Store a variable in the session

Hi, i'm working with jsp+struts.
I can't store, from an ActionServlet, a variable in the session.
I want store a String in the session. I write in the ActionServlet : request.setAtribute ("popo").
I can't recover the value of the variable. I try : request.getAtribute ("popo",aux);
Any solution???
Thanks
Hola! Estoy trabajando con jsp + struts. No consigo almacenar, desde un ActionServlet, una variable en la sesion.
Quiero almacenar un String en la sesion, y lo hago mediante: request.setAtribute, pero luego no me recupera el valor desde un jsp, mediante request.getAtribute.
Alguna soluci�n???
Gracias

use a java class, make it simple, I just threw this together so might have typos:
class MyStorage{
private String myValue;
public MyStorage(){
myValue = "";
public void setValue(String what){
myValue = what;
public String getValue(){
return myValue;
In the jsp do:
HttpSession sess = request.getSession(true);
MyStorage safeKeeper = (MyStorage)sess.getAttribute("MySafeKeeperName");
if(safeKeeper = null){
safeKeeper = new MyStorage();
sess.setAttribute(safeKeeper,"MySafeKeeperName");
safeKeeper.setValue("Some Stupid Value");
out.println(safeKeeper.getValue());

How can i view the variables of the session memory

Hi experts
How can i view the variables of the session memory.Such as I want display the variables of memory which id is 'BULRN' in ABAP debug.
In program i can use import from memory id visit the momery of session,but i don't know the name of variables which store in momery of my session.

Its not possible to view in the debug mode..
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table TPARA.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.
export itab to memory id 'TEST'.
import itab from memory Id 'TEST'.
Here itab should be declared of same type and length.

How to store forms fields into the session ?

Hi All,
I have to store forms fields into the session.
I have four forms (htm forms) in four jsps and there are total 25 fields.
I am inserting all the fields into the database at once while user submit the last form.
I want to use session to store forms fields.
So please anybody tell me how to do that.
Is the following code correct to store the forms fields into
the sesstion........
// creating a session
HttpSession session=request.getSession(true);
// retrieving form fields
String name=request.getParameter("customer_name");
String business=request.getParameter("business");
String address=request.getParameter("address");
and so on....
// store form fields into the session
session.setAttribute("name",name);
session.setAttribute("business",business);
session.setAttribute("address",address);
and so on....
and later on get the value as:
session.getAttribute("name");
session.getAttribute("business");
session.getAttribute("address");
and so on....
OR
is there another way to store form fields into the session.
Please guide and reply with coding.....
Please answer and help.
Thanks

I don't mean to be an *** but I have no desire to help someone so unwilling to think >>and do. Go through some of these tutorial, do the examples in each and you will be far >>better equipped to ask questions:
http://www.google.co.za/search?hl=en&q=%2Bjsp+%2Bjavabean+%2Btutorial&b >>tnG=Google+Search&meta=
I was just asking that if I use the following
<jsp:useBean id="cart" scope="session" class="session.Carts" />
<jsp:setProperty name="cart" property="address" value="myaddress" />
</jsp:useBean>then will I be able to acheive my aim as I have to store form fields into the session and later retreive while user submit the last form.
Please read my question that I have posted.
Am I using the right way................or which is the best way to store form fields into the session and later retrieve them.

Save XPRESS Variable to the session

Is there a way to save a variable within an XPRESS workflow to a session? I would like to have XPRESS generate some data, save it to the session, then send the user to a customized JSP that can pull that saved session data.
Any way to do this???
Thanks!

Hi: thanks for looking at it.
Actually, I am not calling the save as in my script, the user is clicking on Save As and the event listener I have in the start up folder is picking that up. The event listener calls up a script that asks users to fill in a couple of fields about the specific job and once they do that and click ok, the default inDesign "save as" dialog is brought up. So that is my question -- how to pass the information from my dialog to the standard "save as" dialog (as the file name of the file).
The event listener is of the beforeInvoke on the Save As... menu.
Any idea?
thanks!!

How to Set and Use a global variable within a session?

Dear All,
I'm new to jsp, and would like to ask how to set and use a global variable within a session?
Thanks in advance.
Regards,
Cecil

With session.setAttribute("name",object) you can store a Attribute in the session object.
with session.getAttribute("name") you can get it.
That's it.

Getting all variables from a session

I can put and get variables into the session no problem, however I would like to get a list of all the objects stored in the session - is their a quick way to do this ?

You can use the getAttributeNames() method of HttpSession, which returns an enumeration of the names of all the objects in the session

Request variable not overriding session variable in report filter

I have a dashboard edit prompt that saves value into a request variable with same name as session variable.
The session variable has "enable any user to set the value".
I have a filter in the report that has been converted to sql where the transaction date is greater than the value entered in the prompt.
I see the "SET Variable" clause at the top of the sql being sent to the server in the logs.
However, when I am in "View Logs", I see that the sql that is being sent to the database is sending the original value of the session variable instead of the new value in the request variable.
I have tried using VALUEOF(NQ_SESSION.variablename), VALUEOF(variablename), VALUEOF("Dynamic Initialization Block Name"."variablename"), @{biServer.variables['NQ_SESSION.variablename']} with no difference.
What am I doing wrong?

