problems with struts2 and session
Hi people,
i'm a newbie to struts2. I'm having too many problems modifing session
parameters. I use <%= session.getAttribute( "variable" ) %> to gain
access to "variable" and that works when i modify "variable" into a jsp
page, but not inside a struts action.
struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="tads" namespace="/" extends="struts-default">
<action name="HolaMundo" class="tads.HolaMundo">
<result>/holaMundo.jsp</result>
</action>
<action name="Catalogo" class="tads.Catalogo">
<result name="error">/ErrorCatalogo.jsp</result>
<result>/Catalogo.jsp</result>
</action>
<action name="Actualiza" class="tads.Actualiza">
<result>/Actualiza.jsp</result>
</action>
</package>
</struts>
extract from a jsp page, result from an ajax action working:
<s:form id="form" >
<s:textfield name="politico" label="politico"/><br>
<s:hidden name="prueba" value="escondido" />
</s:form>
<s:url id="actualiza" value="/Actualiza.action" />
<sx:submit type="button" label="dale" href="%{actualiza}" formId="form"
align="center" targets="secondaryContent"/>
i see "politico" and "prueba" into Actualiza.action so the action
Actualiza works.
Actualiza.java:
package tads;
import java.util.*;
import javax.servlet.http.HttpSession;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionContext;
@SuppressWarnings("serial")
public class Actualiza extends ActionSupport implements SessionAware {
private String politico;
private String prueba;
private Map session;
public String execute() throws Exception {
this.getSession().put("variable","pruebamil");
return SUCCESS;
}
public String getPolitico() {
return politico;
}
public void setPolitico(String politico) {
this.politico = politico;
}
public String getPrueba() {
return prueba;
}
public void setPrueba(String prueba) {
this.prueba = prueba;
}
public void setSession(Map session) {
this.session = session;
}
public Map getSession() {
return session;
}
}
in that situation. Actualiza.jsp doesn't show "variable" atribute from
session, using "<%= session.getAttribute( "variable" ) %>". It shows null.
can anybody help me? I'm doing exactly what struts2 FAQ say (How do we
get access to the session).
thanks in advance.

Hi Sergio,
this time late answear,
when You have session field in action and also setter and getter for it
then You can access session map as any other field from action in jsp,
so < s:property value="session.get('variable')" > should work,
because it is accessing normal getter in stack.
Maybe try < s:property value="getSession().get('variable')" > to be
more accurate.
Best greetings,
Paweł Wielgus.

didn't work because the "get" method. Both "<%= session.getAttribute(
"variable" ) %>" and "<s:property
value="#session.variable"></s:property>" worked, but i had to close and
open eclipse. Bad memory management of eclipse i think.

Re: problems with struts2 and session

Hi,
sorry for too fast response,
i see that it is implementing it,
another thing to notice is that
in action You have access to session field which is a map constructed
by struts, not real session object - as far as i remember.
In jsp you can do < s:property value="session.get('variable')" > to
show key from session in jsp.
Hope that it will help,
Pawel Wielgus.

<%= session.getAttribute( "variable" ) %>
