Issue in Action Chaining
Hi All,
I have a Action class
class BaseAction extends ActionSupport {
private Sting data;
public void getData() {
return this.data;
}
public String setData(String data){
this.data = data;
}
}
class Action extends BaseAction{
public String execute() throws Exception {
System.out.println(getData());
setData("abc");
return "chain";
}
public String executeChain() throws Exception {
System.out.println(getData());
return "success"
}
}
xml configuration:
<action name="test" class="Action">
<result name="chain">test2</result>
</action>
<action name="test2" class="Action" method="execute1">
<result name="chain"></result>
</action>
http://localhost:8080/test/test.action?data=ball
Output of execute: ball
Output of execute1: ball
I am expecting the out of execute1 as "abc"
Am I missing something please help me resolve the issue.
Rgds,
Satya
AW: Issue in Action Chaining
Posted by Anastasios Patrikis <An...@prodyna.de>.
Hi Satya,
in our project we have a base action with methods to read/write session attributes:
ServletActionContext.getRequest().getSession.getAttribute(name)
ServletActionContext.getRequest().getSession.setAttribute(name, object)
This may help.
Regards,
Anastasios.

Betreff: Re: Issue in Action Chaining
Hi Wesw,
I also tried printing the object address and what you said is right!! It is
creating a new object. The object address is not same. Is there any other
way of passing the data to the chained method?
I want to use the redirect as the last option!!
Rgds,
Satya

Hi Wesw,
Thanks for the reply. Yes, I meant to say testChain(). Thanks for that.
So, how is the old data being retained. Does it take it from the http
request and recreates the new instance?
If that is the case, what other options do I have to get the changed data
into the chained method?
Thanks
Satya

The configuration of test2 points to method execute1, but your action has
executeChain(). I assume that's a typo. My (somewhat educated) guess is that
when you chain to the next action, even though it is the same class, a new
instance is created. In the new instance, setData(String) is never called
since it is only called in the execute method.

No it doesn't work. Chain is not accepting any of the parameters strings.
Its going to the global error page directly.

I'm not sure if this applies to the chain result, but you could give
it a shot: http://struts.apache.org/2.1.6/docs/parameters-in-configuration-results.html
