Newbie Q: How to set session object parameters in struts.xml

Hello,

Is it possible to set session objects inside and action and access the
session object in another action without explicitly retrieving the
session object?

Thanks,
J

To be clear with previous post, first try to parse data then put it on
the stack.

Hi,

I misunderstood you ;-) I spent some time to find solution but right
now it isn't possible because of StaticParametersInterceptor. Look at
the code below

            for (Iterator iterator = parameters.entrySet().iterator();
                 iterator.hasNext();) {
                Map.Entry entry = (Map.Entry) iterator.next();
                stack.setValue(entry.getKey().toString(),
entry.getValue()); // exception here if you try something like you
                Object val = entry.getValue();
                if (parse && val instanceof String) {
                    val = TextParseUtil.translateVariables((String)
val, stack); //
                }
                stack.setValue(entry.getKey().toString(), val); //
duplicated, it should be only once
            }

In my opinion it should be changed to this, removed duplicated entry

            for (Iterator iterator = parameters.entrySet().iterator();
                 iterator.hasNext();) {
                Map.Entry entry = (Map.Entry) iterator.next();

// it's duplicated
//stack.setValue(entry.getKey().toString(), entry.getValue());

                Object val = entry.getValue();
                if (parse && val instanceof String) {
                    val = TextParseUtil.translateVariables((String)
val, stack); //
                }
                stack.setValue(entry.getKey().toString(), val); //
duplicated, it should be only once
            }


and one thing, you should put parse param on interceptor, not on action

            <interceptor-ref name="staticParams">
                <param name="parse">true</param>
            </interceptor-ref>
            <param name="cardNo">${params.myid}</param>

No.

The previous answer, implementing SessionAware, was one of the correct answers.

I have implemented sessionAware and the process works for a static
string but it doesn't work for objects :(

So I have the following in my struts.xml:

        <action name="blah"
            class="blahAction">
            <param name="parse">true</param>
            <param name="test">hello</param>
            <param name="something">${something}</param>
            <result>out.jsp</result>
        </action>

the "test" param works fine which is a simple string but the the other
param "something" does not work.

Does the syntax ${something} retrieve the object from the session?

Implement SessionAware interface with yours actions and put and get
value from that map ;-)
