Separate Java Bean Class for Getter/Setter method.
I am trying to develop a small struts apps. I want to write all the setter
and getter method in a separate Bean file and want to keep the controller
clean :) If we remem, struts 1.2 style.
I dont want to use viewname.elementname style. This create a issue in the
javascript validation. As JS is not able to recognize the "." dot.
<s:textfield id="alName" name="objAllergyView.alName"/>
<s:textfield id="alDescription" name="objAllergyView.alDescription"/>
Thanks,

Here is my whole code. implement ParameterAware.
Declaration of MAP.
Map<String, String[]> parameters = null;
Call this method.
getParameters("alId")
public void setParameters(Map<String, String[]> params) {
// TODO Auto-generated method stub
this.parameters = params;
}
public String getParameters(String param) {
StringBuffer sbVal = new StringBuffer();
paramVal = (String[]) parameters.get(param);
for (int i = 0; i < paramVal.length; i++) {
sbVal.append(paramVal[i]);
}
return sbVal.toString();
}

Yes, the map is Map<String,String[]>. Because the HTTP protocol allows
sending multiple parameters with the same name.

I also tried Map <String String>. But the same result.
.toString also does not help any thing. It looks like the Parameter from
request is returning
Map<String , String[]>.
Later If i run the value as String array I get the value. The length is
always sets to 1.
String st[] = map.get("param");
value = st[1];
This gives me the exact value. This extra code I am writing in every action
class.
Any better solution ?

You have to override the Object's toString method. Why is your map
holding a Object? Should be one of your classes.

Now the URL looks like, No extra amp;
http://localhost:8080/Samvidh_CIS/doEditAllergy.action?alId=2&alDescription=algy_full_desc&alName=algy_short_desc
Now the New problem is that, I am not able to retrieve the value of the key
though I am able to see the key.
Code in Action Class-
Map<String, Object> map =
ActionContext.getContext().getParameters();
Iterator entries = map.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry entry = (Map.Entry) entries.next();
String key = entry.getKey().toString();
String value = entry.getValue().toString();
System.out.println("Key = " + key + ", Value = " + value);
}
Console Output.
Key = alDescription, Value = [Ljava.lang.String;@b90a6e
Key = alId, Value = [Ljava.lang.String;@b4b0a4
Key = alName, Value = [Ljava.lang.String;@5bcd91
Help Please...

Sure.
* Is it "al", or "all"? You show both. IMO that's a bad idea--too
similar if they're supposed to be different.
* You say you pass three, get one. Which one?
* You say you pass three, get one; I only see two references to parameters.
* Is the URL being constructed properly? Check the HTML source.

I dont know if its a bug or functinoality. I am passing 3 param from a page.
I am only able to receive the 1st one in the next page... Dont know why.
Page one :-
<s:url action="doEditAllergy" id="url">
<s:param name="alDescription" value="%{#view.alDescription}" />
<s:param name="alId" value="%{#view.alID}" />
<s:param name="alName" value="%{#view.alName}" />
</s:url>
Page two :-
<label for="alDescription">Description</label>
<s:textfield id="alDescription" name="alDescription"
value="%{#parameters.alDescription}"/>
</p>
<p>
<label for="alEnabled">Enable this Allergy ?</label>
<s:checkbox id="alEnabled" name="alEnabled" value="true" />
</p><p>
<s:hidden name="alID" value="%{#parameters.alId}"/>
Any feed back ?

Thanks for the reply. I had tried the same thing and again removed. Will
there be any dis/adv if I use this Model class ?
Another question is how can i pass/retrieve a parameter in my action class ?
http://localhost:8080/Samvidh_CIS/doEditAllergy.action?allergy.Id=1002
I want this allergy.Id=1002 value in action controller so that I can query
the DB to read the necessary data.

Hi,
If you want to keep the bean in a separate class then your action class that
needs to implement two interfaces Modeldriven and Preparable. Its called
model driven approach in struts 2
class MyBean
{
// attributes
// getter and setter
}
class MyAction extends ActionSupport implements ModelDrive, Preparable
{
MyBean myBean;
public Object getModel()
{
return myBean;
}
public void prepare()
{
myBean = new MyBean();
}
}
}
This is beautifully explained in the book Struts 2 black book on page
number 435. please find at
http://books.google.co.in/books?id=-V86IiyqZ_YC&pg=PA357&lpg=PA357&dq=struts2+black+book+model+driven+and+preparable+example&source=bl&ots=riNsAvbHwX&sig=NclG8_JKyS3sKH6taJFCKgmjGvQ&hl=en&ei=MF3KTe2DN4nNrQemwLCJBQ&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBgQ6AEwAA#v=onepage&q&f=false
