session scope tool - write a new one

[Gil Vernik]

Hello everyone,

I am trying to write a class that will read some values from properties
file into array and then store this array in the user session.

 

I want to do it using toolbox.xml,

I created an entry 

                <tool>

            <key>localeData</key>

            <scope>session</scope>

            <class>com.test.LocaleDataReader</class>

      </tool>

 

And the class LocaleDataReader is 

 

public class LocaleDataReader {

    public void init(Object obj)

    {

        HttpServletRequest request = ((ViewContext)obj).getRequest();

    }

public LocaleDataReader(){}

 

    public ArrayList<String> getCurrentABC(){

            ArrayList<String> currentABCtmp = new ArrayList<String>();

// will read locale properties file, for now only

            currentABCtmp.add("value");

      return currentABCtmp;

 

    }

 

}

 

 

Here is the question :

A.  How can I store currentABCtmp variable into the session, so next
time the call getCurrentABC() will return value from session. How can I
access the session from this Method.

B.  Why init() is never called? Who should call it? I saw init() in the
source of some tools, I thought that how I can get access to session.

C.  I don't see any difference using debug between request and session
scope of the entry in toolbox.xml, why is it?

 

Thanks a lot,

Gil.
