Yes. JXPath is used.
The names are matched by JavaBean introspection.

Thanks Alonso.

I have read userIdentity.xml and UserBean.java files from Cocoon Wizard
sample.
In UserBean.java, I have found a method called "initHobbies()". This method
simply init all hobbies.

If I have well understood, I could replace the hard-coded values of
allHobbies by a query to a database. isn't it?

What would be the solution if I want to retrieve the allHobbies values from
an external xml file?
Is there an example?

Thank you
Sylvain

Hello.

I had a very similar problem a few days ago. The way to go is the itemset
tag as used in the wizard demo. Take a look at the 'userIdentity.xml' file
where the Hobbies get listed:

Hobbies






All you have to do is to change the UIType to the one desired and fill the
items with values taken from the DB, for example from the action.

Hope it helps,
Josema.

RE: XMLForm: dynamic content listbox

[Josema Alonso]

When you say 'So, but how is the xmlform framework determining the name?' I
do not know exactly what you mean.

Maybe you need the help of someone more expert than me in the framework. As
I told you in my previous message I think is JXPath making the mappings, but
haven't investigate this point too much...maybe we should take a closer look
at http://jakarta.apache.org/commons/jxpath/...

thanks Josema,

after playing a while I found it as well, but still find it a bit
confusing, because there is now direct reference. What I did was
the following:


 public UserBean () {
initCustomers();
 }

 public String[] getName() {
return names;
 }

 public void setName( String[] newNames ) {
names = newNames;
 }

 public Set getCustomerNames() {
return customerNames.entrySet();
 }

 public void initCustomers() {
names  = new String[] {};
customerNames  = new HashMap();

...
  fill with database entries
...
 }


after this was done in the java bean, I could acces the elements
by using /name as ref value in the xml file.


 
  Customer
  
   
   
  
 


So, but how is the xmlform framework determining the name?

best regards
Lars Kirchhoff

Hi,

For what I know, the access to the properties by JXPath relies on the getter
and setter methods. So if you read the code in UserBean.java you'll see:
  public String[] getHobby()
  {
return hobbies;
  }

  public void setHobby( String[] newHobbies )
  {
hobbies = newHobbies;
  }

And that's why is accesssed via /hobby.

Please, Ivelin or anyone else, correct me if I'm wrong.

Hope it helps.

Hello,

I'm trying the same and did manage to create a dynamic list
of checkboxes from a database. But I still don't get it completely.
Where is the ref="/hobby" defined? I looked in the UserBean and the
userIdentity.xml, but found nothing. Can somebody give me a hint.
I would like to change this to one of my own variable names.

regards Lars

Ok, I'll send the example later this evening.

Well, mostly...let's say you can get XML documents from Xindice. Think about
it as a XML documents repository that are stored in collections.

You're welcome.

Yes. Just fill the appropriate Java structure of your choice with the
database values after querying it.

>Is there an example?
Well, I'm using Xindice as the backend DB. I'm using DOM nodes to load the
content from the DB and then map those nodes to the form (there's an example
in the wizard with DOM nodes, too). It took me some time to make it work but
I know I get it. I do not have the code right here, but could send you a
complete example later today if you're interested.

Best.