Thanks.The session attributes are available via the "sessionMap" property of the ExternalContext for this request. So, from within your Action, you could do something like this:
User user = ... set up your user object ...;
// Get FacesContext for this request
FacesContext context =
FacesContext.getCurrentInstance();
// Store user object in the session map
context.getExternalContext().getSessionMap().put("user", user);Craig McClanahan

How to clear the variable value in session store?

I'll try to build form for search. There are LOV and
search button on form. When user don't select anything then push
search button, I'd like the report to show query everything. I
mean the report will show like condition where id like '%'.
And I send variable between form to report by using session
store.
I select nothing in LOV but value that return by LOV is
not null. It's in stead of old value of LOV.
Please tell me.. How to clear the variable value in
session store? I'd like to set it to null. If you have greater
way to do like this, please tell me.
Thank you.

Please suggest on this..
Thanks.

How to pass a session variable to the bussines layer?

Hello,
I am doing a management application, and I need to store the login user that make insertions on any table, and the pages does not has backing beans.
I had try to do that bindding the value field of a hidden attribute with the session variable, but it only change the value of the one. My second attempt was make an javascript function to do that on the page´s load, but it not looks like a good solution.
Someone knows a way to sent the session value to the bussines layer? O a way to access from the Bussines layer to the session?
Thanks
Tony

<p>
Hi,
</p>
<p>
Another solution (that I always use) is storing simultaneously the same data in HttpSession (in view layer) and session hashtable (in businness layer).
</p>
<p>
You can put and get these data in any businness component using following methods:
</p>
<p>
<font face="courier new,courier" size="2" color="#0000ff">
private void setToJboSession(String key, Object val){</font>
<font face="courier new,courier" size="2" color="#0000ff"> Hashtable userData = getDBTransaction().getSession().getUserData();
if (userData == null) {
userData = new Hashtable();
userData.put(key, val);
}</font>
</p>
<p>
and
</p>
<p>
<font face="courier new,courier" size="2" color="#0000ff">
private Object getFromJboSession(String key){
return getDBTransaction().getSession().getUserData().get(key);
}</font>
</p>

Trying to move a list of form variables to session variables of the same name

I am trying to move a list of form variables to session variables of the same name and I am having a lot of trouble.
I have never had to post of this forum with a language question in all the 10 years I have been using ColdFusion. I was a qa Engineer @ Allaire/Macromedia back when it was going from one to the other. I have a pretty good grasp of the language.
I have software that runs off a list. The fieldnames are variable and stored off in an array. It's survey software that runs off a "meta file". In this example; I have the number of fields in the survey set to 12 in the "metafile". I have each field declared in that file in array Session.SurveyField[1] and the above loop works fine. I include this "metafile" at the start of the process.
I cfloop around a struct and it works wherever I have needed to use it; such as here - writing to the database for example;
<CFQUERY NAME="InsertRec" DATASOURCE="Survey">
INSERT into #variables.SurveyTableName#
(EntryTime
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
,#Session.SurveyField[arrayindex]#
</cfloop>

   VALUES
    ('#EntryTime#'
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thisname = "Session." & Session.SurveyField[arrayindex]>
,'#evaluate(variables.thisname)#'
</cfloop>

</CFQUERY>
NOW HERE'S THE PROBLEM: I am running into trouble when trying to move the form variables to session variables of the same name. It is the only part of the software that I still need the datanames hard coded and that is a roadblock for me.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thissessionfield = "Session." & Session.SurveyField[arrayindex]>
<cfset thisformfield = "Form." & Session.SurveyField[arrayindex]>
<cfset #thissessionfield# = #evaluate(thisformfield)#>
</cfloop>
I have tried it with or without the "evaluate"; same result. It doesn't give an error; it just ignores them (session variables look as such in the next page in the chain)
q01_name=
q02_acadtechorna=
q03_water=
q04_firstaid=
q05_cpr=
q06_lifeguard=
q07_aed=
q08_projadv=
q09_color=
q10_santaclaus=
q11_supervisor=
q12_supervisoropinion=
Note: they exist because I CFPARAM them in a loop like the above at the start of the procedure) - and this works just fine!
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset dataname = "Session." & Session.SurveyField[arrayindex]>
<cfparam name="#variables.dataname#" default="">
</cfloop>
</cflock>
I EVEN tried exploiting the Form.Fieldnames list using CFLoop over the list and the same sort of logic within and it still gives me nothing....
Here's the FORM.FIELDNAMES value
"Q01_NAME,Q02_ACADTECHORNA,Q03_WATER,Q04_FIRSTAID,Q05_CPR,Q06_LIFEGUARD,Q07_AED,Q08_PROJAD V,Q09_COLOR,
Q10_SANTACLAUS,Q11_SUPERVISOR,Q12_SUPERVISOROPINION"
Here's the logic; SAME RESULT - The session variables don't get set.
<cfoutput>
<cfloop list="#Form.FieldNames#" index="thisfield">

