How parse a JSON to List
Hello, how I can parse a JSON to List<Bean>?
Or how I can get the List<Bean> with GetQuery?
I really tried a lot of ways, but I don't have success.

Hi Greg,

Ok. Maybe in the future we can think to move only the wtk drawing part
in a dedicated jar ... let's see later.

The SVG Salamander library is required to build the platform - it just isn't required at runtime if you don't use the Drawing class.

Yes, I agree but as explained here (
http://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html
) could be a good addition as optional dependency.
Take a look at this (from that page):
Why use optional dependencies?
It's not only important to declare optional dependencies in order to
save space/memory/etc. It's vital to control the list of actual
dependencies a person needs in order to use a project, since these
jars may eventually make it into a WAR, EAR, EJB, etc. Inclusion of
the wrong jars may violate a license agreement, cause classpath
issues, etc.
How do I use the optional tag?
A dependency is declared as optional by simply setting the <optional>
tag to true in your dependency declaration.
So, is it Ok for you (and others) ?
Tell me so I can fix it (I've already found the maven repository and
data for referring to svgSalamander), so now I have to make some tests
(for example if the remote repository is not reachable, if Pivot
artifacts will be downloaded and working the same, etc), but I think
the fix will be simple.
Otherwise (probably a more long-term solution) could be to split out
the drawing part of wtk in a dedicated subproject (with its jar) with
their dependencies ... maybe for 2.1 or 3.0 .
Probably could be useful to open a jira ticket for it, and put there
all these info, so we can see when/how to do with this ...
Comments ?

It is optional - it is only necessary if you want to use a Drawing in your app.

Hi all,
just seen the same issue even in the Maven version of downloaded jars:
in the 2.0.1 I'll add the (optional if possible) dependency on
SVGSalamander to WTK.
And, even the demo.jnlp.xsl (which generates jnlp files for demos) has
to be fixed for references to SVGSalamander wrong inside ... or
better, the generated jnlp file is not working.
As soon as possible I'll add a JIRA ticket for both things (in this
moment our JIRA is down for maintenance) ...
Bye,
Sandro

Yes. From the README:

license and is available here:

Hi
I tried to display SVG images, but I got a ClassNotFoundException for com.kitfox.svg.SVGDiagram:

Is another jar required beside the binary distribution?

Re: How parse a JSON to List
Posted by Greg Brown <gk...@verizon.net>.
GSON will work, but Pivot's JSONSerializer class will output Pivot data types such as Sequence and Dictionary that can be used as model data (e.g. to back a list or table view).
If you want to deserialize JSON into a bean, you just need to pass the bean type to the JSONSerializer constructor.

They're not part of Pivot, but Google Gson and, for Scala, Lift's JSON
lib[1], can both do this nicely.
Gson makes use of the gnarly "type-token" idiom to work around type
erasure when unmarshalling things like List<Bean>, but the gnarliness is
Java's fault, not Gson's.
[1] This came out of the Lift webapp framework, but is standalone.

In those tests we don't have anyone testing the java.util.Date class.
It's will work fine too?
I'm getting this exception:

Vanio,
Take a look at

and the other related JSON test files
