1. I have "actionOne"
public class ActionOne extends ActionSupport implements ServletRequestAware{
protected HttpServletRequest request;
private SearchParameter searchData=new SearchParameter();//My complex
object
public String execute() throws Exception{
//fill searchData with parameters. Many many parameters.....
return this.SUCCESS;
}
// this is for ability to copy object searchData to next chain action
public SearchParameter getSearchData() {
return searchData;
}
public void setServletRequest(HttpServletRequest httpServletRequest) {
request = httpServletRequest;
}
}
2.
<package name="searchEngine" namespace="/s2examples"
extends="struts-default">
<action name="*search" class="s2.action.ActionOne" method="{1}" >
<result name="success" type="chain" >doSearch</result><!--to search
-->
<result name="input" >search.jsp</result> <!--input -->
</action>
<!-- специально сделана отдельно, чтобы на нее наложить execAndWait -->
<action name="doSearch" class="s2.action.ActionTwo" >
<interceptor-ref name="completeStack"/>
<interceptor-ref name="execAndWait">
2000
500
</interceptor-ref>
<result name="wait">wait_search.jsp</result>
<result name="success" type="redirect" >search_result.jsp</result>
</action>
</package>

public class ActionTwo extends ActionSupport implements ServletRequestAware
{
protected HttpServletRequest request;
private SearchParameter searchData;
private HttpSession sess;
public String execute() throws Exception{
sess = request.getSession();
boolean v =(searchData!=null);// ok. we recieve a copy of searchData
from previos action
try { Thread.currentThread().sleep(6*1000); } catch
(InterruptedException ex) {}
sess = request.getSession(); // return null object!!! why ?
return this.SUCCESS;
}
/*this work and searchData object has been copied from previos action */
public void setSearchData(SearchParameter searchData) {
this.searchData = searchData;
}
}
The desired behaviour:
public class ActionTwo extends ActionSupport implements ServletRequestAware
{
protected HttpServletRequest request;
private HttpSession sess;
public String execute() throws Exception{
SearchParameter searchData=null;
try { Thread.currentThread().sleep(6*1000); } catch
(InterruptedException ex) {}
//!!!!
ActionOne prev=null;
prev=(ActionOne)getPreviousAction();
searchData=prev.getSearchData();
//!!!!
sess = request.getSession(); // return null object!!! why ?
return this.SUCCESS;
}
}
===============================================================
for simplisity simplicity searchData may be a simple Object().
I need an ability to make : prev=(ActionOne)getPreviousAction();
