[xwiki-users] calling a java component from JavaScriptExtension

[gervwyk]

Is it possible to call a java component from a JavaScriptExtension? like
this:

In javascript:

require(['jquery'], function ($) {
   $('#ToJava').click(function(){
  var returnValue = $services.mycomponent.mymethod( someNumber );
  // use return value
   });
});

In java: 

 public int mymethod(int num){
   return num +1;
}

I know that I can do the ajax round trip and invoke the method through
velocity:
http://extensions.xwiki.org/xwiki/bin/view/Extension/AJAX+example

-- just wondering if there is a way to shortcut this process by avoiding
velocity and only working in js?
or is my logic flawed?

Re: [xwiki-users] calling a java component from JavaScriptExtension

[gervwyk]

Thanks Jean.

Yes, I understand. I think what would be useful, is a JS function to invoke
a java method server-side, since I find myself doing this ajax round trip
all the time. So what I'm proposing a JS function call, say:

JavaServer.call("mycomponent.mymethod", {JSON data input}, "(return type)'
);

Which runs the ajax in JS required calling a generic xwiki page url with a
velocity script maybe which invokes the java component passed with the JS
parameter and return the "html/text" or "application/json" data as
specified.

Currently I have like 50 static terminal pages which is only used to pass
data from the JS with ajax to a velocity script to a java component and
back. Basically, the only difference in those velocity scripts is the
method name. So kinda feel that it might be possible to "short-cut' this
velocity page, with a standard velocity macro which invokes the passed
method. I'm pretty sure this will add client side "reactive"-like
functionality to xwiki as you can invoke server-side functions from JS
events. In principle like in Meteor.js were you do a
Method.call("methodname",function(){}), although the underlying
architecture differs greatly.

Keep up the good work

[xwiki-users] Returning JSON data from a java component

[gervwyk]

What is the best way to get JSON data from a java component. In my java
component I'm compiling JSONObjects and JSONArrays, I would like to return
this data to my velocity script in JSON format, is this possible? 

something like:

{{velocity wiki="false"}}
#if("$!request.outputSyntax" != '')
  $response.setContentType('application/json')
#end
#set($map = [])
#set ($rightIN =  ${request.rightIN}) 
#set ($spacenameIN =  ${request.spacenameIN}) 
#set($disgard =
$map.add($services.g_pagebuilder.userAccessFindPages($spacenameIN,$rightIN
)))
$jsontool.serialize($map)
{{/velocity}}

and the Java:

  public JSONObject javacomp(String spacenameIN, String rightIN ){
  JSONObject obj = new JSONObject();
  try {
obj.put("spacenameIN ", spacenameIN );
obj.put("rightIN", rightIN );
} catch (JSONException e) {
e.printStackTrace();
}
  return obj;
  }

At the end I would like to access this json object as a data return from an
ajax call. Is this possible?

Thanks
Gerrie

[xwiki-users] XWikiRights for groups on page and children

[gervwyk]

Good day.

I'm trying to write a java component to set rights to a space and the space
children. Normally, the user would set this on the space when clicking on
administer page>users and groups>Rights: page and children, where the user
can set access rights for a group to effect the space and its children. 

I'm trying to achieve this with a java component and currently I'm attaching
an XWikiRights object with the specified group and rights to the
.WebHome page. However, this only effects the one page and not the
children, also view rights only leaves comment and page creating rights
which is not desired. Am I understanding the rights objects wrong? How do I
achieve this in Java, currently I have:

XWikiDocument doc = xwiki.getDocument(docref, xcontext); //
referance to the .WebHome
DocumentReference classdoc =
createDocumentReference(xwikiName,"XWiki","XWikiRights",false);
BaseObject DSErightsobj = doc.newXObject(classdoc, xcontext);
DSErightsobj.set("groups", DSEname, xcontext);
DSErightsobj.set("users", "", xcontext);
DSErightsobj.set("levels", "view", xcontext); // space right
DSErightsobj.set("allow", 1, xcontext);
xwiki.saveDocument(doc, xcontext);

[xwiki-users] Adding users to a user list form a java component

[gervwyk]

Good day.

I'm trying to add users to a users list within a object. After I have
instanciated the object on the document which I want to ammend, how do I
"set" and "get" the user list property in a java component? I have:

BaseObject domainObject = doc.getXObject(referenceClass);
domainObj.set("lisfOfUsers", ??user?? , xcontext);

domainObj is of a class where the "lisfOfUsers" is a List of Users property.
Currently I have the username as a string. I have tried creating a User or
XWikiUser object and setting the property with the object but with no
success.