<cfscript>
thisSESSIONfield = "Session." & thisfield;
thisFORMfield = "Form." & thisfield;
#thisSESSIONfield# = #thisFORMfield#;
</cfscript>
</cfloop>
</cfoutput>
The CFPARAM in a loop with variable output name works just fine; so does the post (which I included above) as does the SQL Create, Param Form Variables, Param Session Variables, etc.
THIS even works for moving BLANK to each session variable, to zero them all out at the end of the process;
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
</cfscript>
<cfset #thissessionfield# = "">
</cfloop>
</cflock>
Expanding on that code, you would think this would work, but it doesn't;
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
thisformfield = "Form." & thislocalfield;
</cfscript>


<cfoutput>
<cfset #thissessionfield# = "#evaluate(thisformfield)#">
</cfoutput>
</cfloop>
And see that debug code in the middle? To add insult to injury... When I uncomment that it shows me this. So it certainly looks like this should work....
Session.q01_name = "Me"
Session.q02_AcadTechORNA = "N/A"
Session.q03_Water = "Yes (certificate expired)"
Session.q04_FirstAid = "Yes (certificate is current)"
Session.q05_CPR = "No"
Session.q06_LifeGuard = "Yes (certificate expired)"
Session.q07_AED = "Yes (certificate expired)"
Session.q08_ProjAdv = "Yes (certificate expired)"
Session.q09_Color = "Gray"
Session.q10_SantaClaus = "Yes"
Session.q11_Supervisor = "Da Boss"
Session.q12_SupervisorOpinion = "Not a bad thing"
There must be some simpler way to do this. This way won't work against all odds even though it seems so much like it should.
So I end up having to hardcode it; still looking for an automated way to set these #@%$*@!## session variables over the list from the form variables of the same @#@!$#%$%# name. Do I sound frustrated???
No matter what I do, if I don't HARDCODE like this;
<cfset Session.q01_name = Form.q01_name>
<cfset Session.q02_AcadTechORNA = Form.q02_AcadTechORNA>
<cfset Session.q03_Water = Form.q03_Water>
<cfset Session.q04_FirstAid = Form.q04_FirstAid>
<cfset Session.q05_CPR = Form.q05_CPR>
<cfset Session.q06_LifeGuard = Form.q06_LifeGuard>
<cfset Session.q07_AED = Form.q07_AED>
<cfset Session.q08_ProjAdv = Form.q08_ProjAdv>
<cfset Session.q09_Color = Form.q09_Color>
<cfset Session.q10_SantaClaus = Form.q10_SantaClaus>
<cfset Session.q11_Supervisor = Form.q11_Supervisor>
<cfset Session.q12_SupervisorOpinion = Form.q12_SupervisorOpinion>
I always get this from my next page because the session variables are empty;
You must answer question 1.
You must answer question 2.
You must answer question 3.
You must answer question 4.
You must answer question 5.
You must answer question 6.
You must answer question 7.
You must answer question 8.
You must answer question 9.
You must answer question 10.
I tried duplicate as well, but I can not get the above to work...
Can anyone help me do this thing that one would think is simple????

I think if you use structure array syntax you should get the results you want.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
      <cfset session[Session.SurveyField[arrayindex]] = Form[Session.SurveyField[arrayindex]]>
</cfloop>
Or probably even easier.
<cfset session = duplicate(form)>

Using Session Variable in the Column Level Security

My Question -
1. I created an initialization block with initialization string by calling a new session variable CTP_ID_LIST in the sql command, given appropriate database connections and when I exit out of Block, and chosen Row-wise initialization. I do not see a new session variable created under variables list. Why does this happen? Please help me on this.

Hi,
This happens when you select Row-wise Initialization.
The row-wise initialization feature allows you to create session variables dynamically and set their values when a session begins. The names and values of the session variables reside in an external database that you access through a connection pool. The variables receive their values from the initialization string that you type in the Initialization Block dialog box.
You can also use the row-wise initialization feature to initialize a variable with a list of values. You can then use the SQL IN operator to test for values in a specified list.
Example: Using the table values in the previous example, you would type the following SQL statement for the initialization string:
select 'LIST_OF_USERS', USERID
from RW_SESSION_VARS
where NAME='STATUS' and VALUE='FULL-TIME'
This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE; for example, JOHN:JANE. You can then use this variable in a filter, as shown in the following WHERE clause:
where TABLE.USER_NAME = valueof(NQ_SESSION.LIST_OF_USERS)
The variable LIST_OF_USERS contains a list of values, that is, one or more values. This logical WHERE clause expands into a physical IN clause, as shown in the following statement:
where TABLE.USER_NAME in ('JOHN', 'JANE')
