki (through specified button), I get all my new pages
without any content, plus one new page with this title:"*#if($doc.fullName
== 'BSS Rome.InstanceSheet')InstanceSheet#{else}$doc.title#end" *that
should be the Sheet created through the createXClass() method, that display
a Velocity error saying that :

Sorry for the long post guys, but this is my Master Thesis project and
I am really tired because everytime that I think to be near to the end
something unknown arise adding complexity.
Thank you,

New subject: [xwiki-users] How to create an XClass and bind to a sheet
Hi,
XWikiUsersDocumentInitializer[1] is an example of a
MandatoryDocumentInitializer component (what Thomas mentioned). There are
others available in the code if you search [2] for java files containing
"DocumentInitializer" in their name (or better yet, in the IDE/Eclipse,
that implement the interface "MandatoryDocumentInitializer").
The idea is that, when XWiki starts up (or when you first access a
wiki/subwiki), all the mandatory documents of that wiki will be initialized
by calling these MandatoryDocumentInitializer (java) components that will
make sure to add any missing properties to the document they are
initializing. The document that is being initialized is in the component's
name [3]. This way, you can be sure that your mandatory document/class/etc.
is there at startup.
We`ve used this mostly for classes, but the MandatoryDocumentInitializer
component can be used for whatever type of document you need.
Hope this helps,
Eduard

Sorry for the long post guys, but this is my Master Thesis project and
I am really tired because everytime that I think to be near to the end
something unknown arise adding complexity.
Thank you,
Giordano.

You can find various examples in oldcore.
Yes conceptually speaking, the idea is to write an EventListener
As Thomas mentioned, you could also extend
AbstractMandatoryDocumentInitializer
although this is not a public API it may be removed or modified in the future. Note
that
MandatoryDocumentInitializer is a public API.
Right, I actually forgot it was internal (yes I know I wrote it and I
just copy/pasted the package in the mail :)). I think we should make
it public since it's very useful for extensions and we are using it a
lot.