[xwiki-users] Xwiki html parsing of user list

[gervwyk]

I'm creating a form but I prefer using HTML and bootstrap rather than only
velocity syntax. I have the following problem:

 

I want to insert user selection list into the form. By doing the following:

{{velocity}}
{{html velocity="true" }}

 #set( $tempobj = $doc.newObject('Classes.USR'))
 $tempobj.display('userslist','edit') 


{{html velocity="true" }}
{{/velocity}}

however I get the {{html}} tag around the search box which I don't want. How
can I remove this?
closing and opening the html before and after the call gives rendering
errors. Is there a way to all the  $tempobj.display('userslist','edit')
function without rendering the {{html}} tags?
Which function in java lib will give me a simular output? maybe I can do
this through a java component? 
What output does thedisplayEdit() method in BaseObject class give? 

I tried something like this, but did not work, I might be totally wrong..

  XWikiContext xcontext = this.xwikiContextProvider.get();
  DocumentReference referenceClass = 
resolver.resolve("Classes.USR");
  XWikiDocument doc = xcontext.getDoc();
  BaseObject domainObject = doc.getXObject(referenceClass);
  String disp = domainObject.displayEdit("userslist", xcontext);
  return disp

[xwiki-users] New Javadoc API Reference

[gervwyk]

I there a new JavaDoc API reference availible somewhere?
I'm currently using version 5:
http://maven.xwiki.org/site/docs/xwiki-javadoc-5.0.x/

However I'm finding it really outdated on methods such as
xwiki.checkAccess() and xwiki.getSpaces()

I'm not finding my way to it on the API reference page:
http://platform.xwiki.org/xwiki/bin/view/DevGuide/API

Any advice where to find javadoc for xwiki 7.3?

Re: [xwiki-users] spaces for which the current user has access in a java component

[gervwyk]

Ok. So what I'm trying to achieve is the following:
We have spaces which has user (view/edit) groups and an admin group for that
space. 
I'm currently writing a rights admin tool which shows the admin group users
the spaces which they are the admin of, and they can then select a space to
which they can assign a user group.

In normal workflow terms: We have managers of departments, and project
teams, and we want the managers to give rights to a team within their
department to assign the to a project through a admin tool/ webform, instead
of going to each page and attaching the objects and making mistakes. 

So:
1. I want the managers to see the spaces for which they are admin
2. I what them to assign a group to that space.

I can successfully assign the group to the space, however, having trouble to
let the managers see only the spaces for which they are the admin.

[xwiki-users] spaces for which the current user has access in a java component

[gervwyk]

How do I get all the spaces for which the current user has access in a java
component?

I have the following:

List lstSpaces = new ArrayList();
XWikiContext xcontext = this.xwikiContextProvider.get();
XWiki xwiki = xcontext.getWiki();
lstSpaces = xwiki.getSpaces(xcontext);

Although this successfully returns all the spaces, it also returns the
spaces for which the current user has no "view" or other access rights. Also
it seems that the Java .getSpaces is deprecated and I can't seem to find the
new method for this. http://maven.xwiki.org/site/docs/xwiki-javadoc-5.0.x/
seems outdated as xwiki.getSpaces() is still active in this javadoc, with no
alternative. Is there a new javadoc availible?

[xwiki-users] Get all children from current document in Java component

[gervwyk]

Hello
I'm trying to get all the documents that list the current document as the
perant using:
List  childDocs = doc.getChildrenReferences(xcontext);

where doc is the parent XWikiDocument.

However the function only return an empty list, althoug there is documents
in the space. 

If I print doc.getFullName() its AAA.WebHome.. And all the chldren spaces is
listed under AAA.. how should I reference doc to get say AAA.BBB.WebHome in
the list? or where am I going wrong?

Re: [xwiki-users] Create spaces and page in toplevel space via Java component

Thanks this was exactly what I was looking for. The new structure did cause
some confusion. The "WebHome" concept was confusing until I read the links. 

Thank for clarifying that.

[xwiki-users] Create spaces and page in toplevel space via Java component

[gervwyk]

Hello.
How would I create a new space under Main or the toplevel entity from a java
component. So far I'm doing this, but not sure.. 

DocumentReference docref = new
DocumentReference(serverName,pageSpace,pageName);
if(xwiki.exists( docref, xcontext)){
//skip create do other stuff
}else{ 
   XWikiDocument doc = new XWikiDocument(docref);
   doc.setTitle(pageName);
   DocumentReference docrefparent = new
DocumentReference(serverName,pageSpace,"WebHome");
   doc.setParentReference(docrefparent);
   xwiki.saveDocument(doc, xcontext);
}
Where:
serverName = $request.serverName
pageSpace = "Main"
pageName = "NewPage"

is there anything else I need to set on the document or am I referencing
wrong? Not sure why it is not creating the page..
