Hello Marius,
I could make the webservice and PoC works but I am not using the method
$jsontool.serialize.
What is the impact if I not use this serialize method?
Ps.: I have updated the documentation.

Thanks.

Hello People,
We are planning to develop an extension that will link and show the documents of a
specific wiki spacially allowing the user explore the page dynamically. The idea is
similar to the "Just map it" extension.
Our first step was to look some javascript framework available to draw the relationships
that could work for us and we came to conclusion that the sigma.js or d3.js will work
fine...
But, I am worried with the data connection, how can I parse the data from the DB to the
extension dynamically?
Do you think the kind of webservice bellow could
work?

The direction is ok, but:
* you should use the 'get' action instead of 'view' to access the
webservice:
$xwiki.getURL('Main.WebService', 'get', $escapetool.url({
'outputSyntax': 'plain',
'limit': 10
}))
* the webservice should build the JSON in memory using plain Java objects (maps, lists,
strings, numbers, boolean) and then serialize it. In Velocity you can use:
$jsontool.serialize({
'foo': [1, 2, 3],
'bar': {
'color': 'red',
enabled: true
},
'name': 'XWiki'
})
For writing the webservice I would start with Velocity and then move to Groovy but only if
really needed.
Hope this helps,
Marius
Thank you!

$jsontool.serialize brings two important advantages:
(1) No need to manually escape the values you put in your JSON.
Otherwise you need to write something like:
'key1': '$escapetool.json($value1)',
'key2': '$escapetool.json($value2)',
...
which is error prone. We used to generate the live table results this
way and we forgot to escape a few values causing important bugs.
(2) It's way easier to customize/modify the Java object before
serializing it than customizing the code that generates the JSON
string. Take this example:
{
totalCount: 32,
rows: [
{id: 'foo', name:'Foo Abc', age: 29},
{id: 'bar', name: 'Bar Xyz', age: 17},
...
]
}
Now, imagine that at some point you'll have to add a new property per
row, but just for one use case. You should not modify the default
JSON. You just need to extend it somehow. If you build the JSON in
memory then there's no problem, you can write:
#foreach ($row in $jsonObject.rows)
#set ($row.additionalProperty = 'some value')
#end
just before serializing the $jsonObject. In other words you can reuse
entirely the code that generates the default JSON. While in you case,
you'd have to rewrite some of the Velocity macros that 'print' the
JSON, duplicating code, which is a maintenance hell.
Hope this convinces you to use $jsontool.serialize() :)
