Re: Struts 2.0.11.1 question
Great discussion, but just to give some background on my OT: - Blessed Struts ver. is 2.0.11.1. This does not have the JSON plugin which I think was included only in 2.1.7 - I have used GSON, and I was very impressed. Marshalling/UNMarchalling JSON is literally 1 line of code if the model classes are set right. Great tool to use if you can. - I think I will go with the JSON implementation @ www.json.org/java , which is not as slick, but importantly for me is blessed - I would say that if a product is licensed esp. with a license like Apache 2 (Struts, GSON and a whole lot more), it would be easier to get something approved. Unfortunately, its not. I repeat again, its not. Even if my manager likes it, its not. :-D I laugh because I cry inside.

From your examples it should probably have a Struts Result object wrapped around it to make it easier to use, but that's beside the point. horse level=high status=on My problem is companies that are short sighted enough to think that spending developers time to produce libraries of code that are not directly related to their core business (like a medical or insurance company building a JSON library) is going to be a good thing for their bottom line. It's not! It's going to add development and maintenance tasks to their projects that take away from developing new and better features that would enhance their core business proposition. As developers, when we are presented with a new projects we need to separate the core business aspects of the project from the purely technological aspects. We then need to do a little research to find the best fitting, most mature tool to accomplish the technical goals and champion that as the way to spend more time on the business differentiating goals of the project. Once they see they can get more features in less time for less money, they'll come around. /horse type=dead reason=kicked On Wed, Mar 9, 2011 at 8:34 AM, Paul Zepernick pzepern...@commercebenefitsgroup.com wrote: We are using the Google Gson project to handle converting our objects / maps to json.

De-serialize JSON to Action
I have been working with the Struts 2 JSON plugin and I have got it set up so that I can serialize my Java beans as a JSON string and pass it along to the browser. Is the reverse possible using the plugin? That is, if I have a JS widget (Dojo, in this case) that spits out JSON, can I read in the JSON string and de-serialize it to a Java bean? I would appreciate it if someone could point me to a best-practice for doing so. -- *Thanks, Harsh*

Re: De-serialize JSON to Action
I would think probably not because at runtime, the JVM would need to know
the type of the objects in the list. But its late here, and I haven't given
it much thought.

Hello,
I was wondering about how to do this, and I just saw your mail. The post
is interesting and useful, but I was wondering if it is possible to
automatice the conversion for beans. According to the documentation(
http://struts.apache.org/2.2.1.1/docs/json-plugin.html) a list of beans
will
be mapped to a List of Maps. For example, let's say I receive the following
JSON into my action:
{identifier:name,
items:[
{
accessLevel:NO_ACCESS,
desc:Officers,
name:ECO Officer,
type:ROLE
},{
accessLevel:NO_ACCESS,
desc:Publications,
name:ECO Publications Manager,
type:ROLE
],
targetIdBox:17101}
As required by the json plugin, I would need to define a
setIdentifier(String), setTargetIdBox(int), and a setItems(ListMap). That
works correctly, but I would like to automatice the conversion from a Map
to
a bean. Is it possible?
Thanks

AJAX file upload

Specify template to use for struts tag
Is there a way to specify a template to use for a struts tag, on a per tag basis e.g. I am trying to change the checkboxlist default LF so that it renders in a table. This is working fine. But if I want to use the default LF also, how do I do that. As of now, I copied the struts provided .ftl files and messed around with them. Can I create my own template and then specify something in e.g. s:checkboxlist to use a different template to render the check box list? -- *Thanks, Harsh*
Re: Specify template to use for struts tag

Re: Struts2, convention plugin, websphere 6.1
Hi,
I have an input page which has a checkbox list in a form. Clicking submit
takes the user to a 2nd JSP.
The problem is that when I don't select a checkbox and click on submit, I
get to the output page, of course no value is displayed on the output page
though.
But if I select a checkbox and click submit, I get an error saying
No result defined for action .action.ModelHomeAction and result input
I just started with struts and don't really know why it is looking for the
result input. I would appreciate any help with this.
Relevant code is below.

}

Re: Struts2, convention plugin, websphere 6.1
So, result input is some kind of default result that struts sends a user
to?
Is validation turned on by default, as I did not specify any validation? If
so, how can I turn it off?

Re: Struts2, convention plugin, websphere 6.1
I think that is probably what it was. Basically in my action, I had a list
of model objects (modelList) and a model object (selectedModel).
I changed the Model type object selectedModel to String type selectedModelId
and things work fine now.
Now my question is, if I had a checkboxlist backed by a list of Model
objects, and upon checking some models, I wanted a list of selectedModel
objects, is there a way in struts to do it?
Thanks,
